Twenty-five cycles induced by human menopausal gonadotropin (hMG) were serially studied by ultrasound. The developing follicles were observed up to and beyond human chorionic gonadotropin (hCG) administration. Ovulation as determined by subsequent pregnancy or a sustained elevation of basal temperature was seen in 18 of these cycles. Among these patients the follicular size ranged between 24 and 13 millimeters. No pregnancies occurred where the follicular size was below 15 mm. A shortened luteal phase was noted in three cycles where the follicular size was either 13 or 14 mm. Multiple follicles greater than 10 mm were observed in 14 of the ovulating cycles, but in no case did a multiple pregnancy occur. Fifteen millimeters is therefore suggested as a minimum size for satisfactory ovulation, but it does not appear that an optimum size exists. We conclude that ultrasound can play an important role in the monitoring of ovulation induction but does not replace the present methods.
通过超声对25个由人绝经期促性腺激素（hMG）诱导的周期进行了连续研究。对发育中的卵泡进行观察，直至并超过人绒毛膜促性腺激素（hCG）给药时间。在这些周期中有18个周期通过后续妊娠或基础体温持续升高确定发生了排卵。在这些患者中，卵泡大小在24至13毫米之间。卵泡大小低于15毫米时未发生妊娠。在卵泡大小为13或14毫米的3个周期中观察到黄体期缩短。在14个排卵周期中观察到多个大于10毫米的卵泡，但无一例发生多胎妊娠。因此，建议将15毫米作为实现满意排卵的最小卵泡大小，但似乎不存在最佳大小。我们得出结论，超声在监测排卵诱导中可发挥重要作用，但不能取代现有方法。
