The investigation was designed to objectively determine the clinical usefulness of the fractional postcoital test. Forty-three normal subjects had midcycle cervical mucus collection at various times after insemination. There was a significant correlation between the number of motile sperm at the internal os level and the total sperm count within the cervical mucus. The median internal os count was 15 motile sperm per high-power field with a lower 95% confidence limit of five motile sperm per high-power field. Therefore, the fractional postcoital test is useful clinically as it is a physiologic indication of sperm transport in cervical mucus.
该研究旨在客观地确定性交后试验（分段）的临床实用性。43名正常受试者在授精后的不同时间收集了月经周期中期的宫颈黏液。宫颈内口水平的活动精子数量与宫颈黏液中的总精子数之间存在显著相关性。宫颈内口的活动精子数中位数为每高倍视野15个活动精子，95%置信下限为每高倍视野5个活动精子。因此，性交后试验（分段）在临床上是有用的，因为它是精子在宫颈黏液中运输的生理指标。
