SizeGenetics Review & Buyer’s Guide – Is This The Best Penis Extender For Erectile Dysfunction?

Size matters – anyone knows that. So men seeking to improve their sexual performance might have tried looking into solutions to help increase their length. Frustratingly enough, not all of the products on the market actually work, and that’s why it pays to do sufficient research before diving into a purchase.

One of the facts that will often surprise people after learning more about penis enhancers is that pills are not an FDA-approved solution. What does have the FDA’s seal of approval is the penis extender. Extenders are designed to mechanically increase the length of a man’s member, and they come in a variety of designs, but they also differ in terms of the results they provide. For this review, SizeGenetics takes front and center. Learn more about how it works and whether or not it can provide satisfying results by reading this comprehensive product review.



SizeGenetics is a brand that’s been selling penis extenders online for the past 17 years. They claim that their extender has been endorsed by doctors, and is categorized as a class 1 medical device under the FDA. It helps to extend the male organ by applying gentle, constant traction that pulls on the corpora cavernosa – the part that’s responsible for holding blood during an erection.

This constant gentle stretch encourages the tissues to elongate over time, allowing it to hold more blood and thus support a larger, more significant erection. Similarly, it will also helps you to work away fibrous plaque that could cause a bent pecker. In effect, this can help you achieve greater confidence and satisfaction during sex.


Each package comes with a set of essential parts and accessories for successful elongation. These will include a base, a headpiece, and elongation bars. To use it, the base is secured at the base of the penis, and the headpiece is attached just under the schlong’s head. The elongation bars connect from the base to the headpiece and can be adjusted to increase or decrease the tension on your dong.

To get the maximum benefit out of the system, it’s imperative that you keep the device on for at least 3 hours in a day. The solution should be worn for several months to achieve its optimal effects. According to the brand, most people will notice 29% increase in their length after the first 24 weeks of use.

The elongation bars that come with attached can support up to 10 inches of length. It’s important to keep in mind however that men with members that exceed 9 inches might experience more discomfort. Aside from that, concealing it might be more of a challenge with longer peckers, requiring the use of baggy clothing to hide the mechanism while in use.

At first, it is likely that users experience some discomfort while using it. Some guys skip two or three days between use to help their body adjust to the change. Once you’ve fully acclimated to the feel it, it’s important that it be worn daily to achieve the effects it promises.


The brand compares their extender to a man working out in the gym. As he lifts weights, he creates micro-tears or fissures in his muscles. Over time, these fissures are filled in by muscle tissue, resulting to increased length, length, and strength of the muscles themselves.

Scientifically, this process is called cytokinesis and may sometimes also be called traction. Essentially, the growth allows more blood to flow through during an erection. With more blood, the dong becomes larger, harder, and longer, resulting to a more satisfying intimate experience.

One study conducted on 15 individuals who used the this extender for 4 hours a day during a 6 month period. After that period, each of the men were recorded to manifest an average of 1 inch growth in flaccid length, and an average growth of 0.67 inches in erect length.

In this study, it was proven that penis extenders – this system in particular – can actually cause a change in both flaccid and erect lengths.


Does it really work graph

While it is likely that you might experience discomfort and perhaps even pain during the adjustment period, the SizeGenetics system does in fact work. Wearing it 6 hours a day for a period of 6 months may show significant positive results in length. Of course, it will take time. But the results are often worth it.

There have been some cases where some users experienced better results out of their use of the system compared to other men. Trying out these tips and techniques might help improve the user experience and get the best comfort and results out of this extender.

Physically Prepare the Penis

The extender might cause some discomfort especially during the first few minutes or hours after it’s worn. Preparing it can help improve the adjustment and relieve the pain that the mechanism might cause at the start. Exercises like jelqing can offer better resistance to that initial pain and discomfort. Perform the technique for 5 minutes before wearing the to ease the adjustment process.

Read the Instructions Carefully

Looking at the it, people might think that the process for wearing and using it might be pretty straightforward. That’s because it was designed to look intuitive so as to relieve some of the confusion that first time users might experience. But that doesn’t mean that it’s okay to try the device straight out of the box without first reading or watching the instructions that come with it.

Before attempting anything, make it a point to go through all of the instructions first. Read any manuals and watch the entire instructional DVD to fully understand how to maximize the benefits of this extender as safely as possible.

Be Patient

Some guys might find it disheartening to wait for results that won’t show within the first few months or weeks. While it is possible for some men to experience changes in as little as 24 weeks, it’s also important to keep in mind that not all men are the same. Some will respond faster to the system than others.

Even if you don’t see any changes within the first few months, it pays to be patient. Keep using the system during the prescribed duration (6 hours) every day for at least a 6 month period to achieve significant results.

Combine the Use of Male Enhancement Supplements

There is probably no better time to use a male enhancement supplement than during the use of the system. As the extender applies tension to the tissues of the penis, the supplement encourages greater blood flow. This helps the structures of it to acclimate to the changes and increase in engorgement, thus helping the process along.

Take your time to select the best possible male enhancement supplement to get the best results out of your effort. Choose products that focus on increasing blood flow to support the effects of the SizeGenetics.
