In an attempt to avoid congenital abnormalities that have killed two children before, some doctors eventually combine the cell nucleus of DNA (nuclear DNA) with mitochondria (maternal DNA) from an egg donor, which is then fertilized with his father's sperm,
This is the first attempt in the world to use a controversial three-parent technique, first reported in New Scientist magazine.
These Jordanian parents signed up to get help from doctors in the US and were flown to Mexico to undergo this procedure because the fertilization techniques of these 3 parents were not approved in the US.
Some experts criticized the announcement of this experiment conducted through a report in the magazine rather than revealed in a journal reviewed by scientists, saying more research needs to be done to understand the research.
