POOR SHERYL CROW

In a bluntly worded editorial with ..., Dr. Steven Schrader, a reproductive health expert who studies cycling at the National Institute for Occupational Safety and Health, said he believed that it was no longer a question of "whether or not bicycle riding on a saddle causes erectile dysfunction."

Instead, he said in an interview, "The question is, What are we going to do about it?"

The studies, by researchers at Boston University and in Italy, found that the more a person rides, the greater the risk of impotence or loss of libido. And researchers in Austria have found that many mountain bikers experience saddle-related trauma that leads to small calcified masses inside the scrotum.

This does not mean that people should stop cycling, Dr. Schrader said.
