Androgen insensitivity is a rare disorder that occurs when a person’s cells do not respond to male hormones (androgens) as they should. This means that the person has the genetic makeup of a male, but the body does not respond to male hormones normally. As a result, the body may not develop male characteristics and organs.
The exact prevalence of androgen insensitivity is not known, but it is estimated to affect 1 in every 20,000 to 64,000 individuals. These numbers may be higher, however, as many cases of androgen insensitivity are not diagnosed or reported. This is because the disorder does not always present with obvious symptoms.
Androgen insensitivity is also known as AIS, or androgen insensitivity syndrome. It is caused by a genetic mutation in the gene responsible for the androgen receptor. This mutation prevents the body from responding to androgens normally.
Androgen insensitivity is typically classified as either complete or partial. Complete androgen insensitivity is more severe and occurs when the body does not respond to any androgens at all. Partial androgen insensitivity occurs when the body only partially responds to androgens.
Although androgen insensitivity is a rare disorder, it is important that individuals receive the proper diagnosis and treatment. Treatment may include hormone replacement therapy, gender-affirming surgeries, and psychological support. With the right care, individuals with androgen insensitivity can live a full and fulfilling life.
