It was the most radical human-breeding experiment in American history—and no one knew how it ended. The Repository for Germinal Choice, dubbed the “Nobel Prize sperm bank,” opened in 1980, offering women the chance to conceive children using sperm from Nobel laureates, prodigies, athletes, and brilliant businessmen. For nearly two decades, it attracted attention and controversy before quietly closing in 1999—its founder dead, its records sealed, and the fates of its donors and children a mystery. In 2001, journalist David Plotz set out to uncover the truth behind this strange experiment. This film reveals the full, astonishing story of the Nobel Prize sperm bank and its founder’s daring attempt to engineer a superior human future.
