Two plasminogen activators, streptokinase and urokinase, stimulate human sperm motility.
The stimulatory effects of two plasminogen activators, namely streptokinase and urokinase, were measured with a trans-membrane migration method. Both drugs induced maximal motility increase at a concentration of 200 international unit/ml; the amplitude of maximal motility increase ranged from 17% to 19% of control. Although their stimulatory effects were much less than those of calcium regulating agents, the clinical application of these two drugs for improving the successful rate of artificial insemination deserves further investigation because the action site is seminal plasma rather than sperm.
