Jes Extender

Jes Extender Review: Results & Side Effects [April 2020]

My Jes Extender review is the only one you’ll need to read to know if this penis extender is right for you. I’ll tell you about effectiveness, scientific research, how to use it, and more. 

For me, the enhancement device was a game-changer. Years of resentment over my smaller-than-average penis had started to build up. No matter what we’d like to believe, women do have an affinity for well-endowed men.1

Everything from my self-confidence to my abilities between the sheets declined until I hardly knew myself. I had given up on looking forward to sex without anxiety about being judged.

The Jes Extender helped me add on the inches until I felt like myself again. By transforming my manhood from puny to proud, my life changed for the better.

Jes Extender Background

This penis extender is all about variety. Buyers can choose from five kits, ranging from just under $200 to an even $1,000. Prices are current as of when I wrote my review:

  • Dollar coinsJes Extender Light ($199.99).
  • Jes Extender Original ($229.99).
  • Jes Extender Titanium ($249.99).
  • Jes Extender Gold ($349.99).
  • Jes Extender Platinum ($1,000).

All of the packages contain the Jes Extender device. If you’re wondering why some of these units have exorbitant costs, allow me to clarify. 

The metal-themed titles (e.g., gold and platinum) aren’t random: they refer to what the extender is coated with.

The Jes Extender is manufactured by the Danish organization DanaMedic ApS. Named after creator Jes Bech Müller, it has the distinction of being the original penis extender. 

Tattoo machineThis old-school model has been in production since 1995. It was designed by plastic surgeon Dr. Jorn Ege Siana. 

The traction instrument used to be prescribed to patients following penis enlargement surgery. Doctors quickly realized that the size-boosting effects could work for any man. 

DanaMedic ApS is responsible for managing the SizeGenetics brand, another popular penis extender. They have 20 years of experience in the field of male enhancement, so you can rest assured they know what they’re doing. 

Who Is This Penis Extender For?

Person sweatingAre you disappointed with the size and shape of the penis you were born with? Perhaps you developed Peyronie’s, and you’re tired of living with it?

If you answered yes to either of my questions, the Jes Extender could work for you. It’s a simple, scalpel-free method of enlargement you can perform from home. 

Traction therapy has demonstrated success at straightening out penile curvature.2 The same applies to naturally-occurring curves, including Chordee.

Now, those of you who suffer from the condition will already know the treatment options. If you undergo surgery, there are no guarantees: you might need a second procedure.3

Why not try a non-invasive method first? The Jes Extender could alleviate or potentially get rid of your unwanted bend entirely

The most attractive feature is that a straight penis isn’t a prerequisite to growth. If you do have a curve, increased length and girth will happen with time regardless.

Who Can Use Jes Extender?

Group of peopleThe Jes Extender is appropriate for almost any user craving a change down-below. As long as your penis is over 1.6 inches flaccid, you’re good to go. 

This penis extender doesn’t require your doctor to sign off on it. If you do have a condition affecting your manhood (e.g., a urinary tract issue), I recommend checking with your doctor.

We’re talking about your most sensitive anatomical part; there’s no harm in clearing the Jes Extender with a professional first.

Is the Jes Extender Effective?

For many of you, this is the portion of my Jes Extender review where you make a decision. There’s no reason to invest in a penis extender that won’t upgrade your penis the way you want.

Granted, I’m a satisfied buyer—but you’ll want more of a guarantee than that. I’ll present you with customer feedback and the science behind devices like the Jes Extender.

User Success Rate 

Numbers 1234 with magnifying glassLet’s talk numbers. The Jes Extender has been in production since 1995: the manufacturer boasts over half a million happy buyers across the globe.

The manufacturer is willing to bet you the cost of your package of choice. If you diligently document your usage of the Jes Extender for 1,000 hours and see no results, they’ll refund you 100 percent.

There’s also a graph on the website of user progress. Staff diligently collected photos and reviews from men who have used the device as directed.

