Penile graft surgery: why many specialists prefer graft-free reconstruction to avoid the “patchwork” effect that may affect the final outcome.
Penile graft surgery is used less frequently today due to functional and aesthetic limitations reported in some cases.
A penile graft is tissue taken from another part of the patient’s body or sourced from porcine or bovine materials.
The technique may require tissues of different sizes and thicknesses, which can create a visible and palpable “patchwork effect” and “ridge effect.”
Complications related to the penile graft can go further, potentially affecting both aesthetic and functional aspects of penile reconstruction. Learn more below.
What is a penile graft?
A penile graft is a tissue transplant used during reconstruction for the treatment of Peyronie’s disease.
There are two main types: autologous skin grafts and xenografts made from animal tissue, such as porcine submucosa or bovine pericardium.
Whichever option is selected, the surgeon places the graft on the side affected by the curvature. The goal is to regain penile alignment and size.
Is penile graft surgery effective?
The effectiveness of penile graft (penile graft surgery) is limited, and its indication has been progressively reduced in contemporary clinical practice.
Historically, when a penile prosthesis was required, the available techniques for placement and reconstruction often left significant damage.
Grafts were used to repair these defects, requiring precise surgery to prevent bleeding and skin deformities caused by the prosthesis.
Over time, physicians observed that when the damage was small, a graft was unnecessary because the body could heal and the tunica albuginea would strengthen enough to support the prosthesis, helping avoid issues.
This approach also reduces the risk of infection and other complications discussed below.
Risks of penile graft surgery
Potential complications of a penile graft include:
- Long suture lines
Multiple suture lines may remain palpable even after complete healing.
- Different sizes and thicknesses
Grafts can vary in size and thickness. Beyond the “ridge effect” from thickness variation, the penis may also show a “patchwork effect” due to size mismatch.
Both issues are often noticeable on palpation.
- Lower mechanical strength
Like size and thickness, graft resistance may vary.
If a penile prosthesis is later required, there is a risk of bulging or even graft rupture.
- Matching asymmetric defects
When the deformity is asymmetric, a graft must cover the entire area.
Because a custom-size graft is not feasible, surgeons may need to join several pieces, creating seams.
This “patchwork effect” can fail at the suture lines that join the graft segments.
- Avascular tissue and limited healing
As transferred tissue, the graft is initially avascular (without its own blood supply).
This can lead to scar retraction (shrinkage).
Reduced perfusion may increase infection risk and impair healing.
- Limited expansion due to the graft
Penile lengthening can also be negatively affected because the graft may limit tissue expansion, restricting maximum achievable length.
Given these limitations of penile graft surgery, it’s important to consider more modern alternatives with lower complication rates.
How graft-free surgery works
Graft-free penile surgery is a reconstruction technique designed to restore, when possible, penile shape and proportion.
It uses small, geometrically planned incisions to restore length and width while preserving nerves.
This approach aims to reduce complications associated with penile grafts and may lower infection risk by preserving well-perfused tissues.
With better blood supply, the body is more capable of defending against infection, potentially reducing inflammation and infectious events.

Egydio Technique: reconstructing the penis without a graft
Penile reconstruction with the Egydio Technique aims to optimize length and girth within anatomical and functional limits.
This is achieved through tissue expansion using the patient’s own penile tissues, avoiding a penile graft.
Multiple small, mathematically planned incisions are made in the tunica albuginea to distribute expansion according to the patient’s anatomy.
Because these incisions are made in vascular tissue, the approach may lower infection risk and support healing.
Incision direction is selected according to expansion needs.
For length gain, horizontal incisions are used within nerve-safety limits. For girth, vertical incisions can promote circumferential expansion.
Infection risk can also be minimized by applying the No-Touch Technique (reference).
Developed to avoid contact between the surgeon’s hands and penile/scrotal skin, this method also seeks to reduce postoperative complications.
Balancing length and girth is important for function and comfort during sexual activity.
Graft-free reconstruction using the Egydio Technique strives to maintain this harmony while respecting nerve limits.

A penile graft is not the most modern option because it can affect both cosmetic and functional results.
Penile reconstruction should therefore be performed by an experienced professional using updated techniques supported by medical literature.
