Louise Brown, the first test-tube baby, is 38:
On this day in 1978, Louise Joy Brown, the world’s first baby to be conceived via in vitro fertilization (IVF) is born at Oldham and District General Hospital in Manchester, England, to parents Lesley and Peter Brown. The healthy baby was delivered shortly before midnight by caesarean section and weighed in at five pounds, 12 ounces.
Before giving birth to Louise, Lesley Brown had suffered years of infertility due to blocked fallopian tubes. In November 1977, she underwent the then-experimental IVF procedure. A mature egg was removed from one of her ovaries and combined in a laboratory dish with her husband’s sperm to form an embryo. The embryo then was implanted into her uterus a few days later. Her IVF doctors, British gynecologist Patrick Steptoe and scientist Robert Edwards, had begun their pioneering collaboration a decade earlier. Once the media learned of the pregnancy, the Browns faced intense public scrutiny. Louise’s birth made headlines around the world and raised various legal and ethical questions.
So far, more than five million babies have been born through IVF.
