It is important for one to realize that approximately one-third to one-half of the penis is inside the body, where it is attached to the undersurface of the pubic bone by suspensory ligaments. These ligaments make the penis arch under the pubic bone. Surgically releasing these ligaments brings more of the penis outside the body, allowing it to protrude further outward on a straighter path and providing more functional length. Wearing of penile weights after the surgery are important to maintain penile lengthening.
Releasing the ligament partially frees the penis from its pubic bone attachments, dropping it to a lower position, which may increase penile length or give the illusion of length gain. There are various ways of doing this surgery which may involve YV plasty which may be associated with deforming hair-bearing hump at the base of the penis. Contrarily to this a transverse incision is a better approach. One inch gain by this procedure is considered as success even with use of weights.
