Unapproved technique gives baby 3-parent DNA, to save his life

To make sure the baby was born healthy, a new technique was used that gave the world the first baby born with DNA from 3 different people.

A New York fertility specialist, who said he successfully carried out a "three-parent" in vitro fertilisation (IVF) technique resulting in a baby boy, called the procedure a "revolutionary approach in human reproduction."

John Zhang, medical director of New Hope Fertility Center in New York, spearheaded the technique roughly five months ago with a Jordanian couple at a clinic in Mexico.
