Abstract
The presence of estrogen deficiency associated with elevated gonadotropins usually signifies menopause. However, there have been a few case reports of ovulation and pregnancy despite hypergonadotropic hypogonadism. Described herein is a case of a perimenopausal woman who not only failed to ovulate in response to clomiphene citrate therapy but also failed to generate a level of serum estradiol (E2) over 30 pg/ml. Following pharmacologic suppression of her elevated gonadotropins with ethinyl estradiol, she spontaneously formed 3 mature follicles, and her serum E2 climbed to 868 pg/ml. This case suggests that some perimenopausal women may respond to their own endogenous elevated gonadotropins as if they are taking ovulation-inducing drugs and may, as a consequence, form multiple follicles.
