LGBT people in prison

From Wikipedia, the free encyclopedia
 
In some prisons, the only protective custody available to lesbian, gay, bisexual, and transgender people is segregated isolation.

Lesbian, gay, bisexual, transgender and queer (LGBTQ) people face difficulties in prison such as increased vulnerability to sexual assault, other kinds of violence, and trouble accessing necessary medical care. While much of the available data on LGBTQ inmates comes from the United States, Amnesty International maintains records of known incidents internationally in which LGBTQ prisoners and those perceived to be lesbian, gay, bisexual or transgender have suffered torture, ill-treatment and violence at the hands of fellow inmates as well as prison officials.

One US-based human rights organization describes LGBTQ inmates as "among the most vulnerable in the prison population." In California prisons, two-thirds of LGBTQ people report that they were assaulted while incarcerated. The vulnerability of LGBTQ prisoners has led some prisons to separate them from other prisoners, while in others they are housed with the general population.

Historically, LGBTQ people in the United States have been socially and economically vulnerable due to their queer status. Policy, policing and the criminal justice system have historically perpetrated violence upon marginalized populations, like the queer community. This along with criminalizing same sex behaviors have created a disproportion of LGBTQ people in prisons.

Rates of imprisonment

In the United States, LGBTQ individuals are incarcerated at a higher rate than the general population.

An analysis of data collected between 2011 and 2012 found that same-sex attracted adults were incarcerated at a rate of 1,882 per 100,000, more than triple the national average. This discrepancy was largely driven by a large overrepresenation of gay and bisexual women. The rate of gay or bisexual men in the prison and jail population (5.5% and 3.3%, respectively) was close to the national rate (3.6%), but the rate among women (33% in prisons and 26.4% in jails) was around 8 to 10 times higher than the national baseline. Similar patterns have been observed among Australian prisoners.

As of 2015, the National Center for Transgender Equality estimated that one in six transgender individuals in the United States has been incarcerated in their lifetime, whereas the Bureau of Justice Statistics estimates a rate of one in twenty for the overall population.

Coming out

Many LGBTQ inmates who are able, even those who are openly gay outside of prison, stay in the closet with their sexual identities while imprisoned, because inmates who are known or perceived as gay, especially gay men with stereotypical effeminate characteristics, face "a very high risk of sexual abuse".

The Los Angeles County Men's jail segregates openly gay and transgender inmates, however, only if they are openly gay and if the staff that is inspecting them perceives them to be gay or trans enough for segregation. Even through attempts from gay and trans men trying to seek a safer place, the jail only segregates those that fit into their definition of gay and trans, often only accepting those they deem vulnerable enough.

LGBTQ individuals are often subject to physical violence when they attempt to resist sexual abuse or sexual degradation, and can be targeted due to perceived femininity as well as if their sexual orientation is known. These individuals can be targeted because of their sexuality and attitudes towards LGBTQ people. In some instances, LGBTQ prisoners who are outed have been punished for attempting to repel an alleged aggressor, sometimes ending up in solitary confinement.

Denial of access to surgical sex reassignment on the grounds of unstable or criminal behavior condemns those who are transgender, resulting in potential continuing identity confusion, low self-esteem, drug and alcohol abuse, self-mutilation and acting out behavior which further facilitates the vicious cycle of chronic dysfunction, perpetuating criminal behavior.

Transgender issues

Some organizations that used to focus on women's issues have expanded to include transgender people and gender non-conforming people in their work. Certain actions can and do improve the lives of trans prisoners. The papers "Transitioning Our Prisons Toward Affirmative Law: Examining the Impact of Gender Classification Policies on U.S. Transgender Prisoners" and "The Treatment of Transgender Prisoners, Not Just an American Problem – A Comparative Analysis of American, Australian, and Canadian Prison Policies Concerning the Treatment of Transgender Prisoners and a 'Universal' Recommendation To Improve Treatment" maintain that individuals should always be addressed and placed based on their gender identity rather than their genitalia.

Australia

The bill mentioned in "Transgender Prisoners: A Critical Analysis of Queensland Corrective Services' New Procedure" has shown to be largely ineffective.

Canada

When Bill C-16, a bill that prevented discrimination based on gender identity, was passed in Canada, transgender prisoners were to be placed in facilities based on their gender identity. Additionally, Prime Minister Justin Trudeau promised to "look at" transgender prison assignment to ensure that these prisoners ended up in the facilities that matched their gender identity. Further, transgender prisoners are to be considered for sex-reassignment surgery if they are imprisoned for more than twelve continuous months.

Italy

In 2010 it was reported that Italy was to open its first transgender prison at Pozzale, a decision welcomed by gay rights groups. As of 2013, the prison has not been created yet.

Japan

One in 13 Japanese people identify as LGBT, or about 7.6% of the population. Japan does not criminalize same-sex sexual acts, and transgender people are able change their gender through the Family Registry if certain conditions are met. However these conditions include requiring "gender confirmation surgery, being over 20 years old, being unmarried while applying to legally change one's gender, having no minor children, and being deprived of their reproductive organ or reproductive ability" according to Amnesty International. If a person has not legally registered to change their gender before being incarcerated, they will be sent a prison that matches their gender assignment at birth. Additionally Japanese prisons are not required to provide hormone therapy for transgender inmates; since the medication is not to treat a disease, the prisons are not required by law to treat them. According to Amnesty International "Japan's Act on Penal Detention Facilities and Treatment of Inmates and Detainees (Act on Penal Detention) does not have specific clauses that cover the treatment of detainees based on sexual orientation or gender identity". However Article 34.2 of Act on Penal Detention requires that female prison officers examine female detainees, and the practice is also extended to transgender women regardless of their status with gender confirmation surgery or not.

United Kingdom

In 2019, the Ministry of Justice (United Kingdom) published data on transgender incarceration in England and Wales: there were 163 transgender prisoners (up from 139 reported in 2018), with 62 of the 121 jails housing at least one transgender prisoner. Prisoners are included in the data if they are being considered by a transgender case board, and known to be living in or presenting as a gender different from their sex assigned at birth. These figures may be underestimates in part because they do not include prisoners holding Gender Recognition Certificates under the Gender Recognition Act 2004.

Transgender prisoners in jails in England and Wales (2019) 
In By Male Female No response Total
Men's prisons legal gender 125 2 2 129
Men's prisons self-identified gender 0 119 10 129
Women's prisons legal gender 4 30 0 34
Women's prisons self-identified gender 20 11 3 34

In 2022, there were 230 transgender prisoners in Britain, increasing from 197 in 2021. In August 2022, a statement was issued by the Ministry of Justice under Dominic Raab, that trans prisoners would be sent to prisons based on their genitalia.

United States

Housing

Most U.S. prisons have a policy of housing prisoners according to their sex as assigned at birth or genital configuration (e.g. post-op trans women would be placed in women's prisons), regardless of their current appearance or gender identity. Transgender women with breasts may be locked up with men, leaving them vulnerable to violence and sexual assault, as occurred with the case of Dee Farmer, a pre-operative transgender woman with breast implants, who was raped and contracted HIV when she was housed in a men's prison. Transgender men housed in women's prisons also face abuse, often more from guards than other inmates.

U.S. prisons generally view gender and sex as binary; this includes prison dress codes, which prevent gender-nonconforming individuals from dressing to match their gender identity. There is often little gender-confirming healthcare provided. While transgender prisoners used to be permitted to be housed according to the gender with which they identify, this rule was reversed, as announced by the U.S. Bureau of Prisons in May 2018. Now, housing is once again to be determined by biological sex.

In 2013, Harris County, Texas adopted a policy intended to protect and assure equal treatment of gay, lesbian, bisexual and transgender inmates, which allowed individuals to be housed based on their gender identity. The policy also outlined how inmates are searched. It included a "safe zone project," meant to endorse a "positive relationship of solidarity" between the sheriff's department and the gay community. Another policy states that members of the transgender community will be referred to by their chosen name, even if it has not legally been changed, both when spoken to and on their identifications bracelets. The sheriff's office in Harris County has a training and certification program for staff members to be designated as "gender classification specialists," giving them authorization to discuss gender issues with inmates.

The New York State prison system (DOCCS) has revised policies in recent years to reflect transgender and nonbinary people's gender identities. In January 2022, New York Governor Kathy Hochul directed the prison administrators to let transgender people choose to be housed in a men's or women's facility, and to give access to appropriate medical and mental health care. In 2019, New York DOCCS allowed the first transgender woman to transfer, prior to gender reassignment surgery, from a men's to a women's prison.

Healthcare

Some courts in the US have ruled that hormone replacement therapy is a necessary medical treatment to which transgender prisoners are entitled. In the early 2000s, California Medical Facility, Vacaville, provided this medical treatment for male-to-female prisoners. Additionally, access to psychological counseling and to supportive underclothing like bras can help individuals live as the gender with which they self-identify.

In 1992, UC Irvine researchers published an article detailing medical experiments performed on every trans female inmate in the California state prison system, ending with all subjects being indefinitely taken off hormone therapy. The authors wrote: "withdrawal of therapy was also associated with adverse symptoms in 60 of the 86 transsexuals. Rebound androgenization, hot flashes, moodiness, and irritability or depression were the most frequent complaints." At the time, no right to access gender appropriate care existed in California state prisons.

