How a Penis Extender Works

With an increase in publicity, many people are taking notice to the traction device, as a result a number of individuals have begun to question if this is actually an untested and new product.  But if we want to look at the actual techniques we can find they are part of an ancient tribal custom, part of spiritual practices and even a form of modern day tissue rebuilding used in some surgical patients. This idea has a long history over the span of centuries. The only thing that is actually new is the ability of the product in an effective and safe method designed for at home use. We’ll take a moment to look at the long history along with the idea behind it with and the dramatic results it can offer.

Many people have an understanding of how the extreme type of traction that has played a role in the African tribal and Amazonian tribes. These include their ear and lip discs along with neck ricks that are designed to help stretch the body to incredible sizes or length. Consider either the Discovery Channel or National Geographic.  You probably have seen some of these enhancement devices on these people. Well these native people have used the same devices on their penis as well. They include the, Peruvian Cholomecs, Sadhus holy men of India and Papua Indians of New Guinea who hold rituals designed to get their penis up to 22 inches!

How A Penis Extender Works
In modern times, traction is what they medical community calls a calibrated and continuous pressure that has been applied to the body to help healing after burns, injury, surgery or trauma and it allows the body to regain stretching of tissues and to rebuild tissue and muscle naturally. There are mastectomy patients that take muscle from the chest just before reconstructive surgery. Penis enlargement patients who use this traction are looking for it to help to heal, straighten and even strengthen their penis, while a burn patient who creates their own skin will form grafts with the use of this and the tradition will help to enlarge the available amount of skin prior to their transplant.

When the body is stretched, it opens up spaces that are between the cells and helps to trigger both growth and healing in the human body by working with the adjacent cells that begin to divide and fill in the empty space. When it is used on a regular basis, this growth can be in the millions and these new cells can help to significantly add tissues and size to their area.

This is essentially how the concept of penis enlargement devices works. In this since well documented and popular device which was designed by a Urologist and crafted by a Denmark company, traction is applied with an adjustable set of calibrated bars all between a anatomically correct curve base the will fit the root of a penis comfortably. There is then a surgical grade band that slips over the penis head and while the penis is growing it can have the traction and distance slightly adjusted. This product is known under the name of ProExtenderTM, and you have the ability to get this from either your doctor or online.  There is also Andro Extender, known as Size Genetics, which is a top choice for extenders.

We find that Penis enlargement traction devices do actually work. With medical studies along with medical applications of these traction devices that show there is real and very permanent growth. This happens in both length and girth expanding in noticeable inches. These are of course not just a quick fix, but when used properly (and these directions you will find specific to the unit you end up choosing) over time the body will begin to build new tissue. Never trust an advertisement that claims “instant” gains or “miracle” overnight growth because they are not only very unsafe, but they can be unrealistic and unreliable as well.

Any man interested in gaining size in his penis should keep his health and safety in mind above anything else. You should focus only one medical device that been medically corrected and to follow all instructions of the unit. Questions should be taken up with your doctor. The success of a traction device will depend on your dedication to the unit itself. With proper and consistent application you will find that a penis enlargement is possible for you. If you are still trying to decide between products both the ProExtenderTM and size genetics are excellent options.

Are Penis Extenders A Scam?

Any guy who has ever considered purchasing a product that enlarges penis size has wondered if such products truly work or if they are just a scam. The problem is even more compounded by the number of devices and products on the market that makes exaggerated claims and use cheap technology or ineffective ingredients that could not possibly provide the results that they claim.

Confused and worried that penis extenders are a scam? Take a look at just how these devices got their start and what you need to know to use them…


Modern penis extenders were invented in 1994 by a Swedish doctor named Dr. Jorn Ege Siana. Siana specializes in General and Plastic Surgery and may have originally designed the devices to help patients recovering from penis enlargement surgeries. Also called penis stretchers and penis traction devices, these products work by holding the penis in a slight stretch, the constant stretch promotes cellular division, offering a gradual increase in penis girth and width. These devices quickly caught the attention of average man and were swiftly sold around the world.

The original products did not offer the same quality as the products sold today. As modifications have been made throughout the years, these devices have become more capable, able to increase the amount of traction provided for a greater stretch. Today’s devices are also comfortable for extended wear and can fit all penis sizes including penises smaller than average length. Modern penis traction devices are also made out of a range of materials ensuring these devices do not cause skin allergies and will not fall apart.

Side Effects

Penis traction devices sold today have undergone extensive testing and scientific study. These devices can be considered medical devices due to their superior engineering, recommendation by medical professionals and their ability to increase penis size and subsequently reduce penis curvature. Thankfully, these products are designed to provide all of these benefits with very few side effects. Usually the only side effect experienced by man is a pinching feeling. This can usually be eliminated by looking for a traction device with some type of cushioning or memory foam.

Useage and Results

The devices can easily be worn while unclothed or worn under clothing. The position of the device can also be adjusted for greater comfort or to provide privacy when worn under clothing. In some instances, it may even be possible to wear the device when working, exercising, doing chores around the home, driving or other activities.
