Does Sizegenetics really work?

A comprehensive review of the SizeGenetics device

What is the Sizegenetics?

The SizeGenetics™ device is the original penis extender and one of the most trusted oldest devices on the market. It has been around for over 18 years guaranteeing gains in a matter of months.

It comes in a variety of packages to meet your budget and comfort requirements.

There are four different packages:

  • The Value Edition - this is the basic device and comes with one comfort strap, one protection pad and the 1" and 2" elongation bars.
  • The Comfort Package - this package includes the same great device as the Value Edition, but also includes the silicon noose, Velcro™ strap, 1", 2" and 1/2" elongation bars, the NoSlip Protech mat, the 3M plaster and a Luxury Leather Case with Lock and Key.
  • The Ultimate system - is the most complete package. You get the certified device, all the comfort accessories from the comfort package plus some great after care products such as the Revita Cream moisturizer and Traction Plus Powder. You'll also get the PenisHealth™ DVD with some fantastic supplementary exercises, Seduction and Fitness E-books, Device Cleaning Wipes, and the Luxury Leather Case with Lock and Key and a Travel Case.
  • The Curvature & Peyronie's Edition - all the above and Go Today™ Vitamin E Oil, Extreme Amino™, Enzyme P500™, CoQ10 Enzyme+™

Does it have any Certification?

All of the packages include the device that is certified with the CE marking that indicates conformity with health, safety, and environmental protection standards for products sold within the European Economic Area.

It is made from medical grade materials that are hypoallergenic, lightweight and easy to use. Ensuring a high quality product that will last you years and won' let you down!

The SizeGenetics™ device carries the European CE mark therefore classifying it as a Class 1 medical device. It is a registered medical type one device SizeGenetics™ and has been approved for use by strict FDA regulations. Every single device is manufactured to the strictest standards in high-grade facilities.

What Attachment options are there?

There are somedifferent accessories that can be used for attaching the device to the penis. The Comfort package has all three options, as does the Ultimate System and Peyronie's Edition.

By far the most popular is the new and improved comfort strap as it can be adjusted to fit any size. There is also the option to use either a silicon noose or a Velcro™ strap.

The comfort strap is wider than the silicon noose, which means that the surface area is increased, reducing the pressure. However, as it clips into place, it doesn't always fit all as well as the silicon noose.

The Velcro™ strap is the final option and is wider like the comfort strap and fully adjustable like the silicon noose. The material is of course, not so soft, but it makes a good choice when combined with the comfort accessories.


What Comfort accessories can I use?

There are several choices that you can use to increase the comfort when wearing the device. Due to its nature, constantly providing traction to the penis by stretching it, there is bound to be some discomfort during the period when you start using the device.

The comfort accessories are highly recommended as if you are not happy with how the device feels, you won't use it!

The most widely used is the protection pad, which is a foam disk that you wear around the glans before attaching the head-piece. The material greatly reduces the pressure by increasing the cushioning.

There is also the NoSlip Protech mat. This is a latex mat which can be wrapped around the penis before attaching the head-piece. Due to the properties of latex, any slipping is reduced to almost none.

The design of the device means that it will fit most men, and on its minimum setting will fit a penis of two inches. It is fully extendable by adding elongation bars to the size that is needed, and reaches a maximum of nine inches. You can always buy extra elongation bars separately when your gains have reached a point that can't be supported by the standard bars.

What makes the Sizegenetics different?

One of the most interesting design traits of this device is the MDA, or the multi-directional angling headpiece. This allows total freedom when wearing the device as most of us don't want the device to be sticking straight out away from our bodies. The possibility to change this angle means that it will move as our body does, so when moving to sit down, for example, the device will move with us, helping keep it concealed beneath loose-fitting clothing.

The device is also one of only a select few that offers a huge 2,800g of traction. This is more than most other devices on the market. Of course, a higher level of traction means more pull when the device is being worn. This will help to increase the rate of growth.

Is it back by Clinical studies?

There are clinical studies that have been conducted and have proven that this extender works and it is endorsed by many health professional all over the world.

Our Verdict

This device really does work! Backed up with scientific evidence, made of medical grade materials in Europe. There are many lookalikes and imitations, which may have a more attractive price, but they don’t perform as promised and many simply don’t hold up. Worse, many are overpriced and more cheaply produced.


A definite recommendation for all those looking to really add permanent gains!
