The interaction between human spermatozoa and cervical mucus was studied during 14 cycles of artificial insemination (AI) with a cervical cup. The concentration of spermatozoa in the inseminate was determined as were the percentage of motility, mean swimming speed, and sperm morphology. The percentage of motility, swimming speed, and morphology of spermatozoa in the mucus were determined at 1 hour and 48 hours after AI. The percentage of motile sperm was always higher in the cervical mucus than in the semen. In some cases, spermatozoa appeared to swim faster in the mucus than in the semen but in other cases the reverse was true. In all 14 cases some spermatozoa could be found in the mucus at 48 hours after AI. In general, the percentage of motility and swimming speeds of the cervical sperm remained unchanged over the 48-hour study interval. The percentage of spermatozoa with normal morphology was higher in the cervical mucus than in the semen. The alteration in the composition of the sperm population appeared to result from exclusion by the mucus of most classes of abnormal sperm. The morphology of the cervical sperm population was similar at 1 hour and at 48 hours after AI.
在14个使用宫颈帽进行人工授精(AI)的周期中,对人类精子与宫颈黏液之间的相互作用进行了研究。测定了授精液中精子的浓度、活力百分比、平均游动速度和精子形态。在人工授精后1小时和48小时测定黏液中精子的活力百分比、游动速度和形态。宫颈黏液中活动精子的百分比总是高于精液中的。在某些情况下,精子在黏液中的游动速度似乎比在精液中快,但在其他情况下则相反。在所有14个案例中,人工授精后48小时在黏液中都能发现一些精子。总体而言,在48小时的研究期间,宫颈精子的活力百分比和游动速度保持不变。宫颈黏液中形态正常的精子百分比高于精液中的。精子群体组成的改变似乎是由于黏液排除了大多数类型的异常精子所致。人工授精后1小时和48小时宫颈精子群体的形态相似。
