Mr. Adam

After a devastating nuclear accident, all men on Earth are rendered sterile, even the unborn in the womb. Ten months later, a doctor delivers a perfectly healthy baby girl, and it's soon discovered that the child's father, who has the surname Adam, was miles under the surface of Earth inside an iron mine during the explosion. It would appear that this Mr. Adam just became a lot more popular.
