Is penile girth enhancement safe? The risks in the right context

What do the professional societies say about safety?

They describe hyaluronic acid as relatively safe, and stress an assessment before treatment. The International Consultation on Sexual Medicine (ICSM 2024) states that hyaluronic acid "is considered relatively safe," and that follow-up treatments are likely to be needed¹. The Sexual Medicine Society of North America (SMSNA) recommends a proper assessment before any cosmetic enlargement procedure, and opposes permanent materials⁶. The European Association of Urology recommends a consultation and evaluation before treatment, and advises against filler injections for a man with body dysmorphic disorder¹⁰.

In a recent meta-analysis comparing enlargement methods, hyaluronic acid had the lowest complication rate of the methods studied. The comparison is indirect, because no single trial has compared all the methods head to head¹¹.

What is the difference between a common risk and a serious one?

Most of what happens after treatment is bothersome, but not dangerous.

• Common and mild: swelling, tenderness, a small bruise, a lump you can feel under the skin, and uneven distribution. In a series of 230 patients, the reported complications were bruising, lumps and infection; all were treated and none left lasting damage².
• Uncommon: migration of the material to the base of the penis or the foreskin, and prolonged swelling of the foreskin².
• Rare and serious: severe infection, and compromised blood flow to the skin. Such conditions are described in the literature and require prompt treatment³⁷.

The signs that mean you should seek care immediately are listed on the complications and lumps after penile injection page, and what is normal in the first days on the swelling after penile girth enhancement page.

What raises the risk more than anything else?

The material, who injects it, and the amount. In a series of men who had a foreign substance injected into the penis, such as silicone, paraffin or oils, the complications were severe and sometimes appeared years after the injection⁴. Penile paraffinoma is described as a condition that sometimes requires reconstructive surgery⁵. A urological review of complications of enlargement procedures stresses that injection without a proper method and in large amounts carries more complications and poorer results³.

The FDA adds two warnings that are relevant here too: do not buy fillers online, and do not use needle-free injection devices, which are not approved for injecting fillers¹².

Personal factors worth checking before treatment

Part of the risk depends on your health.

• Diabetes, heart disease and smoking, which affect healing and blood flow. See penile girth enhancement with diabetes and other conditions.
• Blood thinners, which increase bruising. Do not stop them without consulting the doctor who prescribed them¹³.
• An active infection or skin disease in the area, which requires postponing treatment.
• Excess foreskin, which has been described as a factor that may increase swelling and migration². See girth enhancement for uncircumcised men.
• Erectile difficulties, curvature or pain during erection, which are worth evaluating first. See penile girth enhancement and erectile difficulties.

Why is reversibility part of safety?

Because it allows a quick correction when something is not right. Hyaluronic acid is broken down by the enzyme hyaluronidase. In aesthetic medicine the enzyme is used to treat lumps, asymmetry and some filler complications⁸, and in penile girth enhancement it has been used successfully to correct asymmetry and treat side effects⁹.

This is a clear advantage over permanent materials, PLA or implants, where correction usually means surgery. However, the enzyme is not a magic solution: it requires a correct diagnosis, and part of what is known about it comes from facial injections rather than penile girth enhancement. Details on the reversibility: how the enzyme works page.

Psychological safety: when will treatment not help?

When the real problem is not size. Most men who seek enlargement are within the normal range¹⁴. For some, the worry is so great that it affects daily functioning even when the measurement is normal, and this may indicate body dysmorphic disorder¹⁵. A 2026 review proposes an assessment framework that examines psychological state before any request for cosmetic enlargement¹⁶.

In such a situation, aesthetic treatment usually does not relieve the distress, which is why the societies recommend an evaluation first¹⁰. This is not a "rejection," but part of the same question: will the treatment do you good. Data on the topic are on the average penis size page.

What can be done to reduce the risk?

A short list that covers most of the risks.

• A physician only, who explains what will be injected and what is done if a complication develops.
• A recognized hyaluronic acid, in its original packaging, with the product name and amount recorded. Details on the which material is injected and how much page.
• A consultation and measurement beforehand, and a review of medications and medical conditions.
• A gradual approach, not a large amount all at once.
• Careful adherence to the instructions in the days afterwards. See preparing for penile girth enhancement.
• Available follow-up, and a way to get in touch if something feels unusual.

Detailed questions and red flags are on the how to choose a safe doctor page.

How is it done at Dr. Dana Buchbut's clinic?

Safety starts with the consultation. Before any treatment, your health, medications and goal are reviewed, measurements are taken, and the risks and what is done if they occur are explained. Treatment is done with hyaluronic acid, using a gradual approach, and the option of breaking down the material with an enzyme is available at the clinic, by medical decision. After treatment you receive written instructions and a way to get in touch. The first contact can be made on WhatsApp, with full discretion.
