Did you know that the first-ever test tube baby is now 46 years old? Louise Brown was born in London on July 25, 1978, via in vitro fertilization. As a baby, she was brought out on TV to show the success of IVF, a process pioneered by gynecologist Patrick Steptoe and developmental biologist Robert Edwards. What’s remarkable about their story is that they tried and failed 101 times to fertilize an egg with sperm in a petri dish outside the body before they were able to succeed. Thanks to their tenacity and determination, IVF is now a procedure that’s available to people around the world who want to have a genetically related child!
