Penis Extender Devices: What Are They and How Do They Work

Penis extenders, penis traction devices and penis stretchers – no matter what name you call it – are amazing drug-free, non-operation methods that can help men have a longer penis.
While the results of a longer penis take time – months even – they are permanent and have helped thousands of men around the world to attain the larger penis they want. And, along with this larger penis size, have a higher confidence in themselves.

The Science Behind Penis Enlargement Devices

A man who is looking to purchase male enhancement cream, gel or oil needs to do a lot of research to make sure that he gets the right cream that really works and not the one that will simply bilk him out of his money. To help you choose the best product for you, I have done all of that research for you. I have conducted a thorough research on the most effective and most reliable products available on the market today (some of them I tried myself and even used for a while).

A penis enlargement device will expose your penis to a gentle but constant traction. This causes the tissues to gradually stretch and expand. Don’t worry! It’s 100% safe, and most folks don’t even notice the treatment is working until they actually measure for their results.

Within days, you’ll start to develop new penis tissue, which will cause it to grow thicker and longer. The more the penis extender device is used, the bigger your penis will grow.  Yes, it’s that simple!

On average, men who use an extender for six months see a 28% increase in their penis length and a 19% increase in the girth.  This means:

  • If your penis is seven inches long now, you can expect to see an additional 2 inches (9 inches total).
  • If your penis is six inches long now, you can expect to see an additional 1.7 inches (7.7 inches total).

How Do Penis Traction Devices Work?

These devices work through a very simple process that constantly stretches the penile tissue. The constant stretching affects the multiplication of tissue cells and leads to the gradual expansion of the penile tissue. Within several months, you’ll see your desired length and girth. 

Legitimate scientific studies have recorded increases in penis length of about 25 percent in men who’ve used the device for four to six months. However, it should be work six to eight hours a day – on a daily basis – to ensure you get the results you want. If your penis cannot handle it for that length of time, it needs to wear it for as long as you can handle it.  The more it’s worn, the quicker the results.   

SPECIAL NOTE: The best way to wear the device is to use it for 2 hours, remove it for 15 minutes to give your penis a rest and place it on again for additional 2 hours – repeating the process until you’ve worn it for 8 hours.

Penis extenders are ranked based on three things:

  • Effectiveness
  • Convenience of use
  • Price

They come in very basic and elaborate designs, but even just the basic models will get you the results you want.

We have gone through the top penile traction devices on the market – and there are two that stand out above the rest. Our favorites were chosen based on their ratings in the three categories mentioned above. What are they?

#1 SizeGenetics

After doing a plethora amount of Internet research on new and old devices, reading the various forums and reviewing the customer reviews, my first choice in penis extenders is the SizeGenetics model.

While it’s still a relatively new penis traction device, it outperforms its competitors in terms of convenience, effectiveness and price. SizeGenetics is the successor product to the first non-surgical penis enlargement product developed by both American and Danish surgeons and designers in Denmark 1995. Unlike other devices, SizeGenetics has passed independent clinical tests to prove how effective it is.

It’s a specially-designed device that inflicts painless, non-damaging traction on the penis to gain permanent penis extension. The new materials and design make it as light as a feather, meaning it can be worn for longer periods of time without problems.

How Effective Is It

While studies have shown there is an average 25% increase in penis length, many customers have noted they’ve seen an actual increase in penis length by 29% This means men who used SizeGenetics on a daily basis for three months saw an increase of one inch in length and half an inch in their girth. Men who used the device for six months had a 1.5 to a 2-inch increase in length and an inch in girth.

SPECIAL NOTE: The growth you experience will depend on your current penis size.

Safe, Registered and Medically-Based

SizeGenetics has been given the “green light” for us based on the stringent FDA regulations, ensuring it’s a registered medical device. Both American and Danish doctors and scholars have given their approval based on the multiple medical endorsements and clinical trials conducted. SizeGenetics is also approved by the EU’s health authorities, which found it to be safe for use by anyone.

Money-Back Guarantee

SizeGenetics offers a six month (180-day) money-back guarantee. If you’re not happy with the results the device provides, you can get a full refund minus the shipping and handling fees.

My Final Thoughts

SizeGenetics is an extremely powerful product with maximum usability with a price that undercuts the rest of the penis extender market. For a limited time, you can purchase the Ultimate Package for $299.95 - $200 off the typical $499 price. Not only does it work, but it’s competitively priced too.

#2 ProExtender

The ProExtender was my second choice in penis enlargement devices. While it's similar in how it works to the SizeGenetics model, the price is what makes it different. The ProExtender is a bit higher, but it's also given a five-star rating by a majority of men who've used it. 

It's a unique system that ensures men looking to increase their penis health can get. It can help with penis size, ejaculation control and Peyronie's Disease.

Studies Prove It Can Work

Dr. Jorn Ege Siana of the Scandinavian Clinic of Plastic Surgery in Copenhagen carried out a study „Tractive Elongation of the Penis by Means of Stretching. It found that men who use the ProExtender device had a 1.1-inch increase after 1,100 hours of traction exposure. Their flaccid size also increases .75-inches.

Men purchase the ProExtender to get the increase in traction, stretch and blood circulation it provides. They also like it because it’s comfortable to wear and can give rapid results. Early penis traction methods used weights or similar primitive procedures that led to new tissue growth but were unpredictable.

How Safe Is It

The FDA has given the ProExtender medical approval for use in penis enlargement treatment. Thousands of men who’ve used the device have noted they’ve seen an increase in their penis size (length and girth). Surgeons and urologists, feeling confident in its safety, have been recommending it to their patients and the public.   

Money-Back Guarantee

If you’re not happy with the ProExtender device, send it back within six months (or 180 days) to get a total refund of your purchase price.

What I Think About The ProExtender

ProExtender is extremely user-friendly and has been proven to increase a penis size (both length and girth) and straighten a curved penis. Doctors around the world have recommended the device to their patients to attain actual and permanent penile increases.

As long as you follow the manufacturer’s directions and use the device on an everyday basis, you will get the results you want. It won’t happen overnight, but a little bit of patience and time will ensure that you see an increase.
