Children born of this technology will have three genetic parents, insofar as they will have genetic material from a male sperm provider and two female egg providers.
This report, authored by the Committee on the Ethical and Social Policy Considerations of Novel Techniques for Prevention of Maternal Transmission of Mitochondrial DNA Diseases, makes a number of important contributions to the ethics and policy debates.
The Committee’s approach to mitochondrial replacement technology is notably more cautious than that adopted in the United Kingdom. The Committee recommends limiting research to the intrauterine transfer of genetically modified male...
