Abstract

Midcycle bovine cervical mucus (BCM), fresh (FBCM) or frozen at -20 degrees C (BCMF), and human cervical mucus (HCM) were collected and tested in in vitro penetration tests, using human ejaculated spermatozoa of good quality. Penetration tests were performed at 34 degrees C for 1 hour, and the penetration value (PV) was calculated. Duplicates of each run were in a narrow deviation. Correlations between PV rates of the same semen samples in the 3 sources were found to be significantly high (HCM versus FBCM, r = 0.958; HCM versus BCMF, r = 0.982, and FBCM versus BCMF, r = 0.985), suggesting that human ejaculated spermatozoa penetrate the cervical mucus of all three sources at the same rate.

摘要

收集处于月经周期中期的牛宫颈黏液（BCM），分为新鲜的（FBCM）和在-20℃冷冻的（BCMF），以及人宫颈黏液（HCM），并使用质量良好的人类射出精子进行体外穿透试验。在34℃下进行1小时的穿透试验，并计算穿透值（PV）。每次试验的重复结果偏差很小。发现在3种来源中，同一精液样本的PV率之间存在显著的高度相关性（HCM与FBCM相比，r = 0.958；HCM与BCMF相比，r = 0.982；FBCM与BCMF相比，r = 0.985），这表明人类射出精子以相同速率穿透所有三种来源的宫颈黏液。
