Best Penis Extender in 2021

In a crowded field, what’s the best penis extender for you? We put them to the test and then broke down the pros, cons, and all major considerations

Last Updated: Apr 29, 2021

best penis extender guide

If you’re reading this, you likely wish that your penis was larger. It may not surprise you that the majority of men aren’t satisfied by the size of their penises. Why should people be content with average if there are ways to make a penis better than average?

All of this begs the question: are there legitimate, proven ways to make a penis bigger? And if so, are they safe as well as effective? Will they break your bank account or are they affordable? How long will it take to enlarge your penis? Can you trust a particular company to deliver the product discreetly?

The good news is that there are safe ways to make your penis larger (as well as straighter, for men with Peyronie’s who cope with curvature that makes sex more difficult or painful). We’ve tested the devices and evaluated them in comparison to one another. Here is our guide to the best penis extenders in 2021 – devices that actually work.

For those in a hurry, here are our top recommendations without further ado:

Summary of recommendations for best penis extender

Our Top Choice

Quick Extender Pro

Quick Extender Pro is our overall winner this year thanks to its combination of affordability, power, and comfort.

High tension strength and comfort make it capable of delivering relatively fast results. This isn’t the most inconspicuous or most comfortable on the market, but it’s the most affordable. For most people, we believe it’s the best value.

Why you should trust us

Innerbody Research recently celebrated its 20-year anniversary online. Over the past two decades, we have helped tens of millions of readers make more informed decisions involving staying healthy and living healthier lifestyles.

This guide, like all medical-related content on this website, was thoroughly vetted by one or more members of our Medical Review Board for medical accuracy. We extensively test, experience, and evaluate each health product we review. We try our best to give you unbiased, marketing-jargon-free descriptions of all the at-home health products evaluated based on the latest scientific evidence and medical standards.

What is a penis extender?

Studies tell us that 95% of men have erections whose length is less than 6.3 inches, and a full 85% of men have penises that fall within an inch of average length when erect. (Average size when erect is 5.16 inches long and 4.59 inches in circumference.) The many men who are within an inch shy of average size or whose partners have admitted a lack of sexual satisfaction understandably look for safe ways to achieve enlargement.

In the broader world of penis enlargement, approaches commonly fall under three different categories – surgery, substances, and devices. Penis extenders fall under that third category of products. All of the penis extenders in this guide rely on a proven method of penis enlargement called traction, or penile traction therapy (PTT).

Traction as a method of enlargement

The easiest way to understand penis traction is by thinking of muscle-building. When people lift weights or work out to build muscle, the exercise causes very tiny tears in our muscle tissue. The body repairs these microtears with cell replication. This repair process is what builds our muscles.

In essence, this is the concept behind the effectiveness of traction in enlarging the penis. A traction device applies pressure to stretch the tissues of the penis gradually but persistently for periods of time. This pressure causes microtears in the tissues of your penis, which the body then repairs similarly to how it repairs and “builds” muscle after a proper workout. Gradually, this translates to growth in penis size.

As the body repairs microtears in the corpora cavernosa – the spongy tissue in the shaft that collects blood – men find their erections gaining noticeable size and strength. Clinical studies confirm that wearing these devices produces actual results for men hoping to enlarge their penises both in length and girth.

Importantly, the growth in size that some men see within the first couple weeks of using traction-based penis extenders may not be permanent. But studies prove that the gains become permanent after using a traction device for months rather than weeks. Once you have used a device for several months, you can stop when satisfied with your size and know that the gains are permanent.

How does traction compare to the alternative approaches to penis enlargement? It turns out, the traction method used in penis extenders compares very favorably, as you’ll read later in this guide.

A broad look at the best penis extenders on the market

The Quick Extender Pro is our editor’s choice as the best penis extender for most men in 2021. It’s also one of the most popular products among the men we’ve interviewed in the process of making this guide. However, other options may be a better fit for you depending on lifestyle, goals, and budget.

Here’s a comparison of the best devices we tested for this guide, with more details below. All of these penis extenders rely on penis traction and produce desired results when used as intended and for the necessary length of time.

Our top pick in 2021: Quick Extender Pro

quick extender pro

What do paring knives and penis extenders have in common? Hopefully not much, but there is one thing: sometimes the least expensive choice can be the best for most people.

The market for penis extenders is crowded and not all devices are the same. We tested and evaluated penis extenders based on price, comfort, safety, tension strength, and convenience. This helped us form an overall picture of value and usability. We also gathered opinions from numerous customers who gave us their own reviews of the penis extenders as well, in order for us to develop a picture of broad user satisfaction and success.

