Determination of blood serum levels of luteinizing hormone (LH) are used to detect the day of the midcycle surge. This information, collected over several menstrual cycles of numerous women, is used to derive mathematical expressions relating the day of the surge to the length of the cycle. The equations are subsequently employed to predict the most likely day of the LH surge, and hence the time of ovulation, solely from knowledge of the average length and variability of a woman's cycles, without the need for determinations of LH. A convenient table is provided for making this prediction.
测定血清促黄体生成素（LH）水平可用于检测月经周期中期的LH峰出现日。收集众多女性多个月经周期的此类信息，用于推导将LH峰出现日与月经周期长度相关联的数学表达式。随后，这些方程仅根据女性月经周期的平均长度和变异性知识，无需测定LH，就可用于预测LH峰最可能出现的日期，进而预测排卵时间。还提供了一个方便的表格用于进行这种预测。
