We need to talk about size. Penis size, to be precise. And it’s something that a number of men are concerned about. 

We need to talk about size. Penis size, to be precise. And it’s something that a number of men are concerned about. 

Some men may even get so anxious about penis size that it can lead to erectile dysfunction. However, if you look at the research, most men have no reason to worry about their size. (More on that soon!)

Nevertheless, it’s often thought that bigger is better. And that very thought may lead you down the path of wanting to explore penis enlargement products — specifically, penis growth pills. 

But do these pills actually work — and are they safe? Let’s dig in. 

A Word on Penis Size

Worried about your size down south? The research may make you feel better.

One published in the British Journal of Urology International (BUJI), reports that the average length of a flaccid penis is a smidge over 3.6 inches. As for an erect penis, the average length is just over 5 inches.

Wondering what women think about penis size? In one small study, researchers asked women about their penis size preferences. 

What they found was that for a long-term relationship, women reported preferring only a slightly larger-than-average penis.

Even with this info in mind, you may still experience some anxiety around penis size. And there’s actually a diagnosis centered around that anxiety: small penis syndrome.

For some men, that anxiety may lead you down the road of wanting to explore penis growth pills. 

What Are Penis Growth Pills and Do They Work? 

Penis growth pills are also sometimes called penis enlargement pills. Generally speaking, these types of pills claim to increase the size of the penis, either while flaccid or erect. 

Though certain male enhancement products may work to temporarily increase the size of your erection, there isn’t much you can safely do to permanently enlarge your penis.

These pills often contain vitamins, minerals, herbs or hormones that claim to enlarge the penis. But, here’s the problem: They’re unregulated and lack any research having to do with their safety or efficacy. 

In fact, per an FDA warning, it’s important to be very careful when it comes to enhancement supplements. In testing, the FDA found many pills that contained potentially harmful ingredients that weren’t listed on the labels. 

These ingredients could cause side effects or potentially interact with other medications you may be taking. 

As for whether or not penis growth pills work, there’s simply no conclusive evidence. But you should know that there is nothing on the market that can permanently enlarge your penis.

Do Traction Devices Work? 

Along the same lines of penis growth pills, traction devices make the promise of being able to elongate the penis. However, the evidence for penile-lengthening traction devices isn’t much better. 

Penile traction devices (sometimes called penis extenders) stretch tissue in the penis to increase length.

But do they work? One small study on 15 men looked at a specific penile traction device called the Andro-Penis®

It found the device could add 0.9 inches to the length of a flaccid penis after six months of use of at least four hours per day. 

Let’s break that down: According to this study you’d have to spend at least 720 hours with your penis in a traction device to gain a little over half an inch. 

RestorX® is a newer penile traction device on the market. It’s actually meant to treat Peyronie’s disease (PD), a condition where scar tissue builds up in the penis and causes it to bend or become indented during erections. 

It also claims to be able to help men with penis lengthening in men with chronic diseases like diabetes. 

But, does it work? One clinical trial did find that men dealing with Peyronie’s Disease who used it for 30 minutes a day for either six months or nine months did report improvement. 

However, there’s no research on men not dealing with PD as to whether it can work as a lengthening treatment.

A Word on Penis Surgery

An invasive, higher risk option to lengthen your penis is surgery. Penis lengthening surgery entails severing a suspensory ligament that attaches the penis to the pubic bone. 

Yup, ouch. 

By doing this, the penis hangs lower. Skin from the abdomen is then placed onto the shaft of the penis to make up for the new length.

But the procedure doesn’t end after the surgery. During recovery, men are required to suspend weights from their penis throughout the day. The weights prevent your body from healing the cut ligaments and reattaching them.

Here’s the thing: One research review found that some surgeries increased penis length by two centimeters — yet the same review also stated that the men who seek such surgeries typically have a normal penis size.

It’s also important to note that these surgeries have generally been deemed too risky to be recommended.

What Could Help Penis Size 

Wondering what you can do about your penis size? Here are a few things to consider: 

  • Lose Excess Weight (if Needed): If you have a beer gut, your penis may look smaller than it actually is. Regular exercise and healthy eating can make a big difference. 

  • Chat with your partner: If you’re worried about how your partner views your penis, talk to them about it! It can be uncomfortable to get the conversation started, but you’ll likely feel better getting it out in the open. Plus, they will be able to reassure you and, together, you can talk about pleasurable ways to find even more enjoyment in the bedroom. 

  • Talk to a healthcare professional: A healthcare pro may be able to help you understand your penis is average. They can also talk to you about whether there are any enlargement tools or ED treatments that could work for you.

Penis Growth Pill Alternatives

If you’re still asking yourself, do any penis growth or enhancement pills work? There’s just not enough evidence to definitively say. More importantly, there is evidence that shows they’re not safe to take. 

That means, you really should avoid these types of enhancement supplements. 

Similarly, there’s no scientific evidence to support penile traction devices as a solution. And penis enlargement surgery has been deemed extremely risky. Because of this, these types of surgical procedures should be avoided. 

It's worth remembering that most of these things may not even make your penis larger — and if they do, it's minimal. 

It’s most important to know that you likely have nothing to worry about when it comes to penis size. As mentioned above, the average size of an erect penis is just over five inches. 

If you’d like to discuss penis enhancement options or find out if you're dealing with health conditions that could affect penis size, consider making an appointment with a healthcare provider

He or she will be able to assess the situation and talk to you about treatment options that do not put your health at risk — and help you decide if you need treatment in the first place.
