What event initiated the specialized branch of medicine called assisted reproductive technology?

The event that initiated the specialized branch of medicine called assisted reproductive technology was the birth of Louise Brown in 1978. Louise Brown was the first "test tube baby," conceived through in vitro fertilization (IVF). This groundbreaking event marked the beginning of a new era in reproductive medicine, allowing couples who were unable to conceive naturally to have children. Since then, assisted reproductive technology has advanced significantly, with a variety of techniques and procedures developed to help individuals and couples overcome infertility.
