Aim: To assess the association of dietary antioxidants intake with semen quality parameters in infertile men. Methods: In this cross-sectional study, dietary antioxidant intake was evaluated in 175 Iranian infertile men by a validated dish-based 106-item semi-quantitative food frequency questionnaire. Linear and quantile regression was used to determine the association of antioxidant nutrients intake with semen quality parameters. Results: Mean age of study participants was 32.19 ± 2.34 years. Compared with the lowest quartile men in the highest quartile of dietary vitamin C and β-carotene intake had an inverse association with sperm DNA Fragmentation Index (DFI). Also, dietary intake of beta-cryptoxanthin and lutein had a positive association with sperm density and sperm total count respectively. Conclusion: These data suggest that dietary intake of some of the antioxidants is associated with semen related parameters.
