Will Viagra Make My Penis Bigger?


Yes, we know Viagra – aka Sildenafil – will support a stronger erection, but will it actually make it larger? We explore…

The Big Question

For thousands of years, man has pondered the Big Questions: What is the meaning of life? Are we alone in the universe? Does God exist?

As we have searched for answers to these great mysteries, we have also obsessed over another, arguably more pressing question: How can man make his penis bigger?

Let’s face it: a lot of men are hung up on how well-hung they are. The ubiquity and accessibility of porn doesn’t help; but man’s penis-size-centric mindset probably goes back way, way further than the invention of erotic visual media, and we’re sure there were plenty of neanderthals who felt a pang of inadequacy when a better equipped caveman crossed his path.

Fast forward to the present day, and these insecurities have become something of a cultural obsession, spawning all manner of pills, potions, contraptions that resemble medieval torture devices, stretching techniques, and an assortment of invasive surgeries we’d rather not think about, that all claim to make one’s penis bigger. 

Even Sildenafil, the active ingredient in Viagra, has been linked to penis enlargement. Wrongly linked, to be precise.

Can Viagra Help?

Sildenafil (Viagra) is many things: for a start, it was the first treatment to be clinically approved to treat erectile dysfunction. Secondly, it is safe and effective, having been extensively trialled in over 47,000 patients. Thirdly, eighty percent of men who take Sildenafil achieve the intended results; or, to put it even more clearly, it supports 80% of men with stronger erections. 

So, finally, Sildenafil helps men experiencing erectile dysfunction to make the absolute most of what God—who may or may not exist: see ‘Big Questions’ above—gave them.

What Sildenafil is not is a magic pill that will permanently increase your penis size, whether you’re hard, soft or in the highly desired midpoint ideal for walking around naked in front of your partner.

Sildenafil works by inhibiting an enzyme known as PDE5, which is responsible for the muscle contraction within the blood vessels, including ones supplying the penis. When taken, Sildenafil allows the blood vessels to relax and expand, meaning blood can flow freely into the penis, resulting in a firm, proud erection. So yes, it will make your penis bigger, but only in the sense that it will take it from soft to hard (providing you’re aroused. Sildenafil is not an ‘on/off’ switch for your penis).


This means you should only take Sildenafil if you’re having problems achieving and maintaining a strong erection. It’s clinically proven and used by millions of men worldwide.
