Oedipus Rex, also known by its Greek title, Oedipus Tyrannus (Ancient Greek: Οἰδίπους Τύραννος, pronounced [oidípuːs týrannos]), or Oedipus the King, is an Athenian tragedy written by Sophocles. The play is thought to have been first performed c.429 BC, although this is highly uncertain. Although the play won only second place at its initial performance, it was later considered by Aristotle to be one of the greatest Greek tragedies, and is now widely considered one of the greatest plays of Western literature, and the most famous of all Greek tragedies.

Oedipus Rex is likely the fourth out of the seven surviving plays by Sophocles. It is one of three surviving plays that deal with the story of Oedipus and Thebes. Of the three, Oedipus Rex was the second to be written, following Antigone by about a dozen years. However, in terms of the chronology of events described by the plays, it comes first, followed by Oedipus at Colonus and then Antigone.

Prior to the start of Oedipus Rex, Oedipus has become the king of Thebes while unwittingly fulfilling a prophecy that he would kill his father, Laius (the previous king), and marry his mother, Jocasta (whom Oedipus took as his queen after solving the riddle of the Sphinx). The action of Sophocles' play concerns Oedipus' search for the murderer of Laius in order to end a plague ravaging Thebes, unaware that the killer he is looking for is none other than himself. At the end of the play, after the truth finally comes to light, Jocasta hangs herself while Oedipus, horrified at his patricide and incest, proceeds to gouge out his own eyes in despair.

In his Poetics, Aristotle refers several times to the play in order to exemplify aspects of the genre of tragedy.

Title

Although the play is best known as Oedipus Rex, this title is anachronistic as "Rex" is the Latin word for king. Originally, to the ancient Greeks, the title was simply Oedipus (Οἰδίπους), as it is referred to by Aristotle in the Poetics. It is thought to have been renamed Oedipus Tyrannus to distinguish it from Oedipus at Colonus, a later play by Sophocles. The literal translation of this title is Oedipus the Tyrant. In antiquity, the term "tyrant" referred to a ruler with no legitimate claim to rule, but it did not necessarily have a negative connotation.

Context

Curse upon Laius

The misfortunes of Thebes are believed to be the result of a curse laid upon Laius for the time he had violated the sacred laws of hospitality (Greek: xenia).

In his youth, Laius was taken in as a guest by Pelops, king of Elis, where he would become tutor to the king's youngest son, Chrysippus, in chariot racing. Apollo, the protector of youth and boys, cursed him for kidnapping and raping Chrysippus.

Birth of Oedipus

When Laius's son is born, he consults an oracle as to his fortune. To his horror, the oracle reveals that Laius "is doomed to perish by the hand of his own son." Laius binds the infant's feet together with a pin and orders Jocasta to kill him. Unable to do so to her own son, Jocasta orders a servant to expose the infant on a mountaintop. The servant, moved by pity, gives the child to a shepherd, who unbinds the infant's ankles, and names him Oedipus, "swollen foot". The shepherd brings the infant to Corinth, and presents him to the childless king Polybus, who raises Oedipus as his own son.

Oedipus and the Oracle

As he grows to manhood, Oedipus hears a rumour that he is not truly the son of Polybus and his wife, Merope. He asks the Delphic Oracle who his parents really are. The Oracle seems to ignore this question, telling him instead that he is destined to "mate with [his] own mother, and shed/With [his] own hands the blood of [his] own sire." Desperate to avoid this terrible fate, Oedipus, who still believes that Polybus and Merope are his true parents, leaves Corinth for the city of Thebes.

Fulfilling prophecy

The old man

On the road to Thebes, Oedipus encounters an old man and his servants. The two begin to quarrel over whose chariot has the right of way. While the old man moves to strike the insolent youth with his scepter, Oedipus throws the man down from his chariot, killing him. Thus, the prophecy in which Oedipus slays his own father is fulfilled, as the old man—as Oedipus discovers later—was Laius, king of Thebes and true father to Oedipus.

Riddle of the Sphinx

Oedipus after he solves the riddle of the Sphinx (1864), Jean-Auguste-Dominique Ingres, Walters Art Museum

Arriving at Thebes, a city in turmoil, Oedipus encounters the Sphinx, a legendary beast with the head and breasts of a woman, the body of a lioness, and the wings of an eagle. The Sphinx, perched on a hill, was devouring Thebans and travelers one by one if they could not solve her riddle.

The precise riddle asked by the Sphinx varied in early traditions, and is not explicitly stated in Oedipus Rex, as the event precedes the play. However, according to the most widely related version of the riddle, the Sphinx asks, "What is the creature that walks on four legs in the morning, two legs at noon, and three in the evening?" Oedipus, blessed with great intelligence, answers correctly: "man" (Greek: anthrôpos), who crawls on all fours as an infant; walks upright in maturity; and leans on a stick in old age.

Bested by the prince, the Sphinx throws herself from a cliff, thereby ending the curse. Oedipus's reward for freeing Thebes from the Sphinx is kingship to the city and the hand of its dowager queen, Jocasta. None, at that point, realize that Jocasta is Oedipus's true mother. Thus, unbeknownst to either character, the remaining prophecy has been fulfilled.

Plot

Oedipus, King of Thebes, sends his brother-in-law, Creon, to ask the advice of the oracle at Delphi, concerning a plague ravaging Thebes. Creon returns to report that the plague is the result of religious pollution, since the murderer of their former king, Laius, has never been caught. Oedipus vows to find the murderer and curses him for causing the plague.

Oedipus summons the blind prophet Tiresias for help. Tiresias admits to knowing the answers to Oedipus's questions, but he refuses to speak, instead telling Oedipus to abandon his search. Angered by the seer's reply, Oedipus accuses him of complicity in Laius's murder. The offended Tiresias then reveals to the king that "you yourself are the criminal you seek". Oedipus does not understand how this could be, and supposes that Creon must have paid Tiresias to accuse him. The two argue vehemently, as Oedipus mocks Tiresias's lack of sight, and Tiresias retorts that Oedipus himself is blind. Eventually, the prophet leaves, muttering darkly that when the murderer is discovered, he shall be a native of Thebes, brother and father to his own children, and son and husband to his own mother.

Creon arrives to face Oedipus's accusations. The King demands that Creon be executed; however, the chorus persuades him to let Creon live. Jocasta, wife of first Laius and then Oedipus, enters and attempts to comfort Oedipus, telling him he should take no notice of prophets. As proof, she recounts an incident in which she and Laius received an oracle which never came true. The prophecy stated that Laius would be killed by his own son; instead, Laius was killed by bandits, at a fork in the road (τριπλαῖς ἁμαξιτοῖς, triplais amaxitois).

The mention of the place causes Oedipus to pause and ask for more details. Jocasta specifies the branch to Daulis on the way to Delphi. Recalling Tiresias's words, he asks Jocasta to describe Laius. The king then sends for a shepherd, the only surviving witness of the attack, to be brought from his fields to the palace.

Confused, Jocasta asks Oedipus what the matter is, and he tells her. Many years ago, at a banquet in Corinth, a man drunkenly accused Oedipus of not being his father's son. Oedipus went to Delphi and asked the oracle about his parentage. Instead of answering his question directly, the oracle prophesied that he would one day murder his father and sleep with his mother. Upon hearing this, Oedipus resolved never to return to Corinth. In his travels, he came to the very crossroads where Laius had been killed, and encountered a carriage that attempted to drive him off the road. An argument ensued, and Oedipus killed the travelers—including a man who matched Jocasta's description of Laius. However, Oedipus holds out hope that he was not Laius's killer, because Laius was said to have been murdered by several robbers. If the shepherd confirms that Laius was attacked by many men, then Oedipus will be in the clear.

