BBC地平线：天才精子银行

Millionaire optometrist Robert Graham believed that many intellectuals were dying childless, yet less-intelligent people were constantly reproducing. He wanted to bring thousands of geniuses into the world to ensure the future of the human race. In the early 1980s, he established a Repository for Germinal Choice - a sperm bank stocked full of 'donations' solicited from some of the world's most brilliant men; and he began with Nobel Laureates. This is the story of an endeavor that many agree laid the foundations for modern sperm banks.