The average man should benefit from a 28 percent length increase, and a 19 percent girth increase within four to six months

Jes extender Scientific Research 

Lip with scalpelDon’t forget that the person responsible for developing the Jes Extender is a plastic surgeon. This product has been clinically tested to ensure it’s both safe and effective. 

There’s a valid certification behind my claim. This penis extender has been assessed under the European Medical Device Directive. It falls under the CE umbrella, meaning it’s classified as a Class 1 medical device in Europe.

Penile traction devices have plenty of evidence to support their capabilities. In one study, participants benefited from additional length as well as a thicker glans.4

These instruments are also compatible with Peyronie’s treatments with undesirable side effects, such as length loss. An investigation into the issue showed that men taking injections or who had undergone surgery managed to preserve penis length.5

Curved arrowYou can reduce how pronounced your curvature is if you’re consistent. A trial monitoring Peyronie’s patients for six months showed that curves decreased while length increased. 

All the men wore their penis extenders for a minimum of five hours per day. The size improvement was permanent: another six months later, measurements were the same.6

Penis extenders are also one of the few non-surgical methods with proven results.

The inches you can gain with something like the Jes Extender are comparable to what you can get after enlargement surgery.7


  • Reputable manufacturer.
  • One of the oldest penis extenders on the market.
  • Full money-back guarantee.
  • Versatile styles (e.g., platinum, gold, etc).
  • Hypoallergenic materials.
  • Flexible routines for comfortable enhancement. 


  • Precious-metal-coated extenders may seem frivolous to some users.

What Does the Jes Extender Promise?

ResumeThis section of my Jes Extender review details what this penis extender claims to be able to do for you. I’ll sum up why each one is important, and what problem it could fix.

1) Comprehensive Penis Enlargement 

Small penis syndrome is a legitimate condition. Shame over your dimensions can lead to erectile dysfunction, or worsen existing difficulties getting and staying hard.8

The Jes Extender will take your measurements up while keeping you proportional. You won’t only grow longer with no change in girth: you’ll be bigger overall.

Length is worth nothing if you’re not expanding in width too. You don’t want a long, skinny noodle to replace your short member.

2) Straighten Curves 

Whatever the cause of your curvature, a bent penis is unpleasant to live with. If you’re playing the field, you have to worry about your partner’s reaction every time you have sex.

Side bending postureThe bend can make erections painful to the point that you fear being aroused. Depending on how severe it is, sex could be uncomfortable for both you and the other person too. 

Correcting it can make a dramatic difference in your quality of life.9 The Jes Extender doesn’t come with any nasty side effects that other treatments (such as surgery) do.

3) Enhance Stamina and Erection Quality

We know that blood flow is the metaphorical engine behind our erections.10 A penis is a prime example of hydraulic-powered equipment. 

Better blood flow equals stronger erections. Since penis extenders promote blood circulation, you could see your hard-ons and stamina make a comeback.

What to Expect: Timeline of Results

You didn’t think I’d write a Jes Extender review without a timeline, did you? 

Man thinkingIt’s vital to know what to anticipate when using a penis extender, and when. That applies to both skeptical and overly optimistic users.

If you have low expectations, it won’t hurt to get excited about the process. Don’t go into the experience, believing nothing will happen.

At the same time, the Jes Extender isn’t magic. You won’t see an inch of growth a week, or find yourself astoundingly well-endowed after a month or two.

text saying realistic expectations

We’re all different, meaning our enhancement journeys won’t be exactly alike. Adding to that, not every user will follow the same routine. I’ve given you an estimate of the timeline an average user will follow.

My final piece of advice to you is to commit to the penis extender. Wear it as often as you can at a traction level that’s tolerable for you. These gadgets are non-invasive, but the catch is that they need dedication on your behalf. 

Week One To Two

Number 1The first week is like the penis extender equivalent of your freshman year. You’re getting used to the Jes Extender, building up to wearing it for at least an hour a day. 

