Until now, a comprehensive andrologic examination is not capable of finding out the reason of pathospermia in 40–72 % of cases of male infertility and, as a result, of assigning the appropriate etiotropic treatment. A comparative dynamic study of spermograms of 107 patients with idiopathic pathozoospermia depending on various types of treatment has been held immediately, 1 month, and 2 months after completion of the therapy course. It has been determined that significantly greater and sustained improvement in quality and quantity of ejaculate is achieved in 1 month as compared to monotherapy with L-carnitine in combination with hyperbaric oxygenation by eliminating the effects of hypoxia and oxidativestress, and the effect is maintained during the whole term of observation
