Do people with androgen insensitivity syndrome have a clitoris?
Androgen Insensitivity Syndrome (AIS): Complete AIS (CAIS) In CAIS, there are no visible clinical signs of androgen action and the subjects are born with normal female external genitalia, though the clitoris, labia minora, and labia majora may be underdeveloped.
Do people with androgen insensitivity produce sperm?
Some people with this condition may have undescended testes, in which one or both testicles are not able to descend completely by puberty. Because they do not have ovaries and may have issues with the development of the testes, many people with PAIS are infertile, because they produce no or very little sperm.
Are people with CAIS male?
Most individuals with CAIS are raised as females. They are born phenotypically female and usually have a heterosexual female gender identity; However, at least two case studies have reported male gender identity in individuals with CAIS.
Is Cais genetic?
Complete androgen insensitivity syndrome (CAIS) is a genetic condition in which a child is genetically male, but develops female sex characteristics. CAIS is a disorder of sex development (DSD). When an egg cell is fertilized by a sperm cell, each parent contributes a sex chromosome.
Is CAIS genetic?
Why are people with CAIS infertile?
Complete androgen insensitivity syndrome occurs when the body cannot use androgens at all. People with this form of the condition have the external sex characteristics of females, but do not have a uterus and therefore do not menstruate and are unable to conceive a child (infertile).
How common is androgen insensitivity?
Complete androgen insensitivity syndrome affects 2 to 5 per 100,000 people who are genetically male. Partial androgen insensitivity is thought to be at least as common as complete androgen insensitivity. Mild androgen insensitivity is much less common.
Do people with CAIS produce testosterone?

Who has androgen insensitivity syndrome?
Androgen insensitivity syndrome (AIS) is when a person who is genetically male (who has one X and one Y chromosome) is resistant to male hormones (called androgens). As a result, the person has some of the physical traits of a woman, but the genetic makeup of a man.
How does androgen insensitivity syndrome occur?
About two-thirds of all cases of androgen insensitivity syndrome are inherited from mothers who carry an altered copy of the AR gene on one of their two X chromosomes. The remaining cases result from a new mutation that can occur in the mother’s egg cell before the child is conceived or during early fetal development.
