A direct action of kallikrein on spermatozoal motility?
Semen samples from infertile normozoospermic and slight to moderate asthenozoospermic subjects were tested in parallel with and without kallikrein (dry substance) by Kremer's capillary tube test. Penetration in human midcycle cervical mucus and AB Rh+ (RH+) serum was evaluated. Kallikrein increased spermatozoal penetration into cervical mucus after 3 hrs incubation (p less than 0.01 in normozoospermic subjects).
