The ability of stored spermatozoa to penetrate fresh samples of cervical mucus obtained from 23 patients during 47 menstrual cycles was studied, utilizing an in vitro test. The determination of daily hormonal and gonadotropin values allowed an accurate realationship to be established between the results of sperm-mucus interaction and the environmental milieu. Cervical mucus was found to be effectively penetrable only on day -1 and day 0 when considered with respect to the plasma luteinizing hormone surge. Correlation was apparent between the ability of sperm to penetrate and the favorable clinical parameters of cervical assessment.
利用体外试验，研究了在47个月经周期中从23名患者获取的储存精子穿透新鲜宫颈黏液样本的能力。通过测定每日激素和促性腺激素值，得以在精子与黏液相互作用的结果和环境背景之间建立准确的关联。就血浆促黄体生成素高峰而言，发现宫颈黏液仅在第-1天和第0天能被有效穿透。精子穿透能力与宫颈评估的良好临床参数之间存在明显的相关性。
