Louise Brown, 40.

6:00am, July 25, 2018
Born on July 25, 1978, Louise Brown, shown here at the Science Museum in London next to her baby picture, was the first baby conceived with IVF. Today, the procedure has led to the birth of millions of babies.

At 11:47 p.m. on July 25, 1978, a baby girl was born by cesarean section at the Royal Oldham Hospital in England. This part of her arrival was much like many other babies’ births: 10 fingers and 10 toes, 5 pounds, 12 ounces of screaming, perfect newborn. Her parents named her Louise. But this isn’t the most interesting part about Louise’s origins. For that, you have to go back to November 12, 1977, also near midnight. That’s when Louise Joy Brown was conceived in a petri dish.

50 years ago, scientists took baby steps toward selecting sex

in vitro fertilization

UNDER THE MICROSCOPE  The modern science of in vitro fertilization began 50 years ago, with an experiment in rabbits that selected for their sex.

Toward preselected sex
Robert Edwards and Richard Gardner of Cambridge University … say they have been able to remove rabbit embryos … then reimplant only the blastocysts destined to develop into the chosen sex. The implications are obvious and enormous. If this procedure could be extended easily to man there might, for instance, be imbalances, even fads, in the selection by parents of one sex of child over another. — Science News, August 3, 1968.


Edwards helped pioneer in vitro fertilization, resulting in the first IVF baby in 1978 and a Nobel Prize in physiology or medicine in 2010. He also foresaw technology’s potential for sex selection. With no sex selection, about 105 males are born for every 100 females worldwide. But in places where sex selection has been encouraged, through IVF and other methods, changes have resulted. In 1995, China’s ratio was 115 boys per 100 girls, according to U.N. estimates. By 2015, men outnumbered women in China by more than 42 million. In 2017, China ended its one-child policy
