人类精子穿透宫颈粘液的各种体外试验结果均颇相似。对不育夫妇的试验研究说明不孕症与精液标本中正常精子形态的比例有关。此外,试验结果不佳者,排精中尾部缺陷的精子明显多于结果正常的精液标本。通过女性生殖道精子移动到受精部位,宫颈粘液分泌是第一道屏障。弄清影响精子穿透宫颈粘液成功的因素是诊断不孕症一项十分重要的依据。精子活动力对穿透粘液极为重要,并可能也是在女性生殖道中选择正常精子形态的基础。在精液分析中,已知精子活动力和精子形态是正相关,而正常的精子形态与成功地穿透粘液有关。本报道的目的是研究精子形态参数和精子穿透
The results of various in vitro tests of human sperm penetrating cervical mucus are quite similar. Experimental studies of infertile couples show infertility and the proportion of normal sperm morphology in semen samples. In addition, the poor test results, the tail sperm defect tail sperm were significantly more than normal results of semen samples. Through the female reproductive tract sperm to fertilization site, cervical mucus secretion is the first barrier. To understand the factors that affect the success of sperm penetration of cervical mucus is to diagnose infertility is a very important basis. Sperm motility is extremely important for penetrating mucus and may also be the basis for selecting normal sperm morphology in the female genital tract. In semen analysis, it is known that sperm motility and sperm morphology are positively correlated, while normal sperm morphology is associated with successfully penetrating mucus. The purpose of this report is to study sperm morphology parameters and sperm penetration
