title: Physical activity, obesity and eating habits can influence assisted reproduction outcomes.
abstract: OBJECTIVE
  To determine if eating habits, physical activity and BMI can influence assisted reproduction outcomes.
  
  
  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.
