The following is a precis of a paper presented to the 1st Virtual Sexology and Hispanoamerican Sexual Education Congress (February 2001) by Dr. Eduardo A Gomez de Diego of Andrology Services, Andromedical Clinic, Madrid, Spain

Introduction
The principle of traction to enlarge a limb or other part of the human body has been known for centuries.

Not only has this knowledge been used to increase the length of bones, it has also been applied to other aspects of modern medicine - for the generation of new tissue to cover burn wounds or areas of hair loss ( placing a tissular expander underneath the normal skin ).

In other cultures this principle is applied to lengthen different parts of the body such as the necks of the Giraffe Women of the Paduang tribe in Myanmar; or the lengthening of the lips in certain African tribes of Africa that use wood to create traction; and in India where they hang stones on the penis of men as a form of penitence with the resulting enlargement of the organ.

Based on this principle of external traction the SizeGenetics System was designed. It is able to exhort a gradual traction force of 600 to 1500 grams.

When human tissues are submitted to traction of this magnitude, they react by increasing in size. This is the basic principle behind the theory that the penis can be enlarged.

The device consists of a plastic ring, where the penis is introduced and 2 dynamic metallic rods that determine the level of traction.

At the opposite end there is a plastic support where a silicone band holds the penis in place.

Results
Based on our clinical experience the traction device yields the following results:

• An increase in the length of the penis in erection and flaccidity.

• An increase in the girth of the penis in erection and flaccidity.

• This results will be analyzed statistically to be verified and quantified.

The raw data results can be found at:

The increase in length, both in the erectile and flaccid state, is directly proportional to the time of use.

The increase in length both in erection and flaccidity, does not depend on the natural size of the patient.

The average growth in length of the penis in cm/month in 95% of the patients was between 0.4283 cm and 0.5163 cm in erection, and between 0.4173 cm and 0.5495 cm in the flaccid state.

The increments of change in length of the penis in erection are more uniform than those in flaccidity which tend to be more disparate.

The increment of change in the length of the penis in erection is not relative to the age of the patient.

The use of the penile traction device will increase the girth of the penis, both in erection and when it's flaccid.

The average growth in girth in cm/month in 95% of the patients was between 0.6111cm and 1.0200 cm in erection, and between 0.6386 cm and 1.0425 cm in flaccidity.

Treatment was over 3-6 months duration.