In June 2019, Layleen Polanco, a Black transgender woman, died of an epileptic seizure in solitary confinement on Rikers Island. Guards had noticed that she was unresponsive but waited 90 minutes to seek help. A year later, it was reported that 17 corrections officers would be disciplined as a result of the incident.

Demographics

In 2011, the National Transgender Discrimination Survey found that 35% of black transgender Americans believe that they have been incarcerated simply due to perceived anti-trans bias, compared to 4% of white transgender respondents. Black transgender people had higher rates of experiences of incarceration in general (47% compared to 12% of white transgender people). It also found that black trans women were sexually assaulted in jail at a rate of 38%, compared to 12% of white trans women prisoners.

Vietnam

In 2015, the National Assembly of Vietnam passed a law which allows transgender people who have done sex reassignment surgery to register under their preferred gender. Further discussion on the treatment of LGBTQ+ people has been initiated in many later meetings of the National Assembly, in which representatives suggested that homosexual and transgender inmates be placed in different places than others. These suggestions were written into law in the 2019 Criminal Code of Vietnam, which went into effect on January 1, 2020. Many attorneys and advocacy groups have praised this as a new step towards ensuring the rights of Vietnamese trans people, while others point out that the law needs amendments that clearly define what these separate areas are like.

According to the new Criminal Code, beside groups like minors, foreigners, and mothers who carry their children of under 36 months into jail along with them, "inmates that are homosexual, transgender or people of unidentified gender can be imprisoned separately." Due to the lack of coverage regarding non-binary people in Vietnam, the phrase "people of unidentified gender" is best understood as trans men or trans women who have not undergone sex reassignment surgery, while "transgender" refers to those who have.

Conjugal visits

A conjugal visit is a scheduled extended visit during which an inmate of a prison is permitted to spend several hours or days in private with visitors, usually family members, in special rooms, trailers or even decorated, apartment-like settings on prison grounds. While the parties may engage in sexual intercourse, in practice an inmate may have several visitors, including children, as the generally recognized basis for permitting such a visit is to preserve family bonds and increase the chances of success for a prisoner's eventual return to life outside prison. Laws on conjugal visits vary widely by country from a total prohibition to very permissive policies. In jurisdictions where there is some form of recognition of same-sex relationships, prisoners may be permitted conjugal visits with a same-sex partner. In the United States, conjugal visits are allowed only in four states: California, Connecticut, New York and Washington.

Same-sex conjugal visitation by country

Argentina
Opposite-sex conjugal visits have long been permitted, but a case in the central province of Córdoba has authorized same-sex conjugal visits as well. The ruling came after an inmate was twice punished with solitary confinement for having sex with his visiting partner in his cell. The inmate brought a lawsuit on the basis of a law that obliges authorities to "guarantee (the availability of) intimate relations for prisoners with their spouses or, alternatively, with their (partners)."
Australia
In Australia, conjugal visits are only permitted in the Australian Capital Territory and Victoria. This includes visits by partners of the same-sex, provided they are not also incarcerated. Conjugal visits of any type are not allowed in New South Wales, Queensland, South Australia, Tasmania, Western Australia and the Northern Territory.
Belgium
Both men and women are entitled to conjugal visitation as heterosexual couples. Belgium's prisons provide facilities where inmates can meet their spouses once a month for a maximum of two uninterrupted hours. There are however circumstances, as they apply to heterosexual couples as well, where these conjugal visits can be revoked.
Brazil
In February 2015 inmates who register their same sex partner have the right to conjugal visitations in all of Brazil's jails. This decision was reached by the National Criminal and Penitentiary Council. The conjugal visit must be guaranteed at least once a month and cannot be prohibited or suspended as a disciplinary measure with the exception of certain cases where violations being restricted are linked to the improper use of conjugal visitations.
Canada
All inmates, with the exception of those on disciplinary restrictions or at risk for family violence, are permitted "Private Family Visits" of up to 72 hours' duration once every two months. Eligible visitors, who may not themselves be prison inmates, are: spouse, or common-law partner of at least six months; children; parents; foster parents; siblings; grandparents; and "persons with whom, in the opinion of the institutional head, the inmate has a close familial bond." Food is provided by the institution but paid by the inmates and visitors, who are also responsible for cleaning the unit after the visit. During a visit, staff members have regular contact with the inmate and visitors.
Caribbean region
Conjugal visits are not permitted in the Caribbean. Marcus Day, adviser to the Association of Caribbean Heads of Corrections and Prison Services has urged the implementation of opposite-sex conjugal visitation for male inmates and the provision of condoms within prisons in an effort to stop the spread of HIV. Day attributes the spread of HIV/AIDS in prisons to "homosexual relationships among otherwise heterosexual men and homosexual rape," situations he said are rife in Caribbean prisons:"Allow men to have the women come and visit them in prison and have a private room where they can make love to each other and the desire to have same-sex relationships will be greatly reduced," claimed Day.
Colombia
On October 11, 2001, the Colombian Supreme Court issued a verdict in favour of the right to same-sex conjugal visits in a case brought by Alba Nelly Montoya, a lesbian in the Risaralda Women's Prison. This was not the first case regarding same-sex conjugal visitation in the country. Marta Alvarez, another lesbian inmate, had been campaigning since 1994 for the same right, and on October 1, 1999 her case became the first ever sexual orientation-related case presented before the Inter-American Commission on Human Rights. In her petition, Alvarez had argued that her rights to personal dignity, integrity, and equality were being infringed upon by the denial to allow her conjugal visits in prison, since the Colombian National Penitentiary and Prison Institute (INPEC) granted conjugal visitation rights in a discriminatory fashion to heterosexual men and women (the latter restricted to visits from husbands only), and denied this right to same-sex couples.
While the Colombian government admitted its failure to grant conjugal visitation to Alvarez constituted "inhuman and discriminatory" treatment, it continued to deny such visits, arguing reasons of security, discipline, and morality. Alvarez was also subjected to retaliatory disciplinary measures, including being transferred to a men's prison, which ceased following a domestic and international protest campaign.
Costa Rica
In August 2008, the Costa Rican Constitutional Tribunal rejected a man's appeal in a lawsuit against prison authorities who stopped his conjugal visits to his male partner, a current inmate, ruling that gay inmates do not have the right to conjugal visits. In 2011, the court rejected this ruling and now allows same-sex conjugal visits.
Israel
Gay prisoners in Israeli Prison System (IPS) are allowed conjugal visits with their partners under the same circumstances as heterosexual prisoners. This policy was revised in July 2013 under Association for Civil Rights in Israel chief legal attorney Dan Yakir challenged the lack of conjugal visits for same sex inmates since 2009.
Mexico
In July 2007 through the efforts of the country's National Human Rights Commission (CDHDF), the Mexico City prison system began allowing same-sex conjugal visits on the basis of a 2003 law which bans discrimination based on sexual orientation. The visitor is not required to be married to the inmate. This policy change applies to all Mexico City Prisons.
Russia
Same-sex long or official visits are prohibited, but short visits for friends can be organised if one is imprisoned in a so-called kolonija-poselenie. Official sex in prison is possible only during the 1–3 day long visit of a registered heterosexual spouse.
United Kingdom
Conjugal visits are not allowed to any prisoner regardless of sexual orientation, but home visits are.
United States
In June 2007, the California Department of Corrections announced it would allow same-sex conjugal visits. The policy was enacted to comply with a 2005 state law requiring state agencies to give the same rights to domestic partners that heterosexual couples receive. The new rules allow for visits only by registered married same sex couples or domestic partners who are not themselves incarcerated. Further, the same sex marriage or domestic partnership must have been established before the prisoner was incarcerated. In April 2011, New York adopted to allow conjugal visits for currently married, or civil-union spouses same-sex partners.

Health care among LGBTQ prisoners by country

United States

Gender-affirming healthcare for transgender and nonbinary people

According to Masen Davis of the Transgender Law Center, LGBTQ people in prisons often face barriers in seeking basic and necessary medical treatment, exacerbated by the fact that prison health care staff are often not aware of or trained on how to address those needs. Incarcerated people in the United States have a constitutional right to healthcare, and incarcerated transgender people can assert legal challenges under the 8th Amendment to access gender-affirming and gender-transition-related care under the framework first articulated in Estelle v. Gamble. The Supreme Court ruled in Farmer v. Brennan (1994) that under the cruel and unusual punishment clause of the Eighth Amendment, prison officials cannot be deliberately indifferent towards blatant abuse directed against transgender prisoners. Eighth Amendment claims can be brought either under 42 U.S.C. § 1983 for state prisoners or under a Bivens action to address deliberate indifference and denial of healthcare in federal prisons.

Defining gender-affirming care

Gender-affirming care can be understood as encompassing both medical (non-surgical), social, and surgical interventions. Under the World Professional Association of Transgender Health (WPATH) "Standards of Care for the Health of Transsexual, Transgender, and Gender Nonconforming People," gender-affirming healthcare is broadly defined as "primary care, gynecologic and urologic care, reproductive options, voice and communication therapy, mental health services (e.g., assessment, counseling, psychotherapy), and hormonal and surgical treatments." Gender-affirming healthcare is widely regarded as a "life-saving" practice" both by physicians and members of the transgender and nonbinary community. Medical scholarship also recognizes that this "treatment is critical to maintain the health and safety of inmates, as without it, transgender prisoners may fall into deeper depression and have greater risk of life-threatening autocastration".

