Complete androgen insensitivity syndrome



Complete androgen insensitivity syndrome is a condition that affects sexual development before birth and during puberty. People with this condition are genetically male (one X and one Y chromosome) but do not respond to male hormones at all. As a result, they generally have normal female external genitalia and female breasts. However, they do not have a uterus or cervix so are unable to menstruate or conceive children. Other signs and symptoms may include undescended testes and sparse to absent pubic hair. Gender identity is typically female. Complete androgen insensitivity syndrome is caused by changes (mutations) in the AR gene and is inherited in an X-linked manner. Treatment and gender assignment can be a very complex issue, and must be individualized with each affected person. In general, surgery may be required to remove testes that are located in unusual places and estrogen replacement therapy can be prescribed after puberty.[1][2][3]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
