Regression of Polycystic Ovaries by Estrogen Therapy.

Adolescent girls and single women with progressive hirsutism due to polycystic ovaries present a therapeutic dilemma. Clomiphene citrate is useful only to induce ovulation and has no beneficial effect on hirsutism. Surgical wedge resection of these ovaries usually arrests progression of hirsutism and restores ovulatory menses. Such treatment, however, is best reserved until such time as pregnancy would be an equal objective. Treatment of 5 patients by hypothalamic-pituitary-ovarian suppression with 100-mg estradiol pellets implanted subcutaneously every 6 months reduced ovarian size in all 5 patients and halted the progression of hirsutism.
