Birth and early life
Louise Joy Brown was born at Oldham General Hospital, Oldham, by planned Caesarean section delivered by registrar John Webster. She weighed 5 pounds, 12 ounces (2.608 kg) at birth. Her parents, Lesley and John Brown, had been trying to conceive for nine years. Lesley faced complications of blocked fallopian tubes.
On 10 November 1977, Lesley Brown underwent a procedure, later to become known as in vitro fertilisation (IVF), developed by Patrick Steptoe, Robert Edwards and Jean Purdy. Purdy was the first to see her embryonic cells dividing. Edwards, as the only surviving partner, was awarded the 2010 Nobel Prize in Medicine for this work. Although the media referred to Brown as a "test tube baby", her conception actually took place in a Petri dish. Her younger sister, Natalie Brown, was also conceived through IVF four years later, and became the world's fortieth child after conception by IVF. In May 1999, Natalie was the first human born after conception by IVF to give birth herself—without IVF.
