Women who are more physically active in the year before in vitro fertilization increase their chances to have a successful pregnancy, according to a study led by Dr. Kelly R. Evenson, research professor of epidemiology at the University of North Carolina Gillings School of Global Public Health. Dr. Evenson and a team of co-researchers presented the findings in a paper published online in Fertility and Sterility, the journal of the American Society of Reproductive Medicine. Results derived from 121 women showed that lifestyles that included more active living – walking, bicycling, active transportation, and less TV-watching – as well as sports and exercise, appeared to favor implantation and pregnancy.
