Effect of energy expenditure and physical activity on the outcomes of assisted reproduction treatment.

It is still not definitely resolved whether being physically active has any impact on the success of assisted reproduction treatment. To this end, this study used the International Physical Activity Questionnaire short form (IPAQ-sf). Data from the IPAQ-sf were classified into three categories: low, moderate and high physical activity as defined by the IPAQ working group. The subjects in the study were grouped according to their physical activity levels during treatment. None of the subjects met the criteria for high physical activity. The low activity group consisted of 68 women whereas moderate activity group consisted of 63 women. The study showed that women undergoing assisted reproduction treatment significantly decreased their activity level during the treatment period (P<0.05). However, women who were physically more active were more likely to have an increased implantation rate and a live birth.
