In vitro penetration tests of human sperm into cervical mucus were introduced in order to study the interaction between sperm and cervical mucus. In the present study the correlation between sperm velocity and penetration value has been assessed. 197 semen samples were run in the in vitro penetration test using semen of different qualities and cervical mucus of good quality. No differences were found either between sperm velocity in cervical mucus (17.3 +/- 0.9 micrometers/s) and in semen (19.9 +/- 0.8 micrometers/s) or at different distances measured along the flat capillary tube (1, 2 and 3 cm). A highly significant correlation was found between sperm velocity and penetration value rates (p less than 0.0001, r = 0.9). Thus, sperm velocity in semen is a variable of great importance in the assessment of the quality of the ejaculate.
为研究精子与宫颈黏液之间的相互作用，开展了人精子穿透宫颈黏液的体外试验。在本研究中，评估了精子速度与穿透值之间的相关性。使用不同质量的精液和优质宫颈黏液，对197份精液样本进行了体外穿透试验。在宫颈黏液中的精子速度（17.3±0.9微米/秒）与精液中的精子速度（19.9±0.8微米/秒）之间，以及沿扁平毛细管在不同距离（1、2和3厘米）处测量时，均未发现差异。精子速度与穿透值率之间存在高度显著的相关性（p＜0.0001，r = 0.9）。因此，精液中的精子速度在评估射精质量方面是一个非常重要的变量。
