Can Viagra make your penis bigger? This depends on what you mean by bigger. Generally speaking, the answer is no: Viagra cannot make your penis permanently larger.

What Viagra – and the generic unbranded alternative, Sildenafil – can do, however, is support you to maintain a full erection for longer. Often when men are experiencing erectile dysfunction, their penises do not reach full size. Viagra can help with this, as it will improve blood flow to your penis – this increased blood flow engorges the penis more, resulting in a bigger and firmer erection.

No treatment can make your penis larger than it is. However, there are different ways to make it appear bigger. These include trimming your pubic hair or keeping fit.

What Are the Effects of Viagra?

Viagra remains the most popular treatment for erectile dysfunction (ED) in the world. 

Erections occur due to a complex combination of psychological and physical factors, in which the blood flow to the penis plays a crucial role. ED happens when blood is not flowing down there like it should be – and that’s where Viagra steps in. 

Viagra’s active ingredient, Sildenafil, is what is known as a PDE5 inhibitor, which tackles the enzymes that are associated with muscle contraction in your penis. The main effect of Sildenafil is to improve blood flow to your penis – allowing you to achieve and keep fuller erections.

But can Sildenafil make your penis bigger?

In this article, we’ll show you why the answer really depends on what you mean by “bigger”. Regardless, we’ll suggest some ways to become satisfied with your penis length – regardless of its size.

Can Viagra Make Your Penis Bigger?

Erect penises are larger than flaccid ones, of course. Viagra helps you achieve fuller erections by improving blood flow to your penis. In this way, yes, Viagra can technically make your penis bigger through its pharmacological activity – but you still require sexual stimulation to experience these effects. 

However, Viagra cannot permanently take your member beyond its natural size. Whilst it can allow you to achieve your full potential, it cannot increase this maximum itself. Unfortunately, there is not much that can. Your natural penis dimensions are something with which you should try to make peace. However, if you are concerned about your penis size, there is a chance that you are just not reaching your potential. ED can mean that your penis is not as large as it could be.

This is where Viagra can help to make you more satisfied with your size. By improving blood flow, the Sildenafil in Viagra can enable you to reach your peak.

What Does Viagra Do, and What Does it Not Do?

Viagra is a drug which is designed to help men who are experiencing ED to achieve an erection and sustain it for sexual intercourse. It is not, however, a miracle cure – and there are a few misunderstandings about what Viagra actually does.

Its active ingredient, Sildenafil, helps men to get erections, but it cannot do it alone. If you want to see a larger erection, you will have to get aroused first. The little blue pill isn’t an aphrodisiac and it won’t increase your sex drive. It will only help you out when you’re in the mood already.

Nor can Viagra make you last longer in bed in all cases. Sildenafil is not effective for premature ejaculation, nor for low libido. Viagra can help you last longer – but only if your stamina struggles because you usually lose your erection too quickly. 

Viagra will not solve all of your sexual problems. However, by working on your ED, it can do wonders for your sexual confidence. And that’s probably much better than having a larger penis anyway.

Are There Ways to Make Your Penis Bigger?

If Viagra can’t make your penis bigger, what can you do if you are dissatisfied with your size?

Firstly, you can try and gain a little bit of perspective. According to some studies, the average penis is 5.1 inches when erect, with the majority of men sitting within an inch either side. With 45% of men concerned about the size of their penis, it may be that yours isn’t so small at all. 

You may also want to remember that penis size has no relation to your ability to satisfy your partner. The same study found that 85% of women are satisfied with the size of their partner’s penis. It’s not the size, but how you use it that matters. 

If you really do want to see an increase in the size of your penis, drugs won’t help you, nor any special exercises you see around the internet. Sure, you could choose to have penile surgery – but this will probably cost you more money than it’s worth.

What you can do however is change the way your penis appears. Strategies like trimming back your pubic hair will make your penis look larger, as it won’t be hidden in the bush. The same principle applies to health and fitness: losing weight can help your penis look larger. General fitness and well-being can also improve your sex life – meaning that you might not care as much about the size.

Key Takeaways…

Sildenafil, the active ingredient in Viagra, can make your penis bigger – but maybe not in the way that you anticipated.

There are no scientific ways to increase the permanent size of your penis. What you’ve got is all you’re going to get, unfortunately – no amount of stretching or special pills is going to help.

What Viagra can do is ensure your penis reaches its full potential size. Many men with ED cannot achieve full erections, meaning that their penises are not as large as they could be. Viagra can help you feel satisfied again – in more ways than one.
