LDH isoenzymes (LDH1, LDH2, LDH3, LDH4, LDH5, and LDHx) were evaluated in 68 infertile men and in a control of 10 fertile men. No statistically significant difference was found in the value of the 5 isoenzymes (LDH 1-5) in the different subgroups of infertile men and in the comparison of the infertile men with the control group. LDHx was detected in the infertile men, regardless of the cause of infertility, as long as the sperm concentration was greater than or equal to 16 million/ml, LDHx was not detected not only in all azoospermic men but, also, in those infertile men whose sperm count was less than or equal to 15 million/ml. There is a positive relationship (p less than 0.001) between LDHx and sperm concentration, but there is no such relationship between LDHx and % motility.
对68名不育男性和10名生育能力正常男性的对照组进行了乳酸脱氢酶同工酶（LDH1、LDH2、LDH3、LDH4、LDH5和LDHx）评估。在不育男性的不同亚组中，以及不育男性与对照组的比较中，5种同工酶（LDH 1 - 5）的值未发现有统计学显著差异。在不育男性中检测到了LDHx，无论不育原因如何，只要精子浓度大于或等于1600万/毫升即可检测到；不仅在所有无精子症男性中未检测到LDHx，而且在精子计数小于或等于1500万/毫升的不育男性中也未检测到。LDHx与精子浓度之间存在正相关关系（p小于0.001），但LDHx与活力百分比之间不存在这种关系。
