1.  Rebuilding and expanding the spongy bodies in the penis known as the corpora cavernosa and the corpus spongiosum.
  2.  Lengthening the ligaments of the penis, the most powerful being the suspensory ligament.

Did you know that penile lengthening surgery (the Bihari procedure) is performed by actually SEVERING the suspensory ligament? Most people don’t realize (and some “surgeons” don’t want you to know) that there are MUCH more efficient ways of lengthening this ligament, without ANY of the complications or painful side effects of surgery.
