title: [Effect of anti-fibronectin-serum on fertilization capacity of human spermatozoa].
abstract: Using the in vitro penetration test, we initially studied effects of anti-fibronectin (FN)-serum on fertilization capacity of human spermatozoa. Owing to the coincubation of anti-FN-serum in a heterologous system (human spermatozoa and zona-free gold hamster oocyte), a certain increase was found in the penetration rate at a low concentration of anti-FN-serum. The penetration rate in the treated group was 20% higher than that in the control group at an anti-FN-serum concentration of 10 microliters/ml (P < 0.05), but at a higher concentration of anti-FN-serum, the penetration rate was not affected. The results suggest that anti-FN-serum can improve the fertilization capacity of human spermatozoa, help to treat the unexplained infertility, and increase the repregnancy rate of vasovasotomy.