Legal overview of federal court decisions on gender-affirming care

Various courts have addressed the constitutionality of denying transgender people in prison gender-affirming care, including hormone therapy, mental healthcare, gender confirmation surgery, and grooming. Several U.S. Circuit Court of Appeals have held that the prison's duty to treat serious illnesses includes the treatment of gender dysphoria. Other Circuits have held that prison bans on hormonal therapies constitute deliberate indifference in violation of the 8th Amendment. There is some disagreement among Circuits as to whether denial of gender confirmation surgery constitutes deliberate indifference. Some lower courts have affirmed that prohibitions on gender-affirming healthcare are also unconstitutional.

Freeze-frame policies

Freeze-frame policies prevent incarcerated trans people from receiving gender-affirming healthcare, particularly hormone therapy, unless they were already receiving this healthcare prior to their incarceration. Under these policies, trans inmates may not start or expand their treatment while incarcerated. As a result, even a state that is legally bound to offer gender-affirming healthcare to trans inmates may deny that healthcare to someone who was not transitioning before being incarcerated. In other words, freeze-frame policies are much more common than outright bans on hormone therapy for incarcerated people. These policies continue to exist in several U.S. states and have been repealed in others. One obstacle in challenging these policies is that prison policy is determined largely at the state level; as a result, freeze-frame policies have been repealed piecemeal in each state in response to individual lawsuits. Several important cases have challenged freeze-frame policies in the Federal Bureau of Prisons, Georgia, and Missouri. Critics note that these policies rely on the assumption that transness and one's desire or comfort in seeking gender-affirming healthcare is static and fixed.

Ending freeze-frame policies, however, does not guarantee that incarcerated trans people will receive gender-affirming healthcare. Rather, the decisions in each of the cases challenging freeze-frame policies require that prisons conduct individualized assessments of inmates experiencing gender dysphoria. Hormone therapy is not always the treatment offered or deemed necessary following these assessments. In cases challenging these policies, the trans plaintiffs experienced severe mental health crises as a result of being denied care; courts weighed this risk of suicide and self-harm in determining whether hormone therapy was medically necessary for the plaintiffs. Additionally, trans inmates who do receive hormone therapy still do not have control over their healthcare decisions, as prison healthcare officials set dosages and treatment plans for inmates. On the whole, courts ending freeze-frame policies only intervene to ensure that prison policy does not constitute cruel and unusual punishment, leaving a significant gap between constitutionally permissible healthcare and healthcare that enables trans inmates to flourish and act with self-determination.

One of the earliest challenges to a freeze-frame policy came in 2011 in Adams v. Federal Bureau of Prisons. Vanessa Adams, a trans woman incarcerated in a federal prison, was diagnosed while incarcerated with Gender Identity Disorder (GID). Each of her 19 requests for treatment were denied under the BOP's freeze-frame policy. As a result, Adams attempted suicide and self-harm multiple times. In 2009, the National Center for Lesbian Rights, Gay and Lesbian Advocates and Defenders, Florida Institutional Legal Services, and Bingham McCutchen LLP challenged the policy in court. In 2011, the Obama administration settled with Adams. The settlement ended freeze-frame policies in all federal prisons, ensuring that trans inmates would receive individualized assessments and treatment plans for gender dysphoria.

In 2015, Ashley Diamond, a trans woman incarcerated in Georgia, sued the state for failing to provide hormone therapy under a freeze-frame policy and for failing to protect Diamond from sexual assault while incarcerated. She was represented by the Southern Poverty Law Center. Diamond had been undergoing hormone therapy for 17 years prior to her 2012 arrest, but because her intake forms failed to identify her as trans, the Georgia DOC's freeze-frame policy disqualified her from continued treatment. The conditions of her incarceration resulted in multiple self-harm and suicide attempts. Diamond v. Owens was significant because for the first time, the federal government stepped in to comment on states' legal requirements to provide gender-affirming healthcare. The U.S. Department of Justice released a statement in support of Diamond, stating that in Diamond's case, gender dysphoria required medically necessary treatment. Notably, the DOJ did not state unequivocally that prisons must provide hormone therapy. Rather, the DOJ argued that "proscriptive freeze-frame policies are facially unconstitutional under the Eighth Amendment because they do not provide for individualized assessment and treatment." Within a week of the DOJ intervention, Georgia ended its freeze-frame policy, committing instead to individually assess inmates' gender dysphoria and provide treatment accordingly. The court case, during which prison officials used incorrect pronouns in reference to Diamond, continued after this announcement, resulting in the Georgia DOC adopting a sexual assault prevention policy.

Jessica Hicklin, a trans woman from Missouri, was incarcerated at the age of 16 and sentenced to life in prison. At the age of 37, Hicklin challenged the Missouri Department of Corrections freeze-frame policy, claiming that it violated the 8th Amendment cruel and unusual punishment clause; Lambda Legal represented Hicklin in Hicklin v. Precynthe. Hicklin noted that at 16, she did not know what gender dysphoria was or have the resources to begin transitioning. In 2018, a federal court sided with Hicklin and ordered the Missouri DOC to provide Hicklin with gender-affirming healthcare in the form of hormone therapy, as well as other commissary products to help Hicklin socially transition. Hicklin v. Precynthe effectively ended Missouri's freeze-frame policy, giving incarcerated trans people greater access to gender-affirming care across the state.

Canada

On August 31, 2001, the Canadian Human Rights Tribunal concluded that Sections 30 and 31 of the Correctional Service of Canada contained discrimination on the basis of sex and disability in Canadian Human Rights Act after Synthia Kavanagh, a trans woman sentenced for life in 1989 for 2nd-degree murder, was sent to an institution for males. This institution assignment occurred despite the trial judge's recommendation that Synthia, as a trans woman, serve her sentence in a facility for women. Further, Synthia was denied sex reassignment surgery and hormones. The institutional policy, at the time, only facilitated cases which addressed conditions in which, reasonably, the plaintiff would seek sexual reassignment after the period of incarceration. Due to Synthia Kavanagh's life sentence, this was not a foreseeable option. "The decision to discontinue hormones in 1990 seems to have been based on the complainant's life sentence which made her, according to Dr. R. Dickey, apparently ineligible for ultimate reassignment. ... the diagnosis of transsexualism has been clearly established in this case" by expert witness testimony, throughout her trial, "She [had] responded well to feminizing effects of cross-gender hormones and has experienced no significant side effects. As established by legal precedent and confirmed by policy in Canadian and British Columbia Corrections Service, the complainant was entitled to continue her hormone treatment".

In Petitioning the Canadian Human Rights Tribunal, Kavanagh argued that "The Correctional Service of Canada has discriminated and continues to discriminate against me because of my disability and sex (Transsexualism), contrary to Section 5 of the Canadian Human Right Act, by refusing to provide me with necessary medical and surgical treatment." Kavanagh continues to elaborate on her transition prior to imprisonment in this address, stating "since 1981 I have been diagnosed as a transsexual, which means that my gender is female but my sex is male. For 13 years, I was on estrogen hormonal treatment and lived as a woman, in preparation for my sex reassignment surgery to correct my medical disorder. In May 1990, my hormonal treatment was discontinued." After incarceration in a men's facility Kavanagh "repeatedly asked the CSC to arrange for evaluation for sex reassignment surgery, for the surgery to be performed and my consequent transfer to a women's institution." The discontinuation of hormone treatment and rejection of proposed sex reassignment surgery, paired with the continuation of periods of solitude prompted Kavanagh to respond "I believe that the CSC Policy discriminates against transsexuals, as the policy does not recognize the need for the continuation of medical treatment at the onset of incarceration, nor does the policy acknowledge the psychological need to be imprisoned with other members of one's psychological sex at the time of incarceration."

The issue of surgical reassignment has worrying implications for incarcerated transgender people. Individuals serving life sentences or other periods of prolonged incarceration may be less able to "prove" that they live socially as their gender; because this is a requirement to qualify for surgical reassignment, it constitutes a serious institutional barrier for transsexual people attempting to access gender-affirming care.

Hungary

Hungary has compulsory HIV testing, which is part of the Ministry of Health regulations, which requires prostitutes, homosexuals, and prisoners be tested for HIV. When prisoners are found to be HIV positive they are taken to a special unit in Budapest. Units for HIV positive prisoners are staffed with individuals who are trained and who understand the problems of HIV. Specialized treatment of HIV are only available at one hospital in Budapest. HIV treatment for prisoners is paid for by the state-owned National Health Insurance Fund. These prisoners have their own cells with their own showers, a community room with games, and a social worker available to them. Post test counseling is also provided.

LGBT youth prisoners in the United States

According to some studies, LGBT youth are particularly at risk for arrest and detention. Jody Marksamer, Shannan Wilber, and Katayoon Majd, writing on behalf of the Equity Project, a collaboration between Legal Services for Children, the National Center for Lesbian Rights, and the National Juvenile Defender Center, say that LGBT youth are over represented in the populations of youth who are at risk of arrest and of those who are confined in juvenile justice facilities in the United States.

