SPERM ANGIOTENSIN-CONVERTING ENZYME-ACTIVITY IN CHERNOBYL VICTIMS ANDPATIENTS WITH CHRONIC PROSTATITIS

The method for determination of angiotensin-converting enzyme activity in human spermatozoa and seminal plasma was developed. The number of total and active-motile spermatozoa was shown to be lower in Chernobyl victims than in healthy donors. The specific activity of angiotensin- converting enzyme in spermatozoa from Chernobyl victims was 12 times h igher than that in donors. Similar results, although to a lesser exten t, were observed in patients with chronic prostatitis. In contrast, th e enzyme activity in blood serum and seminal plasma was identical for all subjects investigated.
