[The effect of highly purified swine pancreatic kallikrein on sperm motility after cryopreservation].
The effect of kallikrein on sperm motility in cryopreserved ejaculates was investigated. The study was productive of the following results: 1. Cryopreservation of ejaculates is followed by a significant loss of sperm motility. 2. Kallikrein is not effective when added to the ejaculates before cryopreservation. 3. Incubation of cryopreserved ejaculates with kallikrein (5 KU) and serum after thawing significantly inhibits the loss of motility due to cryopreservation in case the initial motility is normal or moderately reduced. Kallikrein is ineffective on sperm motility in ejaculates with low initial sperm motility.
