Summary
This natural history study aims to gather information from up to 3,000 people with genetic conditions that cause too much androgen (male-like hormones), such as congenital adrenal hyperplasia (CAH) and familial male-limited precocious puberty (FMPP). Participants undergo various tests including blood work, glucose tolerance tests, imaging, and cognitive assessments to better understand how excess androgen affects growth, fertility, mood, and overall health. The study does not test any new treatment but will help doctors learn more about these conditions.