Based on our testing and analysis, Quick Extender Pro gives the best combination of strength, comfort, affordability, and fast results.

Pros

  • Most affordable penis extender that impressed us
  • More tension strength than all but one of our recommendations
  • Capable of the achieving the fastest results
  • Effective for men correcting mild to moderate Peyronie’s curvature
  • Lightweight, which enhances comfort

Cons

  • Not compatible with overnight wearing
  • Not as comfortable as Phallosan Forte or PeniMaster Pro

First, let’s consider strength. The Quick Extender Pro is capable of greater tension than almost all of the high-quality devices we tested. At 4000g tension strength, only a very expensive combination of Phallosan Forte products would exceed it. This high amount of tension strength and the classic approach (sans vacuum) make this our recommendation for correcting mild to moderate Peyronie’s curvature as well. You could pay more than twice this amount for RestoreX.

In terms of comfort, the Quick Extender Pro doesn’t disappoint. You could buy a more luxurious, comfortable penis extender. Its double-strap innovation combined with comfort padding allows for longer wear times without discomfort, which in turn enables faster enlargement. Though one of the strongest penis extenders on the market, the Quick Extender Pro is lightweight and small enough to be worn pretty discreetly under baggy clothing in very low-activity public settings as well, in a pinch – something that isn’t the case for others.

You can also breathe easily while buying this device, because Quick Extender Pro comes with a six-month money-back guarantee if, for any reason, you’re not satisfied with the device – regardless of the number of hours you used it. We find this preferable to the money-back return policies of other companies, some of which require proof of ineffectiveness (even asking for before/after pictures in some cases).

Quick Extender Pro offers several products at different price points. Right now, you can buy a high-quality, rod-based penis extender from this company for less than comparable products elsewhere, making it an excellent value. It’s unclear how long Quick Extender Pro will sustain these low prices.

Below is a quick breakdown of available products. For most people, our top choice is the Deluxe Standard Edition.

Considerations when choosing a penis extender

The best penis extender for you might not be our top pick, but a different device, depending on a few factors in your life. Here are some major considerations.

Speed

How quickly do you want results? Some penis extenders are built to deliver results after 6-12 months of gradual, low-impact usage. Other companies design their devices with greater tension strength, allowing for more intensive use and faster results (as long as the device is comfortable enough to wear for long periods). Your preference will depend on how quickly you feel you need results, balanced with your availability to wear the device for what could amount to an extended period each day. Finding the right balance for you will be key to your contentment with the penis extender. And of course, you must listen to your body as you use a penis extender. If you’re experiencing discomfort, it’s a signal from your body that you need to slow down and reassess. Do not ignore discomfort, because when used properly these devices shouldn’t cause discomfort.

Comfort

No matter what device you choose, you ought to wear it as instructed, for extended periods. Comfort becomes a big consideration. Some companies upsell based on comfort and packages that include additional features to help you maintain comfort. Like it or not, these packages are often well worth it, which is why we often recommend you consider them above the more entry-level packages. Comfort that doesn’t sacrifice strength allows you to wear the device without issue for longer periods of time, which in turn speeds up the process of penis enlargement.

Budget

Penis extenders aren’t all priced the same. If you’re on a tight budget, you may well want to ignore what we just said about comfort and opt for the device package with the lowest price tag. If that’s a necessity, rest assured that you could choose any of the entry-level options from any company in this guide and be well-served by it. All of these products, at whatever price level, are safe and effective.

Design

When it comes to products we use in and around personal areas, appearance does matter. This is because psychology plays an important role in how well many of us adhere to a new routine, in addition to how well we can address and treat the underlying concerns here. If you feel a connection to a particular device aesthetically and it strikes a good note with you, this isn’t something to ignore.

Convenience

Life gets busy and the prospects of wearing a penis extender may seem daunting depending on where and how you work and how much non-active time you can find each day. Penis extenders vary in the level of convenience they afford you. Heavier and bulkier models may not be suitable for wearing under much clothing or for long periods. Meanwhile, lightweight and sleeker extenders could be worn under clothing quite discreetly. Still others, like the Phallosan Forte, can be worn more safely in bed while you sleep.

Phallosan Forte: Overall runner-up and tops for convenience

The Phallosan Forte is our runner-up choice for best penis extender and stands out in a few ways from competitors. Its penis extender relies on both strap-based and vacuum mechanisms. For some of you, it should be your top choice.

