Athletes looking for a performance boost appear to be turning to a little blue pill more usually taken for its off-the-field benefits: Viagra.
But experts are divided over whether it actually offers athletes an edge.
Some sports authorities say the drug is now finding a following among athletes. It isn't clear how many might be taking it in hopes of improving athletic performance.
It also has attracted the attention of the World Anti-Doping Agency. The agency is studying Viagra's effects in athletes, but hasn't yet banned it. Viagra is not on the International Olympic Committee's list of prohibited drugs, so athletes can take it at the Beijing Olympics.
