'As the mother of one of the world's first IVF babies, the depth of information in this brilliant, engaging book is thrilling to me. Edwards and Steptoe resiliently persevered, using their intellects and scientific experimentation, to create and hone the pioneering process that resulted in the creation of families world-wide. I live in eternal gratitude to these two men and revere the authors who today bring this 1979 lecture to light.'
