The Nobel Prize for Mediciine for 2010 has been awarded to the scientist who invented invitro fertilization (IVF).

Dr Robert Edwards, the 85-year-old professor emeritus at the University of Cambridge, started working on IVF as early as the 1950s. He developed the technique, in which egg cells are fertilized outside the body and then implanted in the womb, together with gynocologist surgeon Patrick Steptoe, who died in 1988. The first baby was Louise Brown who was born on July 25, 1978. About four million people have been born with the aid of this technique. Read more of this story
