Do Penis Pumps Work For Size Gains? The Truth About Bigger Girth, Better Boners & Pump Myths

Marco using a penis pump, exploring if penis pumps really work for size gains & better erections.

Can a plastic tube really turn your dong into King Kong, or is it just a bunch of hot air? Google searches for “do penis pumps work” have surged by ~60% in recent years—clearly, we guys are curious.


Clinical data suggests that penis pumps help up to 9 out of 10 men with erectile dysfunction achieve and maintain an erection—clearly, real results matter. Keep reading because if you’re gonna stick your dick in a tube, you deserve to know if it’s science… or suction-based sorcery.

In this article, we'll cover:

  • Discover how penis pumps boost size (temporarily) & improve erections.
  • Hear real testimonials from guys who’ve tried them—good, bad & hilarious.
  • Uncover the biggest pump myths & what actually works (and who it’s for).

Do Penis Pumps Actually Work? Yes—Here’s The Science Behind Why They Do

Marco & Ivy exploring anatomy charts, discussing the science behind how penis pumps actually work.
Short answer: Yes. Penis pumps (a.k.a. vacuum erection devices) absolutely can help you get harder and slightly bigger—at least temporarily. But let’s pump the brakes and break down the science behind how and why these gadgets actually work.

So, Do Penis Pumps Really Work?

When using a penis pump, you place your penis inside a cylindrical tube, then pump to create a vacuum effect. That suction draws blood in, giving you a firmer, thicker erection. It makes your penis look bigger temporarily, and they’re beneficial for erectile dysfunction (ED) and recovery after radical prostatectomy. Just don’t expect miracle growth or permanent results.

Here’s What Science Says

  • Short-term Size Gains Are Real
    A BJU International study tested vacuum pumps on 37 men with shorter penises (<10 cm). After 6 months of regular use, the average length increased from 7.6 cm to 7.9 cm. That’s just 3 mm. Verdict? Pumps do work, but the gains are minimal, not miraculous for elongation.
  • Permanent Gains? Not Much
    A 6-month trial in the British Journal of Urology International showed minimal long-term size increase even with daily use. The study found that while gains weren’t permanent or dramatic, vacuum pumps can temporarily boost length and confidence for men seeking visible results.
  • Effective As An ED Treatment
    The American Urological Association backs penis pumps as a legit ED treatment—especially if you want to avoid pills. Their 2018 guidelines say men should be told about vacuum devices, including pros and cons. Bottom line: they’re a real, effective option for managing ED.
  • Helps Post-Surgery Recovery
    Research in European Urology shows that pumps help preserve penile length and function after radical prostatectomy. Early VED use boosts blood flow and prevents tissue damage—key for better recovery and erections.
If permanent penis enlargement is your main goal, talk to a healthcare professional about other methods (penile implants, penile injections, penis extenders or penis enlargement surgery)—just know those come with their own baggage.

Speaking of pumping wisely—let’s see if real dudes think it's a "stroke" of genius or just blowing hot air.

What Real Men Are Saying After Using A Penis Pump

Nothing beats hearing it straight from the guys who’ve tried it, right? I scoured forums and comments to see how real users feel about their penis pump experiences. Spoiler: results vary, but there are some common sexual satisfaction themes. Here’s a snapshot of what men are saying:
Marco demonstrating penis pump use, representing real men's testimonials about penis pump experiences.
I tried one for about a month. It didn’t increase my length, it did increase my girth just a little bit although the gain was temporary. It made my erections less firm after pumping, which was disappointing. r/AskMen
I used a really good (not cheap) pump consistently, and I gained only about half an inch in length and half an inch in girth. It did improve my erection hardness, though. – Quora User
I have used a pump with a ring for many years. My girth has increased by over an inch permanently. I still use it, maybe 10 minutes a day, for erectile dysfunction maintenance. – @2gpowell Youtube Comment

The short answer is: slightly, perhaps 5%, but this isn’t really permanent. – r/erectiledysfunction

In my experience, it is more of a sex toy than a medical device. – r/erectiledysfunction

I used a Vacurect pump for post-op rehab. It was recommended by my urologist, and I was pretty happy with how it worked. – r/erectiledysfunction/

As you can see, experiences differ. Some men see temporary girth gains and enjoy the fuller feeling, but no length change. Others claim modest permanent improvements after long-term use (especially in girth). And a few note downsides like slightly softer natural erections if they over-pumped or relied too much on the device.

Bottom line? Penis pumps won't make you a legend overnight—but they're pretty damn good at turning your dick into a temporary superhero.

