[Incidence of hyperandrogenemia].

Within two years 341 amenorrheic patients treated in our endocrinological outpatient department were listed up retrospectively in WHO-classification groups. In 30 patients a primary amenorrhea and in 311 patients a secondary amenorrhea could be registered. In 28.3% a hypothalamic pituitary disorder must be diagnosed, in 5.1% a hypergonadotropic profile was observed. Uterine amenorrhea was seen in 0.6%, a hyperprolactinemia in 6.1%. The hyperandrogenemia with an incidence of 42.1% is remarkable and should be included in the WHO-classification.
