Thirty-six years ago, Louise Brown became the first baby born from a new experimental reproductive procedure called in vitro fertilization (IVF). Her British parents had been trying to conceive for nine years, but they struggled with infertility due to the mother’s blocked fallopian tubes.IVF seemed like science fiction to many observers at the time.

IVF launched a revolution in the field of reproductive medicine that continues today, with new advancements helping women conceive.