A man arrives from Corinth with the message that Polybus, who raised Oedipus as his son, has died. To the surprise of the messenger, Oedipus is overjoyed, because he can no longer kill his father, thus disproving half of the oracle's prophecy. However, he still fears that he might somehow commit incest with his mother. Eager to set the king's mind at ease, the messenger tells him not to worry, because Merope is not his real mother.

The messenger explains that years earlier, while tending his flock on Mount Cithaeron, a shepherd from the household of Laius brought him an infant that he was instructed to dispose of. The messenger had then given the child to Polybus, who raised him. Oedipus asks the chorus if anyone knows the identity of the other shepherd, or where he might be now. They respond that he is the same shepherd who witnessed the murder of Laius, and whom Oedipus had already sent for. Jocasta, realizing the truth, desperately begs Oedipus to stop asking questions. When Oedipus refuses, the queen runs into the palace.

When the shepherd arrives, Oedipus questions him, but he begs to be allowed to leave without answering further. However, Oedipus presses him, finally threatening him with torture or execution. It emerges that the child he gave away was Laius's own son. In fear of a prophecy that the child would kill his father, Jocasta gave her son to the shepherd in order to be exposed upon the mountainside.

Everything is at last revealed, and Oedipus curses himself and fate before leaving the stage. The chorus laments how even a great man can be felled by fate, and following this, a servant exits the palace to speak of what has happened inside. Jocasta has hanged herself in her bedchamber. Entering the palace in anguish, Oedipus called on his servants to bring him a sword, that he might slay Jocasta with his own hand. But upon discovering the lifeless queen, Oedipus takes her down and removes the long gold pins from her dress. He then gouges out his own eyes in despair.

The blinded king now exits the palace, and begs to be exiled. Creon enters, saying that Oedipus shall be taken into the house until oracles can be consulted regarding what is best to be done. Oedipus's two daughters (and half-sisters), Antigone and Ismene, are sent out and Oedipus laments their having been born to such a cursed family. He begs Creon to watch over them, in hopes that they will live where there is opportunity for them, and to have a better life than their father. Creon agrees, before sending Oedipus back into the palace.

On an empty stage, the chorus repeats the common Greek maxim that "no man should be considered fortunate until he is dead."

Relationship with mythic tradition

The two cities of Troy and Thebes were the major focus of Greek epic poetry. The events surrounding the Trojan War were chronicled in the Epic Cycle, of which much remains, and those about Thebes in the Theban Cycle, which have been lost. The Theban Cycle recounted the sequence of tragedies that befell the house of Laius, of which the story of Oedipus is a part.

Homer's Odyssey (XI. 271ff.) contains the earliest account of the Oedipus myth when Odysseus encounters Jocasta (named Epicaste) in the underworld. Homer briefly summarises the story of Oedipus, including the incest, patricide, and Jocasta's subsequent suicide. However, in the Homeric version, Oedipus remains King of Thebes after the revelation and neither blinds himself, nor is sent into exile. In particular, it is said that the gods made the matter of his paternity known, whilst in Oedipus the King, Oedipus very much discovers the truth himself.

In 467 BC, Sophocles's fellow tragedian Aeschylus won first prize at the City Dionysia with a trilogy about the House of Laius, comprising Laius, Oedipus and Seven Against Thebes (the only play which survives). Since he did not write connected trilogies as Aeschylus did, Oedipus Rex focuses on the titular character while hinting at the larger myth obliquely, which was already known to the audience in Athens at the time.

Reception

P. Oxy. 1369, a fragmentary papyrus copy of Oedipus Rex, 4th century BC

The trilogy containing Oedipus Rex took second prize in the City Dionysia at its original performance. Aeschylus's nephew Philocles took first prize at that competition. However, in his Poetics, Aristotle considered Oedipus Rex to be the tragedy which best matched his prescription for how drama should be made.

Many modern critics agree with Aristotle on the quality of Oedipus Rex, even if they don't always agree on the reasons. For example, Richard Claverhouse Jebb claimed that "The Oedipus Tyrannus is in one sense the masterpiece of Attic tragedy. No other shows an equal degree of art in the development of the plot; and this excellence depends on the powerful and subtle drawing of the characters." Cedric Whitman noted that "the Oedipus Rex passes almost universally for the greatest extant Greek play". Whitman himself regarded the play as "the fullest expression of this conception of tragedy", that is the conception of tragedy as a "revelation of the evil lot of man", where a man may have "all the equipment for glory and honor" but still have "the greatest effort to do good" end in "the evil of an unbearable self for which one is not responsible". Edith Hall referred to Oedipus the King as "this definitive tragedy" and notes that "the magisterial subtlety of Sophocles' characterization thus lend credibility to the breathtaking coincidences", and notes the irony that "Oedipus can only fulfill his exceptional god-ordained destiny because Oedipus is a preeminently capable and intelligent human being." H. D. F. Kitto said about Oedipus Rex that "it is true to say that the perfection of its form implies a world order", although Kitto notes that whether or not that world order "is beneficent, Sophocles does not say."

The science revolution attributed to Thales began gaining political force, and this play offered a warning to the new thinkers. Kitto interprets the play as Sophocles's retort to the sophists, by dramatizing a situation in which humans face undeserved suffering through no fault of their own, but despite the apparent randomness of the events, the fact that they have been prophesied by the gods implies that the events are not random, despite the reasons being beyond human comprehension. Through the play, according to Kitto, Sophocles declares "that it is wrong, in the face of the incomprehensible and unmoral, to deny the moral laws and accept chaos. What is right is to recognize facts and not delude ourselves. The universe is a unity; if, sometimes, we can see neither rhyme nor reason in it we should not suppose it is random. There is so much that we cannot know and cannot control that we should not think and behave as if we do know and can control."

Oedipus Rex is widely regarded as one of the greatest plays, stories, and tragedies ever written. The Guardian's theatre critic Michael Billington included it in his list of the 101 greatest plays ever written.

Themes, irony and motifs

Fate, free will, or tragic flaw

A Greek amphora depicting Oedipus and the Sphinx, c.450 BC

Fate is a motif that often occurs in Greek writing, tragedies in particular. Likewise, where the attempt to avoid an oracle is the very thing that enables it to happen is common to many Greek myths. For example, similarities to Oedipus can be seen in the myth of Perseus's birth.

Two oracles in particular dominate the plot of Oedipus Rex. Jocasta relates the prophecy that was told to Laius before the birth of Oedipus (lines 711–4):

[The oracle] told him
that it was his fate that he should die a victim
at the hands of his own son, a son to be born
of Laius and me.

The oracle told to Laius tells only of the patricide, whereas the incest is missing. Prompted by Jocasta's recollection, Oedipus reveals the prophecy which caused him to leave Corinth (lines 791–3):

that I was fated to lie with my mother,
and show to daylight an accursed breed
which men would not endure, and I was doomed
to be murderer of the father that begot me.

The implication of Laius's oracle is ambiguous. One interpretation considers that the presentation of Laius's oracle in this play differs from that found in Aeschylus's Oedipus trilogy produced in 467 BC. Smith (2005) argues that "Sophocles had the option of making the oracle to Laius conditional (if Laius has a son, that son will kill him) or unconditional (Laius will have a son who will kill him). Both Aeschylus and Euripides write plays in which the oracle is conditional; Sophocles ... chooses to make Laius's oracle unconditional and thus removes culpability for his sins from Oedipus, for he could not have done other than what he did, no matter what action he took."

