title: A modified technique of human in vitro fertilization and embryo transfer.
abstract: Forty-seven ovulatory women were treated with a modified technique of human in vitro fertilization and embryo transfer. All patients received clomiphene citrate, 150 mg per day, and follicle development was monitored by real-time ovarian ultrasound and serum estradiol measurement. In the 45 patients who underwent laparoscopy, eight patients were found to have a poor response to clomiphene citrate and were dropped from the treatment cycle. Four additional patients had an endogenous luteinizing hormone increase and did not undergo laparoscopy. Nine patients were found to have inaccessible ovaries at the time of laparoscopy. In patients with accessible ovaries, oocytes were recovered in all cases. Embryo transfers were performed in 72% of patients, and 19% of these transfers resulted in pregnancy. This technique of ovulation monitoring appears to increase oocyte recovery and fertilization rate and subsequent implantation success.
