Background: Infertility is a disease of the reproductive system defined by the failure to achieve a clinical pregnancy after 12 months of regular unprotected sexual intercourse. Male infertility affecting 15% of couples. Environmental and genetic factors are involved in male infertility. Paraoxonase (PON) is an antioxidant enzyme which plays an important role in various diseases and is associated with oxidative stress and lipid metabolism. The PON gene family consists of 3 genes, PON1, PON2, and PON3, that located on the long arm of chromosome 7. In this study, the association of PON1 gene polymorphism at position 192 Q/R with idiopathic male infertility were investigated.

Materials and Methods: Blood Samples were collected from 120 patients diagnosed with idiopathic male infertility and 124 control subjects, and genotyped by PCR-RFLP method. To estimate the association between genotype and allele frequencies in cases and controls, P-values were assessed by Chi-square (&chi2) analysis.

Results: We observed a significant difference in genotype distributions of PON1 192 Q/R polymorphism between patients and controls (P= 0.0001). Our findings revealed individuals with the variant QR and RR had a significant decrease risk of idiopathic male infertility (RR: OR= 0.057, 95%CI=0.003-1.08, P= 0.05. QR: OR= 0.288, 95%CI= 0.132-0.394, P= 0.0001).

Conclusion: Our data indicate that the PON1 192 Q/R polymorphism maybe associated with decreased risk of idiopathic male infertility. Although more studies should be considered with larger number of patient and control subjects to confirm our results.
