Researchers at University of Melbourne in Australia say that not just women but men too should get themselves fit by losing the excess kilos before attempting to have a baby.
According to the study, to be presented at the Endocrine Society of Australia and the Society for Reproductive Biology 2012 annual meet, being overweight negatively impacts the sperm and also affects the growth of the fetus and placental development while also reducing the chances of success.
"We found that development was delayed in the fetuses produced from obese fathers. The rate of embryo implantation into the womb and fetal development decreased in these animals by up to 15 per cent. Furthermore, placental weight and development was significantly less for embryos derived from the sperm of obese males", lead researcher Natalie Binder said.
