Fertility doctors say they have produced the worlds first three-person baby after an infant was born with DNA from two women.
Scientists in Greece and Spain say the accomplishment made medical history and could help infertile couples around the world.
The baby boy was born on Tuesday weighing 6lbs and both the mother, 32, and baby are said to be in good health.
British fertility experts have raised concerns about the ethics of the procedure, an experimental form of IVF which uses an egg from the mother, sperm from the father, and another egg from a donor woman.
The mother was a Greek woman with a history of multiple IVF failures.
The Maternal Spindle Transfer method was developed to help families affected by deadly mitochondrial diseases which are passed down from mother to baby.
Fertility doctors believe the technology could increase the odds of IVF.
President of the Institute of Life in Athens, Dr Panagiotis Psathas, said: Today, for the first time in the world, a womans inalienable right to become a mother with her own genetic material became a reality.
As Greek scientists, we are very proud to announce an international innovation in assisted reproduction, and we are now in a position to make it possible for women with multiple IVF failures or rare mitochondrial genetic diseases to have a healthy child.
At the Institute of Life, our commitment is to continue to help even more couples facing fertility issues to have children with their own DNA, without having recourse to egg donors.
The Greek team were working with the Spanish centre Embryotools, which has announced that 24 other women are taking part in the trial and eight embryos are ready to be implanted.
Embryotools co-founder Dr Nuno Costa-Borges added: The completely successful and safe implementation of the Maternal Spindle Transfer method – for the first time in medical history – is a revolution in assisted reproduction.
I want to thank and congratulate the whole european team that made it possible, and especially the Institute of Life IVF Center.
He said it will help countless women to realise their dream of becoming mothers with their own genetic material.
