title: Hyperandrogenism: new insights into etiology, diagnosis, and therapy.
abstract: Mutations in the genes for the insulin receptor, 21-hydroxylase, 11 beta-hydroxylase, and 3 beta-hydroxysteroid dehydrogenase isomerase enzymes are associated with hyperandrogenism. These genetic causes of hyperandrogenism account for less than 10% of all cases. A major goal of future research will be to identify other genetic causes of hyperandrogenism. Evidence continues to accumulate that luteinizing hormone, insulin-like growth factor I, and insulin are major factors regulating ovarian androgen production. Optimal therapy for hyperandrogenism probably includes simultaneous suppression of androgen production and blockade of androgen action.