Pros

  • Can be worn discreetly in public
  • Can be worn overnight
  • Very comfortable

Cons

  • Higher cost
  • No competitive money-back guarantee policy

Combining rigid belt methods with a vacuum chamber to hold the glans in comfort during use, the Phallosan Forte is best-suited for men who want a comfortable enlargement process and don’t mind it taking a couple of months longer if their schedule doesn’t permit long daily usage. This penis extender is a very smart option for men who can wear the device for extended periods. This one may be ideal for you if you have a non-active job since the Phallosan Forte is discreet and low-profile under clothing. But for many men, it’s suitable for use while sleeping, too.

Our testers were impressed by the Phallosan Forte. If you can afford it, we believe you won’t be disappointed. But the higher cost and lack of a competitive money-back return policy prevent it from earning our top recommendation for most men in our 2021 rankings.

The overnight treatment option is tantalizing for obvious reasons. Many penis extenders just don’t do well in this scenario either because of a bulkier, cumbersome design or because they become painful when a nighttime erection happens. We found the Phallosan Forte to excel in overnight wear. It’s capable of delivering this level of convenience for a couple of design reasons:

  • Phallosan Forte will adjust in real time to an erection, preventing uncomfortable issues that arise with other penis extenders.
  • The way the device apparatus hugs the side of the waist makes things less frustrating for those of us who toss and turn a bit in the night.

This combination of factors allows many people to relegate some of their penis extender time to the wee hours – though that may not be ideal for guys who tend to make a trip to the bathroom in the middle of the night.

The way the Phallosan Forte rests along your side as you wear it under clothing also makes it slightly more discreet in our experience than other penis extenders, even the PeniMaster (which is also fairly discreet, by the way). Thanks to this and the overnight option, the Phallosan Forte is our choice for the most convenient penis extender in 2021 – if your wallet can handle it, that is.

Part of the reason why the Phallosan Forte lends itself to more gradual results is that its tension is lower than that of Quick Extender Pro, for instance – unless you spend an extra $120 on the Phallosan Plus+ add-on that grants you additional tension and stability. Combined with the Phallosan Plus+ addition, you can get up to 4800g of pressure, which is even more than Quick Extender Pro. Based on our testing and analysis, we believe most people will not need 4800g, which is why we recommend you try Phallosan Forte on its own before considering the additional investment. The Phallosan Forte, by itself, costs $379 – already considerably more than our top pick.

But if you’ve got the budget and the hours available to wear it, or are willing to wear it overnight, the Phallosan Forte is comfortable enough to deliver long treatment sessions, making up for its slightly lower out-of-the-box tension strength so that you don’t wait longer for results. And if wearing it overnight is important, this penis extender might just be your ideal choice and well worth the extra cost.

SizeGenetics

Pros

  • Adjustable comfort settings
  • Power to achieve noticeable growth in months

Cons

  • Higher cost than some competitors is hard to justify
  • Heavier than other penis extenders

Made from only medical-grade components, SizeGenetics is one of the most trusted names in penis extenders. Just like MaleEdge and JES Extender, a SizeGenetics extender delivers up to 2800g of tension strength, making it an effective penis traction device. When it comes to comfort, SizeGenetics aims to please with 16 different comfort settings.

The major downside we discovered with SizeGenetics is the weight of the device. Although SizeGenetics enables you to fine-tune with all of those settings, this penis extender is one of the heavier devices we tested. The added weight, as compared to Quick Extender Pro or MaleEdge, is noticeable.

You may never experience any inconvenience or discomfort associated with its weight; that depends on the length of your sessions wearing it. In fact, even if you eventually do experience discomfort, you might not know what’s causing it. But our testers, in addition to other customers, felt that at the upper lengths of hourly wear each day, the added weight of the penis extender became a source of discomfort and occasionally frustrated people who tried wearing it under different types of clothing.

With penis extenders, lighter is definitely better in our opinion, as long as the device doesn’t sacrifice tension strength.

PeniMaster Pro

Pros

  • Innovative combination of rigid and vacuum mechanics
  • Less expensive than Phallosan Forte
  • Can be worn comfortably for long periods
  • Can be worn overnight if necessary

Cons

  • The lower tension strength creates more gradual growth
  • More expensive than strictly rod-and-strap penis extenders

What makes the PeniMaster Pro appealing to many men is the combination of comfort and affordability. While not as affordable as competitors like Quick Extender Pro, it is less expensive than its closest functional rival, Phallosan Forte (both utilizing a combination of vacuum and rod/strap-based traction techniques). This should make PeniMaster Pro a contender for your business.

