Washington: Men who are thinking about having kids are advised to shed those extra kilos before conceiving to assist with fetal development.Reproductive experts from the University of Melbourne’s Department of Zoology have discovered that a father’s obesity negatively impacts sperm, resulting in smaller fetuses, poor pregnancy success and reduced placental development. While the health risks surrounding obesity and pregnancy have largely been centred on overweight mothers, scientists from the University of Melbourne are putting the onus on men to shape up.“A lot of men don’t understand what contribution they’re having, but they need to be healthy before conceiving. Sperm needs to be match fit for the games of life and creating life is the biggest thing that we can do,” said Professor David Gardner, who conducted the study with Dr Natalie Hannan and PhD student Natalie Binder.The study used in vitro fertilisation (IVF) on animals to determine the effects of paternal obesity on embryo implantation into the womb and fetal development.
