Robert Geoffrey Edwards, a British developmental biologist at University of Cambridge, began exploring human in vitro fertilization (IVF) as a way to treat infertility in 1960. After successfully overcoming the problem of making mammalian oocytes mature in vitro in 1965, Edwards began to experiment with fertilizing matured eggs in vitro. Collaborating with other researchers, Edwards eventually fertilized a human egg in vitro in 1969. This was a huge step towards establishing human IVF as a viable fertility treatment. During the four years in which Edwards experimented with IVF, he experienced many setbacks. These failures in fertilizing oocytes in vitro, however, contributed to the understanding of how fertilization did or did not happen, which was sometimes different from established dogmas. Edwards also collaborated with gynecologist and surgeon Patrick Christopher Steptoe to study sperm capacitation, which became the overture that heralded a series of successes for the team, culminating in the generation of the first test-tube baby Louise Joy Brown in 1978.

The biomedical accomplishment of human in vitro fertilization and embryo transfer (IVF-ET) took years to become the successful technique that presently enables infertile couples to have their own children. In 1969, more than ten years after the first attempts to treat infertilities with IVF technologies, the British developmental biologist Robert Geoffrey Edwards fertilized human oocytes in a Petri dish for the first time. In 1970, Edwards and his research partner, gynecologist and surgeon Patrick Christopher Steptoe, started working with human patients with complicated and individualized gynecological conditions. It took Edwards and Steptoe another eight years of modifying medical procedures, as well as dealing with the ups and downs of funding situations and public opinions, before they could celebrate birth of the first baby conceived through IVF-ET in 1978.

Zhang Lizhu is a Chinese gynecologist and researcher. For most of her career, she worked in the Peking Medical College Third Hospital, renamed in 2000, Peking University Third Hospital. There, she led a team of researchers and physicians in the study of human in vitro fertilization (IVF) and embryo transfer (ET) technology. Zhang and her colleagues contributed to the birth of the first test-tube baby in Mainland China in 1988.