In comfort, it rivals the Phallosan Forte, but at a lower cost. Aside from some normal tingling, the PeniMaster Pro is a smooth experience compared to the amount of stretch sensation that other penis extenders cause.

You have the option of using PeniMaster Pro in a rod-based or a belt-based system, depending on your preference. Our testers found the rod-based option slightly less fussy, but the belts do provide varied directions in the traction therapy to avoid the possibility of fatigue from repetitive exercise.

To learn more, check out our full review of PeniMaster Pro.

What are the tradeoffs?

For one thing, PeniMaster Pro is not as easy to start using as other penis extenders, in our testing. Plan to spend some time figuring it out or watching the instructional video. We strongly recommend the video because the device isn’t quite as intuitive as others.

A lower tension strength generally translates to slower treatment times. If you only have a small set of numbers available for wearing it each day and you find overnight use doesn’t work well for you – we generally don’t recommend it with PeniMaster Pro and neither does the company, as a matter of fact – the lower tension strength could mean your results come later than with other penis extenders that have higher tension capability.

However, the beauty of PeniMaster Pro and Phallosan Forte is that they’re so comfortable that you can wear them for longer durations each day without discomfort. The comfort, therefore, offsets the lower tension in the case of PeniMaster, as long as you have the time in your schedule to accommodate longer wearing. (For those who work at home either during the pandemic or always, this won’t be a problem at all.)

PeniMaster can be worn overnight while you sleep, if necessary, though our experience suggests that the Phallosan Forte has a competitive edge in that scenario due to a less cumbersome device under the covers. We would recommend sticking to daytime usage with the PeniMaster Pro.

One of our testers echoed the sentiments of some customers who find the PeniMaster Pro not quite as ideal as the Phallosan Forte when trying to wear it discreetly under clothing; these men felt that the only good position for it was straight upward, as opposed to downward or to the side (two options that PeniMaster contends are suitable). Most testers found it to work just fine in a downward or diagonal position.

Word of caution

If you decide that PeniMaster Pro is the right device for you, don’t buy just the “PeniMaster Pro Basic” on its website because this includes only the bulb that attaches to your glans. By itself, this bulb will not achieve your goals of penis enlargement; it’s intended to be used either with PeniMaster’s rod or belt system or a different weight system of your own devising (something that isn’t clear enough on the website, in our opinion).

To buy a package that will achieve penis enlargement out of the box, you need to opt for the belt or rod expander systems, both of which include a PeniMaster Pro bulb; the complete set, which includes both rod and belt options; or the PeniMaster Classic, which includes only a traditional rod-based penis extender without the PeniMaster Pro glans bulb attachment.

MaleEdge

Pros

  • Very lightweight
  • Straightforward mechanics
  • Budget-friendly
  • Attractive, friendly design
  • Remembers its tension settings precisely

Cons

  • During adjustments, the device feels a bit uneasy and cheap
  • Less powerful than Quick Extender Pro
  • Not quite as comfortable as others

MaleEdge occupies an interesting position in our assessment. It’s one of the most budget-friendly options available. Its power matches that of JES Extender and SizeGenetics, ensuring that MaleEdge can deliver results for you after several months of use as directed.

Design-wise, MaleEdge offers a penis extender that’s easy on the eyes. These aren’t scary-looking or intimidating contraptions at all, but instead look modern and friendly. And using the device is more straightforward than others since MaleEdge’s penis extender uniquely has no removable rods; when it comes to adjusting tension strength, it locks in and remembers your tension setting between uses. However, the adjustment experience itself might make some users question its sturdiness. There were times when our testers felt that the device was at risk of breaking, though no breaks occurred.

Nonetheless, MaleEdge didn’t inspire as much confidence and trust in our testers as other penis extenders – and when you’re fastening a device to your penis, you want to be confident in it. It’s an appealing budget choice but, like many other budget purchases, might not stand the test of time as well as other slightly more expensive options. Indeed, one of the more common complaints among customers we’ve spoken to – even those who were pleased that MaleEdge works and recommend it – was the fact that the penis extender can break over time. We think you can do better in 2021, and thankfully our editor’s choice is a little less expensive, in addition to being sturdier.)

