Improvement of sperm motility was found to exist for at least 3 months following termination of the 7 week duration kallikrein treatment. Additionally, a significant increase in the number of spermatozoa was observed 3 and 5 months after starting parenteral application of kallikrein.}, keywords = {Administration, Oral, Humans, Infertility, Male, Injections, Kallikreins, Male, Sperm Motility, Stimulation, Chemical}, issn = {0020-725X}, author = {Schill, W B} }
