|Abstract:||The epigenetic mechanism plays an important role in spermatogenesis such as DNA methylation where this episode is represented by either switching genes on or off. Twenty-eight samples (14 case and 14 controls) were subjected to Infinium 450K BeadChip arrays to identify genomic regions that differ in sperm DNA methylation patterns in the subfertile compared to the proven fertile group. Then two CpGs were validated by deep bisulphite sequencing on 82 sperm samples. The results screening study revealed eight CpGs were significantly different in their sperm DNA methylation levels between cases and control group. The results of the validation study for the two CpGs (cg19779893 and cg19406113) showed that a significant variation in the methylation level at 2 CpGs of 3 CpGs related to cg19779893 site amplicon in cases compared to the controls. Moreover, six CpGs related to the cg19406113 site amplicon showed significant differences in sperm DNA methylation between the cases and the control group. Furthermore, there was a significant decrease in the sperm parameters in the cases compared to the control group. This study found two CpGs altered in their sperm DNA methylation levels. In addition, a strong association was found between changes in the sperm DNA methylation levels in these CpGs sites and sperm parameters.|
