Penis Stretching For Penis Enlargement

Stretching consists of attaching a penis stretcher or "extender" device to the penis for set periods of time. The device exerts a constant traction on the penis, which, in theory, lengthens and widens the penis.

The traction supposedly causes the cells in the penis to divide and expand. In 2002 a study published in the International Journal of Impotence Research concluded that penis extender devices are effective at elongating the penis and furthermore increases the penis length in correlation with the amount of time the device is worn.

A study conducted at the University of Turin and published in 2009 in the British Journal of Urology showed similar results, using a penile extender exerting a continuous and gradually increasing traction force on the penis. The device consists of a plastic ring, where the penis is introduced, with two dynamic metallic rods which produce the traction

After using the device at least four hours daily for six months, the mean gain in length in flaccid state was 2.3 cm, with significantly improved erectile function scores and treatment satisfaction scores of "acceptable" to "good improvement" in all items, except for penile girth, where there was no significant measurable or subjective changes.

However, the study population only included patients with inadequate penile dimensions, so it remains uncertain whether the same effects would occur on all subjects.
