The Committee on  Assessing the Medical Risks of Human Oocyte Donation for Stem Cell Research conducted a public workshop on September 28, 2006 at the Hyatt Regency San Francisco Airport. The purpose of the workshop was to discuss and explore the most recent data on the potential risks associated with oocyte donation. The goal was to assess and explore the nature and magnitude of risks, evaluating areas where more data are required, and assessing what is known about the potential for reducing risks through changes in procedures.
