Investigative strategy of hyperandrogenism in women.

Investigative procedures in the assessment of female hyperandrogenism are reviewed. Based on their experience, the authors suggest an inexpensive investigative strategy in hyperandrogenic females consisting of the following: the first step depends upon the clinical symptoms--in cases of hirsutism with regular menstrual cycles, plasma testosterone (T) and plasma dehydroepiandrosterone sulfate (DHA-S) are assayed, and the basal body temperature chart is recorded. In cases of hirsutism with irregular or anovulatory menstrual cycles, in addition to T and DHA-S, plasma 17-hydroxyprogesterone and urinary-free cortisol are assayed. In case of anovulation without hirsutism, T and DHA-S are assayed, and the LHRH test is performed. The results of this first investigation allow to attribute to the woman one of the six following hormone profiles: (1) metabolic hyperadrenalism; (2) tumoral hyperandrogenism; (3) 21-hydroxylase defect; (4) nontumoral DHA-S increase; (5) nontumoral ovarian hyperandrogenism; (6) idiopathic hirsutism. The additional investigative procedures required in each of these groups are detailed.
