[The diagnosis of male infertility based on the lysozyme level in sperm]

Spermal samples of 60 men were examined, 40 of these men suffering from sterility. A significant reduction of the share of mobile spermatozoa in sterile patients was parallelled by a reduced spermal lysozyme level, as against that in healthy controls. In other words, a relationship between spermal lysozyme level and spermatozoa mobility was revealed. The detected regular reduction of spermal lysozyme level permits using this parameter as a diagnostic test.
