Ovarian follicular growth during the periovulatory period was measured using real-time ultrasound in 33 patients during 53 spontaneous ovulatory cycles. The mean follicular diameter increased from 14.1 mm four days before ovulation to a maximum of 20.1 mm on the day of presumptive ovulation. The results correspond with previous static ultrasound studies of follicular development and in nine cycles in which both methods were employed the correlation between measurements on the same day was highly significant (r = 0.944; p < 0.001). The day of ovulation could not be anticipated from a single measurement because of the relatively wide range of follicular size. Except in some obese subjects, real-time ultrasound examination of the developing follicle appears to be a useful technique for assessing the progress of the ovarian cycle.
在53个自然排卵周期中，对33例患者使用实时超声测量了围排卵期的卵泡生长情况。卵泡平均直径从排卵前4天的14.1毫米增加到推测排卵日的最大20.1毫米。这些结果与先前关于卵泡发育的静态超声研究一致，并且在9个同时采用两种方法的周期中，同一天测量结果之间的相关性非常显著（r = 0.944；p < 0.001）。由于卵泡大小范围相对较宽，无法通过单次测量预测排卵日。除了一些肥胖患者外，对发育卵泡进行实时超声检查似乎是评估卵巢周期进展的一种有用技术。
