基础体温是在醒来后休息5分钟时用舌下插入的温度计测量的。许多女性认为这是早晨的例行负担;这可能会导致数据丢失，因为他们忘记测量，或者在测量过程中睡着的数据错误。为了克服这一点，一种名为Ran's night的可战设备被开发出来，用于在睡眠期间自动测量腹部皮肤温度。在这项研究中，我们检查了腹部皮肤温度检测排卵的诊断准确性相比，基础体温。通过在内衣之间放置一个可穿戴的衣服温度计，在睡眠期间自动测量腹部皮肤温度六小时。每天早上醒来时也测量BBT。如果连续三天的体温高于前六天，则认为已经排卵。采用尿LH测定排卵参考日。对45名健康妇女的202个周期进行检测，基础体温和腹部皮肤温度每周期检测一次温度变化的灵敏度分别为85.9%和80.1%。舌下温度与排卵参考日的偏差为0.2±2.5天，腹部皮肤温度与排卵参考日的偏差为0.4±2.7天，差异无显著性。此外，对于对应于同一时期的两者之间的差异，获得了强相关性（0.703）。这些结果表明，腹部皮肤温度可以用来估计排卵日期与基础体温相同的准确性。
Basal body temperature is measured at rest for 5 minutes after waking up with a thermometer inserted under the tongue. Many women perceive this as a morning routine burden; this may lead to missing data, because they forget to take measurements, or data errors from falling asleep during the measurments. To overcome this, a wararable device called Ran's night were developed to automatically measures abdominal skin temperature during sleep. In this study, we examined the diagnostic accuracy of abdominal skin temperature in detecting ovulation compared to basal body temperature. Abdominal skin temperatures were automatically measured for six hours during sleep by placing a wearable in-clothes thermometer between underwear. BBT were also measured upon waking each morning. If the body temperature on three consecutive days is higher than the last six days before, it is assumed that ovulation has occurred. The ovulation reference date was detected by LH urinalysis. For 202 cycles obtained from 45 healthy women, the sensitivity in detecting one temperature shift per cycle were 85.9% and 80.1% for basal body temperature and abdominal skin temperatures, respectively. The deviation from the ovulation reference date was 0.2±2.5 days for sublingual temperature and 0.4±2.7 days for abdominal skin temperature, with no significant difference. In addition, a strong correlation (0.703) was obtained for the difference between the two corresponding to the same period. These results indicate that abdominal skin temperature can be used to estimate the date of ovulation with the same accuracy as basal body temeperature.