This interpretation is supported by Jocasta's repetition of the oracle at lines 854–855: "Loxias declared that the king should be killed by/ his own son." In Greek, Jocasta uses the verb chrênai: "to be fated, necessary." This iteration of the oracle seems to suggest that it was unconditional and inevitable.

Other scholars have nonetheless argued that Sophocles follows tradition in making Laius's oracle conditional, and thus avoidable. They point to Jocasta's initial disclosure of the oracle at lines 711–14. In Greek, the oracle cautions: "hôs auton hexoi moira pros paidos thanein/ hostis genoit emou te kakeinou para." The two verbs in boldface indicate what is called a "future more vivid" condition: if a child is born to Laius, his fate to be killed by that child will overtake him.

Whatever the meaning of Laius's oracle, the one delivered to Oedipus is clearly unconditional. Given the modern conception of fate and fatalism, readers of the play have a tendency to view Oedipus as a mere puppet controlled by greater forces; a man crushed by the gods and fate for no good reason. This, however, is not an entirely accurate reading. While it is a mythological truism that oracles exist to be fulfilled, oracles do not cause the events that lead up to the outcome. In his landmark essay "On Misunderstanding the Oedipus Rex", E. R. Dodds draws upon Bernard Knox's comparison with Jesus' prophecy at the Last Supper that Peter would deny him three times. Jesus knows that Peter will do this, but readers would in no way suggest that Peter was a puppet of fate being forced to deny Christ. Free will and predestination are by no means mutually exclusive, and such is the case with Oedipus.

The oracle delivered to Oedipus is what is often called a "self-fulfilling prophecy", whereby a prophecy itself sets in motion events that conclude with its own fulfilment. This, however, is not to say that Oedipus is a victim of fate and has no free will. The oracle inspires a series of specific choices, freely made by Oedipus, which lead him to kill his father and marry his mother. Oedipus chooses not to return to Corinth after hearing the oracle, just as he chooses to head toward Thebes, to kill Laius, and to take Jocasta specifically as his wife. In response to the plague at Thebes, he chooses to send Creon to the Oracle for advice and then to follow that advice, initiating the investigation into Laius's murder. None of these choices are predetermined.

Oedipus and Antigone, by Charles Jalabert

Another characteristic of oracles in myth is that they are almost always misunderstood by those who hear them; hence Oedipus misunderstanding the significance of the Delphic Oracle. He visits Delphi to find out who his real parents are and assumes that the Oracle refuses to answer that question, offering instead an unrelated prophecy which forecasts patricide and incest. Oedipus's assumption is incorrect: the Oracle does, in a way, answer his question. On closer analysis, the oracle contains essential information which Oedipus seems to neglect. The wording of the Oracle: "I was doomed to be murderer of the father that begot me" refers to Oedipus's real, biological father. Likewise the mother with polluted children is defined as the biological one. The wording of the drunken guest on the other hand: "you are not your father's son" defines Polybus as only a foster father to Oedipus. The two wordings support each other and point to the "two sets of parents" alternative. Thus the question of two sets of parents, biological and foster, is raised. Oedipus's reaction to the Oracle is irrational: he states he did not get any answer and he flees in a direction away from Corinth, showing that he firmly believed at the time that Polybus and Merope are his real parents.

The scene with the drunken guest constitutes the end of Oedipus's childhood. He can no longer ignore a feeling of uncertainty about his parentage. However, after consulting the Oracle this uncertainty disappears, strangely enough, and is replaced by a totally unjustified certainty that he is the son of Merope and Polybus. We have said that this irrational behaviour—his hamartia, as Aristotle puts it—is due to the repression of a whole series of thoughts in his consciousness, in fact everything that referred to his earlier doubts about his parentage.

State control

The exploration of the theme of state control in Oedipus Rex is paralleled by the examination of the conflict between the individual and the state in Antigone. The dilemma that Oedipus faces here is similar to that of the tyrannical Creon: each man has, as king, made a decision that his subjects question or disobey; and each king misconstrues both his own role as a sovereign and the role of the rebel. When informed by the blind prophet Tiresias that religious forces are against him, each king claims that the priest has been corrupted. It is here, however, that their similarities come to an end: while Creon sees the havoc he has wreaked and tries to amend his mistakes, Oedipus refuses to listen to anyone. (The above text comes almost directly from David Grene's introduction to Sophocles I, University of Chicago Press, 1954.)

Irony

Sophocles uses dramatic irony to present the downfall of Oedipus. At the beginning of the story, Oedipus is portrayed as "self-confident, intelligent and strong willed." By the end, it is within these traits that he finds his demise.

One of the most significant instances of irony in this tragedy is when Tiresias hints to Oedipus what he has done; that he has slain his own father and married his own mother (lines 457–60):

To his children he will discover that he is both brother and father.
To the woman who gave birth to him he is son and husband and to his father, both, a sharer of his bed and his murderer.
Go into your palace then, king Oedipus, and think about these things and if you find me a liar then you can truly say I know nothing of prophecies.

The audience knows the truth and what would be the fate of Oedipus. Oedipus, on the other hand, chooses to deny the reality that has confronted him. He ignores the word of Tiresias and continues on his journey to find the supposed killer. His search for a murderer is yet another instance of irony. Oedipus, determined to find the one responsible for King Laius's death, announces to his people (lines 247–53):

I hereby call down curses on this killer ...
that horribly, as he is horrible,
he may drag out his wretched unblessed days.
This too I pray: Though he be of my house,
if I learn of it, and let him still remain,
may I receive the curse I have laid on others.

This is ironic as Oedipus is, as he discovers, the slayer of Laius, and the curse he wishes upon the killer, he has actually wished upon himself. Glassberg (2017) explains that "Oedipus has clearly missed the mark. He is unaware that he is the one polluting agent he seeks to punish. He has inadequate knowledge."

Sight and blindness

Vittorio Gassman as Oedipus

Literal and metaphorical references to eyesight appear throughout Oedipus Rex. Clear vision serves as a metaphor for insight and knowledge, yet the clear-eyed Oedipus is blind to the truth about his origins and inadvertent crimes. The prophet Tiresias, on the other hand, although literally blind, "sees" the truth and relays what is revealed to him. Only after Oedipus gouges out his own eyes, physically blinding himself, does he gain prophetic ability, as exhibited in Oedipus at Colonus. It is deliberately ironic that the "seer" can "see" better than Oedipus, despite being blind. Tiresias, in anger, expresses such (lines 495–500):

Since you have chosen to insult my blindness—
you have your eyesight, and you do not see
how miserable you are, or where you live,
or who it is who shares your household.
Do you know the family you come from?
Without your knowledge you've become
the enemy of your own kindred

Tyranny

Oedipus switches back and forth calling Laius a tyrant (lines 128–129) and a king (lines 254–256) throughout the duration of the play. This is done as a way to make Laius his equal in terms of ruling. Laius was a legitimate king, whereas Oedipus had no legitimate claim to rule. Oedipus's claims that Laius is a tyrant hint at his own insecurities of being a tyrant.

The tyranny brought down the way it was, what

"troubles" could keep you from looking into it?

For even if a god weren't forcing this on you

you shouldn't leave it festering so, and this

the case of a noble man, your murdered king.

