For those who wish to know more about penis extenders, the next section is for you.

What are Penis Extenders

Penis extenders are taking a surged into the mainstream discussion. It is experiencing a growing popularity among men like you who are looking for a way to increase the size of their penis.

Initially, the only solution to a bigger penis is by going under the knife. The process is dangerous and its efficiency is not reliable. Due to this, a new solution is discovered, which is safer, more reliable and affordable.

Extenders are designed to stretch your manhood. These devices are also called penis traction device as it works following the concept of the traction principle. So, how does it work? Check it out in the next section!

How Does Penis Stretchers Work? 

Based on the traction principle, the skin tissues and muscle experience microscopic tears when stretched or stressed. The spaces between the cells are opened but the body triggers the natural repair process where the cells adjacent to the affected site divide and fill in the space. In short, the cells bridge the gap.

With each cell division called mitosis or cytokinesis, the area is healed due to the addition of new cells and new tissues. The process can be repeated until the desired size is achieved. This works with skin grafts, body building exercises and penis enlargement.

For instance, the skin heals by producing new skin cell. The muscle works in the same way too. When exercise tears your muscle, your body repairs it by producing more muscles, which results in a larger muscle. This is why those who keep on lifting weight develop more muscles. Penis enlargement stretchers operate in the same way too, which explains why it is effective.

How Effective are Penis Extenders?

Are you ready to learn the potential gains using this method? On average, nonsurgical male enhancers showed 0.75 inches gain in length.

However, you should slow down and consider the wearing time. The longer and the more constant you wear this male enlargement device, the more results you will see.

The particular gains in length and girth are subjective but it is guaranteed. Three different studies attested of this. You can find it below:

#1 Danish Study in 1998

The study conducted by a Danish physician Dr. Jorn Ege Siana in 1998 aimed to examine the efficiency of penile traction. The said study was published in the Journal of Sexual Medicine.

The study lasted for 24 weeks and involved 18 men between 20 to 40 years old. The participants used SizeGenetics.

The results showed that there was an average increase of 13 percent in the first 8 weeks and 2.8 cm or 1.1 inches in erect length after 16 weeks. Overall, the average erect length improvement weekly is 1.9 mm.

At the end of the trial, the biggest erect length reported is 40%. Meanwhile, the average gain in girth is 0.75 inches.

Overall, a 6.4-inch penis could increase up to 8.26 inches in length. However, the more challenging part is that the participants wore the device for 12 hours a day.

#2 Italian Study in 2008

After a decade, another study conducted by San Giovanni Battista Hospital learned that moderate daily usage has another result.

The participants in this study only wear the device in 4 to 6 hours for over 6 months and the results were still astonishing.

The participants’ average flaccid length has increased by 0.9 inches. The average erect length also increases by 0.66 inches. Overall, it shows 32% increase in flaccid penile length and 18% increase in stretched penile length.

#3 Canadian Study in 2009

This study is published in the Canadian Journal of Phalloplasty. It is one of the few works that prove traction devices can help one’s girth size too.

The participants in this clinical study wore the device for 6 to 8 hours daily for 5 months. At the end of the study, the researchers learned that:

There was an increase of 32% in penile length for both flaccid and erect state. Surprisingly, there was also an increase of 36% in penis girth. The participants also reported 36% increase in erection.

Overall, the Canadian study reported that penis extender can increase penis size and girth. It also helps one achieve stronger erections.

The researchers conclude that penile traction is effective and minimally invasive treatment option for those who wish to enlarge their member without getting under the knife.
Check out the table below to see the data of length gain versus wearing time. You will observe that this produce has a high rate of success.

Do You Need This Male Enhancement Device?

Most men are anxious about the size of their member. In fact, most feel that they have a small penis when their size is just the average. However, whether you have a small or average dick, one thing is certain you still want to grow your member unless it is not as large or as thick as David Beckham’s or Orland Bloom’s.

Now, if you are unsure then you can measure your dong to see if you still need to enlarge it. Check out the photo below to see where your penis belongs.


According to a 2015 U.S. study, women preferred a 6.3-inch penis with a circumference of 4.8 inches for their long-term sex partners. However, they want a bigger dick, 6.4-inch with a circumference of 5 for casual sex encounter.

The said study involved 76 women. The researchers used 3D printed model scale figures for references.

Now, is your penis size 6 inches or longer? Based on the photo, 6-inch is an average size. A 4-inch penis is mini, a 5-inch penis is small. So, decide for yourself if you need to get a penis extender.

Why You Need A Penis Stretcher….

A male enlargement device offers more than extending the length of your member. If you have a big penis, you will enjoy lots of things that your small member is holding you back due to your insecurities. These include the following:

Boosts your sex appeal

Does the size of your member affect your sex appeal? Yes, it does.

According to a 2013 study, women judge men’s attractiveness based on the size their penis size. For instance, well-endowed shorter men are ranked more attractive than men of the same height who are not well-endowed.

Improve your self-perception

I know that men’s self-esteem changes according to the size of their member. The bigger we have down there, the better.

If you don’t want to keep quite while your friends talk about the size of their dick, join them. However, you should grow yours before you compete with theirs. Thus, this device will be of great help to you.

Peyronie’s Disease

A number of studies agree that penile curvature or Peyronie’s Disease can be helped by penis extenders. One man of out 10 with PD suffered from penile deformity.

Professionals believe that genital stretchers can help cure the curvature caused by PD. So if you are suffering from the same condition, this device will be of help to you.

Grow your penis

The number one reason, penis extenders are popular is its ability to increase the length of your manhood. If you fall below the average, you definitely need this device.

According to the photo above, the average length is 6 inches. So, if your size is smaller and you don’t want to live with it all your life, this is your chance to improve it.

Aside from improving the length of your penis, this tool can also help you achieve a thicker dick. Perhaps you are asking this now, “can penis extenders increase girth size too?” You will not be disappointed because it does.

Girth refers to the thickness or circumference of one’s penis. Aside from the length of your penis, this is another factor that contributes to a woman’s pleasure. Some men have impressive length already and just wish to improve their girth. In this case, this device can be of help too.

X4 Labs, in particular, promises a significant increase in length and girth. The company even offers a money back guarantee to ensure consumers that they deliver what they promise.

However, despite this, you should take note that penis stretchers are more popular and effective in improving your member’s length. Penis vacuum pumps, on the other hand, are more effective for girth.