Perhaps you’re still switching between the comfort strap and the noose. Most of you won’t see anything at all in the way of changes to your manhood. 

At week two, you’ve hit your stride. You’re wearing the Jes Extender daily for at least an hour per day. Some of you may be comfortable wearing it longer than that.

By the end of the second week, you may usher in your first millimeter or two of growth. You’ll also see that your erections are a little more rigid than when you began.

Week Three To Four

All of you will see change by the third week, even if only by several millimeters total. Remember, millimeters eventually turn into inches.

Glass full of wineYour manhood looks and feels slightly fuller than it used to. Improved blood circulation translates into erections that are definitively stiffer and harder

By week four, men who began with curved penises will notice erections may not be as painful. Your manhood has begun to stand a little straighter than it was. 

By now, it’s clear that your length has improved. Your ruler will show another millimeter or so extra, and your penis is looking thicker overall. Believe me, it is going to be very motivating. 

Week Five To Six

By this stage, you’re not the only one seeing that a transformation is taking place. If you have a regular sexual partner or significant other, they’ll remark on your size gains.

The self-esteem boost combined with regular stimulation means your erections are steely strong. Your performance in bed has undergone an upgrade too. 

RulerBy week sex, a couple of more millimeters has your penis looking and feeling great. It’s thicker and longer, whether flaccid or erect. You don’t need to check your ruler to establish the difference.

If you have a curve, it will begin to look better than it did when you started your journey. You may have lost as many as several degrees of curvature.

Week Seven To Eight

The Jes Extender is your constant companion as you close towards the end of the second month. If you’ve worked your way up to higher traction, you have nowhere to go but up.

Your penis is impressively engorged when hard. The days of weak or failing erections are behind you. You’re visibly bigger than you were, whether your manhood is soft or ready for action.

By week eight, a few more millimeters has you hitting a total of up to six or more millimeters of growth. The majority of users will be halfway to the 0.5-inch mark

Food cover shiningYour partner is praising your choice to persevere with the Jes Extender. You’re no longer uncomfortable exposing yourself before sex: your penis is looking good.

Week Nine To Ten

By week nine, men with curved penises will notice that some straightening has taken place. Your curve will be less pronounced. In turn, erections should feel less painful (if that was an issue before).

All users will find that their penises are close to 10 percent bigger than the starting size. Your member feels heavier and fuller, and your erections are almost always reliable and strong.

By now, you’re growing at a steady pace. If you’ve upped your traction level, you may see up to two millimeters of growth happening per week

Week Eleven To Thirteen

Measuring tapeYou’re thrillingly close to 0.5 inches of additional length by week eleven. Your new and improved measurements have turned you into a sexual athlete. 

By week twelve, the change in your penis is dramatically apparent. You won’t need your ruler to tell you that you’re nowhere near the same size as when you began. 

By three months, the majority of users will celebrate up to 0.5 inches of permanent growth.

Curvature is far less obvious than it used to be. When it comes to erections and sexual prowess, you have nothing to complain about. 

How to Use Jes Extender?

You don’t need to tell me that penis extenders can be tricky to assemble. Thankfully, the Jes Extender doesn’t fall into this category. Learn how you’ll be setting it up and removing it with my step-by-step instructions.

NB! Jes Extender has detailed instructions (brochure + video) included, so you can skip this section and learn about the usage once you have ordered the product.

  1. Before you start attaching parts, check the adjustment screw handle. There should be 1 millimeter of space on both sides.
  2. The penis extender should be slightly longer than your penis. Add as many elongation bars as necessary to make this happen.
  3. Fasten the plastic front piece. Insert it into the bars until you hear a click.
  4. Choose between either the silicone noose or the comfort strap. Secure your fastener of choice into the slots of the front piece. If you want, you can add gauze or a protection pad to shield your skin from the strap or noose.
  5. Insert your penis into the base of the Jes Extender. Slip through the strap (or noose) and tighten as needed. Let the springs click home by pushing the front piece.
  6. Release the front piece by letting the springs expand. You should feel a pull, but there shouldn’t be any pain. Use the hand screws to adjust accordingly.
  7. Weight scaleEach mark corresponds to a traction level. The first mark is 900 grams, the second 1,200 grams, and the third is 1,500 grams.
  8. Once you’re done with your daily session, loosen the strap or noose. Take the device off. 

