A new method for estimating the day of ovulation was assessed. The method is as follows; The range of hypothermic phase presumed 0.1 degrees C around mean basal body temperature of early 10 menstrual days. The day of ovulation was estimated by searching for the day which is followed by at least 4 consecutive days of rising temperature within the range of hypothermic phase. The accuracy of this method was assessed by comparing the basal body temperature and urinary luteinizing hormone (LH) peak day. The estimated day fell within 2 days during which the ovulation will occur most probably in 36 cycles (69%) and fell within 4 days around most expectable ovulation time in 46 cycles (88%). This result provide some insight into the limitation of the basal body temperature which is influenced by factors other than progesterone in determining the time of ovulation. But our simple objective method is useful in some cases than any other method determined by vague criteria.
一种估算排卵日的新方法得到了评估。该方法如下：假定低温期范围在月经周期前10天平均基础体温上下0.1摄氏度。通过在低温期范围内寻找随后至少有4天体温连续上升的日期来估算排卵日。通过比较基础体温和尿促黄体生成素（LH）峰值日来评估该方法的准确性。在36个周期中（69%），估算日期落在排卵最可能发生的2天内，在46个周期中（88%），估算日期落在最预期排卵时间的4天内。该结果为基础体温在确定排卵时间时受孕酮以外因素影响的局限性提供了一些见解。但我们这种简单客观的方法在某些情况下比任何由模糊标准确定的其他方法都更有用。
