摘要
A study on the activity of lactate dehydrogenase isoenzyme C4(LDH-C4) in spermatozoa and seminal plasma was performed in the following subjects: normal males were recruited as control, infertile men with or without normal semen quality were recruited as groups Inf. I and Inf. H, oligospermic patients were recruited as the 4th group. The ratios of LDH-C4 in seminal plasma to that in spermatozoa were 0.528(Pso) in the control, 0.88, 2.85 and 4.01 in Inf, I, H and oligospermic groups respectivel.v. All differences between the normal and the other groups were significant(P <0.005). The activity of LDH-C4 in spermatozoa might become an important biochemical index for estimation of semen quality and male fertility. A good correlation between LDH-C4 in spermatozoa was found (r = 0.9593).
