[Relations between sperm findings and fertility prognosis in childless couples].

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.

[Catamnestic study about the fertility of the man (author's transl)].

Collective investigations of fertility in childless married couples were carried out in 9 andrological health centres of the GDR. Analysis of 1937 spermatograms in comparison to fertility after 1 to 2 years shows: (1) Fertility decreases significantly at sperm density nearly 10 million per ml. (2) Motility below 60 per cent caused reduced fertility. Normal motility is more important than normal density of spermatozoa. (3) Fructose level doesn't correlate to motility or fertility of man.