Many LGBT youth often experience being cast aside from their families and hostile environments while at school. The school system fails many LGBT students through their zero-tolerance policy which is meant to protect them but often results in LGBT students being arrested or given harsh disciplinary action. According to "Messy, Butch, and Queer: LGBTQ Youth and the School-to-Prison Pipeline", LGBT youth are often blamed for the harassment they receive despite the fact that they are being targeted solely upon their sexual orientation or the way the LGBT students present themselves.

Queer youth are also socially and economically vulnerable, especially in regards to high rates of homelessness. This vulnerability can lead to illegal behavior, and also over policing when homeless, creating an over representation of LGBT youth in prisons. See Homelessness among LGBT youth in the United States, and LGBT youth vulnerability.

A brief by the Center for American Progress found that each year approximately 300,000 gay, trans, and gender nonconforming youth are arrested or detained each year, 60% of whom are Black or Hispanic. These queer youth make up 13–15 percent of the juvenile incarceration system, compared to their overall population of 5–7 percent. Similar to how transgender adults are often placed into solitary confinement, allegedly for their own protection, these youth are "protected" in the same way. Often, however, it is because they are seen as sexual predators rather than potential victims. Courts also commonly assign queer youth to sex offender treatment programs even when convicted of a non-sexual crime. "As 12% of adjudicated youth in juvenile facilities reported experiencing sexual abuse in 2009" according to a report from the Juvenile Law Center.

Physical and sexual abuse

According to Amnesty International, globally, LGBT prisoners and those perceived to be LGBT, are at risk of torture, ill-treatment and violence from other inmates as well as prison officials. Amnesty International cites numerous cases internationally where LGBT inmates are known to have been abused or murdered by prison officials or fellow inmates.

A 2007 report by the Center for Evidence-Based Corrections at the University of California, Irvine found that 59% of a purposive sample of transgender people in one prison in California had been sexually assaulted while incarcerated, compared to 4.4% of a randomized sample of male prisoners from six California prisons. Transgender women in male prisons also deal with the risk of forced prostitution by both prison staff and other prisoners. Forced prostitution can occur when a correction officer brings a transgender woman to the cell of a male inmate and locks them in so that the male inmate can rape her. The male inmate will then pay the correction officer in some way and sometimes the correction officer will give the woman a portion of the payment.

"[P]risoners fitting any part of the following description are more likely to be targeted: young, small in size, physically weak, gay, first offender, possessing "feminine" characteristics such as long hair or a high voice; being unassertive, unaggressive, shy, intellectual, not street-smart, or "passive"; or having been convicted of a sexual offense against a minor. Prisoners with any one of these characteristics typically face an increased risk of sexual abuse, while prisoners with several overlapping characteristics are much more likely than other prisoners to be targeted for abuse."

In the United States

Gay and bisexual men are often assumed to be responsible for the preponderance of sexual assaults perpetrated in prisons as has been reflected in various American judicial decisions. For example, in Cole v. Flick[nb 2] the court upheld the right of prisons to limit the length of inmates' hair, claiming that allowing them to wear long hair could lead to an increase in attacks by "predatory homosexuals". In Roland v. Johnson, the court described "gangs of homosexual predators". And Ashann-Ra v. Virginia contains references to "inmates known to be predatory homosexuals [stalking] other inmates in the showers".

According to a study by Human Rights Watch, however, "The myth of the 'homosexual predator' is groundless. Perpetrators of rape typically view themselves as heterosexual and, outside of the prison environment, prefer to engage in heterosexual activity. Although gay inmates are much more likely than other inmates to be victimized in prison, they are not likely to be perpetrators of sexual abuse." (see also situational homosexuality)

A related problem is that there is a tendency, among both prison officials and prisoners, to view victimization as proof of homosexuality: "The fact of submitting to rape—even violent, forcible rape—redefines [a prisoner] as 'a punk, sissy, queer.'" Officials sometimes take the view all sex involving a gay prisoner is necessarily consensual, meaning that victims known or perceived to be gay may not receive necessary medical treatment, protection, and legal recourse, and perpetrators may go unpunished and remain able to perpetrate abuse on their victims.

According to Andrea Cavanaugh Kern, a spokesperson for Stop Prisoner Rape, the combination of high rates of sexual assault against gay prisoners and high rates of HIV infection in the prison population is "a life-or-death issue for the LGBT community".

While much of the data regards male prisoners, according to Amnesty International, "perceived or actual sexual orientation has been found to be one of four categories that make a female prisoner a more likely target for sexual abuse". It wasn't until 2003 that PREA (Prison Rape Elimination Act) was enacted by United States Congress to aid in the prevention of sexual abuse and misconduct.

V-coding

A 2018 report from the Indiana Maurer University School of Law found that it was common for trans women placed in men's prisons to be assigned to cells with aggressive cisgender male cellmates as both a reward and a means of placation for said cellmates, so as to maintain social control and to, as one inmate described it, "keep the violence rate down". Trans women used in this manner are often raped daily. This process is known as "V-coding", and has been described as so common that it is effectively "a central part of a trans woman's sentence".

The report also found it common for correctional officers to publicly strip search trans women inmates, before putting their bodies on display for not only the other correctional officers, but for the other prisoners. Trans women in this situation are sometimes made to dance, present, or masturbate at the CO's discretion.

The prisoners serving as customers for these women are informally referred to as "husbands". Trans women who physically resist the customer's advances are often criminally charged with assault and placed in solitary confinement, the assault charge then being used to extend the woman's prison stay and deny her parole.

Colombia

In 2019, la Defensoría del Pueblo identified 285 cases of violence and discrimination against LGBTI prisoners. Over a third of these victims were transgender. One-eighth were Venezuelan.

Segregation

For their own safety, LGBT people in prison are sometimes placed in administrative segregation or protective custody. Although homosexuality is "generally regarded as a factor supporting an inmate's claim to protective custody", homophobia among prison officials and a misperception among many guards that "when a gay inmate has sex with another man it is somehow by definition consensual" mean that access to such custody is not always easy or available.

Another problem is that protective and disciplinary custody are often the same, which means that prisoners in "protective housing" are often held with the most violent inmates in highly restrictive and isolated settings—sometimes in more or less permanent lockdown or solitary confinement—that prevent them from participating in drug treatment, education and job-training programs, from having contact with other prisoners or outside visitors, or from enjoying privileges such as the right to watch television, listen to the radio, or even to leave their cells. The degree of safety that protective custody provides depends on the facilities. Protective custody can provide a secure environment that is free from violence by other prisoners or it can isolate prisoners, and position them with a higher risk of violence by a correctional officer. Although the protective custody can offer some level of protection, the harmful physical and psychological impacts of isolation show that it is an unwanted alternative to assignment in the general population.

In other cases, institutions may have special areas (known by such nicknames as the "queerentine", "gay tank", "queen tank", or "softie tank") for housing vulnerable inmates such as LGBT people, elderly or disabled prisoners, or informers.

LGBT Prison Segregation in the United States

In San Francisco, for example, transgender inmates are automatically segregated from other prisoners. Nevertheless, according to Eileen Hirst, San Francisco Sheriff's Chief of Staff, being gay is not in itself enough to justify a request for protective housing: inmates requesting such housing must demonstrate that they are vulnerable.

For financial or other reasons segregated housing is not always available. For instance at Rikers Island, New York City's largest jail, the segregated unit for LGBT prisoners, known as "gay housing", was closed in December 2005 citing a need to improve security. The unit had opened in the 1970s due to concerns about abuse of LGBT prisoners in pretrial detention. The New York City Department of Corrections' widely criticised plan was to restructure the classification of prisoners and create a new protective custody system which would include 23-hour-per-day lockdown (identical to that mandated for disciplinary reasons) or moving vulnerable inmates to other facilities. Whereas formerly all that was required was a declaration of homosexuality or the appearance of being transgender, inmates wanting protective custody would now be required to request it in a special hearing.

Solitary confinement

Solitary confinement has become the prison system's preferred method to protect transgender inmates from other prisoners in cases involving sexual assault, harassment and physical violence. Advocates for transgender prisoners argue that this method only increases the harassment they receive from officers and various other staff members as reported by Injustice at Every Turn.

Solitary Confinement in the United States

In the report, 44% of transgender male respondents and 40% of transgender women respondents who were imprisoned reported being harassed by officers and/or other staff members of the prison system. While in solitary confinement, transgender individuals are less likely to receive medical care.

Out of the respondents in the same report 12% of transgender individuals surveyed reported being denied routine non-transition related healthcare and 17% reported being denied hormone treatment. The number was disproportionately higher when transgender people of color reported lack of transition health care and hormone treatment with American Indians reporting 36% denial and Black and/or African American reporting a 30% denial rate. The use of solitary confinement also lessens transgender inmate's access to programs and work assignments where they may be able to lessen their sentences, enter rehabilitation programs, or earn money to buy basic products such as soap and also lessens their chances to obtain parole or conditional release.

Solitary confinement has also shown to affect the mental health of transgender prisoners. With the report of filed by Injustice at Every Turn, 41% of respondents reported attempted suicide. With transgender people of color, 56% of American Indian and 54% of multiracial individuals reported attempted suicide. The report also links the over-use of solitary confinement as a factor in the high rate of suicide attempts by transgender people of color within the prison system.

