In eight andrological centres more than 2,000 childless married men were examined catamnestically. Fertility was compared with the findings of the routine spermatograms. Conception rate is reduced significantly if sperm density is below 10 million, in motility of spermatozoa under 50% and in ejaculates with less than 60% normal-shaped spermatozoa. However, lower values of spermatozoa must not be compared with absolute infertility.
在8个男科中心,对2000多名不育已婚男性进行了随访检查。将生育能力与常规精子图的检查结果进行了比较。如果精子密度低于1000万、精子活力低于50%以及正常形态精子低于60%的射精量,则受孕率会显著降低。然而,精子数量较低的值不能与绝对不育相提并论。