Sigmund Freud

Sigmund Freud wrote a notable passage in Interpretation of Dreams regarding the destiny of Oedipus, as well as the Oedipus complex. He analyzes why this play, Oedipus Rex, written in Ancient Greece, is so effective even to a modern audience:

"His destiny moves us only because it might have been ours—because the oracle laid the same curse upon us before our birth as upon him. It is the fate of all of us, perhaps, to direct our first sexual impulse towards our mother and our first hatred and our first murderous wish against our father. Our dreams convince us that this is so."

Freud goes on to indicate, however, that the "primordial urges and fears" that are his concern are not found primarily in the play by Sophocles, but exist in the myth the play is based on. He refers to Oedipus Rex as a "further modification of the legend", one that originates in a "misconceived secondary revision of the material, which has sought to exploit it for theological purposes".

In her article, "Oedipal Textuality: Reading Freud's Reading of Oedipus", Cynthia Chase explains Oedipus Rex as a story of psychoanalysis in relation to the riddles in the story and Oedipus trying to uncover his truth.

Parsifal

The Parsifal story is the "reverse" of the Oedipus myth (cf. Claude Lévi-Strauss).

Adaptations

Film adaptations

The first English-language adaption, Oedipus Rex (1957), was directed by Tyrone Guthrie and starred Douglas Campbell as Oedipus. In this version, the entire play is performed by the cast in masks (Greek: prosopon), as actors did in ancient Greek theatre.

The second English-language film version, Oedipus the King (1968), was directed by Philip Saville and filmed in Greece. Unlike Guthrie's film, this version shows the actors' faces, as well as boasting an all-star cast, including Christopher Plummer as Oedipus; Lilli Palmer as Jocasta; Orson Welles as Tiresias; Richard Johnson as Creon; Roger Livesey as the Shepherd; and Donald Sutherland as the Leading Member of the Chorus. Sutherland's voice, however, was dubbed by another actor. The film went a step further than the play by actually showing, in flashback, the murder of Laius (portrayed by Friedrich Ledebur). It also shows Oedipus and Jocasta in bed together, making love. Though released in 1968, this film was not seen in Europe or the US until the 1970s and 1980s after legal release and distribution rights were granted to video and television.

In Italy, Pier Paolo Pasolini directed Edipo Re (1967), a modern interpretation of the play.

Toshio Matsumoto's film, Funeral Parade of Roses (1969), is a loose adaptation of the play and an important work of the Japanese New Wave.

In Colombia, writer Gabriel García Márquez adapted the story in Edipo Alcalde, bringing it to the real-world situation of Colombia at the time.

The Nigerian film The Gods are STILL not to Blame (2012) was produced by Funke Fayoyin, premiering at Silverbird Galleria in Lagos.

Park Chan-wook's South Korean film, Oldboy (2003), was inspired by the play while making several notable changes to allow it to work in a modern South-Korean setting. The film even alters the iconic twist, causing many American critics to overlook the connection. It received widespread acclaim, and is seen in South Korea as the definitive adaptation.

Stage adaptations

Play by the Celje Slovene People's Theatre in 1968

The composer Igor Stravinsky wrote the opera-oratorio Oedipus Rex, which premiered in 1927 at the Théâtre Sarah Bernhardt, Paris. It is scored for orchestra, speaker, soloists, and male chorus. The libretto, based on Sophocles's tragedy, was written by Jean Cocteau in French and then translated by Abbé Jean Daniélou into Latin. The narration, however, is performed in the language of the audience. The work was written towards the beginning of Stravinsky's neoclassical period and is considered one of the finest works from this phase of the composer's career. He had considered setting the language of the work in Ancient Greek, but decided ultimately on Latin, as "a medium not dead but turned to stone".

Carl Orff wrote Oedipus der Tyrann (1959), an opera consisting of a prologue and five acts, to Friedrich Hölderlin's 1804 German translation of Sophocles' text.

Nigerian writer Ola Rotimi adapted Oedipus Rex into a 1968 play and novel, titling it The Gods Are Not to Blame.

Dancer and choreographer Martha Graham adapted Oedipus Rex into a short ballet entitled Night Journey, premiering in 1947. In this adaptation, the action focuses not on Oedipus, but upon Jocasta, reflecting on her strange destiny.

Composer Wolfgang Rihm used the play as a basis for his 1987 opera Oedipus, also writing the libretto in German which includes related texts by Friedrich Nietzsche and Heiner Müller. It premiered at the Deutsche Oper Berlin, directed by Götz Friedrich in a performance broadcast live.

Robert Icke's adaptation Oedipus premiered at Toneelgroep Amsterdam in 2018, before an English-language transfer in 2025 to the Wyndham's Theatre, West End, and to Studio 54, Broadway, starring Mark Strong and Lesley Manville.

TV/radio adaptations

Don Taylor's 1986 translation/adaptation of Oedipus Rex using the English title Oedipus the King formed part of the BBC's Theban Plays trilogy. It starred Michael Pennington as Oedipus, with Claire Bloom as Jocasta, John Gielgud as Tiresias, and John Shrapnel as Creon. The actors performed in modern dress.

In 1977, CBS Radio Mystery Theater broadcast a version of the story called "So Shall Ye Reap", set in 1851 in what was then the U.S. Territory of New Mexico.

In 1987, Brazilian TV Globo broadcast the soap opera Mandala, a loose adaptation set in modern times starring Vera Fischer as Jocasta.

In 2017, BBC Radio 3 broadcast a production of Anthony Burgess' translation of the play with Christopher Eccleston as Oedipus and Fiona Shaw as Tiresias/Second Elder. John Shrapnel, who starred as Creon in the 1986 BBC television version, played the First Elder.

Other television portrayals of Oedipus include that of Christopher Plummer (1957), Ian Holm (1972), and Patrick Stewart (1977).

Parodies

Peter Schickele parodies both the story of Oedipus Rex and the music of Stravinsky's opera-oratorio of the same name in Oedipus Tex, a Western-themed oratorio purportedly written by P. D. Q. Bach. It was released in 1990 on the album Oedipus Tex and Other Choral Calamities.

Chrysanthos Mentis Bostantzoglou makes a parody of the tragedy in his comedy Medea (1993).

In episode ten of the second season of the Australian satirical comedy show CNNNN, a short animation in the style of a Disney movie trailer, complete with jaunty music provided by Andrew Hansen, parodies Oedipus Rex. Apart from being advertised as "fun for the whole family", the parody is also mentioned at other times during that same episode, such as in a satirical advertisement in which orphans are offered a free "Oedipus Rex ashes urn" as a promotional offer after losing a relative.

John Barth's novel Giles Goat-Boy contains a forty-page parody of the full text of Oedipus Rex called Taliped Decanus.

Tom Lehrer wrote and performed a comedic song based upon Oedipus Rex in 1959.

Bo Burnham references Oedipus in songs "Words Words Words" and "Rant", both part of his album, Words Words Words.

In 1968, Argentinean comedy-musical group Les Luthiers composed a parody of the play titled "Epopeya de Edipo de Tebas" (Oedipus of Thebes' Epos).

Artificial insemination

From Wikipedia, the free encyclopedia

Artificial insemination is the deliberate introduction of sperm into the cervix or uterine cavity for the purpose of achieving pregnancy through in vivo fertilization by means other than sexual intercourse. It is a fertility treatment for humans, and is a common practice in animal breeding, including cattle (see frozen bovine semen) and pigs.

Artificial insemination may employ assisted reproductive technology, sperm donation and animal husbandry techniques. Artificial insemination techniques available include intracervical insemination (ICI) and intrauterine insemination (IUI). Where gametes from a third party are used, the procedure may be known as 'assisted insemination'.

