British IVF pioneer Robert Edwards wins Nobel prize
The 2010 Nobel Prize in medicine has been awarded to a British professor who pioneered in vitro fertilisation treatment now commonly known as IVF.
Eighty five year old Dr Robert Edwards helped to develop the technique in which cells are fertilised outside the body and implanted in the womb.
The breakthrough has helped millions of infertile couples have children.
