Approximately half of the penis is positioned inside the body. It is attached to the pubic bone by the suspensory ligament. When this ligament is released, the penis drops, or extends, further outside the body, increasing the outside length. A small silicone spacer attached to the pubic bone will prevent reattachment of the ligament.
The results of surgical lengthening vary and depend on several factors: on average the division of the ligament leads to a typical gain of 1-2 inches. The additional insertion of a silicone spacer improves the results significantly and reduces the risk of potential shrinkage due to scarring. It needs to be emphasised that surgery is only one step in gaining significant additional penile length. Patients need to use adquate stretching devices (e.g. penile extender or vacuum pump) regularly over a period of at least 4-6 months after surgery to achieve the best possible result and to allow further lengthening of another 2 inches.

The lengthening effect can be enhanced by cosmetic skin surgery on the back of the penis (VY- or Z-plasty) and/or surgery between the scrotum and penis with reconstruction of the penoscrotal angle to expose more to the penile shaft (division of scrotal web).
