Have you ever heard of in-vitro fertilization (IVF)? While it was considered experimental in the 1970s, British parents Lesley and Peter Brown knew that IVF was their best option to have a child. Thankfully, Lesley successfully gave birth to her baby girl via IVF in 1978. Find out what happened on the day that the first test tube baby was born.

A tiny miracle

On July 25, 1978, the Browns gave birth to Louise Joy Brown in Manchester, England. Little Louise had just made history for being the world’s first IVF birth. Overwhelmed with joy, Lesley delivered her bundle of joy in the middle of the night through a C-section, weighing just over five pounds. You might be wondering: why did the Browns use IVF in the first place?

The ultimate test

While Lesley Brown always wanted to start a family, she had never been able to conceive on her own. Toward the end of 1977, Lesley decided to start the IVF process in order to get pregnant. The procedure was simple: doctor-scientist duo Patrick Steptoe and Robert Edwards combined Lesley and her husband’s DNA to create an embryo. Then, the embryo was surgically inserted into her reproductive system.

The next generation

Once the public learned that Lesley was pregnant, the media had a field day after her IVF operation. When Louise was finally born, it made international headlines. Soon afterward, the Browns had another baby, Natalie, through an IVF procedure as well. Want to know the craziest part? In 1999, Natalie also broke records when she had her own baby because she was the first test tube baby to give birth. Seven years later, Louise had a baby boy as well. Even though it was criticized at first, IVF has become a great option for families who need help getting pregnant.
