The man whose research led to the world's first test-tube baby more than three decades ago, has died at age 87.
Robert Edwards, who later won the Nobel Prize, began experimenting with in vitro fertilization, or IVF, in the late 1960s. His work, controversial at the time, eventually led to the birth of the world's first "test tube baby," Louise Brown, on July 25, 1978.
Since then, IVF has resulted in about 5 million babies worldwide, according to the European Society for Human Reproduction and Embryology.
