Professor Sailesh Kotecha is a Neonatologist at Cardiff University and believes more research is needed into stillbirths.
He told ITV Wales: "The rate of stillbirths in Wales is somewhere between 4.5 - 5 per thousand births. That means some 170 babies are dying unnecessarily in many cases.
"We can do better. If you look at the rates of stillbirth in Sweden and other Scandinavian countries, it's half of what we have here in Wales and the rest of the UK."
