Human Fertility, September 2009; 12(3): 137–143 THIRTY YEARS OF IVF Thirty years of IVF: The legacy of Patrick Steptoe and Robert Edwards PETER R. BRINSDEN Consultant Medical Director, Bourn Hall Clinic, Cambridge, UK Abstract In this article, the author presents a review of the early collaboration between Patrick Steptoe and Robert Edwards, gynecologist and scientist, which ultimately led to the birth of Louise Brown in 1978, the first baby to be born as a result of in-vitro fertilisation. Following this momentous event, the author shows how Steptoe and Edwards continued to influence further developments in the treatment of infertile couples, both in the United Kingdom and Worldwide.
