Androgen Excess Society

Androgen-related disorders affect 6-8% of women of reproductive age, affecting 3.7 - 4.9 million in the US, and 89 - 119 million women worldwide.
70-90% of androgen excess is due to polycystic ovary syndrome (PCOS) with non-classic (late onset) adrenal hyperplasia, androgen secreting tumors, and syndromes of severe insulin resistance affecting the remainder.
Idiopathic hirsutism, although not strictly a disorder of androgen excess, affects approximately 5-15% of women depending on definition.
Patients who have PCOS are at higher risk for having insulin resistance, and for developing type II diabetes mellitus and possible cardiovascular disease.
Non-classic adrenal hyperplasia due to 21-hydroxylase deficiency affects between 1-8% of androgen excess women, and is one of the most common autosomal recessive disorders of man.
Hirsutism, the presence of excessive terminal hair growth in a male pattern in women, is one of the most common clinical signs of androgen excess depending on ethnicity.
Other signs of androgen excess include irregular ovulation or menstruation, infertility, oily skin, acne and scalp hair loss.
