Human seminal fibrinolytic activity: specific determinations of tissue plasminogen activator and urokinase.
The determination of total fibrinolytic activity of ejaculates was realized by fibrin plate method. For the same seminal samples, tissue plasminogen activator (t-PA), urinary plasminogen activator (uPA) antigens and uPA activity were specifically quantified. The seminal values were fifty times higher than in the blood for t-PA and fifteen times for uPA. There was no correlation between the both levels but from split ejaculates measurements a higher concentration was observed in all first fractions. By zymography assays, it was shown that seminal plasminogen activators are under active forms. The lack of proUrokinase in semen was also demonstrated.
