IVF Changes Babies’ Genes But These Differences Disappear by Adulthood

September 3, 2019

(The Conversation) – Around one in 25 Australian children are now conceived through use of assisted reproductive treatments such as IVF. These reproductive technologies appear to leave a biological “signature” on several genes that can be measured at birth. This may explain why assisted conception increases the chance of early delivery, low birth weight and congenital abnormalities – and the question has remained about why this might be so. But the good news, according to our research published today in the journal Nature Communications, is these “epigenetic” changes largely disappear by adulthood. In fact, people born via IVF are as healthy as their naturally conceived peers.
