‘3-person’ baby boy born in Greece

Athens: A 32-year-old woman in Greece has given birth to a baby produced from three people, creating medical history. The baby boy weighing 2.9 kg was born on Tuesday. The experimental form of IVF uses an egg from mother, sperm from father and another egg from a donor woman.

Dr Panagiotis Psathas, president of the Institute of Life in Athens, said: "A woman's inalienable right to become a mother with her own genetic material became a reality. 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."

The Greek team was working with Spanish centre Embryotools, which announced that 24 other women are taking part in trial and eight embryos are ready to be implanted.

The doctors say they are ‘making medical history.’ But some experts in the UK say the procedure raises ethical questions and should not have taken place. The experimental form was developed to help families affected by deadly mitochondrial diseases which are passed down from mother to baby.

It has been tried in only one such case - a family from Jordan - and that provoked much controversy.

But some fertility doctors believe the technology could increase the odds of IVF too. This is all about mitochondria - they are the tiny compartments inside nearly every cell of the body that convert food into useable energy. They are defective in mitochondrial diseases so combining the mother's DNA with a donor's mitochondria could prevent disease.

But there is also speculation mitochondria may have a role in a successful pregnancy too. The Greek woman who had endured four unsuccessful cycles of IVF is now a mother, but her son has a tiny amount of his genetic makeup from the donor woman as mitochondria have their own DNA.
