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.
27例患者接受了自然周期的超声检查和临床监测，以便能适时给予人绒毛膜促性腺激素，从而尝试在最佳的取卵时间安排筛查性腹腔镜检查。在26例腹腔镜检查中，仅有2例出现卵巢暴露不充分的情况。在预定的腹腔镜检查时，7例患者已排卵。共获得9个成熟卵母细胞、7个未成熟卵母细胞和3个排卵后卵母细胞，并完成了7次胚胎移植。每次腹腔镜检查获得的卵子数为0.73个。控制排卵时间的尝试不可预测，获得的成熟卵母细胞很少，该 procedure对患者几乎没有最终益处。 （注：原文中“procedure”未明确具体所指，根据语境推测为腹腔镜检查相关流程，这里保留英文未翻译）
