I’m sure I’m not the only one who opens her email inbox in the morning only to find it filled to bursting point with spam ads for Viagra and other forms of medication that I neither need nor want. But even though I’m not interested in Viagra, I accept that for some it’s been a godsend. But do you now how it works?

First of all, in order to understand how Viagra works, you need to understand how the penis works. Because it doesn’t have any muscles it’s dependent on pressure from blood flowing in to it in order to make it move (become erect). When the blood rushes into it, it’s sort of like air being blown in.

The blood flows into the penis through two arteries and it’s when one remains constricted—as it is while it’s limp in order to stop blood flowing in—that erection problems arise (otherwise known as penile dysfunction). Enter Viagra whose job it is to open the artery and allow blood to pass through.

Viagra makes sure that the penis receives the blood it needs by acting on the tissue surrounding the arteries when a man becomes aroused. Exactly how it does this is far too scientific to answer in a short blog post but it’s generally enough to know that it won’t cause erections amongst men who aren’t aroused, a fear that many appear to have. It reacts with enzymes that are released during arousal so there’s really no reason to think that if you take Viagra, you’ll end up walking around with a boner all day.

One final word. If you are thinking about using Viagra or a similar drug, speak to your GP first. Ordering drugs over the Internet is never a safe way of going about dealing with health matters.
