Types of Intersex

5α-Reductase deficiency is an autosomal recessive intersex condition caused by a mutation of the 5α reductase type II gene.

Androgen Insensitivity Syndrome, or AIS, is a genetic condition, inherited (except for occasional spontaneous mutations), occurring in approximately 1 in 20,000 individuals. In an individual with complete AIS, the body’s cells are unable to respond to androgen, or “male” hormones.

What is intersex? How common is intersex? Intersex conditions. How do I know if I have an intersex condition? 5-alpha reductase deficiency; Androgen Insensitivity Syndrome (AIS)

Clitoromegaly means that the clitoris is larger than expected. This is a description, rather than a diagnosis. The most common cause of clitoromegaly is probably CAH

Congenital Adrenal Hyperplasia (CAH) is the most prevalent cause of intersex among people with XX chromosomes. About 1 in 10,000 to 18,000 children are born with congenital adrenal hyperplasia, but it does not cause intersex in those with XY chromosomes, so the prevalence of CAH-related intersex is about 1 in 20,000 to 1 in 36,000.
