title: Enzyme activity of human ejaculates, relation with abnormal liquefaction.
abstract: Five different enzyme activities were estimated in ejaculates obtained from 96 men visiting our infertility clinic. Sperm count showed a significant positive correlation with aspartate-aminotransferase (GOT) and alanine-aminotransferase (GPT). Acid phosphatase was positively correlated with gamma-glutamyl transpeptidase (GGTP) and citrate and negatively with fructose. GGTP showed similar relationships with citrate and fructose. For beta-glucuronidase a low positive correlation with GGTP and GOT was detected. The enzyme activities of 27 ejaculates with a high viscosity were not significantly different from the activities of ejaculates with normal liquefaction. The conclusion is reached that insufficient prostatic enzyme secretion is not the cause of abnormal liquefaction in these patients.