In addition to the conditions themselves amounting to torture, solitary confinement usually restricts a person's access to education, work, and program opportunities. While mental health is a key priority and emphasis for inmates subjected to solitary confinement, there are other discriminatory disadvantages that come with it as well. For example, education and work programs are often essential prerequisites to achieving good time and parole. This means that many LGBT people, who are more likely to be placed in solitary confinement, are also less likely to be paroled or released early, forcing them to serve out their maximum sentences. Activists argue that members of the LGBT community should have equal access to prison programs and services, a right protected and provided for under the Fourteenth Amendment of the U.S. Constitution.

According to Title IX of the Education Amendments, discrimination on the basis of sex is illegal. Many education programs in prisons, jails, and juvenile detention centers are funded by the Federal government and those who take funding from the government must adhere to the full tenets of these amendments. Title IX extends to protect inmates who are denied access to prison programs and resources because of their gender identity or sexual orientation. The Fourteenth Amendment asserts that all inmates should have equal access to libraries, educational programs, the internet, and corresponding resources.

Solitary Confinement in Canada

In cases where the incarcerated are assigned to prisons based on sex, rather than their gender-identity, complete segregation is often seen as the only viable way for ensuring safety. In the case of Synthia Kavanagh, she was assigned to a male institution despite explicit recommendations from the trial judge. As a result, Kavanagh was "placed in segregation over extended periods of her incarceration for the purpose of protection from self-harm or abuse by others. Segregation for prolonged periods is not only inhuman but [is additionally] unconducive to any prospect of stabilization or rehabilitation."

Support for LGBT people in prison

As a result of the rise of awareness of LGBT persons in prisons, many organizations have developed specifically to support LGBT people in the prison system. These organizations address the various needs surrounding specific issues that LGBT persons in the prison system face. Some organizations also support family members of LGBTQ inmates.

Black and Pink is an American organization that is composed of "LGBTQ prisoners and 'free world' allies" who focus on prison abolishment movement and support LGBTQ prison inmates and their families. The organization offers various services such as court accompaniment, a pen pal program, workshops and training, and support for LGBTQ persons who are experiencing sexual violence, harassment, or lack of health care.

LGBT Books to Prisoners is donation-funded, volunteer-run, non-profit support group based in Madison, WI. It sends books and other educational materials, free of charge, to incarcerated LGBT people across the United States. Since its founding in 2008, the organization has sent materials to almost 9,000 people.

The Prison Activists Resource Center also provides information for organizations that are dedicated solely for LGBT Prisoners, such as Hearts on a Wire which is a Pennsylvania-based organization focused on helping Transgender individuals. Other listed resources include GLBTQ Advocates and Defenders (GLAD) and LGBT Books to Prisoners. These sources either provide links for possible legal assistance, or provide materials in an attempt to make the prison experience more bearable.

Testosterone

From Wikipedia, the free encyclopedia

Testosterone is the primary male sex hormone and anabolic steroid in males. In humans, testosterone plays a key role in the development of male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. It is associated with increased aggression, violence, and criminal behavior, sex drive, the inclination to impress partners and other courting behaviors. In addition, testosterone in both sexes is involved in health and well-being, where it has a significant effect on overall mood, cognition, social and sexual behaviour, metabolism and energy output, the cardiovascular system, and in the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty, accumulation of adipose fat tissue within the body, anxiety and depression, sexual performance issues, and bone loss.

Excessive levels of testosterone in men may be associated with hyperandrogenism, higher risk of heart failure, increased mortality in men with prostate cancer, male pattern baldness, criminality, impulsivity, and hypersexuality.

Testosterone is a steroid from the androstane class containing a ketone and a hydroxyl group at positions three and seventeen respectively. It is biosynthesized in several steps from cholesterol and is converted in the liver to inactive metabolites. It exerts its action through binding to and activation of the androgen receptor. In humans and most other vertebrates, testosterone is secreted primarily by the testicles of males and, to a lesser extent, the ovaries of females. On average, in adult males, levels of testosterone are about seven to eight times as great as in adult females. As the metabolism of testosterone in males is more pronounced, the daily production is about 20 times greater in men. Females are also more sensitive to the hormone.

In addition to its role as a natural hormone, testosterone is used as a medication to treat hypogonadism, breast cancer, and gender dysphoria. Since testosterone levels decrease as men age, testosterone is sometimes used in older men to counteract this deficiency. It is also used illicitly to enhance physique and performance, for instance in athletes. The World Anti-Doping Agency lists it as S1 Anabolic agent substance "prohibited at all times".

Biological effects

In general, androgens such as testosterone promote protein synthesis and thus growth of tissues with androgen receptors. Recently, Gharahdaghi et al. reported that endogenous and exogenous testosterone play a permissive role in adaptation to exercise training in younger and older men. Testosterone can be described as having virilising and anabolic effects (though these categorical descriptions are somewhat arbitrary, as there is a great deal of mutual overlap between them).

Testosterone effects can also be classified by the age of usual occurrence. For postnatal effects in both males and females, these are mostly dependent on the levels and duration of circulating free testosterone.

Before birth

Effects before birth are divided into two categories, classified in relation to the stages of development.

The first period occurs between 4 and 6 weeks of the gestation. Examples include genital virilisation such as midline fusion, phallic urethra, scrotal thinning and rugation, and phallic enlargement; although the role of testosterone is far smaller than that of dihydrotestosterone. There is also development of the prostate gland and seminal vesicles.

During the second trimester, androgen level is associated with sex formation. Specifically, testosterone, along with anti-Müllerian hormone (AMH) promote growth of the Wolffian duct and degeneration of the Müllerian duct respectively. This period affects the femininization or masculinization of the fetus and can be a better predictor of feminine or masculine behaviours such as sex typed behaviour than an adult's own levels. Prenatal androgens apparently influence interests and engagement in gendered activities and have moderate effects on spatial abilities. Among women with congenital adrenal hyperplasia, a male-typical play in childhood correlated with reduced satisfaction with the female gender and reduced heterosexual interest in adulthood.

Early infancy

Early infancy androgen effects are the least understood. In the first weeks of life for male infants, testosterone levels rise. The levels remain in a pubertal range for a few months, but usually reach the barely detectable levels of childhood by 4–7 months of age. The function of this rise in humans is unknown. It has been theorized that brain masculinization is occurring since no significant changes have been identified in other parts of the body. The male brain is masculinized by the aromatization of testosterone into estradiol, which crosses the blood–brain barrier and enters the male brain, whereas female fetuses have α-fetoprotein, which binds the estrogen so that female brains are not affected.

Before puberty

Before puberty, effects of rising androgen levels occur in both boys and girls. These include adult-type body odor, increased oiliness of skin and hair, acne, pubarche (appearance of pubic hair), axillary hair (armpit hair), growth spurt, accelerated bone maturation, and facial hair.

Pubertal

Pubertal effects begin to occur when androgen has been higher than normal adult female levels for months or years. In males, these are usual late pubertal effects, and occur in women after prolonged periods of heightened levels of free testosterone in the blood. The effects include:

Adult

Testosterone is necessary for normal sperm development. It activates genes in Sertoli cells, which promote differentiation of spermatogonia. It regulates acute HPA (hypothalamic–pituitary–adrenal axis) response under dominance challenge. Androgens including testosterone enhance muscle growth. Testosterone also regulates the population of thromboxane A2 receptors on megakaryocytes and platelets and hence platelet aggregation in humans.

Adult testosterone effects are more clearly demonstrable in males than in females, but are likely important to both sexes. Some of these effects may decline as testosterone levels might decrease in the later decades of adult life.

Health risks

Testosterone does not appear to increase the risk of developing prostate cancer. In people who have undergone testosterone deprivation therapy, testosterone increases beyond the castrate level have been shown to increase the rate of spread of an existing prostate cancer.

Conflicting results have been obtained concerning the importance of testosterone in maintaining cardiovascular health. Nevertheless, maintaining normal testosterone levels in elderly men has been shown to improve many parameters that are thought to reduce cardiovascular disease risk, such as increased lean body mass, decreased visceral fat mass, decreased total cholesterol, and glycemic control.

High androgen levels are associated with menstrual cycle irregularities in both clinical populations and healthy women.

Sexual arousal

Testosterone levels follow a nycthemeral rhythm that peaks early each day, regardless of sexual activity.

There are positive correlations between positive orgasm experience in women and testosterone levels where relaxation was a key perception of the experience. There is no correlation between testosterone and men's perceptions of their orgasm experience, and also no correlation between higher testosterone levels and greater sexual assertiveness in either sex.

Sexual arousal and masturbation in women produce small increases in testosterone concentrations. The plasma levels of various steroids significantly increase after masturbation in men and the testosterone levels correlate to those levels.

Mammalian studies

Studies conducted in rats have indicated that their degree of sexual arousal is sensitive to reductions in testosterone. When testosterone-deprived rats were given medium levels of testosterone, their sexual behaviours (copulation, partner preference, etc.) resumed, but not when given low amounts of the same hormone. Therefore, these mammals may provide a model for studying clinical populations among humans with sexual arousal deficits such as hypoactive sexual desire disorder.

Every mammalian species examined demonstrated a marked increase in a male's testosterone level upon encountering a novel female. The reflexive testosterone increases in male mice is related to the male's initial level of sexual arousal.

