Treatment of men with oligoasthenozoospermia and asthenozoospermia with kallikrein

Abstract A randomised group of 75 men with idiopathic oligoasthenozoospermia and asthenozoospermia were subjected to control study with kallikrein. Kallikrein was given to 45 men 600 units daily in a period of 3-6 months. The other group of 30 infertile men was followed during the same period of time. Percentage of motile sperm was significantly improved after 3-6 months treatment with kallikrein. Sperm count and percentage of morphologically normal sperm showed improvement but was not statistically significant. Infertile men with sperm count below 20 X 10(6)/ml had greater improvement in sperm count than men with sperm count over 20 X 10(6)/ml. This study emphasizes that kallikrein is a relatively good drug for restoring sperm motility in idiopathic oligoasthenozoospermia and asthenozoospermia.