Humans

History

The first recorded case of artificial insemination was by Lazzaro Spallanzani in 1784, who performed it on a dog. It was followed in 1790 by John Hunter, who helped impregnate a linen draper's wife. The first reported case of artificial insemination by donor occurred in 1884: William H. Pancoast, a professor in Philadelphia, took sperm from his "best looking" student to inseminate an anesthetized woman without her knowledge. The case was reported 25 years later in a medical journal. The sperm bank was developed in Iowa starting in the 1950s in research conducted by University of Iowa medical school researchers Jerome K. Sherman and Raymond Bunge.

In 1916, Australian eugenicist Marion Louisa Piddington published a pseudonymous tract titled Via Nuova or Science & Maternity in which she called for a programme of mass artificial insemination for the sweethearts of soldiers who had been killed in World War I. She described this as a "conscription of the virgins" – comparable to the conscription of men for military service – who would receive "artificial insemination from a eugenically-desirable donor". Piddington promoted her scheme for several years in Australia, Britain and the United States under the name of "scientific motherhood", but it was poorly received.

In the United Kingdom, British obstetrician Mary Barton founded one of the first fertility clinics to offer donor insemination in the 1930s, with her husband Bertold Wiesner fathering hundreds of offspring.

In the 1980s, direct intraperitoneal insemination (DIPI) was occasionally used, where doctors injected sperm into the lower abdomen through a surgical hole or incision, with the intention of letting them find the oocyte at the ovary or after entering the genital tract through the ostium of the fallopian tube.

Patients and gamete donors

Artificial insemination (AI) is a medical procedure in which sperm is introduced into a woman's reproductive system to achieve pregnancy without sexual intercourse. The sperm used may come from the recipient's partner or from a donor, whose identity may be known or anonymous. Various methods exist to obtain sperm for use in artificial insemination.

In 2016, an article was published in Seventeen magazine that highlighted the story of Kacie Saxer-Taulbee, a teenager conceived from a sperm donor father. Using her donor's cryobank number in the Donor Sibling Registry, she managed to find other siblings conceived from the same donor. They became known as the "5010ers" and formed a Facebook group to keep in touch.

Barriers for patients and donors

Some countries have laws which restrict and regulate who can donate sperm and who is able to receive artificial insemination.

Preparations

Timing is critical, as the window and opportunity for fertilization is little more than twelve hours from the release of the ovum. To increase the chance of success, the woman's menstrual cycle is closely observed, often using ovulation kits, ultrasounds or blood tests, such as basal body temperature tests over, noting the color and texture of the vaginal mucus, and the softness of the nose of her cervix. To improve the success rate of artificial insemination, drugs to create a stimulated cycle may be used, but the use of such drugs also results in an increased chance of a multiple birth.

Sperm can be provided fresh or washed.

Techniques

The human female reproductive system. The cervix is part of the uterus. The cervical canal connects the interiors of the uterus and vagina.

Semen used is either fresh, raw, or frozen.

Intracervical

Intracervical insemination (ICI) is the method of artificial insemination which most closely mimics the natural ejaculation of semen by the penis into the vagina during sexual intercourse. It is painless and is the simplest and most common method of artificial insemination involving the introduction of unwashed or raw semen into the vagina at the entrance to the cervix, usually by means of a needle-less syringe. The vagina acts as a filter to separate out the sperm from other chemicals in the ejaculate, as with intercourse, so that only sperm pass through the cervix on their way to the uterus.

Although ICI is the simplest method of artificial insemination, a meta-analysis has shown no difference in live birth rates compared with IUI.

During ICI, air is expelled from a needleless syringe which is then filled with semen which has been allowed to liquify. A specially designed syringe, wider and with a more rounded end, may be used for this purpose. Any further enclosed air is removed by gently pressing the plunger forward. The woman lies on her back and the syringe is inserted into the vagina. Care is optimal when inserting the syringe, so that the tip is as close to the entrance to the cervix as possible. A vaginal speculum may be used for this purpose and a catheter may be attached to the tip of the syringe to ensure delivery of the semen as close to the entrance to the cervix as possible. The plunger is then slowly pushed forward and the semen in the syringe is gently emptied deep into the vagina. It is important that the syringe is emptied slowly for safety and for the best results, bearing in mind that the purpose of the procedure is to replicate as closely as possible a natural deposit of the semen in the vagina. The syringe (and catheter if used) may be left in place for several minutes before removal. The woman can bring herself to orgasm so that the cervix 'dips down' into the pool of semen, again replicating closely vaginal intercourse, and this may improve the success rate.

When performed at home without the presence of a professional, aiming the sperm in the vagina at the neck of the cervix may be more difficult to achieve and the effect may be to 'flood' the vagina with semen, rather than to target it specifically at the entrance to the cervix. This procedure is sometimes referred to as 'intravaginal insemination' (IVI).

A conception cap, which is a form of conception device, may be inserted into the vagina following insemination and may be left in place for several hours

Intrauterine

Intrauterine insemination (IUI) involves injection of 'washed' sperm directly into the uterus with a catheter. Washing involves the removal of chemicals other than sperm which are in the natural ejaculate. In forms of vaginal insemination, including artificial vaginal insemination and ICI, these chemicals will be filtered out by the vagina. Insemination in this way also means that the sperm do not have to swim through the cervix which is coated with a mucus layer. This layer of mucus can slow down the passage of sperm and can result in many sperm perishing before they can enter the uterus. Donor sperm is sometimes tested for mucus penetration if it is to be used for ICI inseminations but partner sperm may or may not be able to pass through the cervix. In these cases, the use of IUI can provide a more efficient delivery of the sperm. In general terms, IUI is usually regarded as more efficient than ICI or IVI. It is therefore the method of choice for single and lesbian women wishing to conceive using donor sperm since this group of recipients usually require artificial insemination because they do not have a male partner, not because they have medical problems. Owing to the high number of these recipients using donor sperm services, IUI is therefore the most popular method of insemination today at a fertility clinic. The term 'artificial insemination' has, in many cases, come to mean IUI insemination.

It is important that washed sperm is used because unwashed sperm may elicit uterine cramping, expelling the semen and causing pain, due to content of prostaglandins. (Prostaglandins are also the compounds responsible for causing the myometrium to contract and expel the menses from the uterus, during menstruation.) Resting on the table for fifteen minutes after an IUI is optimal for the woman to increase the pregnancy rate.

Using this technique, as with ICI, fertilization takes place naturally in the external part of the fallopian tubes in the same way that occurs following intercourse.

For heterosexual couples, the indications to perform an intrauterine insemination are usually a moderate male factor, the incapability to ejaculate in vagina and an idiopathic infertility. A short period of ejaculatory abstinence before intrauterine insemination is associated with higher pregnancy rates. For the man, a TMS of more than 5 million per ml is optimal. In practice, donor sperm will satisfy these criteria and since IUI is a more efficient method of artificial insemination than ICI and, because of its generally higher success rate, IUI is usually the insemination procedure of choice for single women and lesbians using donor semen in a fertility centre. Lesbians and single women are less likely to have fertility issues of their own and enabling donor sperm to be inserted directly into the womb will often produce a better chance of conceiving. A 2019 showed that pregnancy rates were similar between lesbian women and heterosexual women undergoing IUI. However, it was found that there is a significantly higher multiple gestation rate among lesbian women undergoing ovulation induction (OI) when compared to lesbian women undergoing natural cycles.

