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.
