Hirsutisme: que faire [Hirsutism, what can be done?]

Hirsutism is a relatively frequent condition in an ambulatory setting affecting about 4% of women. A rational clinical and biochemical diagnostic approach assures an optimal treatment directed at etiologic and pathogenetic factors. The diagnosis of hyperandrogenism is evaluated considering the pathophysiologic mechanisms responsible for excessive growth of hair. Ovarian and adrenal tumors are the most serious diseases that have to be excluded by clinical and biochemical tests. The other causes for hirsutism are treatable by a great variety of modalities, available drugs can inhibit pituitary gonadotropins, the hypothalamo-pituitary axis and the conversion of testosterone into biologically active substrate. Finally the binding of androgens to its receptor can be blocked. These possibilities for treatment and their indications for the different etiologies of hirsutism are discussed.
