[Oral kallikrein-therapy of asthenozoospermia].

Over a period of 7 weeks 51 men with idiopathic asthenozoospermia were treated with Kallikrein (600 Kallikrein units per day). A statistically significant improvement of sperm motility was observed with a maximum 1 month after the therapy. The conception rate was 31%. Stimulation of sperm motility may be caused by a positive effect on spermatogenesis, by an improvement of the nutritional functions of the tubulus apparatus and by an improvement of sperm maturation in the eqididymis.
