Ricardo Hector Asch (born 26 October 1947)[1] is an obstetrician, gynecologist, and endocrinologist. He worked with reproductive technology and pioneered gamete intrafallopian transfer (GIFT), as well as working on research linking fertility and marijuana usage,[2] and investigated the use of GnRH analogues with Andrew Schally.[3][4] In the mid-1990s he was accused of transferring ova harvested from women into other patients without proper consent at the University of California, Irvine's fertility clinic. Asch left the United States one year before a federal indictment was filed.[5][6] He was tried and acquitted of all charges in Argentina in 2008.[7] In 2011 Mexico denied an extradition request by the United States as it would constitute double jeopardy and no new evidence was brought forth.[8] He is currently living in Mexico City.[9][10]
