Second Edition
This second edition of Principles of Oocyte and Embryo Donation , published 15 years in the wake of the fi rst, is timely and welcome. The volume chronicles more recent stages of a scientifi c saga that began over 25 years ago whenin 1984 the fi rst oocyte and embryo donation births were reported [1, 2]. Though the fundamental science was sound, the fi rst births came only after researchers overcame technological limits of the time and excruciating public and private skepticism. Thus, the fi rst edition in 1997 chronicled the initial investigational and early clinical phases of oocyte and embryo donation.
