Viagra fuels STD surge

Divorce and the impotence drug Viagra are being blamed for a sharp rise in sexually transmitted diseases among British over-45s.
Cases of chlamydia are rising faster among the middle-aged than any other group.
Experts say divorcees who are returning to the dating scene may not consider themselves at risk of infections and assume medical warnings about safe sex are aimed only at the young.
The growth of anti-impotence drugs such as Viagra, Levitra and Cialis are also said to be increasing sexual activity.
It means that while cases of several infections are increasing among all age groups, they are rising particularly sharply among the over-45s.
