The artificial insemination explanation is a very good one. Surely you have heard of Lance Armstrong, the great American cyclist? Here in Europe we were awestruck at his performance in Tour de France, a gruelling two-week race all around France where the cyclists race each other up and down steep mountains. Lance Armstrong won this race seven years in a row. Anyway, before he had won Tour de France even once, he was diagnosed with testicle cancer. The treatment he had to undergo rendered him sterile. But he saved some of his sperm, and now he is the father of three children. Certainly Clark Kent wouldn't have had the same reason as Lance Armstrong to extract and deep-freeze some of his sperm, but he might have done it, all the same.
Anyway, I would love to read this story!