In non-human primates, it may be that testosterone in puberty stimulates sexual arousal, which allows the primate to increasingly seek out sexual experiences with females and thus creates a sexual preference for females. Some research has also indicated that if testosterone is eliminated in an adult male human or other adult male primate's system, its sexual motivation decreases, but there is no corresponding decrease in ability to engage in sexual activity (mounting, ejaculating, etc.).

In accordance with sperm competition theory, testosterone levels are shown to increase as a response to previously neutral stimuli when conditioned to become sexual in male rats. This reaction engages penile reflexes (such as erection and ejaculation) that aid in sperm competition when more than one male is present in mating encounters, allowing for more production of successful sperm and a higher chance of reproduction.

Males

In men, higher levels of testosterone are associated with periods of sexual activity.

Men who watch a sexually explicit movie have an average increase of 35% in testosterone, peaking at 60–90 minutes after the end of the film, but no increase is seen in men who watch sexually neutral films. Men who watch sexually explicit films also report increased motivation, competitiveness, and decreased exhaustion. A link has also been found between relaxation following sexual arousal and testosterone levels.

Men's levels of testosterone change depending on whether they are exposed to an ovulating or nonovulating woman's body odour. Men who are exposed to scents of ovulating women maintained a stable testosterone level that was higher than the testosterone level of men exposed to nonovulation cues. Men are heavily aware of hormone cycles in women. This may be linked to the ovulatory shift hypothesis, where males are adapted to respond to the ovulation cycles of females by sensing when they are most fertile and whereby females look for preferred male mates when they are the most fertile; both actions may be driven by hormones.

Females

Androgens may modulate the physiology of vaginal tissue and contribute to female genital sexual arousal. Women's level of testosterone is higher when measured pre-intercourse vs. pre-cuddling, as well as post-intercourse vs. post-cuddling. There is a time lag effect when testosterone is administered, on genital arousal in women. In addition, a continuous increase in vaginal sexual arousal may result in higher genital sensations and sexual appetitive behaviors.

When females have a higher baseline level of testosterone, they have higher increases in sexual arousal levels but smaller increases in testosterone, indicating a ceiling effect on testosterone levels in females. Sexual thoughts also change the level of testosterone but not the level of cortisol in the female body, and hormonal contraceptives may affect the variation in testosterone response to sexual thoughts.

Testosterone may prove to be an effective treatment in female sexual arousal disorders, and is available as a dermal patch. There is no FDA-approved androgen preparation for the treatment of androgen insufficiency; however, it has been used as an off-label use to treat low libido and sexual dysfunction in older women. Testosterone may be a treatment for postmenopausal women as long as they are effectively estrogenized.

In females, testosterone levels peak at about 17-18 years of age.

Romantic relationships

Falling in love has been linked with decreases in men's testosterone levels while mixed changes are reported for women's testosterone levels. There has been speculation that these changes in testosterone result in the temporary reduction of differences in behavior between the sexes. However, the testosterone changes observed do not seem to be maintained as relationships develop over time.

Men who produce less testosterone are more likely to be in a relationship or married, and men who produce more testosterone are more likely to divorce. Marriage or commitment could cause a decrease in testosterone levels. Single men who have not had relationship experience have lower testosterone levels than single men with experience. It is suggested that these single men with prior experience are in a more competitive state than their non-experienced counterparts. Married men who engage in bond-maintenance activities such as spending the day with their spouse and/or child have no different testosterone levels compared to times when they do not engage in such activities. Collectively, these results suggest that the presence of competitive activities rather than bond-maintenance activities are more relevant to changes in testosterone levels.

Men who produce more testosterone are more likely to engage in extramarital sex. Testosterone levels do not rely on physical presence of a partner; testosterone levels of men engaging in same-city and long-distance relationships are similar. Physical presence may be required for women who are in relationships for the testosterone–partner interaction, where same-city partnered women have lower testosterone levels than long-distance partnered women.

Fatherhood

Fatherhood decreases testosterone levels in men, suggesting that the emotions and behaviour tied to paternal care decrease testosterone levels. In humans and other species that utilize allomaternal care, paternal investment in offspring is beneficial to said offspring's survival because it allows the two parents to raise multiple children simultaneously. This increases the reproductive fitness of the parents because their offspring are more likely to survive and reproduce. Paternal care increases offspring survival due to increased access to higher quality food and reduced physical and immunological threats. This is particularly beneficial for humans since offspring are dependent on parents for extended periods of time and mothers have relatively short inter-birth intervals.

While the extent of paternal care varies between cultures, higher investment in direct child care has been seen to be correlated with lower average testosterone levels as well as temporary fluctuations. For instance, fluctuation in testosterone levels when a child is in distress has been found to be indicative of fathering styles. If a father's testosterone levels decrease in response to hearing their baby cry, it is an indication of empathizing with the baby. This is associated with increased nurturing behavior and better outcomes for the infant.

Motivation

Testosterone levels play a major role in risk-taking during financial decisions. Higher testosterone levels in men reduce the risk of becoming or staying unemployed. Increased testosterone in men increases their generosity, primarily to attract a potential mate.

Aggression and criminality

Most studies support a link between adult criminality and testosterone. Nearly all studies of juvenile delinquency and testosterone are not significant. Most studies have also found testosterone to be associated with behaviors or personality traits linked with antisocial behavior and alcoholism. Many studies have also been done on the relationship between more general aggressive behavior and feelings and testosterone. About half the studies have found a relationship and about half no relationship. Studies have also found that testosterone facilitates aggression by modulating vasopressin receptors in the hypothalamus.

There are two theories on the role of testosterone in aggression and competition. The first one is the challenge hypothesis which states that testosterone would increase during puberty, thus facilitating reproductive and competitive behavior which would include aggression. It is therefore the challenge of competition among males of the species that facilitates aggression and violence. Studies conducted have found direct correlation between testosterone and dominance, especially among the most violent criminals in prison who had the highest testosterone levels. The same research also found fathers (those outside competitive environments) had the lowest testosterone levels compared to other males.[90]

The second theory is similar and is known as "evolutionary neuroandrogenic (ENA) theory of male aggression". Testosterone and other androgens have evolved to masculinize a brain in order to be competitive even to the point of risking harm to the person and others. By doing so, individuals with masculinized brains as a result of pre-natal and adult life testosterone and androgens enhance their resource acquiring abilities in order to survive, attract and copulate with mates as much as possible. The masculinization of the brain is not just mediated by testosterone levels at the adult stage, but also testosterone exposure in the womb as a fetus. Higher pre-natal testosterone indicated by a low digit ratio as well as adult testosterone levels increased risk of fouls or aggression among male players in a soccer game. Studies have also found higher pre-natal testosterone or lower digit ratio to be correlated with higher aggression in males.

The rise in testosterone levels during competition predicted aggression in males but not in females. Subjects who interacted with hand guns and an experimental game showed rise in testosterone and aggression. Natural selection might have evolved males to be more sensitive to competitive and status challenge situations and that the interacting roles of testosterone are the essential ingredient for aggressive behaviour in these situations. Testosterone mediates attraction to cruel and violent cues in men by promoting extended viewing of violent stimuli. Testosterone-specific structural brain characteristic can predict aggressive behaviour in individuals.

Testosterone might encourage fair behavior. For one study, subjects took part in a behavioral experiment where the distribution of a real amount of money was decided. The rules allowed both fair and unfair offers. The negotiating partner could subsequently accept or decline the offer. The fairer the offer, the less probable a refusal by the negotiating partner. If no agreement was reached, neither party earned anything. Test subjects with an artificially enhanced testosterone level generally made better, fairer offers than those who received placebos, thus reducing the risk of a rejection of their offer to a minimum. Two later studies have empirically confirmed these results. However men with high testosterone were significantly 27% less generous in an ultimatum game. The Annual NY Academy of Sciences has also found anabolic steroid use (which increases testosterone) to be higher in teenagers, and this was associated with increased violence. Studies have also found administered testosterone to increase verbal aggression and anger in some participants.

A few studies indicate that the testosterone derivative estradiol (one form of estrogen) might play an important role in male aggression. Estradiol is known to correlate with aggression in male mice. Moreover, the conversion of testosterone to estradiol regulates male aggression in sparrows during breeding season. Rats who were given anabolic steroids that increase testosterone were also more physically aggressive to provocation as a result of "threat sensitivity".

The relationship between testosterone and aggression may also function indirectly, as it has been proposed that testosterone does not amplify tendencies towards aggression but rather amplifies whatever tendencies will allow an individual to maintain social status when challenged. In most animals, aggression is the means of maintaining social status. However, humans have multiple ways of obtaining social status. This could explain why some studies find a link between testosterone and pro-social behaviour if pro-social behaviour is rewarded with social status. Thus the link between testosterone and aggression and violence is due to these being rewarded with social status. The relationship may also be one of a "permissive effect" whereby testosterone does elevate aggression levels but only in the sense of allowing average aggression levels to be maintained; chemically or physically castrating the individual will reduce aggression levels (though it will not eliminate them) but the individual only needs a small-level of pre-castration testosterone to have aggression levels to return to normal, which they will remain at even if additional testosterone is added. Testosterone may also simply exaggerate or amplify existing aggression; for example, chimpanzees who receive testosterone increases become more aggressive to chimps lower than them in the social hierarchy but will still be submissive to chimps higher than them. Testosterone thus does not make the chimpanzee indiscriminately aggressive but instead amplifies his pre-existing aggression towards lower-ranked chimps.

