Penile Enlargement
Two doctor-led routes to added girth and better proportion — a non-surgical HA filler, or a permanent silicone sheet implant. Compare both and choose what fits you.
Care led by Dr. ChaiSenior Urologist · Siriraj Medical School
Overview
Structural penile enlargement is about precision, proportion, and complete anatomical safety. Designed for men seeking noticeable girth enhancement, our doctor-led protocols combine high-grade medical materials with senior urological expertise inside a sterile, licensed operating theater. For flexible volume, we utilize biocompatible Hyaluronic Acid (HA)—a natural compound strategically injected (typically 10–15cc) over roughly one hour to draw moisture, expand girth, and deliver a natural feel. This non-surgical option can be performed alongside a circumcision in the same session and remains fully reversible at any time with hyaluronidase.
For men seeking a permanent result without future top-ups, we offer implant-grade medical silicone sheets precisely inserted through a discreet 3–4cm high scrotal incision and secured beneath the skin. Results are visible immediately, though circumcision is a required prerequisite and can be arranged 1–2 months prior if needed. Every procedure is performed under local anesthesia with total discretion, ensuring clean proportions, natural feel, and hospital-grade safety without compromising sensitivity or function.

Two Ways to Enlarge — Compare at a Glance
Most men choose the non-surgical HA filler — reversible, minimally invasive, with little downtime. A permanent surgical silicone implant is also available for those who want it. Here’s how they compare; open either page for the full detail.
| HA fillerNon-surgical | Silicone implantSurgical | |
|---|---|---|
| Approach | In-clinic HA injection | In-clinic minor surgery |
| Girth increase | +1.5cm to +3cm | About +1.9cm |
| Results | Immediate — same day | Immediate — same day |
| Longevity | Up to 2–2.5 years | Permanent |
| Reversible | Yes — dissolved | Yes — removable |
| Downtime | Minimal — about 2 weeks | About 6 weeks |
| Available at | Bangkok, Phuket & Pattaya | Bangkok only |
| Price | From ฿65,000 | ฿160,000 (from ฿200,000) |
| Best for | A flexible, natural result | A permanent surgical result |
An honest note on length: both options add girth and can increase flaccid (non-erect) length and appearance — they do not increase your erect length. Individual results vary and are discussed fully at a private consultation.
Option 1 — HA Filler (Non-Surgical)
Reversible, minimally invasive, little downtime — the route most men choose.
Inside the HA filler procedure
Dr. Chai walks through the filler procedure — FDA-grade hyaluronic acid placed under local numbing in about 30 minutes. No surgery, and reversible if you wish.
- Girth increase:+1.5cm to +3cm
- Lasts up to2–2.5 years (by brand)
- Reversible withhyaluronidase
Circumcised or Uncircumcised?
HA filler works either way. In circumcised men it tends to settle a little more evenly for a slightly more refined result; uncircumcised men can have it too, though the foreskin can occasionally show as minor unevenness. Because filler is easily reversed with hyaluronidase, that's rarely a lasting concern — the one thing to plan for is travel, if you live abroad and can't easily return for an adjustment.
Option 2 — Silicone Implant (Surgical)
A permanent result with no future top-ups — an implant-grade silicone sheet placed beneath the skin, for men who want durability over reversibility.

Frequently Asked Questions
Is enlargement permanent?
It depends on the route. Hyaluronic acid filler is temporary and reversible — it's gradually metabolised and can be dissolved deliberately with hyaluronidase. A silicone sheet implant is permanent and would require surgery to remove. Most men start with filler for exactly that reason.
Does it affect erections or sensation?
Correctly placed filler sits in the tissue beneath the skin and shouldn't affect erectile function or sensation. Poorly placed filler can, which is the argument for having it done by a urologist. If you already have erectile difficulty, treat that first — enlargement won't improve it.
How much difference will it actually make?
Girth responds better than length, and flaccid appearance changes more than erect. Your urologist will give you a realistic figure at consultation based on your anatomy and the volume used — and will tell you if your expectations aren't achievable.
What's the recovery?
Filler is generally same-day with a short abstinence period your surgeon will specify. Surgical procedures need a genuine recovery of up to a week or more. You'll get written aftercare either way.
Can filler injected somewhere else be removed?
Hyaluronic acid can be dissolved. Oil, silicone and paraffin cannot — those require surgical excision of the granuloma, which we perform. Bring any records you have of what was used.
