An erection might last indefinitely if it weren’t for chemicals called phosphodiesterases. They work at reversing the process that keeps the penis erect. Usually there is a balance between the chemicals that cause an erection and those that would return the penis to being flaccid. They pull in opposite directions with one dominating over the other in a perfect sequence that lets a man have an erection as long as it is needed.

Erectile dysfunction (sometimes called impotence) means that you cannot get or maintain a proper erection. There are several causes, the most common being due to a narrowing of the arteries that take blood to the penis. Sildenafil works by preventing the action of a chemical in your body, called phosphodiesterase type-5. Non-branded (generic) tablets of sildenafil are available on the NHS, but the brand Viagra® can only be prescribed on the NHS for men with erectile dysfunction resulting from certain medical conditions. This helps to widen (relax) blood vessels and improves the flow of blood to the penis following sexual stimulation.
