The most important goal in the clinical evaluation of a patient with hirsutism is to rule out significant underlying disease. To do this, seek to understand the cause of hyperandrogenism, if this is present.

  • Excess androgens can be from either an exogenous or an endogenous source.

    • An exogenous source of androgens can usually be elicited by history findings; however, surreptitious androgen use has been reported in female athletes, especially those at a high level of competition.

    • Endogenous androgens originate from either the adrenal cortex or the ovary. Therefore, the evaluation of androgen excess can focus on disorders of these 2 glands. The principal possibilities are tumors of the ovary or the adrenal cortex, Cushing syndrome, CAH, and PCOS. Idiopathic hirsutism is the most common etiology, but it is a diagnosis of exclusion. Therefore, seek other causes first.
