Combined screening laparoscopy and timed follicle aspiration for human in vitro fertilization

Twenty-seven patients underwent ultrasonographic and clinical monitoring of a spontaneous cycle so that human chorionic gonadotropin administration could be timed in an attempt to schedule the screening laparoscopy at the optimal time for oocyte aspiration. Inadequate ovarian access was encountered in only 2 of 26 laparoscopies. Seven patients had ovulated by the time of scheduled laparoscopy. Nine mature, seven immature, and three postovulatory oocytes were obtained, and seven embryo transfers were accomplished. The number of eggs obtained per laparoscopy was 0.73. The attempt to control the time of ovulation was unpredictable, few mature oocytes were obtained, and the procedure offered little ultimate benefit to the patient.
