Retrospective review of cervicovaginal (Pap) smears of women with known sexual histories affords an opportunity to assess the potential for postcoital sperm recovery for large numbers of individuals. This study reviewed 542 individuals' Pap smears with accompanying sexual histories. Three hundred forty-nine respondents reported at least one act of sexual intercourse during the five days preceding the Pap smear. Unlike a previous report, the current study showed very poor sperm recovery (maximum of 25% during the first postcoital day). The observed results roughly correlate with the incidence of sperm noted on screening of large numbers of routine clinical Pap smears in a private reference laboratory. Routine Pap smears can detect sperm but do not appear to be an ideal method to substantiate recent sexual intercourse.
对有已知性史女性的宫颈阴道（巴氏）涂片进行回顾性分析，为评估大量个体性交后精子恢复的可能性提供了契机。本研究回顾了542名个体的巴氏涂片及相应性史。349名受访者报告在巴氏涂片检查前五天内至少有一次性交。与之前的一份报告不同，本研究显示精子恢复情况很差（性交后第一天最多为25%）。观察结果与在一家私立参考实验室对大量常规临床巴氏涂片筛查中发现的精子发生率大致相关。常规巴氏涂片可检测到精子，但似乎并非证实近期性交的理想方法。
