New study on genetic risks of IVF

by Sarah Pritchard

A large study has investigated the potential genetic risks to children conceived by in vitro fertilisation (IVF). It confirms earlier research indicating that babies born following assisted conception have a small increased risk of certain genetic health problems. The New York Times reports that in November last...