Unlike ICI, intrauterine insemination normally requires a medical practitioner to perform the procedure. One of the requirements is to have at least one permeable tube, proved by hysterosalpingography. The infertility duration is also important. A female under 30 years of age has optimal chances with IUI; A promising cycle is one that offers two follicles measuring more than 16 mm, and estrogen of more than 500 pg/mL on the day of hCG administration. However, GnRH agonist administration at the time of implantation does not improve pregnancy outcome in intrauterine insemination cycles according to a randomized controlled trial. One of the prominent private clinic in Europe has published a data A multiple logistic regression model showed that sperm origin, maternal age, follicle count at hCG administration day, follicle rupture, and the number of uterine contractions observed after the second insemination procedure were associated with the live-birth rate The steps to follow in order to perform an intrauterine insemination are:

  • Mild controlled ovarian stimulation (COS): there is no control of how many oocytes are at the same time when stimulating ovulation. For that reason, it is necessary to check the amount being ovulated via ultrasound (checking the amount of follicles developing at the same time) and administering the desired amount of hormones.
  • Ovulation induction: using substances known as ovulation inductors.
  • Semen capacitation: wash and centrifugation, swim-up, or gradient. The insemination should not be performed later than an hour after capacitation. 'Washed sperm' may be purchased directly from a sperm bank if donor semen is used, or 'unwashed semen' may be thawed and capacitated before performing IUI insemination, provided that the capacitation leaves a minimum of, usually, five million motile sperm.
  • Luteal phase support: a lack of progesterone in the endometrium could end a pregnancy. To avoid that 200 mg/day of micronized progesterone are administered via vagina. If there is pregnancy, this hormone is kept administering until the tenth week of pregnancy.

The cost breakdown for Intrauterine Insemination (IUI) involves several components. The procedure itself typically ranges from $300 to $1,000 per cycle without insurance. The cost of the sperm may vary widely, with prices per vial ranging from $500 to $1,000 or more from a sperm bank. Additional expenses might include consultation fees, ovulation-inducing medication, ultrasounds, and blood tests.

The extent of insurance coverage for fertility treatments, including Intrauterine Insemination (IUI), varies considerably. Some insurance plans may cover some of the costs, while others may not provide any financial support for fertility treatments. Coverage depends on various factors, such as the insurance plan, state policies and regulations, and the underlying cause of infertility. Several states have mandated insurers to provide coverage for infertility services.

IUI can be used in conjunction with controlled ovarian hyperstimulation (COH). Clomiphene Citrate is the first line, Letrozole is second line, in order to stimulate ovaries before moving on to IVF. Still, advanced maternal age causes decreased success rates; women aged 38–39 years appear to have reasonable success during the first two cycles of ovarian hyperstimulation and IUI. However, for women aged over 40 years, there appears to be no benefit after a single cycle of COH/IUI. Medical experts therefore recommend considering in vitro fertilization after one failed COH/IUI cycle for women aged over 40 years.

A double intrauterine insemination theoretically increases pregnancy rates by decreasing the risk of missing the fertile window during ovulation. However, a randomized trial of insemination after ovarian hyperstimulation found no difference in live birth rate between single and double intrauterine insemination. A Cochrane found uncertain evidence about the effect of IUI compared with timed intercourse or expectant management on live birth rates but IUI with controlled ovarian hyperstimulation is probably better than expectant management.

Due to the lack of reliable evidence from controlled clinical trials, it is not certain which semen preparation techniques are more effective (wash and centrifugation; swim-up; or gradient) in terms of pregnancy and live birth rates.

Intrauterine insemination success factors

Intrauterine insemination (IUI) procedures have shown to be more successful and effective with certain factors taken into account. One major factor is the health of the sperm that is used. Sperm motility, which is improved by the sperm washing procedure, sperm density, and the sperm concentration index, all of which are found through washing and studying of the health of the specimen, are major indicators of a positive pregnancy test following IUI.

The age of both the male and female (egg and sperm donors) involved in the process are extremely important. Although age has typically been pinned on the women as a determining factor, research shows that both male and female age has about equal impact on the success of the procedure. Along with age, the duration of fertility is also found to be a factor in IUI success, the longer one faces infertility, the lower the chance of a positive pregnancy test occurring. When people talk about age as a risk factor, they are generally speaking to the way in which the DNA in the eggs and sperm have increased probabilities of mutations.

Lastly, the biological factors of the female's body can have some impact on the success of the IUI procedure. The endometrial thickness at time of insemination is moderately important, though less of a concern than some of the other factors. The number of follicles developed, grown, and retrieved from the ovaries during ovarian stimulation is particularly important and a major success factor in fertility treatments. And lastly, for the female partner, the estradiol concentration within the body on the day of HCG administration.

Who IUI can be used for

Because IUI is less expensive and less invasive than other fertility options (for example, in vitro fertilisation, or IVF), it is typically the first outlet for those looking for fertility treatments. For individuals or couples who struggle with getting pregnant, but haven't explored any fertility treatments yet, they would be good candidates for IUI. IUI provides those with a more affordable and accessible outlet for fertility treatments, however, IUI may not be the most successful option if it is determined to be female factor infertility. IUI is also a very good option for single individuals who are using donor sperm, as donor sperm undergoes regulations and checks which may not be the case for a partner sperm donation. IUI can additionally be a good fertility outlet for lesbian or queer couples as they most often do not face infertility, and would most likely be using regulated and checked donor sperm. Furthermore, surrogates can be artificially inseminated through IUI to help other individuals and/or couples become pregnant with their sperm.

Intrauterine tuboperitoneal

Intrauterine tuboperitoneal insemination (IUTPI) involves injection of washed sperm into both the uterus and fallopian tubes. The cervix is then clamped to prevent leakage to the vagina, best achieved with a specially designed double nut bivalve (DNB) speculum. The sperm is mixed to create a volume of 10 ml, sufficient to fill the uterine cavity, pass through the interstitial part of the tubes and the ampulla, finally reaching the peritoneal cavity and the Pouch of Douglas where it would be mixed with the peritoneal and follicular fluid. IUTPI can be useful in unexplained infertility, mild or moderate male infertility, and mild or moderate endometriosis. In non-tubal sub fertility, fallopian tube sperm perfusion may be the preferred technique over intrauterine insemination.

Intratubal

Intratubal insemination (ITI) involves injection of washed sperm into the fallopian tube, although this procedure is no longer generally regarded as having any beneficial effect compared with IUI. ITI however, should not be confused with gamete intrafallopian transfer, where both eggs and sperm are mixed outside the woman's body and then immediately inserted into the fallopian tube where fertilization takes place.

LGBTQ+ concerns

Although many fertilization procedures, like IUI are typically carried out in a medical setting, society is increasingly recognizing the important role that this plays in the lives of individuals who might otherwise not conceive through heterosexual penetrative sexual intercourse. Artificial insemination using a sperm donor for LGBTQ+ individuals and couples is one of the more cost-effective avenues to parenting. While clinic based IUI may be open to many, it typically still includes hetero-reproductive narratives which dates from the early days of fertilization procedures when these were often exclusively for married couples and when there was a resistance in many societies to extend these services to the LGBTQ+ community. Indeed, in the early days, there were very few fertility clinics which would provide services to single women and lesbian couples. In the UK, notable pioneers in this respect were the British Pregnancy Advisory Service (BPAS) and the Pregnancy Advisory Service (PAS), both of which operated before statutory control of fertility services in 1992, and the London Women's Clinic (LWC) which provided artificial insemination to single women and lesbians from 1998. Most donor insemination procedures undertaken in many countries today are for lesbian couples or single mainly lesbian women, yet much of their rhetoric and advertising is directed at heterosexual couples. Indeed, many sperm banks seem reluctant to inform donors that most of their donations will be used for lesbians and single women. To improve the way society talks about and carries out donor insemination inclusive language may be used. One way to do this is to bring LGBTQ narratives into this process, with a particular emphasis on this being a family-centered process. Even in a medical setting, it is important to bring intimacy and family-centeredness into this process, as this promotes connectedness and inclusiveness in what can be seen as a hostile and discriminatory environment. LGBTQ couples or individuals typically have to navigate more complexities and barriers than heterosexual couples when undergoing fertility treatment, such as stigma and carrier decisions, so allowing room for intimacy and connectedness in the process can improve the experience for individuals, reduce stress, and minimize barriers that target marginalized individuals.