In humans, testosterone appears more to promote status-seeking and social dominance than simply increasing physical aggression. When controlling for the effects of belief in having received testosterone, women who have received testosterone make fairer offers than women who have not received testosterone.

Brain

The brain is also affected by this sexual differentiation; the enzyme aromatase converts testosterone into estradiol that is responsible for masculinization of the brain in male mice. In humans, masculinization of the fetal brain appears, by observation of gender preference in patients with congenital disorders of androgen formation or androgen receptor function, to be associated with functional androgen receptors.

There are some differences between a male and female brain that may be due to different testosterone levels, one of them being size: the male human brain is, on average, larger.

No immediate short term effects on mood or behavior were found from the administration of supraphysiologic doses of testosterone for 10 weeks on 43 healthy men. A correlation between testosterone and risk tolerance in career choice exists among women.

Attention, memory, and spatial ability are key cognitive functions affected by testosterone in humans. Preliminary evidence suggests that low testosterone levels may be a risk factor for cognitive decline and possibly for dementia of the Alzheimer's type, a key argument in life extension medicine for the use of testosterone in anti-aging therapies. Much of the literature, however, suggests a curvilinear or even quadratic relationship between spatial performance and circulating testosterone, where both hypo- and hypersecretion (deficient- and excessive-secretion) of circulating androgens have negative effects on cognition.

Immune system and inflammation

Testosterone deficiency is associated with an increased risk of metabolic syndrome, cardiovascular disease and mortality, which are also sequelae of chronic inflammation. Testosterone plasma concentration inversely correlates to multiple biomarkers of inflammation including CRP, interleukin 1 beta, interleukin 6, TNF alpha and endotoxin concentration, as well as leukocyte count. As demonstrated by a meta-analysis, substitution therapy with testosterone results in a significant reduction of inflammatory markers. These effects are mediated by different mechanisms with synergistic action. In androgen-deficient men with concomitant autoimmune thyroiditis, substitution therapy with testosterone leads to a decrease in thyroid autoantibody titres and an increase in thyroid's secretory capacity (SPINA-GT).

Medical use

Testosterone is used as a medication for the treatment of male hypogonadism, gender dysphoria, and certain types of breast cancer. This is known as hormone replacement therapy (HRT) or testosterone replacement therapy (TRT), which maintains serum testosterone levels in the normal range. Decline of testosterone production with age has led to interest in androgen replacement therapy. It is unclear if the use of testosterone for low levels due to aging is beneficial or harmful.

Testosterone is included in the World Health Organization's list of essential medicines, which are the most important medications needed in a basic health system. It is available as a generic medication. It can be administered as a cream or transdermal patch that is applied to the skin, by injection into a muscle, as a tablet that is placed in the cheek, or by ingestion.

Common side effects from testosterone medication include acne, swelling, and breast enlargement in males. Serious side effects may include liver toxicity, heart disease, and behavioral changes. Women and children who are exposed may develop virilization. It is recommended that individuals with prostate cancer not use the medication. It can cause harm if used during pregnancy or breastfeeding.

2020 guidelines from the American College of Physicians support the discussion of testosterone treatment in adult men with age-related low levels of testosterone who have sexual dysfunction. They recommend yearly evaluation regarding possible improvement and, if none, to discontinue testosterone; physicians should consider intramuscular treatments, rather than transdermal treatments, due to costs and since the effectiveness and harm of either method is similar. Testosterone treatment for reasons other than possible improvement of sexual dysfunction may not be recommended.

Biological activity

Free testosterone

Lipophilic hormones (soluble in lipids but not in water), such as steroid hormones, including testosterone, are transported in water-based blood plasma through specific and non-specific proteins. Specific proteins include sex hormone-binding globulin (SHBG), which binds testosterone, dihydrotestosterone, estradiol, and other sex steroids. Non-specific binding proteins include albumin and lipoprotein. The part of the total hormone concentration that is not bound to its respective specific carrier protein is the free part. As a result, testosterone which is not bound to SHBG is called free testosterone. It seems that only the free amount of testosterone can bind to an androgenic receptor, which means they have biological activity.

Steroid hormone activity

The effects of testosterone in humans and other vertebrates occur by way of multiple mechanisms: by activation of the androgen receptor (directly or as dihydrotestosterone), and by conversion to estradiol and activation of certain estrogen receptors. Androgens such as testosterone have also been found to bind to and activate membrane androgen receptors.

Free testosterone (T) is transported into the cytoplasm of target tissue cells, where it can bind to the androgen receptor, or can be reduced to 5α-dihydrotestosterone (DHT) by the cytoplasmic enzyme 5α-reductase. DHT binds to the same androgen receptor even more strongly than testosterone, so that its androgenic potency is about 5 times that of T. The T-receptor or DHT-receptor complex undergoes a structural change that allows it to move into the cell nucleus and bind directly to specific nucleotide sequences of the chromosomal DNA. The areas of binding are called hormone response elements (HREs), and influence transcriptional activity of certain genes, producing the androgen effects.

Androgen receptors occur in many different vertebrate body system tissues, and both males and females respond similarly to similar levels. Greatly differing amounts of testosterone prenatally, at puberty, and throughout life account for a share of biological differences between males and females.

The bones and the brain are two important tissues in humans where the primary effect of testosterone is by way of aromatization to estradiol. In the bones, estradiol accelerates ossification of cartilage into bone, leading to closure of the epiphyses and conclusion of growth. In the central nervous system, testosterone is aromatized to estradiol. Estradiol rather than testosterone serves as the most important feedback signal to the hypothalamus (especially affecting LH secretion). In many mammals, prenatal or perinatal "masculinization" of the sexually dimorphic areas of the brain by estradiol derived from testosterone programs later male sexual behavior.

Neurosteroid activity

Testosterone, via its active metabolite 3α-androstanediol, is a potent positive allosteric modulator of the GABAA receptor.

Testosterone has been found to act as an antagonist of the TrkA and p75NTR, receptors for the neurotrophin nerve growth factor (NGF), with high affinity (around 5 nM). In contrast to testosterone, DHEA and DHEA sulfate have been found to act as high-affinity agonists of these receptors.

Testosterone is an antagonist of the sigma-1 receptor (Ki = 1,014 or 201 nM). However, the concentrations of testosterone required for binding the receptor are far above even total circulating concentrations of testosterone in adult males (which range between 10 and 35 nM).

Biochemistry

Human steroidogenesis, showing testosterone near bottom

Biosynthesis

Like other steroid hormones, testosterone is derived from cholesterol (see figure). The first step in the biosynthesis involves the oxidative cleavage of the side-chain of cholesterol by cholesterol side-chain cleavage enzyme (P450scc, CYP11A1), a mitochondrial cytochrome P450 oxidase with the loss of six carbon atoms to give pregnenolone. In the next step, two additional carbon atoms are removed by the CYP17A1 (17α-hydroxylase/17,20-lyase) enzyme in the endoplasmic reticulum to yield a variety of C19 steroids. In addition, the 3β-hydroxyl group is oxidized by 3β-hydroxysteroid dehydrogenase to produce androstenedione. In the final and rate limiting step, the C17 keto group androstenedione is reduced by 17β-hydroxysteroid dehydrogenase to yield testosterone.

The largest amounts of testosterone (>95%) are produced by the testes in men, while the adrenal glands account for most of the remainder. Testosterone is also synthesized in far smaller total quantities in women by the adrenal glands, thecal cells of the ovaries, and, during pregnancy, by the placenta. In the testes, testosterone is produced by the Leydig cells. The male generative glands also contain Sertoli cells, which require testosterone for spermatogenesis. Like most hormones, testosterone is supplied to target tissues in the blood where much of it is transported bound to a specific plasma protein, sex hormone-binding globulin (SHBG).

Regulation

Hypothalamic–pituitary–testicular axis

In males, testosterone is synthesized primarily in Leydig cells. The number of Leydig cells in turn is regulated by luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In addition, the amount of testosterone produced by existing Leydig cells is under the control of LH, which regulates the expression of 17β-hydroxysteroid dehydrogenase.

The amount of testosterone synthesized is regulated by the hypothalamic–pituitary–testicular axis (see figure to the right). When testosterone levels are low, gonadotropin-releasing hormone (GnRH) is released by the hypothalamus, which in turn stimulates the pituitary gland to release FSH and LH. These latter two hormones stimulate the testis to synthesize testosterone. Finally, increasing levels of testosterone through a negative feedback loop act on the hypothalamus and pituitary to inhibit the release of GnRH and FSH/LH, respectively.

