Description

Androgen insensitivity syndrome (AIS) is a genetic disorder that affects the development of the reproductive system in people with XY chromosomes. People with AIS are born with male chromosomes, but their bodies are unable to respond to androgens, the hormones responsible for male sexual development. As a result, they may have female external genitalia, and may be raised as girls. AIS is caused by mutations in the androgen receptor gene, which prevents the body from responding to androgens. Treatment for AIS typically involves hormone replacement therapy and surgery to correct any physical differences.
