Viagra may harm men's fertility, report warns

Extract from the Sunday Telegraph:

"The anti-impotence drug Viagra could harm men's fertility, scientists have warned.

New research suggests that the drug can damage sperm and so prevent some men from starting a family.

The findings mean that young men who take the drug recreationally could be damaging their chances of starting a family.

Likewise, fertility clinics that prescribe the drug to help men produce sperm could be preventing couples from getting pregnant.

The research was led by Dr David Glenn, a consultant gynaecologist at Queen's University Belfast, and will be published in the journal Fertility and Sterility."
