At UroFill®, we believe enhancement is about confidence, not competition. We help men across the globe take control of their sexual wellness through medically guided penile girth enhancement. The goal? The penis you want — not someone else’s idea of perfection.
This page will help you:
- Understand how many units (mL) of hyaluronic acid may be needed to achieve your desired girth size
- Learn how to properly measure your penis
- Set realistic expectations
- Avoid common pitfalls from over-enhancement
- Discover why gradual, professional care is the best path forward
What Is a “Unit” of UroFill?
Each UroFill® treatment unit is measured as one 1.2 mL syringe of hyaluronic acid-based filler.
- Minimum starting treatment: 4 to 6 units
- Single-visit maximum: Up to 6 units per visit
- Maximal enhancement: dependent on size of phallus and tissue capacity
Your UroFill® certified provider will work with you to determine the right number of units based on your current penile size and enhancement goals.
On average, men see a girth increase of 0.25 to 0.5 inches per session.
🌐What Do Most Men Choose?
While some men aim for dramatic change, most are happiest in the 15 to 25 unit range. This range typically offers a noticeable yet natural enhancement that maintains sexual comfort and function.
📈 National Average UroFill® treatment: 17.2 units
This range balances aesthetic satisfaction, anatomical safety, and patient-reported confidence.

📖 Why Gradual is Better
Think of UroFill like body sculpting: you wouldn’t expect perfect abs from one gym session, and penile enhancement is no different. Our philosophy emphasizes gradual, staged treatment that works with your anatomy and minimizes risk.
- Improves confidence without risking irregularity
- Preserves sensation and natural function
- Respects tissue elasticity and long-term safety
We’ve seen it all — from guys asking for double injections on day one to those chasing an unrealistic ideal. Our job? To say no when needed, and guide you toward safe, aesthetic outcomes.
💪 How Big Is Too Big?
Let’s be real — size matters. But so do balance and pleasure. There is such a thing as too big, and going beyond 6.5″ in girth may create:
- Pain or discomfort during intercourse
- Loss of sensation
- Irregularities or rippling
- Partner dissatisfaction
Your penis isn’t a sex toy — it’s a functional, living part of your body. Treat it with care.
UroFill® is not about creating the world’s biggest penis. It’s about helping you build the confidence that comes from loving what you see in the mirror and knowing you’re enhancing your body on your terms.
🫠 The Psychology of Enhancement
Some men may experience penile dysmorphia — an obsessive dissatisfaction with size despite noticeable gains. At UroFill, we help patients stay grounded:
- Realistic expectations
- Clinical evaluations
- Compassionate care
Enhancement should build your self-esteem, not become your identity.
🪖 Professional, Medical-Grade Results
Every UroFill procedure is:
- Performed by a certified urologist or trained provider
- Backed by science and patented technique
- Conducted in a sterile, medical environment
We never use cannulae or “permanent” fillers like silicone or PMMA. These materials are dangerous and often cause disfigurement. UroFill® is a safe, reversible, hyaluronic acid-based alternative.
