It’s a boy!
A few months ago, after a fertility procedure at a Mexican clinic, a healthy baby boy was born in New York to a couple from Jordan. It was the first live birth of a baby to be born using a new technique that incorporates DNA from three people.
The technique, meant to prevent Leigh syndrome, was used by Dr John Zhang, of the New Hope Fertility Clinic in New York. It involved taking the nucleus from one of the mother's eggs – containing her DNA – and implanting it into a donor egg that had its nucleus removed but retained the donor’s healthy mitochondrial DNA.
For parents with rare genetic mutations to have healthy babies, this controversial technique has only been legally approved in the UK. But the birth of this child should fast-forward progress around the world, say embryologists.
Although this has resulted in a healthy baby boy, many scientists are still concerned.

For his part, Zhang has a history of working on the cutting edge of reproductive medicine. Over a decade ago, he implanted embryos with genetic material from three parents into a woman in China, and triplets began to grow. All three died before birth, but doctors at the time felt they might’ve made it if the woman had access to the better medical care available in the U.S.
