Lactate dehydrogenase (LD, EC 1.1.1.27) activity was determined in serum, seminal plasma and prostasomes from normozoospermic and azoospermic (due to vasectomy) men. A 10-fold higher activity was noted in seminal plasma as compared with serum. LD activity was enriched in prostasomes although a fairly large amount of enzyme activity seemed to be free in solution. Isoenzymes LD1, LD2 and LD3, present in prostasomes in about equal amounts, gave rise to a characteristic isoenzyme pattern that differed distinctly from that found in seminal plasma of normozoospermic men, the main isoenzyme of which was LD-X.
在正常精子数男性和无精子症（由于输精管切除术）男性的血清、精浆和前列腺小体中测定了乳酸脱氢酶（LD，EC 1.1.1.27）活性。与血清相比，精浆中的活性高10倍。虽然相当大量的酶活性似乎游离于溶液中，但LD活性在前列腺小体中富集。前列腺小体中存在的同工酶LD1、LD2和LD3含量大致相等，产生了一种特征性的同工酶模式，与正常精子数男性精浆中发现的模式明显不同，后者的主要同工酶是LD-X。