Lesbian couples may either select a friend or family member as their sperm donor or choose an anonymous donor. After a sperm donor is selected, a couple can proceed with donor sperm IUI. IUI is an economic option for same-sex couples and can be done without the use of medication. According to a study from 2021, lesbian women undergoing IUI had an average clinical pregnancy rate of 13.2% per cycle and 42.2% success rate giving the average number of cycles at 3.6.

Pregnancy rate

Approximate pregnancy rate as a function of total sperm count (may be twice as large as total motile sperm count). Values are for intrauterine insemination. (Old data, rates are likely higher these days)

The rates of successful pregnancy for artificial insemination are 10-15% per menstrual cycle using ICI, and 15–20% per cycle for IUI. In IUI, about 60 to 70% have achieved pregnancy after 6 cycles.

However, these pregnancy rates may be very misleading, since many factors have to be included to give a meaningful answer, e.g. definition of success and calculation of the total population. These rates can be influenced by age, overall reproductive health, and if the patient had an orgasm during the insemination. The literature is conflicting on immobilization after insemination has increasing the chances of pregnancy. Previous data suggests that it is statistically significant for the patient to remain immobile for 15 minutes after insemination, while another review article claims that it is not. A point of consideration, is that it does cost the patient or healthcare system to remain immobile for 15 minutes if it does increase the chances. For couples with unexplained infertility, unstimulated IUI is no more effective than natural means of conception.

The pregnancy rate also depends on the total sperm count, or, more specifically, the total motile sperm count (TMSC), used in a cycle. The success rate increases with increasing TMSC, but only up to a certain count, when other factors become limiting to success. The summed pregnancy rate of two cycles using a TMSC of 5 million (may be a TSC of ~10 million on graph) in each cycle is substantially higher than one single cycle using a TMSC of 10 million. However, although more cost-efficient, using a lower TMSC also increases the average time taken to achieve pregnancy. Women whose age is becoming a major factor in fertility may not want to spend that extra time.

Samples per child

The number of samples (ejaculates) required to give rise to a child varies substantially from person to person, as well as from clinic to clinic. However, the following equations generalize the main factors involved:

For intracervical insemination:

  • N is how many children a single sample can give rise to.
  • Vs is the volume of a sample (ejaculate), usually between 1.0 mL and 6.5 mL
  • c is the concentration of motile sperm in a sample after freezing and thawing, approximately 5–20 million per ml but varies substantially
  • rs is the pregnancy rate per cycle, between 10% and 35%
  • nr is the total motile sperm count recommended for vaginal insemination (VI) or intra-cervical insemination (ICI), approximately 20 million pr. ml.

The pregnancy rate increases with increasing number of motile sperm used, but only up to a certain degree, when other factors become limiting instead.

Derivation of the equation (click at right to view)
Approximate live birth rate (rs) among infertile couples as a function of total motile sperm count (nr). Values are for intrauterine insemination.

With these numbers, one sample would on average help giving rise to 0.1–0.6 children, that is, it actually takes on average 2–5 samples to make a child.

For intrauterine insemination, a centrifugation fraction (fc) may be added to the equation:

fc is the fraction of the volume that remains after centrifugation of the sample, which may be about half (0.5) to a third (0.33).

On the other hand, only 5 million motile sperm may be needed per cycle with IUI (nr=5 million)

Thus, only 1–3 samples may be needed for a child if used for IUI.

Social implications

One of the key issues arising from the rise of dependency on assisted reproductive technology (ARTs) is the pressure placed on couples to conceive, "where children are highly desired, parenthood is culturally mandatory, and childlessness socially unacceptable".

The medicalization of infertility creates a framework in which individuals are encouraged to think of infertility quite negatively. In many cultures donor insemination is religiously and culturally prohibited, often meaning that less accessible "high tech" and expensive ARTs, like IVF, are the only solution.

An over-reliance on reproductive technologies in dealing with infertility prevents many – especially, for example, in the "infertility belt" of central and southern Africa – from dealing with many of the key causes of infertility treatable by artificial insemination techniques; namely preventable infections, dietary and lifestyle influences.

If good records are not kept, the offspring when grown up risk accidental incest.

Risk factors

The risk factors of artificial insemination are comparatively low to other forms of fertility treatment. The most prominent risk factor would be infection after the procedure, with other risk factors including a higher risk of having twins or triplets, and minor vaginal bleeding during the procedure.

Although these risk factors are minor and generally manageable, there is a significant knowledge gap between identity groups around risk factors for fertility treatments in general. For instance, it was found that LGBTQ+ individuals had "had significant knowledge gaps of risk factors associated with reproductive outcomes when compared to heterosexual female peers." Therefore, it is imperative that providers take extra care in educating their LGBTQ+ patients on potential risk factors of artificial insemination. The implications of this knowledge gap between LGTBQ+ individuals and their heterosexual counterparts are serious and worth noting. Lack of access to proper information and risk factors around procedures like these may dissuade someone from pursuing these procedures altogether. As a result, there will be less normalization of LGBTQ+ family making and reproduction, which only perpetuates this cycle of lack of information among LGBTQ+ folks.

Some countries restrict artificial insemination in a variety of ways. For example, some countries do not permit AI for single women, and other countries do not permit the use of donor sperm.

Europe

As of May 2013, the following European countries permit medically assisted AI for single women:

Law in the United States

History of Law Around Artificial Insemination

Artificial insemination used to be seen as adultery and was illegal until the 1960s when states started recognizing the child born from artificial insemination as legitimate. Once the children began to be recognized as legitimate, legal questions around who the parents of the child are, how to handle surrogacy, paternity rights, and eventually artificial insemination and LGBT+ parents began to arise. Prior to the use of artificial insemination, the legal parents of a child were the two people who conceived the child or the person who birthed the child and their legal spouse, but artificial insemination complicates the legal process of becoming a parent as well as who is the parent of the child. Deciding who the parents of the child are is the largest legal predicament around artificial insemination. However, questions around surrogacy and donor's rights also appear as a side question to determining the parent(s). Some major cases that deal with artificial insemination and parental rights are, K.M v E.G, Johnson v Calvert, Matter of Baby M, and In Re K.M.H.

