High Quality, Scientific Design to Promote Optimal Results


Jes Extender is easy to use. It assists enlargement of the penis by using the well proven scientific principal of traction and applies the most optimal tension for effective penis growth. The human body is highly adaptable and can change to overcome external stimuli. For example athletes, bodybuilders, UFC martial artists and gymnasts put themselves through routine training and their body uses it’s own natural ability to and adapt and grow which allows them to become faster, more flexible, bigger and stronger. The process of biological adaptation is how Jes Extender works, it assists the body to allow for the penis to grow naturally.

When Jes Extender encourages new growth and enlargement of the penis, only a slight yet comfortable stretch is felt.


Most Effective Tension Levels


To assist the most optimal penis growth, simply use Jes Extender as directed between the medically tested and proven tensions of 900 to 1500 grams. Tension is increased in small increments as the penis grows. It’s all explained in the easy to understand DVD instructions or we can be contacted 24/7 for help and support.

The Jes Extender has the capability to exert over 4000 grams of traction, however, much scientific analysis and numerous clinical trials has shown beyond a doubt that tensions between 900 – 1500 grams are best to promote the most effective and optimal penis growth. The Jes Extender has been specially calibrated to these exact tensions to support the most optimal results. Click picture below for larger version.

How Jes Extender Increases Penis Length

Penis Length


The penis length of a man is largely decided by a ligament in the penis called the suspensory ligament, This ligament connects to the body at the pubic bone and attaches to the penis shaft. When flaccid and pulling the penis away from the body or when erect and if pushing the penis downwards, this ligament can be felt very easily.

This ligament is the same that surgeons cut in penis enlargement surgery to increase penis length for the patient. The main aim in penis enlargement surgery is to encourage the ligament to heal in a lengthened state which allow more penis length to rest outside of the body once the patient has healed.

The way Jes Extender assists enlarging the penis naturally is to help slowly lengthen the suspensory ligament rather that to simply cut it. Jes Extender has been designed with very specific tension levels to support safe lengthening of the ligament. Penis length alone does not decide a man’s overall penis size so next we consider how Jes Extender can assist with increasing penis girth.

Penis Girth


Penis girth determines the overall thickness of a man’s penis. There are two chambers in the penis that fill up with blood when getting an erection. The capacity of these chambers is what gives a man his penis thickness. While using the Jes Extender Penis Enlarger, it supports a biological process of growth called cell division. “Cell division” means exactly that, cells get divided and multiply. This natural biological growth process helps support more overall volume of the specific body part i.e not simply a stretching of that body part.

How Penile Traction Can Assist Penile Curvature


What is Penile Curvature?


Severe penile curvature is diagnosed in Australian men as a medical condition of abnormal curvature of the penis. It may be observed with the characteristic of a 30 degree bend (or more). In most instances is not painful but in more rare cases it can be very uncomfortable. It can become an issue for some men in regards to urination, having sexual intercourse and other normal bodily functions that involve the penis.


Penile Curvature Causes


To date, there is no definitive cause of Penis curvature but there are some factors that can be taken into consideration. The first factor is that some men are simply born with the condition. The second factor is that it can be brought on by a sudden injury to the penis. The third factor suggests that it can be induced by a more gradual injury or strain to the penis. For example, men who do a lot of cycling or driving can be susceptible to penis curvature due to their penile shaft always being “squashed” and under weight for prolonged periods. The latter factor can also include men who masturbate in unusual ways or who’s partner may twist or bend the penis while using it. Over many years these “slight injuries” can cause the penis to heal with a curve or bend in the penis shaft.

Please note: we ask all men who purchase Jes Extender to assist with penis curvature to first consult with their healthcare provider and to also consider if any of the above factors may be playing a part in the condition. And if so, to take whatever counter measures possible to avoid taking “two steps forward and one backwards” if undergoing penile traction therapy.


Penis Curvature Treatment


In many cases, if going to a Doctor for advice about penis curvature they have traditionally referred their patients to a surgeon for corrective surgery. However, it is important to be aware of other non-invasive options such as penile traction therapy, which may assist in the treatment of Penis curvature. The cost is far lower than a surgical procedure and there’s no healing or down time like there is when undergoing surgery of the penis. In fact, some Jes Extender users have had corrective surgery in previous years, only for the condition to return later on.

Penile Traction Therapy may assist in stretching and loosening up the plaque that can contribute to penis curvature. Once this is achieved, newer and straighter growth of the penile tissues may “take over” and assist the penis to remain and heal in a straighter position, thus supporting a reduction of penis curvature.


How Penile Traction May Assist Erection Quality


While penile traction therapy (PTT) was not originally considered for the purpose of assisting erection quality issues, it was during other various clinical testing that this potential benefit was discovered. Many men when advancing in years can experience a reduction in erection quality and this can even lead to impotence or the medical diagnosis of Erectile dysfunction.

Erectile dysfunction

Penile traction therapy (PTT) may assist the body to adapt and multiply it’s cells within the penis which can support new penis growth. This new growth may also encompass the veins and arteries throughout the penis. Due to this method, it can be considered that everything within the penis may get assisted as a result of the cellular multiplication within the penile shaft.
