ABSTRACT

Objective: to determine if eating habits, physical activity and BMI can influence assisted reproduction outcomes. Material and Methods: this study analyzed 436 patients undergoing intracytoplasmic sperm injection cycles. Patients answered a questionnaire and regression analysis examined the relationship between lifestyle and BMI with the intracytoplasmic sperm injection cycles outcomes. Results: no influence of lifestyle and obesity was observed on the number of oocytes recovered. Obesity reduced the normal fertilization rate (coefficient [Coef.]: −16.0; p = 0.01) and increased the risk of miscarriage (OR: 14.3; p = 0.03). Physical activity positively affected implantation (Coef.: 9.4; p = 0.009), increased the chance of pregnancy (OR: 1.83; p = 0.013) and tended to decrease the risk of miscarriage (OR: 0.30; p = 0.068). In addition, an inverse correlation was found between physical activity and BMI, and a direct correlation was found between soft-drink consumption and BMI. Conclusions: eating habits, physical activity and obesity could affect clinical outcomes of assisted reproduction.
