What Is The SizeGenetics Penis Extender?

The Size Genetics Penis Extender is the flagship product from men’s health company SizeGenetics. The company have been on the scene since 1995 and in that time have amassed a wealth of satisfied customers and proven themselves as a reputable and scientifically-sound option for genital enlargement. They currently offer 4 different devices for penis increase and claim to offer the most comfortable device currently available for purchase.

The Size Genetics Penis Extender uses the scientifically-endorsed penis traction technique to enlarge penis size. Similar to resistance training, this technique breaks down tissue in the penis by applying gradual pressure, and over time, the tissue will repair itself stronger and more durable. This results in a longer, girthier and straighter penis in the long term.

How Does The SizeGenetics Penis Extension Device Work?

The Size Genetics Penis Extender doesn’t come pre-assembled so you’ll need to prepare the device yourself. However, it’s a very straightforward procedure as the device consists of three separate parts: the device, metal rods, and a silicone strap.

To begin, first measure the length of your flaccid penis to ensure you’re working with accurate measurements. Then place the basal ring of the device around your flaccid penis, making sure that the indent in the ring is positioned below the penis shaft. Next, place the penis through the silicone strap and tighten it in place behind the penis head. Then simply insert the metal rods into the device, which will allow you to increase or decrease tension as you see fit.

Next, tighten the rods so you feel pressure on the penis, but so much that it becomes uncomfortable. Within a few hours, the pressure will lessen, allowing you to increase this tension further. This is how you gradually break down the penis tissue and begin the cell regeneration process.

How Often Should I Use Size Genetics Penis Expander?

It’s advised to use the SizeGenetics Penis Extender for a minimum of 2 hours per day, every day for a total of 6 months. By this time, you should be seeing visible results at around a 10-20% increase. After this point, you can continue using the device as you see fit, although consistent growth is not guaranteed.

While 2 hours per day is the required minimum, it’s advised to increase this to 5-6 hours per day after six weeks. While it isn’t a requirement to see an enlargement, it ensures that you’re maximizing the possibility of achieving notable results. Fortunately, due to its comfort and discretion, it’s possible to wear the Size Genetics Penis Extender underneath your clothes while you go about your daily activities.

What Results Can I Expect With SizeGenetics?

The SizeGenetics Penis Extender ensures at 10-20% enlargement after 6 months of regular use. In addition to size increase, users also reported a moderate increase in girth, improved erections and increased sexual stamina. Users who continued using the device for an additional 6 months reported an average increase in penis size of 28%. When compared to other products on the market, this is an impressive figure.

Size Generics also offers a product dedicated to straightening bent or curved penises. One of the most common reasons for unnaturally shaped penises is Peyronie’s Disease, and the Size Genetics Peyronie’s Disease Home Treatment Kit provides medical and aesthetic assistance for those looking to straighten out their penises. Furthermore, similar results can be achieved with the other generic Size Genetic products, but not to the same lengths.

Benefits Of Using SizeGenetics Penis Extender

The main benefit of using the Size Genetics Penis Extender is the notable increase in size. The average reported size increase is around 20%, which is a considerably high figure in comparison to some competitor products. Those who use the device long term can even expect to go higher, generally capped at just below 30%.

The product also uses MDA technology (multi-directional angling) to help with penis straightening too. The Size Genetics Penis Extender is actually one of the few traction devices on the market to incorporate this into its design, something which makes it stand out from the crowd. Users suffering from bent or curved penises have reported considerable results from utilizing this aspect of the product.

In addition to size increase, girth increase and straightening, many users have reported increased sexual stamina and erection sustainability after using the device. One of the side effects of increased penis size is sexual confidence, which then results in improved sexual abilities. While this isn’t so much a genetic improvement, it’s an appealing mental health benefit for many users.
