Five months ago, on April 6th of this year, a boy born to a Jordanian couple became the first baby born in the world using a new in-vitro fertilization technique that uses the DNA material from two women and one man, according to a report out today in New Scientist.

A U.S. team of doctors assisted with the birth, which took place in Mexico, according to New Scientist, as the technique has not been approved in the United States. However, its overwhelming success could help the approval process in the United States to be green-lit by the FDA soon.

The couple decided to go through with the technique after they found out that the baby boy's mother is a carrier for Leigh syndrome, a fatal disease that afflicted her first two children; the first died at age six from the disease, and the second at just eight months. The disease-causing mutation is found in the mother's mitochondria, and the three-parent technique avoided using her mitochondria all together.
