What is Jes Extender?

Jes extender is a wearable penis traction device that helps you increase your penis length and girth naturally. It’s a non-intrusive penis enlargement method that over a million men have used in the last decade to get a bigger penis safely.

Jes Extender got its name from Dana Medic Apps Founder Jes Bech Muller. Muller got interested in the idea of a penis traction device in the early 1990s due to the growing demand for an effective and safe penis enlargement method.

Muller invested massively in the research and development process, and by 1995, Dana Medic introduced a revolutionary product that disrupted the PE industry. A low-cost yet effective clinically-tested and approved traction device that was found to increase penis length safely without going under the knife or stuffing your system with pills.

Nearly three decades later, Jes Extender has undergone various design improvements to increase its effectiveness and meet industry standards. It is FDA-approved, European CE-certified and it is sold directly by the manufacturer. No middlemen. No fake penis extenders.

Apart from a bigger penis, Jes Extender also guarantees you the following benefits:

  • Better blood circulation in penis tissues
  • Rock-hard erections
  • Higher sperm volume
  • Corrects penis curvature

How Does Jes Extender Work?

Jes Extender works through a scientific process known as “cytokinesis”, which means “cell division”. The device applies constant tension to the penis tissues, causing microscopic tears within.

The constant pressure causes the penis tissues to multiply and fill the tears. As the tear continues, the tissues built up, giving you an extended and thicker penis size. As long as you wear the device and adjust the traction over the recommended period (usually 4 to 6 months), the penis will continue increasing in length and girth.

While this process may sound “unusual” to most people, traction and stretching body parts has been used for over a century. From lip elongation in Ethiopia, earlobe stretching in Africa, to neck elongation in South East Asia, traction is an age-old tradition.

From a medical perspective, plastic and reconstructive surgeons have used traction to help patients grow their skin, muscles, bones, and tendons. The body works under mechanical stress to trigger cell division in body tissues to encourage the growth of body parts. 

Penis traction also works the same way as bodybuilding. As muscle builders lift weights, the muscle tissues are subjected to mechanical stress that causes the tissues to tear, multiply, and rebuild, as the muscles expand. Muscle building is not a one-day work. It takes patience, discipline, and consistency, the same as penis enlargement.

How to Use Jes Extender (Best Routine)

When you order Jes Extender, the company ships the product (at zero fees) within a few days, depending on where you live. The device comes pre-assembled, and it makes the training program seamless. The key components include:

  • A ring that fits at the base of the penis
  • A rubber strap for comfort
  • Two adjustable spring-loaded bars that are connected to the base ring.
  • A front piece to support the head of the penis.
  • Extra elongation bars (included in some of the Jes Extender options.

Once you have confirmed that everything is in order, and the appropriate parts are present, get ready for the exercise. Start by doing simple warm-up exercises like jelqing to get your penis ready.

Check out these simple steps on how to use Jes Extender the Right Way:

Step 1: Place flaccid penis through the base ring

The first step is to place your flaccid penis through the base ring so that it lies against the pubic bone. The penis should be within the two elongation bars. The ring and the elongation bars should be slightly longer than the flaccid penis so that there is a gentle stretch. Once you get the right traction, fasten the rods.

Step 2: Fix the front piece onto the penis head

The next step is to attach the front piece to the head of the penis. Position the front piece on the penis head, insert the elongation rods into the two side slots, and fasten the rubber strap around the penis head. The device will produce a click sound once the device is appropriately fastened and secured.

Step 3: Apply tension

Once you’ve fastened the device properly, twist the elongation bar screws inwards (towards the penis) to adjust the traction. The amount of tension should be moderate (not too tight or too loose) so that you can feel a gentle stretch of the penis muscles.

To get significant results with Jes Extender, you must wear the device for at least 4 to 6 hours every day for at least 4 to 6 months. Jes Extender introduced a slow start-up schedule for first-time users to help them get comfortable when wearing the device for the first time.

Most often, first-time users may experience skin issues and pain if the device is worn incorrectly. Jes extender's schedule allows users to adopt a slow start to allow the body to get used to the exercise, before increasing the number of hours per day as the body gets used to the regime.

If you experience pain anytime during the PE exercise, you should pause wearing the device for some time to allow your body time to heal and recover. Also, wearing the device may be uncomfortable with tight clothing. Make sure you wear loose pants that give your Johnson space to wiggle around.

Results to Expect with Jes Extender

There are dozens of mixed reviews on Jes Extender. But one thing is for sure; Jes Extender gives your REAL results, but at a slow pace. It takes several weeks to months to notice a significant increase in penis size or girth.

