摘要
３０对不育夫妇，在预计排卵日性交后４～１０小时，检查宫颈粘液中精子活力和形态，并与精液中对应参数比较，以探讨ＰＣＴ的方法、宫颈粘液对精子的选择机理及影响ＰＣＴ的因素。结果表明，粘液中精子活力和正常形态较精液中对应参数有显著提高，提示宫颈粘液通过阻止活力差的精子从而选择活力强、形态正常精子进入宫腔。文章认为限制、影响ＰＣＴ的因素众多，主要包括精液和宫颈粘液质量、ＰＣＴ时间及取样镜检时间等。并强调了掌握好试验方法的重要性。
A comparison of the morphology and motility of sperm bathed in the cervical mucus and in the seminal fluid was undertaken in 30 infertile couples 4￣10 hours after sexual intercourse on the anticipated date of ovulation at an aim to study technique of PCT, the sperm selection mechanisms of the cervical mucus and factors of the effect on PCT.Results were as follows:The morphology and motility of sperm in the cervicalmucus were significantly increase as compared with those in the seminal fluid.It issuggested that the cervical mucus is capable to select normal morphology sperm with high motility by restricting the penetration of poor motility sperm. The authors believed that the factors of restriction and affection on PCT were miscellaneous,whereas these factors mainly include quality of seminal fluid and cervical mucus,the hour of PCT and examination of cervical mucus after sexual intercorse.The paper also laid stress on the importance of mastering the PCT method.
