title: High-dose human menopausal gonadotropin therapy for successful ovulation induction for in vitro fertilization in perimenopausal women.
abstract: Five women with elevated gonadotropin levels were treated with high doses of human menopausal gonadotropin (hMG) in order to induce an ovulatory response. Three of the five patients did not show any increase in circulating estradiol levels nor any change in the size of follicles (as observed by ultrasound), even after prolonged stimulation with up to 1200 IU of hMG. Two patients achieved an ovulatory response, however. They underwent laparoscopy with successful oocyte retrieval and fertilization. Both patients had evidence of pregnancy: one showed a transient hCG rise (chemical pregnancy), while the other continued to 12 weeks' gestational age when fetal demise was diagnosed.
