British IVF pioneer Robert Edwards wins Nobel prize

British scientist Robert Edwards, the man who devised the fertility treatment IVF, has been awarded this year's Nobel prize for medicine.

His efforts in the 1950s, 60s and 70s led to the birth of the world's first "test tube baby" in July 1978.

Since then more than four million babies have been born following IVF.

The prize committee said his achievements had made it possible to treat infertility, a medical condition affecting 10% of all couples worldwide.
