A team of doctors from Greece and Spain have reported the birth of a baby using DNA from three people. The baby boy has inherited the genetic material from two women and a man.

Doctors used an egg from the infertile mother, the father’s sperm and another woman’s egg to conceive the baby boy. The doctors transferred genetic material with chromosomes from the mother to the egg of a donor whose own genetic material had been removed in a process.

In-vitro Fertilization is an artificial reproduction technique wherein the process of fertilization happens by extracting eggs, retrieving a sperm sample, and then manually combining an egg and sperm in a laboratory set-up. The embryo(s) is then transferred to the uterus.
