Procedure
Hyaluronic acid filler
A minimally invasive option with adjustable volume.
01 What it is
Injection of cross-linked hyaluronic acid into the soft tissue under the penile skin to increase circumference.
02 What it aims to change
Primarily flaccid and erect girth. It does not lengthen the penis and does not change erectile function.
03 How it is performed
After topical or local anaesthesia, filler is injected in the layer beneath the skin along the shaft and shaped by hand. Volume is chosen with the patient.
04 What published studies report
Short- and mid-term studies and case series report measurable girth increase and generally high early satisfaction. Follow-up is often limited and comparators are frequently absent.
05 What remains uncertain
How long the effect lasts varies by product and volume. Long-term comparative evidence against other methods is insufficient, and repeat-injection behaviour is not well characterised.
06 Common short-term effects
- Swelling
- Bruising
- Temporary tenderness
- A feeling of firmness
07 Potential complications
- Nodules or lumps
- Asymmetry
- Migration of material
- Irregular contour
- Infection
- Rarely, vascular compromise
08 Reversibility and revision
HA can often be partially or fully dissolved with hyaluronidase, which makes it comparatively adjustable. Revision may involve dissolution, massage, or re-injection.
09 Recovery
Most daily activity resumes within a short period; sexual activity is typically deferred for a clinician-defined interval. Outcomes vary.
10 Questions to ask
- What product is used, and how much volume?
- What is the expected duration?
- Can it be dissolved if I am unhappy?
- How are nodules managed?

Girth techniques can increase circumference short term, but durability and complication data (nodules, asymmetry, reabsorption) limit strong conclusions.