Frequency of Use 

Men who are novices to the world of penis extenders are encouraged to start gently. Jes Extender suggests sticking to this routine:

  • Week 1: One hour per day at 900 grams of traction.
  • Week 2: Two hours per day at 900 grams of traction.
  • Week 3: Three hours per day at 900 grams of traction.
  • Week 4: Two hours per day at 1,200 grams of traction.
  • Week 5: Three hours per day at 1,200 grams of traction
  • Week 6: Four hours per day at 1,200 grams of traction.

WatchKeep adding hours (and traction) at a pace that suits you. If you find this routine is too slow or too quick for you, adapt it to fit your needs. Your final goal is 12 hours of daily wear at a traction of 1,200 grams.

Choosing Your Traction Level

What if you’re already accustomed to penis extenders? What if you’ve never used one before, and you’re afraid to injure yourself? 

This section of my Jes Extender review answers all your questions about traction. The strength of the pull is nearly as essential as the duration you wear the device for.

For Beginners

The lowest traction level you can achieve with the Jes Extender is 600 grams. If the starter pull of 900 grams feels excessive on your penis, go down by 300 grams.

Best Traction Level

Pulling handIdeally, you want to acclimatize to 1,200 grams of traction. The more powerful the pull, the more rapidly your penis will grow. 

I don’t want to encourage you to try traction you aren’t ready for. All that will happen is you’ll feel discomfort and want to stop using it. You won’t suddenly get bigger.

What About Slippage?

If you notice that you have to keep readjusting your Jes Extender, don’t be aggravated. Instead, see if you’ve assembled the penis extender correctly.

Are the straps too loose? Did you neglect to click the front piece back into place? If you’re setting yourself up in a rush, you might have forgotten something.

You can also experiment by interchanging the noose and comfort strap. Based off the shape of your penis and your personal comfort levels, one might work for you better than the other.

Jes Extender Side Effects and Complaints 

Two hands with bubblesAs I told you, my Jes Extender review is all-inclusive. That means talking about the negatives as well as the positives.

I’ll start with possible physical symptoms you might notice on your manhood. Before I list them, I have to emphasize that these aren’t typical penis extender effects:

  • Blueish discoloration.
  • Soreness.
  • Pain.
  • Redness or irritation.
  • Numbness.

If you’re seeing any of the unpleasant symptoms above, there’s a good chance that human error is the culprit. You went too far with your Jes Extender (e.g., the traction is too high or you wore it for too long).

Men who followed instructions to the letter will have to consult a physician. There might be something going on with your penis that you aren’t aware of.

Number zeroAn equally severe effect—or rather, lack of one—is zero results. No inches gained, no thickening of the penis, same old inadequate erections.

Be honest with yourself before you blame the penis extender. There’s a reason Jes Extender requests 1,000 hours of use before you demand your money back.

Are you using it regularly, or less than once a week? Is the device slipping to and fro all day, signaling it’s far too loose?

Jes Extender Review Final Verdict 

The Jes Extender heralded a new beginning for me. I didn’t realize how much my dissatisfaction over my penis size was affecting the rest of my life. I don’t only mean sexually: I constantly felt low about myself, inadequate.

I’m proud of my manhood now, and the commitment it took me to enhance my measurements. 

I hope the Jes Extender can do the same for you. My final verdict is wholly in favor of this penis extender. Yes, the precious metal kits may be considered flashy for some, but you can stick with the Light or Original packages. 

This penis extender has an excellent value for what you pay for. Even if you buy the Platinum Jes Extender, you get a lifetime warranty and certification that it’s genuine platinum.
