About This Procedure
Why Choose Meva Clinic?
A long-lasting surgical girth option using an acellular dermal matrix graft.
A dermal matrix graft is a surgical girth option for men who want an even increase in circumference rather than a filler the body gradually absorbs. The surgeon places a sheet of acellular dermal matrix, donor tissue processed so that cells are removed and a collagen framework remains, around the shaft beneath the skin. In Turkey this is performed under general anaesthesia at a partner hospital, with one hospital night and about six partner-hotel nights according to the confirmed care plan. Desk work usually resumes after 10–14 days; exercise and sexual activity wait for surgeon clearance, typically at 4–6 weeks. Healing, swelling and final contour differ between patients. Every case begins with a confidential online review. A non-surgical alternative is HA filler for girth.

The Clinical Procedure
Under general anaesthesia, the surgeon makes a small incision, usually near the base of the penis or along the circumcision line, creates a plane beneath the penile skin and wraps a measured sheet of acellular dermal matrix around the shaft, fixing it so that it lies evenly. The skin is closed and a compression dressing holds the graft in position. You stay one night at the partner hospital, then recover at the partner hotel with a wound check before you fly home.
Specialist Assessment
Anatomy, medical history and goals are reviewed, together with your suitability for surgery under general anesthesia.
Surgical Planning
Graft size, incision, risks, limitations and aftercare are discussed and agreed before the day of surgery.
Graft Placement
Under general anesthesia, an acellular dermal matrix graft is placed around the shaft beneath the skin.
Hospital Stay & Follow-up
After a one-night hospital stay, wound care and dressings are explained, and healing is checked before you fly home.
Recovery & Transformation Journey
Phase 1: Hospital Night & Dressing
The acellular dermal matrix is placed under general anaesthesia, followed by one night at the partner hospital. A supportive dressing holds the graft in position, and the wound is checked before you move to the partner hotel.
Phase 2: Hotel Stay & Wound Checks
Over about six hotel nights, swelling and bruising are expected and the dressing is managed as instructed. The wound is reviewed again before you fly home.
Phase 3: Swelling Settles
Desk work usually resumes after 10–14 days. Swelling and early firmness ease gradually as your own tissue incorporates the graft. Avoid pressure, strenuous exercise and any sexual activity.
Phase 4: Surgeon Clearance
Exercise and sexual activity resume only after surgeon clearance, typically at 4–6 weeks. The final contour and feel develop over the following months and are reviewed through remote follow-up.
The Meva Advantage
One surgical session for an even, long-lasting girth increase, planned and performed by a partner specialist at an accredited hospital, with honest expectations from the first message (around 1 cm average gain in published series) and one coordinator through to remote follow-up at 12 months.
Medical Guidelines & Safety Protocols
Hospital-based procedures are coordinated through accredited partner hospitals, including JCI-accredited institutions where clinically appropriate. Below are the clinical guidelines, safety protocols, and medical reference documentation for this procedure.
Indicated / Suitable For
- Men seeking a single surgical girth procedure rather than repeated filler sessions
- Men in good general health who are fit for general anaesthesia and a one-night hospital stay
- Non-smokers, or men who will stop smoking around surgery, since healing of the penile skin depends on good blood supply
- Patients able to stay about a week in Istanbul and follow strict wound care and abstinence until surgeon clearance
- Men who understand that early swelling and firmness are expected and that the final feel develops over months
Contraindications / Not Suitable
- Body dysmorphic disorder or size anxiety with normal penile dimensions, where counselling comes first
- Smoking that cannot be stopped, or uncontrolled diabetes, which raise the risk of delayed healing and skin breakdown
- Active genital infection, penile skin disease, or extensive scarring from previous penile surgery until reviewed by a specialist
- Previous silicone, paraffin or other permanent injections into the shaft
- Bleeding disorders or anticoagulant medication that cannot be safely paused before general anaesthesia
Pre-Operative Evaluation & Diagnostic Checks
Andrological Examination: Girth and length measurement, assessment of penile skin and any previous scars, and planning of graft size and incision.
Erectile Function Review: Questionnaire-based assessment, since comfort during erections after grafting is part of counselling.
Laboratory Profile: Blood count, coagulation profile, blood glucose or HbA1c and infection screening before general anaesthesia.
Anaesthesia Consultation: In-hospital review of medical history and fitness for general anaesthesia.
Expectation & Psychological Assessment: Discussion of the realistic girth change and screening for body dysmorphic concerns.
Potential Risks & Complications
In compliance with transparent clinical reporting, Meva Clinic ensures patients are fully informed of the physiological risks associated with surgical procedures through accredited partner-hospital safety protocols where clinically appropriate.
Marked swelling of the shaft and foreskin is expected in the first weeks; managed with the supportive dressing, elevation and rest.
Blood can collect beneath the skin; careful control of bleeding and the compression dressing reduce this, and drainage is arranged if needed.
The skin over the graft can heal slowly or, less commonly, break down; not smoking, avoiding pressure and early wound checks help, with dressings or surgical care when required.
Infection is treated with antibiotics; if it does not settle, or the graft becomes exposed, removal of the graft may be necessary.
A feeling of tightness during erections and early firmness are commonly reported and usually ease as the graft is incorporated.
The increase can be smaller than hoped or irregular; published series report modest gains, which are discussed openly before surgery.
Realistic Expectations & Outcomes
A dermal matrix graft can give an even, long-lasting increase in girth, but the change is moderate and it does not lengthen the penis or improve erections. The shaft looks larger in the first weeks because of swelling and the dressing. As swelling settles and your own tissue grows into the collagen framework, some firmness and a feeling of tightness during erections are common and gradually ease. Published clinical series report an average girth gain of around one centimetre, and a recent meta-analysis rated the certainty of evidence for permanent augmentation materials as very low. The final contour and feel develop over several months and are judged once healing is complete.
Revision & Follow-Up Policy
Wound checks take place at the partner hospital and during your hotel stay before you fly home, followed by remote reviews, typically at 1, 3, 6 and 12 months. Early problems such as delayed healing or infection are managed without delay in coordination with the surgeon. Concerns about contour or feel are assessed only after the graft has been incorporated and swelling has resolved, and any further procedure is decided individually by the surgeon on medical criteria. For 12 months after your treatment you can also send photos to the medical team whenever you wish and receive their feedback, and your questions are answered remotely.
