Brave New Birth Control

By CHRISTOPHER JOHN FARLEY

Surprisingly, Ross Perot has other interests besides being a thorn in Bill Clinton's side. He is, for example, using his money to dabble in contraception. The Perot Group is one of the key financial backers of Zonagen, & Inc., a biotechnology firm based in The Woodlands, Texas, that is seeking to develop a reversible human contraceptive vaccine. The company is currently refining a vaccine that sterilizes female cats and dogs. Last month the firm attracted $7.4 million from investors in the first public offering of its stock.
