This indicates about inhibition of arginase pathway of L-arginine metabolism, which is not significantly dependent on the type of disruption of spermatogenesis. The most significant changes have been observed in infertile men with leucocytospermia since white blood cells stimulate the formation of reactive oxygen species, induction and development of oxidative and nitrative stress in spermatozoa. Inhibition of arginase pathway of L-arginine metabolism has adaptive role, which is to limit bioavailabil- ity of L-arginine and to prevent excessive formation of NO in cytotoxic concentrations to sperm cells. It has been noted changes in serum concentrations of gonadotropin and sex hormones in men with various forms of pathospermia.
