In recent months the British media has been full of coverage about babies made using DNA from three people. The BBC’s coverage, which was entirely typical, quoted the mother of one baby boy speaking of “hope, joy and deep gratitude”, with glowing encomiums from other commentators on the technique, which the BBC described as follows:
“The eggs from both the mother and the donor are fertilised in the lab with the dad’s sperm. The embryos develop until the DNA from the sperm and egg form a pair of structures called the pro-nuclei... The pro-nuclei are removed from both embryos and the parents’ DNA is put inside the embryo packed with healthy mitochondria.”
