We all know how babies are made: sperm meets egg, molecular magic happens, and an entire human comes to life from a single cell.
But is that the only way?
For a decade, scientists have been in a heated race to redefine reproduction as we know it. Relying on a Nobel Prize-winning technique, these cellular reprogrammers are painstakingly uncovering the secret code that can turn a skin or blood cell into other cell types—including those that link one generation with the next.
If they succeed, the implications are mind-blowing: with a simple blood draw or cheek swab, scientists could erase those cells’ identities and transform them into bona fide sperm or egg cells. Infertility could be a thing of the past. Women could have children regardless of age. Scientists even believe we may one day make a man’s skin cells into eggs and a woman’s into sperm—this “sexual reversal” could allow same-sex couples to reproduce.
