title: Effect of high dose oral Kallikrein treatment in men with idiopathic subfertility: evaluation by means of in vitro penetration test of zona free hamster ova.
abstract: High dose oral Kallikrein treatment (600 U Padutine per day) was given to 10 infertile men with poor semen quality. After 3 months of this treatment no pregnancies occurred, and no significant changes in routine semen characteristics were observed. Moreover, the capacity of the spermatozoa to migrate in vitro and to penetrate zona free hamster ova remained unchanged after Kallikrein ingestion. It is concluded that Kallikrein treatment was ineffective in these men.
