The fertility doctor responsible for the Octomom’s brood has been expelled from the American Society of Reproductive Medicine, the biggest U.S. organization for fertility doctors. Dr. Michael Kamrava reportedly broke with the organization’s guidelines by implanting six embryos in “Octomom” Nadya Suleman, two of which split into twins. The group recommends transferring only one or two embryos to women younger than 35 specifically to avoid Octomom-esque results. Dr. Kamrava typically implanted around four embryos in his patients. Though the ASRM does not have the power to actually revoke a medical license, a spokesman for the organization said, "I think it's our responsibility to set standards of care."
