What is the foundation behind this principle?
It is based in the medical principle of traction, that when executed in a controlled, gradual and progressive Manner on the penis will stimulate the growth of the suspensory ligament, corpus cavernosum, and the rest of the penile tissues.

Has the principle of traction been used in medicine before?
Yes. In modern medicine this principle of traction is used to create new tissue for skingrafts, for the elongation of bones and to create new skin with hair to cover bald areas. Also this principle has been used in ancient cultures to create long necks like in the Giraffe women of Birmania and to create longer lips in certain African tribes..

What is the maximum growth in centimeters that I can obtain?
It all depends on the individual, approximately 4 centimeters. One inch equals 2.5cm

Which is the minimum growth that can be obtained?
The minimum growth is of 1.5 cm. The average growth is 3 cm, based on 95% of the patients.

Is there growth both on erection and flaccidity?
Yes, the growth is proportional and it will be evident in erection as well as in flaccidity.

Will it help to correct penile curvatures?
Yes. In a period of 6 to 7 months of treatment we are able to correct 70% of the curvature. There will be a marked improvement.

Are the results permanent?
Yes, because there has been growth of the penile tissues.

Will the glans also grow?
No. Only the penile shaft. The sensitivity of the glans will not be affected.

Will the lengthening make the penis thinner?
No. The growth is proportional troughout the whole penis. There will be an increase in length as well as in girth since the new tissue formed creates more volume and occupies space.

What is the ideal age to begin the treatment?
From 18 years on. The treatment can be done in older men. Our reseach included men of 60 and 70 years of age and it showed that traction will stimulate the growth of tissues at any age.

Is there any pain?
No, this product is a mechanical device and is painless. The user at first may experience the presence of product, but in time this sensation will soon disappear.

Should I remove product when urinating or defecating?
Yes, when finished replace back onto the penis.

How can I use product without my family finding out?
Use it during working hours or when out of home.

Can it be worn at night?
Yes, although many patients wake up with product dislocated owing to the amount of times the user moves at night or nightly erections. In these cases, the product should only be worn 3 hours per night. We recommend that the product shouldn´t be worn at night during the first few days of usage or until you feel totally comfortable with handling the product.

If I have an erection with the stretcher on, what will happen?

This product will not rust. European Union Certification guarantees that product is free of defects and guarantees that product has been inspected up to par. Stretcher can be washed once a week with mild soap and water.

Must product be oiled or greased?
At first it is not necessary, but we do recommend that you apply small amounts of oil on the bars in order for it to slide up and down with ease.

This product is totally mechanical. It is used to stretch the penis in its unerected state. It does not require batteries nor electricity.
