Medical disclaimer

What the information on this site is, what it is not, and what to do in an emergency. Last updated 27 September 2026.

Disclaimer

Educational information, not medical advice

Short answer

The information on this website is for educational purposes and does not replace an individual medical consultation. Suitability, treatment volume, expected outcome and risk profile vary between patients.

No individual advice
Nothing on this site is a diagnosis or a treatment recommendation for you. Messages exchanged with the patient coordination team are practical information, not a medical consultation.
Results vary
Published figures describe groups of patients in specific studies. Clinic-reported figures describe the clinic’s own caseload, are not the result of a trial and are not guaranteed. Your result depends on your anatomy, baseline circumference, filler distribution, treatment volume and physician assessment.
Off-label use
Teosyal Ultra Deep, the filler used by the clinic, is approved for facial indications. Its use in the penis is off-label, meaning it is used outside the indications listed by the manufacturer, on the responsibility of the treating physician. This is discussed at consultation.
Risks
Penile filler carries risks, including swelling, bruising, lumps, asymmetry, migration, infection and, rarely, vascular complications. These are described in the risks and safety guide.
Evidence
The published evidence on penile filler is limited and much of it is of low quality. Where a source is a conference abstract rather than a full journal article, it is identified as such.
Photographs
This site publishes no patient before-and-after photographs. Photographs on the site show the physician and the clinic premises.

Urgent care

If you need urgent medical help

In an emergency, call your local emergency number or go to the nearest emergency department. Do not wait for a reply from the clinic.

After penile filler, seek urgent care for severe or increasing pain, skin that turns pale, dusky, blue or black, rapidly spreading redness or swelling, fever, or difficulty passing urine. Then contact the clinic on the number you were given at discharge, and tell any doctor who treats you that you have had hyaluronic acid filler.
