Last week, scientists announced the birth of eight healthy babies in the United Kingdom conceived with DNA from three people. Some headlines have called it “three-person IVF”.
The embryo uses the DNA from the egg and sperm of the intended father and mother, as well as cells from the egg of a second woman (the donor).
This process – known as mitochondrial replacement therapy – allows women with certain genetic disorders to conceive a child without passing on their condition.
