Viagra Corner: Despatches from the Frontiers of Medicine

IMPOTENCE MYTHS are the same the world over, according to a global survey of men's attitudes to sexual dysfunction, commissioned by Pfizer, the manufacturer of Viagra.

A poll of more than 4,000 men from 10 countries today showed that half the respondents in each country thought impotence was caused by psychological factors such as stress and anxiety.

Fewer than 25 per cent correctly identified high blood pressure and diabetes as two of the most common conditions behind impotence. One in three thought impotence was a natural consequence of ageing. Alcohol was cited as the leading cause of impotence by Germans, Moroccans and Swedes.
