We could see a three-person baby in Britain soon as the law already allows this.
A baby has been born to a previously infertile couple in Ukraine using a new type of "three-person IVF". 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 girl, 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. The Kiev team fertilised the mother's egg with her partner's sperm. They then transferred the combined genes into an egg taken from a donor. The child has the genetic identity of the parents, alongside a tiny amount of DNA from the second woman.
