Occurrence of ovulation was detected by laparoscopy between 22 and 47 hours following the onset of the luteinizing hormone (LH) surge in plasma (61 patients) or human chorionic gonadotropin (hCG) administration (76 patients). None of 22 patients had ovulated before the 34th hour following LH surge or hCG, as compared with 3.4% (3 of 89) and 50.0% (11 of 22) laparoscoped after 34 to 37 hours or 37 to 39 hours, respectively. Whether measured with respect to the initial rise of LH or the injection of hCG, the time lapse before ovulation was comparable. Ovulation was more frequently established at 37 to 39 hours in spontaneous cycles (10/13) than in clomiphene-treated cycles (1/9, P less than 0.01). The onset of the LH rise was found to be a more accurate criterion than the LH peak in determining the time of ovulation.
通过腹腔镜检查发现，在血浆中促黄体生成素（LH）激增开始后的22至47小时之间（61例患者）或注射人绒毛膜促性腺激素（hCG）后（76例患者）出现排卵。在LH激增或注射hCG后的第34小时之前，22例患者均未排卵，相比之下，在34至37小时或37至39小时后进行腹腔镜检查的患者中，分别有3.4%（89例中的3例）和50.0%（22例中的11例）排卵。无论以LH的初始升高还是hCG注射来衡量，排卵前的时间间隔是相当的。在自然周期中，排卵更频繁地发生在37至39小时（10/13），而在克罗米芬治疗的周期中则较少（1/9，P<0.01）。发现在确定排卵时间方面，LH升高的开始比LH峰值是更准确的标准。
