The world's first baby using a new "three person" fertility technique has been born in Mexico, reported New Scientist magazine.

According to New Scientist, the baby is now five months told. His parents are Jordanians and the work was carried out by a team of experts from the US.

The five-month-old boy has the usual DNA from his mother and father, plus a tiny bit of genetic code from a donor.

The child's mother has Leigh syndrome, a fatal disorder that affects the developing nervous system and would have been passed on in her mitochondrial DNA.

While she is healthy, Leigh syndrome was responsible for the deaths of her first two children.

The couple then approached a team of doctors at the New Hope Fertility Center in New York City. 

The team used a method that takes all the vital DNA from the mother's egg plus healthy mitochondria from a donor egg to create a healthy new egg that can be fertilised with the father's sperm.

Their technique uses a healthy donor egg to provide healthy mitochondria.

The technique has not been approved in the US, so the team travelled to Mexico because there are no laws there that prohibit it.
