| Abstract:
Background: To examine the relative contributions of dietary fat intake level and its food sources and assisted reproduction parameters.
Materials and Methods: A prospective study was conducted on 240 infertile women. In assisted reproduction treatment cycle, body mass index (BMI), physical activity (PA), calorie intake, fat consumption and major food sources were assessed. The number of retrieved oocytes, fertilization rate and embryo quality were also determined.
Results: Total fat intake adjusted for age, BMI, PA and etiology of infertility was positively associated with the number of retrieved oocytes and inversely associated with the high embryo quality rate. An inverse association was observed between sausage and ham intake and the number of retrieved oocytes. Vegetable oil intake level and good cleavage rate had an inverse association. Nuts intake was positively related to the number of retrieved oocytes and number of high embryo quality.
Conclusion: The results revealed that higher fat consumption level tends to raise the number of retrieved oocytes, and adversely relates to embryonic development.
Of the food sources of fat, high intake of vegetable oil, sausage and ham may adversely affect assisted reproduction parameters. Also, nuts intake may have positive effect on assisted reproduction treatment.
