title: [Action of different components of the kallikrein kinin-system on sperm motility in vitro (author's transl)].
abstract: In vitro experiments with human semen showed a significant increase of quantitative and qualitative sperm motility after addition of kallikrein at concentrations of 1 KU/ml. Stimulation of sperm motility was further increased and extended by addition of human serum as a source of kininogen. Kinins added directly also showed enhancement of sperm motility. In contrast, carboxypeptidase B, a kininase, significantly reduced sperm motility. The physiological and therapeutical aspects of these results are discussed.
