Graft material can come from a variety of sources:
- The patient’s own body. Sometimes tissue is taken from the undersurface of the skin or the lining of the testicles.
- Cadavers. Cadaveric pericardium is a common source, taken from human organ donors. The pericardium is the sac around the heart. This tissue is flexible, just like the tunica albuginea tissue in the penis, which surrounds erectile tissue.
- Animals. Tissue from cows and pigs are sometimes used as grafts.
- Synthetic materials. Some grafts are man-made.
All graft material is sterilized before use. Patients can ask their surgeons about the kind of graft to be used and why it has been chosen.
