Human seminal plasma is known to possess considerable proteolytic activity, much of which is associated with lysosomes. The activities of lysosomal hydrolases like alkaline proteinase, cathepsin-D, aryl-sulfatase and N-acetyl-beta-D-glucosaminidase in seminal plasma from randomly chosen infertile and vasectomised men have been compared. These enzymes have been implicated in the coagulation and liquefaction processes. The role of fructose and proteins in these processes has also been studied. The results indicate that cathepsin-D and aryl-sulfatase activity in infertile men were significantly lower than normo-spermic subjects. N-acetyl-beta-D-glucosaminidase was lowest in azoospermia suggesting that it could be used as a biochemical marker for azoospermia. Conversely, alkaline proteinase showed increased levels in all the infertile cases.
