目的　探讨轻度子宫内膜异位症患者腹腔液对精子功能的影响。方法　采用去透明带地鼠卵穿透试验为检测方法，以精子穿卵率及受精卵外精子附着数为指标，子宫内膜异位症组（２５ 例） 及正常对照组（１５ 例） 在腹腔镜直视下收集腹腔液，将正常人精液按１∶１ 的比例稀释，观察腹腔液对精子穿卵的影响。结果　子宫内膜异位症组精子穿卵率及受精卵外精子附着数明显低于正常对照组，两组之间有显著性差异（ Ｐ＜ ０．０５） 。结论　轻度子宫内膜异位症腹腔液对精子功能有影响 Objective To investigate the effect of peritoneal fluid on sperm function in patients with mild endometriosis. Methods The method of transdermal zygotic egg penetration test was used to detect the rate of egg penetration and the number of spermatozoa attached to the egg. The endometriosis group (25 cases) and the normal control group (15 cases) Peritoneal fluid was collected under laparoscopy and the normal human semen was diluted 1: 1 to observe the effect of peritoneal fluid on sperm penetration. Results The rate of sperm penetration and the number of sperm oocyte attachment in endometriosis group were significantly lower than those in normal control group (P <0.05). Conclusion Peritoneal fluid of mild endometriosis has an influence on sperm function
