“For some patients, it’s very hard to accept that they cannot get pregnant with their own [eggs],” he said.

“Spindle transfer may represent a new era in the IVF field, as it could give these patients chances of having a child genetically related to them.”

A woman's inalienable right

The president of the Institute of Life, Dr Panagiotis Psathas, also defended the treatment, telling The Independent: “Today, for the first time in the world, a woman’s 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," Psathas added.

Three person IVFs have been used before in Jordan, Mexico and Ukraine and have all been met with controversy.
