The Jes Extender is the oldest among modern penile extenders. It got its name from Jes Bech Mueller, the founder and CEO of Denmark-based manufacturer DanaMedic ApS, the manufacturer of Jes Extender. In 1994, Mueller collaborated with Danish surgeon Jorn Ege Siana to develop this device.
DanaMedic also makes other penile extenders. There is the SizeGenetics (read our SizeGenetics review here), which looks the same as Jes Extender, and the MaleEdge, a second-generation penile extender introduced in 2008.
Jes Extender has the European CE mark as a Class 1 medical-grade device, making it safe for home use. In Australia, it’s the only penile enlargement device approved by the TGA (Therapeutic Goods Administration). DanaMedic stated that Jes has a pending registration with the US FDA (Food and Drug Administration).
According to DanaMedic, the Jes Extender offer the following benefits:

I have logged over 500 hours with the Extender and have gone from 7x5.5 to 9x5.5 and am very pleased with the results. I have bought additional rods for future growth. The last girl I slept with couldn't believe my size.
I recently bought the Jes Extender, hoping I could add half an inch to my 6”x5” penis. Well, I guess I hoped too much.
As recommended, I started slow, only one hour on the first day. I steadily increased the number of hours until the third day. The tension I used never exceeded 900 grams.
On the fourth day, everything seems normal. But at the back of my mind, I was thinking that I’m not getting the usual boner when I wake up. For the rest of that day, it was difficult for me to maintain my erection, plus it doesn’t happen spontaneously. I reckon that this is due to overworking my penis and the constant worrying when the penis is not in its normal mode.
My flaccid penis is now over an inch longer, and its head is bigger as well. The one complaint that I have is that it is so hard to wear the extender day-in and day-out. Jes Extender undoubtedly works, but you must have the commitment to make it effective.
I disapprove this. I initially thought gentle stretching for long periods of time will do wonders for my penis. Unfortunately, I had no success so I am back to doing manual exercises. Right now, I am considering doing pumps.
This is my first review. I have some good and some bad things to say about them. First, they are effective. I have an erection length of 6.25” and, after 3 months, it is now at 6.75”. The downside though is that you need to wear this thing a lot.
I disagree though that it will look obvious that you’re wearing this extender. As long as you wear loose pants, no one will notice. Unless someone is looking at your crotch.
The Jes Extender promote a painless, non-surgical way of penis enlargement through the process of traction.
Simply put, traction is stretching. By subjecting a flaccid penis to a steady, gentle dose of stretching, Jes Extender takes advantage of the body tissues’ ability to grow under stress. Setting the tension between 900 to 1,500 grams force will stretch your penis beyond its current length.
Over time, the cells will divide and multiply as a response to continuous stress. This natural process is called cytokinesis. As a result, cells multiply and the tissue grows in size, which is then manifested as an increase in penis size. While gains happen mostly in length, there is also an increase in girth as well.
Traction is not a new process, and it’s the same mechanism the body uses for broken bones and grafted skins.
Jes Extender is made up of four units:
After assembling the Jes Extender, here are the steps to use it:
For full instructions, check the included manual.
For starters, here is a sample routine:
|Period||Recommended Traction||Number of Hours Daily|
|Week 1 to 3||900 grams||1 to 4|
|Week 4 to 6||1200 grams||4 to 6|
|Week 6 onwards||1500 grams||6 to 12|
The above routine is for guidance only. Once you hit a certain level of comfort, you can change the way you use the Jes Extender. You can use it 4 to 6 times a week and don’t exceed 12 hours of usage per day.
Remember that, like any penile exercises and other penile enlargement tools, it’s best to start slow until you get accustomed to using the extender. Your extension activity must be seen as a marathon, not as a sprint.
Once you get the hang of it, you can now wear Jes as you like, not only during your free time. You can wear it with loose clothing, without anyone noticing you are actually wearing it. You can wear it to work, as long as your job is not physically demanding. You can even wear it while sleeping, as long as you don’t turn a lot or as long as you remain lying on your back.

Four studies have been cited by DanaMedic on its website, showing the effect of penile extenders on penis size and curvature. However, it is not explicitly stated that Jas Extender was the actual extender used in these studies.
As one of the original penis enlargers on the market, there’s a reason why Jes Extender stayed relevant even with the arrival of supplements and other penile enhancement products. The Jes Extender can lead to size gains with zero side effects, as long as the product is used properly. The only issue is that there is initial discomfort for first-time users.
If you’re the type of person that will quit from frustration after using the extender for a week, then this device is not for you. Results vary between users, but generally, three months is what you’ll need to really notice some size increase. Extend your usage to six months to attain the full potential of this device. We have heard of users extending the usage beyond six months; surprisingly, their penises still register some growth.
For patients who underwent a penile surgery, they also can benefit from the Jes Extender. Penis retraction is common after such procedure so an extender can help regain original penis size, even gain some more. It’s strongly recommended though to recover first before attempting to use the Jes Extender.
As we mentioned in the “How to Use” section, it is important to start slow. Once you become comfortable with the device, you can now use it for 12 hours, for at least six months. Consistency is the key, so you must use the device regularly.
In the end, the good thing with the Jes Extender is that you can choose when to use it, apply the precise traction that meets your needs, and stop once you already attained your goal.
As customer reviews get older with time, they scroll all the way down to this section.
In my case, the Jes Extender did work. After six months, I gained 0.5 inch in erect length. I have been taking some medications lately so my erection and libido is a bit low. Otherwise, there could be an extra length in there. But I have no worries, I will still continue to use it.
For me, this is a nice gain already. Just don’t expect two inches or more after 6 months of wearing it.
I read about pills, creams, and patches, and they all sound crap to me. No, I have not used any of them, but I still think they’re just a waste of money. I also thought that jelqing and penile exercises are also crap, but I discovered they do work.
Then, I stumbled upon extenders and how to use them. Put your penis under traction, then it grows bigger. If you look what happens to guys who have those circular things in their earlobes, it is the same case with extenders. Just put it on, that’s it. It’s good when you just free time at home, in front of the TV or computer. Once you’re used to wearing it, then you're all set.
The Jes Extender that goes with the noose-strap combo is very uncomfortable. But don’t let that discourage you from trying extenders. Check VacExtender Mod or the VLC tugger (if you're uncircumcised like me) as they go along with extenders. I have these two so I’m experienced in both.
I stopped getting length gains due to how inconsistently I am with using the Jes Extender. But my wife says I got a thicker penis now. I currently have a 5.75-inch erect girth, and I was about to hit 6 inches in a few weeks if I continued using the extender.
With extenders, where most men fail is in the commitment part. Hey, it’s not their fault though, as not everyone has the time to use them until they reached their goal. I wore mine to work, church, concerts, even on dates. I can’t think of any place I went to that I don’t have my extender with me.
After 6 months, I gained one inch in erect length and one inch in erect girth. I used to be 6”x5”, now I am 7”x6”. I previously do jelqing and pumps, and never have I gained these much increase. I guess extenders are not a gimmick after all.
I have not checked any erect gains, but my flaccid penis is now 5 inches as opposed to just 4.5 inches when I started four months ago. But I’m more about getting erect gains. I will try the 1500 grams and see if that would help.
During the first six months, I wore the Jes Extender for 6 to 7 days per week, 8 to 12 hours per day. I always have it whenever possible. After six months, I reduced the frequency to just 5 days per week. Nowadays, I use less frequently. I had a slightly curved penis, and the extender does make it straight.
I personally have a Jes Extender, and I’m quite satisfied with it. If you are thinking of buying one, be patient as the progress is gradual. Good luck.
