After thousands of dollars of in vitro fertilization treatments and nine months of pregnancy, a New York couple was forced to give up the twins they birthed. It turns out CHA Fertility Center, the Los Angeles clinic where the couple sought IVF treatment, mixed up the embryos of three patients, resulting in two of the couples having to give up children to their genetic parents. Now, those parents are suing.

Dov Fox, professor of law at the University of San Diego and the director of the school’s Center for Health Law Policy & Bioethics, said the law has not caught up with reproductive technology and victims of this type of medical malpractice aren’t left with many legal options. Yet, legal frameworks are out there, Fox said. Judges and lawmakers just might need to look outside the U.S.