When children are conceived the traditional way, there is little discrepancy around who the legal parents of the child are. However, because children conceived using artificial insemination may not be genetically related to one or more of their parents, who the legal parents of the child are can come into question. Prior to the passage of the Uniform Parentage Act in 1973, children conceived via artificial insemination were deemed as "illegitimate" children. The Uniform Parentage Act then recognized the children born from artificial insemination as legal and laid precedent for how the legal parents of the child were decided. However, this act applied only to the children of those married couples. It established that the person who birthed the child was the mother and the father would be the husband of the woman. In 2002, the Uniform Parentage Act, which is adopted individually on a state by state basis, was revised to address non married couples and states that an unmarried couple has the same rights to the child that a married couple would. This extended who has the right to be a parent to a man who would supposedly fill in the social role as a "father." There were now numerous ways to establish parental rights for both the mother and the father depending on if the child was born using a sperm donor or a surrogate. Currently, a revised version of the Uniform Parentage Act is starting to be passed in a few states that expands how parental relations can be determined. This bill includes expanding "father" to mean any person who would fill the role of a father, regardless of their gender and "mother" is expanded to anyone who gives birth to the child regardless of gender. In addition, this act would also change any language of "husband" or "wife" to "spouse."

Paternity rights

There is no federal law that applies to all fifty states when it comes to artificial insemination and paternity rights, but the Uniform Parentage Act is a model which many states have adopted. Under the 1973 UPA, married heterosexual couples making use of artificial insemination through a licensed physician could list the husband as the natural father of the child, rather than the sperm donor. Since then a revised version of the Act has been introduced, though to less widespread adoption

Generally paternity is not an issue when artificial insemination is between a married woman and an anonymous donor. Most states provide that anonymous donors' paternity claims are not recognized, and most sperm donation centers make use of contracts that require donors to sign away their paternity rights before they can participate. When the mother knows the donor, however, or engages in artificial insemination while unmarried, complications may arise. In cases of private sperm donation, paternity rights and responsibilities are often conferred onto sperm donors when: the donor and recipient did not comply with state laws regarding artificial insemination, the sperm donor and recipient know one another, or the donor had the intent of being a father to the child. When one or a number of these things is true, courts have at times found written agreements relinquishing parental rights to be unenforceable.

Opposition and criticism

Religious opposition

Some theologically buttressed arguments reject the moral validity of this practice, such as Pope John XXIII. However, according to a document of the USCCB, the intrauterine insemination (IUI) of "licitly obtained" (normal intercourse with a silastic sheath i.e. a perforated condom) but technologically prepared semen sample (washed, etc.) has been neither approved nor disapproved by Church authority and its moral validity remains under discussion. Some religious groups, such as the Catholic Church, and individuals have also criticized artificial insemination because acquiring sperm for the procedure is seen as "a form of adultery promoting the vice of masturbation."

Other morality-based opposition

There are critics of artificial insemination who voice concerns regarding the potential for AI to encourage eugenicist practices through selection of particular traits. The line of reasoning follows the history of artificial insemination in breeding livestock and other domesticated animals wherein preferred traits are encouraged through human-controlled selection.

Other animals

Artificial insemination is used for pets, livestock, endangered species, and animals in zoos or marine parks difficult to transport.

Reasons and techniques

It may be used for many reasons, including to allow a male to inseminate a much larger number of females, to allow the use of genetic material from males separated by distance or time, to overcome physical breeding difficulties, to control the paternity of offspring, to synchronize births, to avoid injury incurred during natural mating, and to avoid the need to keep a male at all (such as for small numbers of females or in species whose fertile males may be difficult to manage).

Artificial insemination is much more common than natural mating, as it allows several female animals to be impregnated from a single male. For instance, up to 30-40 female pigs can be impregnated from a single boar. Workers collect the semen by masturbating the boars, then insert it into the sows via a raised catheter known as a pork stork. Boars are still physically used to excite the females prior to insemination, but are prevented from actually mating.

Semen is collected, extended, then cooled or frozen. It can be used on-site or shipped to the female's location. If frozen, the small plastic tube holding the semen is referred to as a straw. To allow the sperm to remain viable during the time before and after it is frozen, the semen is mixed with a solution containing glycerol or other cryoprotectants. An extender is a solution that allows the semen from a donor to impregnate more females by making insemination possible with fewer sperm. Antibiotics, such as streptomycin, are sometimes added to the sperm to control some bacterial venereal diseases. Before the actual insemination, estrus may be induced through the use of progestogen and another hormone (usually PMSG or Prostaglandin F2α).

History

Artificial insemination tools brought from the USSR by Luis Thomasset in 1935 to work at Cambridge Laboratories and South America.

The first viviparous animal to be artificially fertilized was a dog. The experiment was conducted with success by the Italian Lazzaro Spallanzani in 1780. Another pioneer was the Russian Ilya Ivanov in 1899. In 1935, diluted semen from Suffolk sheep was flown from Cambridge in Britain to Kraków, Poland, as part of an international research project. The participants included Prawochenki (Poland), Milovanoff (USSR), Hammond and Walton (UK), and Thomasset (Uruguay).

Modern artificial insemination was pioneered by John O. Almquist of Pennsylvania State University. He improved breeding efficiency by the use of antibiotics (first proven with penicillin in 1946) to control bacterial growth, decreasing embryonic mortality, and increase fertility. This, and various new techniques for processing, freezing, and thawing of frozen semen significantly enhanced the practical utilization of artificial insemination in the livestock industry and earned him the 1981 Wolf Foundation Prize in Agriculture. Many techniques developed by him have since been applied to other species, including humans.

Species

Artificial insemination is used in many non-human animals, including sheep, horsescattle, pigs, dogs, pedigree animals generally, zoo animals, turkeys and creatures as tiny as honeybees and as massive as orcas (killer whales).

Artificial insemination of farm animals is common in the developed world, especially for breeding dairy cattle (75% of all inseminations). Swine are also bred using this method (up to 85% of all inseminations). It is an economical means for a livestock breeder to improve their herds utilizing males having desirable traits.

Although common with cattle and swine, artificial insemination is not as widely practiced in the breeding of horses. A small number of equine associations in North America accept only horses that have been conceived by "natural cover" or "natural service" – the actual physical mating of a mare to a stallion – the Jockey Club being the most notable of these, as no artificial insemination is allowed in Thoroughbred breeding. Other registries such as the AQHA and warmblood registries allow registration of foals created through artificial insemination, and the process is widely used allowing the breeding of mares to stallions not resident at the same facility – or even in the same country – through the use of transported frozen or cooled semen.

In modern species conservation, semen collection and artificial insemination are used also in birds. In 2013 scientist of the Justus-Liebig-University of Giessen, Germany, from the working group of Michael Lierz, Clinic for birds, reptiles, amphibians, and fish, developed a novel technique for semen collection and artificial insemination in parrots producing the world's first macaw by assisted reproduction.

Scientists working with captive orcas were able to pioneer the technique in the early 2000s, resulting in "the first successful conceptions, resulting in live offspring, using artificial insemination in any cetacean species". John Hargrove, a SeaWorld trainer, describes Kasatka as being the first orca to receive artificial insemination.

Violation of rights

Artificial insemination on animals has been criticised as a violation of animal rights, with animal rights advocates equating it with rape and arguing it constitutes institutionalized bestiality.[69][70] Artificial insemination of farm animals is condemned by animal rights campaigners such as People for the Ethical Treatment of Animals (PETA) and Joey Carbstrong, who identify the practice as a form of rape due to its sexual, involuntary and perceived painful nature. Animal rights organizations such as PETA and Mercy for Animals frequently write against the practice in their articles. Much of the meat production in the United States depends on artificial insemination, resulting in an explosive growth of the procedure over the past three decades. The state of Kansas makes no exceptions for artificial insemination under its bestiality law, thus making the procedure illegal.

Criteria for benefiting from artificial insemination according to the 2021 Bioethics Law

According to the 2021 Bioethics Law, the criteria that must be met to benefit from artificial insemination are as follows:
