What should I look for in a penis extender?

How do penis extenders work?

Penis extenders work generally in the same way. They are designed to apply constant traction on the corpora cavernosa in your penis causing cells to duplicate, also known as cytokinesis. As these cells accumulate this enables your penis to hold more blood, increase in size by inches, attain harder erections, reduce premature ejaculation and even decrease penile curvatures.

Yet despite having this same end goal, not every penis extender is the same.

The extenders vary due to the different ways of using the device and the materials they come in.

What to look for in design:


Some devices use Medical Type 1 materials to make sure that you can comfortably wear their device all day long. Others prefer to use cheaper materials, that means they can offer lower prices but also generally lower quality.


There are devices on the market that have obtained medical certification having been assessed under the Medical Device Directive 93/42/EEC. Check to see if the device you are interested in carries this strap off approval.

Strap or Noose

Most penis extenders offer you only one of these methods for wearing their device. There are different options that can focus on reducing slippage and increasing comfort, each of us will prefer different options, so make sure the device you choose offers more than one option.


A few extenders have options to help deal with curvatures and Peyronie’s. These offer possibilities to attach the device even if it isn’t straight.

A major game changer are multi-angle devices, these are able to freely move as your body moved.


Even with a strap, traditional penis extenders cannot guarantee 100% comfort for everyone. That is why many leading penis extenders have chosen to include Comfort Technology. Most penis extenders offer different ways of wearing their device; such as silicon nooses, comfort straps, protection pads, fabric covered latex head grips and non-slip mats) so no matter the size, shape, angle or sensitivity of your penis, you can safely wear their device without discomfort or chaffing.

Other things to look for:

Clinical studies

It is important when looking for a penis extender that you make sure that they can offer you proof that their penis extender can produce the results, and that their device has been tested.


Guarantees are a great way of judging how confident the manufacturer is. The longer they give you on a money back guarantee, the longer you have to test the device and see if it works. Now for optimal results, you should use a penis extender for 6 months. For this reason, should they offer you less than 6 months, it may be for a reason i.e. it doesn’t work.

Your penis is an important part of your body and naturally only deserves the best, so before you invest in any product, make sure you keep the information above in mind and make sure that it is clinically tested, supported by a guarantee and is made from the best materials.