JES Extender

Pros

  • A long-standing reputation
  • Penis extenders with a bling factor
  • More affordable than PeniMaster

Cons

  • Unless you’re motivated by design or brand trust, you can find better value

Classified in Europe as a Class 1 Medical Device, JES Extender adheres to high standards in terms of its materials and construction. JES Extender is essentially the original traction-based penis extender and still has many adherents.

Both MaleEdge and JES Extender understand the positive impact of high design standards and fashion when it comes to personal gear; these devices just look impressive. If you or someone you love would like a penis extender in 24-karat gold, you won’t find that option from Quick Extender Pro but JES Extender has you covered. Not only could you get a gold penis extender, but the carrying cases themselves are not unattractive when you purchase a JES Extender.

Some men definitely want products that speak to them from a stylistic standpoint; we can recommend either JES Extender or Male Edge highly in that category. The company’s products have evolved admirably in its decades in this business, providing reliable performance and comfort in addition to the aforementioned style. While not as powerful as Quick Extender Pro or Phallosan Forte, JES Extender can provide 2800g of tension, allowing the traction method to enlarge the penis over the course of several months. JES Extender works.

But for our top pick, we were not seduced by good looks. Our recommendation of Quick Extender Pro instead of JES Extender boils down to an assessment of value; simply put, the Quick Extender Pro is just as safe and comfortable in our estimation, is capable of faster results through stronger tension, and sells at a lower price.

Are penis extenders safe?

When used as directed, penis extenders are very safe. You should follow the instructions on using your device to avoid potential bruising or discomfort. Listening to your body is important, too. Reputable penis extender companies explain a process of gradually ramping up tension strength and the number of hours you use the device. Following these programs is a necessary step to avoid any potential bruising.

Tingling and stretching sensations are normal when using a penis extender, but pain and discomfort aren’t normal or expected at all. If you encounter this, you should discontinue use immediately and contact the company. As long as you use the device as intended and aren’t overly aggressive in how quickly you increase tension, the devices are designed to cause no harm.

Conversely, any time you add a new substance to your routine – whether an oral supplement or a topical – you should talk to your doctor in case the supplement or medication might be contraindicated (inadvisable) for you due to medical reasons. This is true whether the substance is “natural” or not. We are unaware of any health supplement that positively affects the sexual performance of men without also posing a risk to a certain subset of men for underlying health reasons.

The other alternative, surgery, carries with it the risk of unintended side effects. Surgery is almost always a last resort in medicine because the risks of complications tend to increase as compared to non-surgical solutions. When there is a non-invasive, non-surgical method of achieving the same desired results, scientists and medical professionals almost always advise against surgery.

Cost of penis extenders vs surgery or pills

Surgery will be the costliest treatment path for penis enlargement. Surgical procedures to lengthen and increase the girth of the penis cost thousands of dollars – often ranging from around $6,000 to $20,000 depending on your location and the nature of the procedure. Often insurance will not cover any of the cost, though you would need to check with your insurer in advance.

Pills and creams might seem less expensive than penis extenders on the surface – a quick comparison of initial costs makes pills appear much more affordable. However, it’s very important to keep in mind that the pills require you to take them for as long as you want the intended effects. Instead of comparing a one-time supplement purchase to a one-time purchase of a penis extender, we need to consider the years-long cost of supplements. Over time, they become more expensive than a larger, one-time purchase of a device whose effects are permanent.

Convenience of penis extenders

There are different ways to consider convenience when it comes to penis enlargement. Taking a supplement each day would definitely be a lower-impact routine than wearing a penis extender device for several hours each day or recovering for weeks from surgery. On that level, nothing would be more convenient than pills.

On the other hand, it’s also important to consider that you’re taking this supplement for life (or for however long you want to enjoy the results – if the supplement is actually legitimate and produces results). With penis extenders, you have several months of frequent and long wearing, but afterward, your progress is permanent.

And also worth considering: the inconvenience of certain side effects from pills or surgery. Calling them “inconveniences” is actually an understatement in many cases. One type of surgery for penis enlargement carries the risk of shortening the penis and/or making it less stable during sex. The other main type of surgery involves implanting either your own tissue or a cadaver’s tissue into the penis, which can lead to infection or death of tissue.

Penis extenders can deliver proven results without a “forever” routine or side effects as long as you use them as directed and listen to your body. Thankfully, there are options for those who don’t see a path forward unless they can wear a penis extender underneath clothing discreetly or even wear them at night.
