Ricardo Asch

Ricardo Hector Asch (born 26 October 1947) is an Argentine-Mexican 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, and investigated the use of GnRH analogues with Andrew Schally. 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. He was tried and acquitted of all charges in Argentina in 2008. In 2011, Mexico denied an extradition request by the United States as it would constitute double jeopardy and no new evidence was brought forth. As of 2020, he is living in Mexico City.

Education and early career Born in Buenos Aires, Argentina, Asch studied at the University of Buenos Aires School of Medicine graduating in 1971. In 1975, he moved to the United States and worked with Robert Benjamin Greenblatt at the Medical College of Georgia before his reproductive endocrinology fellowship at the University of Texas Health Science Center at San Antonio. Among his many publications were his pioneering experience with GIFT and research on oocyte donation. In 1986, he joined the University of California, Irvine School of Medicine (UCI). In 1990, he became the Director of the Center for Reproductive Health of UCI heading the infertility program. Asch was named Assistant Dean of outreach at UCI, in charge of overseeing recruitment of minority students, the same year. He lectured worldwide and accrued two honorary professorships by 1994. These eggs were fertilized and the resulting embryos transferred to these other women, some of them then conceiving. At least 15 live births resulted from the alleged practice. Asch disagreed with the settlements because they did not allow him to prove his innocence or repair his reputation.

Asch was defended by students, and colleagues, including Robert Edwards, who accused the media of convicting him before he was charged.

The Orange County Registers investigations into these practices led to that paper's receiving the 1996 Pulitzer Prize for Investigative Reporting.

In 2006, university officials admitted to the Los Angeles Times that they had not notified at least 20 women whose eggs were allegedly used by Asch and his colleagues.

Aftermath Asch and colleagues Jose Balmaceda and Sergio Stone were indicted on charges of mail fraud and income tax evasion. Asch suspended his practice, sold his properties, and left for Mexico. Balmaceda escaped to Chile, while Stone stayed in the US and was convicted of insurance fraud in 1997 and paid a fine.

Asch later opened a practice in Mexico and later in Argentina. He was formally fired by the university in 2000. He attained a Mexican citizenship in 2001 in addition to his native Argentine citizenship.

Asch was arrested again in Mexico in November 2010. On December 30, 2010, the Mexican Attorney's General Office (PGR) announced on its website that it had initiated proceedings to have Asch extradited to the United States. However, Asch was released on bail in early 2011. Subsequently, the judge ruled that as Asch had already been tried in Argentina and acquitted, and as no new evidence was provided, the "double jeopardy" rule applied, thus Asch was free and would not be extradited to the United States.

Research Asch worked with reproductive technology and pioneered gamete intrafallopian transfer (GIFT),
