In this case-control study,some SNPs in PRM1 (c.49 C>T, c.102 G>T and c.230A>C) and PRM2 (rs545828790, rs115686767, rs201933708,rs2070923 and rs1646022) were investigated in 30 idiopathic infertile men with teratozoospermia (case group) incomparison with 35 fertile men (controls). This evidence concerns the gene PRM2 and Abnormal sperm morphology.
