What is the best approach to the evaluation of hirsutism?

Abstract

The evaluation of hirsutism should begin with a history and physical examination to identify signs and symptoms suggestive of diseases such as polycystic ovarian syndrome (PCOS), hypothyroidism, hyperprolactinemia, hyperandrogenic insulin-resistant acanthosis nigricans (HAIR-AN) syndrome, androgenic tumors, Cushing's syndrome, or congenital adrenal hyperplasia (CAH). Findings suggestive of these diseases include rapid or early-onset hirsutism, menstrual irregularities, hypertension, severe hirsutism, virilization, or pelvic masses (strength of recommendation [SOR]: B, based on a cohort study in a referral population). Hirsutism with unremarkable history and physical exam findings should be evaluated with a serum total testosterone and dehydroepiandrosterone sulfate (DHEAS) level (SOR: B, based on a cohort study in a referral population).
