Hyperandrogenism or hyperandrogenemia are medical conditions characterized by excessive levels of androgens in the periphery or systemically. Clinical manifestations of hyperandrogenism include hirsutism, seborrhea, acne, androgenetic alopecia, and virilization. Hirsutism, defined as excessive growth of terminal hair in women in a male-like pattern, is the most commonly used clinical diagnostic criterion of hyperandrogenism and is determined by using a standardized scoring system of hair growth. Acne and alopecia are further common androgenic skin changes and might be observed without hirsutism in some women. Clitoris hypertrophy, increase of muscle mass, irregular menstrual cycle, and metabolic syndrome can also accompany this condition. Among others polycystic ovary syndrome (PCOS), Cushing disease, and late-onset adrenogenital syndrome belong to the most frequent causes of hyperandrogenemia. Virilization is a relatively uncommon feature of hyperandrogenemia and its presence often suggests an androgen-producing tumor. Management of symptoms include the use of antiandrogens such as cyproterone acetate, spironolactone, and flutamide. A thorough history, a focused clinical examination and an interdisciplinary approach together with gynecologists and endocrinologists are extremely helpful in the diagnostic evaluation and therapy of patients with suspected hyperandrogenism.
