Le résumé fourni par la source

Abstract Objective Infertility had an increasing trend between couples in Iran. Several factors such as lifestyle, physical activity, unhealthy dietary habits and stress are associated with production of ROS in seminal fluid. The aim of this study was to identify the role of dietary antioxidants and vitamins intake on semen quality parameters, among Iranian infertile men. Methods This cross-sectional study was performed on 400 newly diagnosed infertile men in Yazd Reproductive sciences Institute from July 2019 to December 2019. The presence of infertility was confirmed by an expert andrologist, based on WHO criteria. Dietary antioxidants and vitamins intake were assessed using a 168 items semi-quantitative food frequency questionnaire (FFQ). Results We found an association between semen volume and Alpha Carotene dietary intake, total motility and Beta Cryptoxanthin dietary intake, and sperm count with riboflavin intake (P = 0.03). Conclusions We concluded that dietary intake of Alpha Carotene, Beta Cryptoxanthin, and Riboflavin are related to sperm count, semen volume and total motility in Iranian infertile men, respectively. Our data suggest that that adhering to a diet that is rich in sources of antioxidant and vitamin can have a positive effect on men’s sexual health. However, more research is needed to confirm these relations and provide the evidence needed to exert these findings into clinical practice.