Factors affecting testosterone levels may include:

  • Age: Testosterone levels gradually reduce as men age. This effect is sometimes referred to as andropause or late-onset hypogonadism.
  • Exercise: Resistance training increases testosterone levels acutely, however, in older men, that increase can be avoided by protein ingestion. Endurance training in men may lead to lower testosterone levels.
  • Nutrients: Vitamin A deficiency may lead to sub-optimal plasma testosterone levels. The secosteroid vitamin D in levels of 400–1000 IU/d (10–25 µg/d) raises testosterone levels. Zinc deficiency lowers testosterone levels but over-supplementation has no effect on serum testosterone. There is limited evidence that low-fat diets may reduce total and free testosterone levels in men, and moderate evidence that short-term, very high protein diets (≥35% protein) decrease total testosterone levels in men.
  • Weight loss: Reduction in weight may result in an increase in testosterone levels. Fat cells synthesize the enzyme aromatase, which converts testosterone, the male sex hormone, into estradiol, the female sex hormone. However no clear association between body mass index and testosterone levels has been found.
  • Miscellaneous: Sleep: (REM sleep) increases nocturnal testosterone levels.
  • Behavior: Dominance challenges can, in some cases, stimulate increased testosterone release in men.
  • Foods: Natural or man-made antiandrogens including spearmint tea reduce testosterone levels. Licorice can decrease the production of testosterone and this effect is greater in females. There are also studies that suggest alcohol, dairy, and sugar can reduce T-levels as well.

Distribution

The plasma protein binding of testosterone is 98.0 to 98.5%, with 1.5 to 2.0% free or unbound. It is bound 65% to sex hormone-binding globulin (SHBG) and 33% bound weakly to albumin.

Metabolism

Testosterone metabolism in humans
Testosterone structures
The metabolic pathways involved in the metabolism of testosterone in humans. In addition to the transformations shown in the diagram, conjugation via sulfation and glucuronidation occurs with testosterone and metabolites that have one or more available hydroxyl (–OH) groups.

Both testosterone and 5α-DHT are metabolized mainly in the liver. Approximately 50% of testosterone is metabolized via conjugation into testosterone glucuronide and to a lesser extent testosterone sulfate by glucuronosyltransferases and sulfotransferases, respectively. An additional 40% of testosterone is metabolized in equal proportions into the 17-ketosteroids androsterone and etiocholanolone via the combined actions of 5α- and 5β-reductases, 3α-hydroxysteroid dehydrogenase, and 17β-HSD, in that order. Androsterone and etiocholanolone are then glucuronidated and to a lesser extent sulfated similarly to testosterone. The conjugates of testosterone and its hepatic metabolites are released from the liver into circulation and excreted in the urine and bile. Only a small fraction (2%) of testosterone is excreted unchanged in the urine.

In the hepatic 17-ketosteroid pathway of testosterone metabolism, testosterone is converted in the liver by 5α-reductase and 5β-reductase into 5α-DHT and the inactive 5β-DHT, respectively. Then, 5α-DHT and 5β-DHT are converted by 3α-HSD into 3α-androstanediol and 3α-etiocholanediol, respectively. Subsequently, 3α-androstanediol and 3α-etiocholanediol are converted by 17β-HSD into androsterone and etiocholanolone, which is followed by their conjugation and excretion. 3β-Androstanediol and 3β-etiocholanediol can also be formed in this pathway when 5α-DHT and 5β-DHT are acted upon by 3β-HSD instead of 3α-HSD, respectively, and they can then be transformed into epiandrosterone and epietiocholanolone, respectively. A small portion of approximately 3% of testosterone is reversibly converted in the liver into androstenedione by 17β-HSD.

In addition to conjugation and the 17-ketosteroid pathway, testosterone can also be hydroxylated and oxidized in the liver by cytochrome P450 enzymes, including CYP3A4, CYP3A5, CYP2C9, CYP2C19, and CYP2D6. 6β-Hydroxylation and to a lesser extent 16β-hydroxylation are the major transformations. The 6β-hydroxylation of testosterone is catalyzed mainly by CYP3A4 and to a lesser extent CYP3A5 and is responsible for 75 to 80% of cytochrome P450-mediated testosterone metabolism. In addition to 6β- and 16β-hydroxytestosterone, 1β-, 2α/β-, 11β-, and 15β-hydroxytestosterone are also formed as minor metabolites. Certain cytochrome P450 enzymes such as CYP2C9 and CYP2C19 can also oxidize testosterone at the C17 position to form androstenedione.

Two of the immediate metabolites of testosterone, 5α-DHT and estradiol, are biologically important and can be formed both in the liver and in extrahepatic tissues. Approximately 5 to 7% of testosterone is converted by 5α-reductase into 5α-DHT, with circulating levels of 5α-DHT about 10% of those of testosterone, and approximately 0.3% of testosterone is converted into estradiol by aromatase. 5α-Reductase is highly expressed in the male reproductive organs (including the prostate gland, seminal vesicles, and epididymides), skin, hair follicles, and brain and aromatase is highly expressed in adipose tissue, bone, and the brain. As much as 90% of testosterone is converted into 5α-DHT in so-called androgenic tissues with high 5α-reductase expression, and due to the several-fold greater potency of 5α-DHT as an AR agonist relative to testosterone, it has been estimated that the effects of testosterone are potentiated 2- to 3-fold in such tissues.

Levels

Total levels of testosterone in the body have been reported as 264 to 916 ng/dL (nanograms per deciliter) in non-obese European and American men age 19 to 39 years, while mean testosterone levels in adult men have been reported as 630 ng/dL. Although commonly used as a reference range, some physicians have disputed the use of this range to determine hypogonadism. Several professional medical groups have recommended that 350 ng/dL generally be considered the minimum normal level, which is consistent with previous findings. Levels of testosterone in men decline with age. In women, mean levels of total testosterone have been reported to be 32.6 ng/dL. In women with hyperandrogenism, mean levels of total testosterone have been reported to be 62.1 ng/dL.

Measurement

Testosterone's bioavailable concentration is commonly determined using the Vermeulen calculation or more precisely using the modified Vermeulen method, which considers the dimeric form of sex hormone-binding globulin.

Both methods use chemical equilibrium to derive the concentration of bioavailable testosterone: in circulation, testosterone has two major binding partners, albumin (weakly bound) and sex hormone-binding globulin (strongly bound). These methods are described in detail in the accompanying figure.

History

Nobel Prize winner, Leopold Ruzicka of Ciba, a pharmaceutical industry giant that synthesized testosterone

A testicular action was linked to circulating blood fractions – now understood to be a family of androgenic hormones – in the early work on castration and testicular transplantation in fowl by Arnold Adolph Berthold (1803–1861). Research on the action of testosterone received a brief boost in 1889, when the Harvard professor Charles-Édouard Brown-Séquard (1817–1894), then in Paris, self-injected subcutaneously a "rejuvenating elixir" consisting of an extract of dog and guinea pig testicle. He reported in The Lancet that his vigor and feeling of well-being were markedly restored but the effects were transient, and Brown-Séquard's hopes for the compound were dashed. Suffering the ridicule of his colleagues, he abandoned his work on the mechanisms and effects of androgens in human beings.

In 1927, the University of Chicago's Professor of Physiologic Chemistry, Fred C. Koch, established easy access to a large source of bovine testicles – the Chicago stockyards – and recruited students willing to endure the tedious work of extracting their isolates. In that year, Koch and his student, Lemuel McGee, derived 20 mg of a substance from a supply of 40 pounds of bovine testicles that, when administered to castrated roosters, pigs and rats, re-masculinized them. The group of Ernst Laqueur at the University of Amsterdam purified testosterone from bovine testicles in a similar manner in 1934, but the isolation of the hormone from animal tissues in amounts permitting serious study in humans was not feasible until three European pharmaceutical giants – Schering (Berlin, Germany), Organon (Oss, Netherlands) and Ciba (Basel, Switzerland) – began full-scale steroid research and development programs in the 1930s.

The Organon group in the Netherlands were the first to isolate the hormone, identified in a May 1935 paper "On Crystalline Male Hormone from Testicles (Testosterone)". They named the hormone testosterone, from the stems of testicle and sterol, and the suffix of ketone. The structure was worked out by Schering's Adolf Butenandt, at the Chemisches Institut of Technical University in Gdańsk.

The chemical synthesis of testosterone from cholesterol was achieved in August that year by Butenandt and Hanisch. Only a week later, the Ciba group in Zurich, Leopold Ruzicka (1887–1976) and A. Wettstein, published their synthesis of testosterone. These independent partial syntheses of testosterone from a cholesterol base earned both Butenandt and Ruzicka the joint 1939 Nobel Prize in Chemistry. Testosterone was identified as 17β-hydroxyandrost-4-en-3-one (C19H28O2), a solid polycyclic alcohol with a hydroxyl group at the 17th carbon atom. This also made it obvious that additional modifications on the synthesized testosterone could be made, i.e., esterification and alkylation.

The partial synthesis in the 1930s of abundant, potent testosterone esters permitted the characterization of the hormone's effects, so that Kochakian and Murlin (1936) were able to show that testosterone raised nitrogen retention (a mechanism central to anabolism) in the dog, after which Allan Kenyon's group was able to demonstrate both anabolic and androgenic effects of testosterone propionate in eunuchoidal men, boys, and women. The period of the early 1930s to the 1950s has been called "The Golden Age of Steroid Chemistry", and work during this period progressed quickly.

Other species

Testosterone is observed in most vertebrates. Testosterone and the classical nuclear androgen receptor first appeared in gnathostomes (jawed vertebrates). Agnathans (jawless vertebrates) such as lampreys do not produce testosterone but instead use androstenedione as a male sex hormone. Fish make a slightly different form called 11-ketotestosterone. Its counterpart in insects is ecdysone. The presence of these ubiquitous steroids in a wide range of animals suggest that sex hormones have an ancient evolutionary history.
