Three-person IVF

Three-person IVF baby for infertile couple

The Times reports that doctors in Kiev used a method called pronuclear transfer in what is a world first.

It is not the first baby born with DNA from three parents, however.

The baby, born on 5 January, is thought to be the world's second "modern three-parent baby" - another child was created using a slightly different method in Mexico last year.

'It is time to make' three-person babies

The move has been described as "historic", and the regulator will make its decision next month.

Doctors want to make babies from three people to prevent diseases that starve the body of energy, leading to brain damage, muscle wasting and heart failure.

However, fresh evidence suggests it will fail in one in eight pregnancies.

Three-person IVF replaces the defective power packs in the mother's egg - called mitochondria - with healthy ones from a donor woman.