Jes Extender works through a process known as cytokinesis, which is the sub-division of cells. This is not a one-day process, and it takes some time to produce visible results.

Generally, if you wear the device consistently for at least 4 months, you should expect to see 0.7 to 2 inches growth in penis length and about 0.1 to 0.3 increase in penis girth. After 6 months of continuous use, users have reported gaining up to 2.9 inches in penile length and 0.5 inches in penile girth.

And not just that. If you have a curvature in the penis, also known as Peyronies disease, Jes extender users have reported a 50% reduction in the plague within 4 to 6 months. This curvature correction is enough to straighten the penis to a near-perfect state.

Jes Extender’s internal data shows that users averaged 0.05 inches per week in penis length increase. This data is obtained from customers who self-report their progress in the online diary, and the Jes Extender before and after photos taken by customers.

Are Jes Extender Results Permanent?

Jes extender uses a mechanism known as Cytokinesis to deliver results. This process triggers the sub-division of cells in the penis tissues, and it is an irreversible process. This means that any results gained using this device is permanent and irreversible.

But there is a catch;

To get the required results, Jes extender and PE doctors recommend using the device for at least 6 months. This is because your body, specifically your penis, needs enough time to fully adapt to the new change.

Although most clinical trials show that penis extenders are only effective for the first 6 months, no studies exist on the penis extender’s effectiveness beyond the 6 months. Some users in men health forums have reported using the device beyond the 6 months and still seeing results.

Like bodybuilders need exercises to keep their muscles active, your elongated penis also needs some form of exercise to keep it active and longer. Doing jelqing exercises, and getting intimate with your partner can help you retain the results, and still enjoy intimacy better than before.

MypenisandI wrote:

I logged 500 hours + with Jes Extender, and my penis length increased from 7 to 9 cm. There was a mild improvement in the girth, but not as much as the penis length. I am still using the device 9 months later

Englishpatient wrote:

My flaccid penis increased by an inch by the fourth month of use, and I even got a mushroom head. And oh my, the cum load is on another level. Weird but my girlfriend is in love with my new Johnny. This device is a must-have, but its tiring to wear the device every day. If you hate commitments, please, just stick to your short penis.”

CoinGuy wrote:

“My review is mixed. My penis now measures 6.75 when erect after 3 months of use, up from my previous size of 6.25. Way better than before, and my wife of now demands a good whacky every morning. And the best part is that I wear it in the office, and I go on with my day as usual. Nobody will notice the bulge unless it’s your naughty side chick. Haha.”

It is my third week wearing this device and my penis is all bruised up. I can't even go for more than 30 seconds. Utterly Disappointed. Going back to manual exercises

Supreme Leader wrote:

I purchased Jes Extender 3 months ago, and everything was smooth. The package was delivered the next day, and it was unmarked. Nice job guys. The only challenge I am having is that I have only increased to 6.7 x 5.5 up from 6.5 x 5.5. A growth of 0.2 is just not enough after all the effort I have put. I think I hoped too much, or this device is not for me. I will continue with the training until 6 months as recommended as see how it turns out. Will share my results later

Scientific Studies Backing Jes Extender Results

A 2008 study conducted by Paulo Gontero and others aimed to test the efficacy of a penis extender device in treating "short penis". The study analyzed results from a sample of 15 men, who wore the device for at least 4 hours per day for 6 months. After 6 months, the sample population reported a significant gain in penis length of 2.3 cm and 1.7 cm for the flaccid and erect penis respectively. The study also reported a significant improvement in erectile function. The researchers concluded that penis extenders are a minimally invasive treatment that can effectively elongate the penis length in men seeking treatment for a short penis.

Another 2015 research published on the British Journal of Urology International found penis traction devices to be an effective mechanism of increasing penis length naturally. In a sample of 23 men, the study found that the average flaccid penis length increased from 8.8 +/- 1.2 cm to 10.1 +/- 1.2 cm and 10.5 +/- 1.2 cm in the first and second month of study. This study confirmed penis traction devices to be the only evidence-based method of increasing the glans penis length and girth safely and naturally.

Researchers have also conducted studies to determine the effectiveness of penis extenders in correcting penis curvature in men with the Peyronies disease. An internal study by Dana Medic sampled 26 males with Peyronies disease. These males were required to wear a penis traction device for at least 6 months to test its effectiveness in correcting the penis curvature. Out of the 26 males, 7 males reported that the device corrected the plague deposits completely, while the other 18 males reported a reduction in the size and consistency of the plaque deposits.
