Among these nine highly prevalent polymorphism areas (Table II), the allele frequencies of three SNPs in asthenozoospermia men including 373C>A (r s2070923) and 298G>C (rs1646022) in PRM2 and 139C>A (rs737008) in PRM1 were insignificantly higher than the control group (Figure 2). This evidence concerns the gene PRM1 and Reduced sperm motility.
