Last week a story broke about the world’s first baby born via a new technique called mitochondrial donation. Mitochondrial donation is the newest version of in vitro fertilization (IVF), and creates babies who genetically have three parents.
This new technique involves taking an egg cell from the biological mother, extracting the nucleus of the egg, and placing the nucleus into a donor egg cell which also has the nucleus extracted. The new egg cell (which contains the nucleus of the biological mother’s egg and the rest of the cell from the donor mother) is fertilized with the father’s sperm, creating an embryo. The embryo is then implanted into the mother.