Now you've got the word on the street—time to deflate these myths quicker than your erection post-pump.

Andrew’s Expert Insights On Penis Pump Safety & Results—Myths vs. Facts

Marco & Ivy intimately discussing penis pump myths vs. facts in bed.

Time to bust some myths! As someone who’s researched and tested these things, I’ve heard all sorts of wild claims and fears about penis pumps. Let’s separate the facts from the fiction:

Myth #1 – Penis Pumps Are Just Sex Toys

Guys often see the vacuum pump as just another kinky gadget from a sex store—something fun, but not serious.

The Fact

Doctors have used vacuum erection devices (VED) for decades as legit medical gear to stimulate blood flow and improve erections. Think of them like your dick’s personal trainer: playful, sure—but seriously effective for sexual health.

Myth #2 – You Should Pump Until It Hurts (That Means It’s Working)

Some guys think cranking up the pressure gets them faster results—like pain is proof that their penis size is increasing.

The Fact

Pain means you're pushing past the limit—and risking real damage. Too much pressure can tear the tunica albuginea, leading to venous leakage, a hidden cause of weak erections. Most penis pumps are designed to encourage blood flow, not destroy tissue. Stick to FDA-approved devices and follow the manufacturer’s instructions. And if you're using a rubber tension ring, don't keep it on longer than 30 minutes—or you'll cut off more than just circulation.

Myth #3 – Using A Pump Can Permanently Damage Your Penis

Horror stories circulate about bruised, battered penises, and even trapped semen causing damage. Sounds terrifying, right?

The Fact

Penis pumps are generally safe when used correctly—follow guidelines, use a vacuum limiter, and avoid marathon sessions. Your dick isn’t gonna explode; don’t go rogue with insane pressure or endless pumping marathons.

Myth #4 – Pumps Only Work For Older Men Or Guys With ED

Some dudes think pumps are just for older men dealing with prostate cancer or those desperate to cure ED when oral medications fail.

The Fact

Young, healthy guys use pumps too—it’s a non-invasive way to enhance erectile function and sexual confidence. A pump at the base of your penis can level up your bedroom game, regardless of age or existing ED issues.

Myth #5 – Penis Pumps Work The Same For Everyone

A lot of guys assume all penis pumps sold online will deliver the same results for every man.

The Fact

Nope. Your natural erection quality, anatomy, and how your body responds to vacuum pressure affect results. Some men may need a custom-sized tension ring, while others with ED or post-surgical procedures like prostate removal might need pumps as part of a full treatment option. Penis pumps aren't one of those advertised penis enlargement methods promising miracles—it’s a tool. Use it right.

Remember: Your dick deserves the VIP treatment—don’t cheap out on gear or technique. Pump smart, pump safe, and keep your VIP (Very Important Penis) happy.

Got questions still buzzing around your head (or other places)? Let's tackle 'em.

Frequently Asked Questions

Pump questions still floating around your head? Relax—I’ve heard 'em all (trust me). Here are quick answers every guy needs.

Can you use a penis pump if you already take ED meds?

Absolutely—you can mix penis pumps with other ED treatments. Meds improve your penile blood flow, and the pump physically draws blood into your penis, making your erection firm and impressive. But heads up: if you're on blood thinners, chat with your doc first to avoid bruises that nobody ordered.

Can a penis pump be used for general male health or maintenance?

Yep, pumps aren't just for getting laid—they can help maintain healthy erections, especially after issues like prostate surgery. Regular use supports tissue health and keeps your pipes (and even your urinary tract) in good shape. Think of it like doing push-ups for your penis: preventive maintenance is smart.

Do penis pumps improve erection quality long-term?

They definitely can help, but won’t fix the deeper underlying causes of ED. Consistent pumping improves penile blood flow over time, which supports better erections. Still, pumps work best alongside other treatments like lifestyle changes, because even your dick appreciates teamwork.

Can a battery-powered penis pump give better results than a manual one?

For many men, yes. A battery-powered pump delivers steady, consistent pressure that’s hard to replicate manually, especially for beginners. That steady vacuum helps men achieve fuller erections with less effort and often feels more natural during use. Just make sure it’s quality-built and from a trusted source so it doesn’t conk out mid-pump.

Can using a penis pump make sex feel better—for both you and your partner?

Absolutely. By increasing blood flow, a pump makes your penis larger, firmer, and more sensitive—which often means stronger orgasms and more satisfying penetrative sex. Used right, a pump helps both you and her enjoy more intense sexual activity without needing pills or injections.
