Materials and Methods This prospective study conducted on 219 infertile women. We evaluated patients’ BMI, total calorie intake and PA in their assisted reproduction treatment cycles. Malondialdehyde (MDA) and total antioxidant capacity (TAC) in pooled FF at oocyte retrieval were additionally assessed. Results There was no relation between OS biomarkers to total calorie intake and PA. The TAC levels in FF adjusted for age, duration of infertility, etiology of infertility, number of used gonadotrophin and PA showed a positive relation to BMI (p=0.001). The number of used gonadotrophin and PA had a negative relation to duration of infertility (p=0.03) and anovulation disorder as an etiology of infertility. The MDA level in FF had a positive association with anovulation disorder as the etiology of infertility (p=0.02). MDA in FF was unaffected by BMI. Conclusion Increasing age, BMI and PA do not affect OS in FF. In women with longtime infertility and those with anovulation disorder as an etiology of infertility, decreased potent antioxidant defense in the follicular microenvironment may contribute to ovarian function. Therefore antioxidant supplements may be beneficial for these groups of women.}, keywords = {Energy Expenditure,Calorie intake,Physical activity,Oxidative stress,follicular fluid}, url = {https://www.ijfs.ir/article_45239.html}, eprint = {https://www.ijfs.ir/article_45239_3c098bb3ae3d14848bfb6740ccc8d5bc.pdf} }
