Gamma-glutamyltranspeptidase and beta-glucuronidase in human ejaculates. Relation with abnormal liquefaction

Gamma-glutamyltranspeptidase (GGTP) and beta-glucuronidase activity were measured with commercial kits in 104 ejaculates. The two enzyme activities showed a positive correlation and GGTP activity was significantly correlated with sperm number and citrate concentration. GGTP activity is probably from prostatic origin. Ejaculates with abnormal liquefaction had a lower mean GGTP activity compared with ejaculates which showed normal liquefaction. In contrast beta-glucuronidase activity did not show such a difference.
