World's First Test-Tube Baby Louise Brown Born
Infertility treatments advanced in Britain through the work of obstetrician Patrick Steptoe, physiologist Robert Edwards, and embryologist Jean Purdy at Oldham General Hospital. After years of laboratory research on in vitro fertilization, an egg from Lesley Brown was fertilized with sperm from her husband John in a Petri dish. The resulting embryo was implanted, leading to a successful pregnancy. On July 25, Louise Joy Brown was delivered by cesarean section just before midnight, becoming the first human born via IVF. The birth drew global media attention and ethical debate but proved the technique viable.
