Abstract
This study included 43 semen samples collected from sub-fertile and 10 samples of fertile men, after the abstinence period (3 to 5 days); it was conducted in the laboratory of Babylon Maternity and children, and private laboratories during the period from October 2016 to March 2017. The study was aimed to expose for reasons of unexplained infertility in most cases, through valued the correlation between LDH activity and sperm concentration in the seminal plasma of infertile men and in comparison it with fertile men. The results revealed significant differences (P˂0.05) in an average of the activity level of Lactate dehydrogenase enzyme between the different groups, the highest level was shown in the groups of fertile and normospermia and the lowest level in the oligospermia and oligo-asthenospermia, also revealed a significant negative correlation (P˂0.05) between LDH activity and sperm concentration in the seminal plasma of oligo-asthenospermia, the negative correlation observed in the group of normospermia and oligospermia while fertile men has positive correlation.
