Today, Midday on Ethics. The growing popularity of services like 23andme and other personal genetic testing companies means it’s easier than ever to find long lost relatives – including some who were assured that they would never be found. For years, men and women who donated sperm or eggs were guaranteed anonymity. That’s a guarantee that’s no longer possible in an era when the children they helped create are easily tracking down their donor parents and, in some cases, a slew of siblings they never knew existed. Dr. Jeffrey Kahn is the Director of the Johns Hopkins Berman Institute of Bioethics. He joins me to discuss promises of privacy that can no longer be kept.
