Controversial ‘3-Parent Baby’ technique — originally intended to avoid mitochondrial disease, but used more frequently for fertility treatment — presumed to work in women under age 37, but not older women
Doctors at a Ukrainian clinic tried '3-person IVF' in older women to boost fertility. Verdict: it didn't work. My story: #ASRM2019
Accurate update on "three-parent babies", aka moving genetic material from one woman's egg into that of a young healthy egg donor. Doesn't work for age-related fertility which is major reason for IVF. (But further attempts will be made).
