Abstract
Acrosin is a protease in the mammalian sperm head, acrosome (Fritz et al., 1975) and its physiological role in the fertilization processes is thought to participate in the sperm penetration to ovum. This enzyme is classified as one of the serine protesses, such as trypsin and kallikreins (Fritz et ale, 1975). On the other hand, it has been reported that administrations of hog pancreatic kallikrein to male infertility patients, especially oligozoospermia and asthenozoospermia caused improvement of sperm counts and motility (Schill, 1977; Leidl, et al., 1974). Fritz et al. described that the kinin system enhances sperm motility, O2-consumption and fructolysis, in vitro (Schill, 1974).
