Our recommended technique for penis widening utilizes the insertion of Belladerm dermal-matrix grafts placed beneath the skin of the penile shaft. Belladerm is human allograft skin that is minimally processed to remove the epidermal and dermal cells while preserving the extracellular matrix of the dermis. Belladerm is a product of the Musculoskeletal Transplant Foundation (MTF) which runs the largest tissue bank in the United States. Since its inception in 1987, MTF has recovered tissue from over 90,000 donors and distributed more than 5 million grafts for transplantation. All procedures for donor screening, serologic and microbiologic testing meet or exceed current standards established by the American Association of Tissue Banks.

We began performing penis widening with Belladerm dermal-matrix grafts in 1998. We have found many advantages to the use of Belladerm over the previous techniques of fat injections and fat grafts. Because Belladerm is inserted as sheets, it results in a smoother, natural result compared to fat which is injected and therefore can result in unevenness or nodularity. In addition, the consistency of Belladerm is similar to that of the penis compared to fat which often feels "spongy".

The Belladerm is inserted through the same horizontal pubic incision that is used with penis lengthening. These two procedures are often performed together. 2 layers of Belladerm are wrapped around the penis shaft beneath the skin and secured in place with sutures. The Belladerm normally attaches to the penis within 4-6 weeks. Typical gain in girth is 25-35% in circumference.
