Why Fill in Istanbul

Where Clinical Precision
Meets Istanbul Excellence

Every detail of your experience — from the filler we use to the room you sleep in — is chosen for quality, safety, and discretion.

01

Premium Teosyal Filler

We exclusively use Teosyal by Teoxane Laboratories (Geneva, Switzerland) — CE-certified, clinically validated HA filler with over two decades of safety data. Not a generic product. The same formulation used by elite aesthetic clinics across Europe.

02

Blunt Cannula Technique

Our specialist performs girth enhancement using a blunt-tipped cannula — not a sharp needle. This technique reduces bruising, eliminates vascular injury risk, and produces smoother, more even distribution. A single entry point. Superior results.

03

Fully Reversible

Hyaluronic acid can be completely dissolved with hyaluronidase within 48 hours. This reversibility — unavailable with surgical or permanent alternatives — is one of the primary reasons HA filler is the international clinical standard for non-surgical penile girth enhancement.

04

Expert Physician — 10+ Years

Prof. Dr. Zülfü Sertkaya brings over a decade of dedicated specialisation in male aesthetic medicine. Every procedure is personally performed — never delegated. Pre-procedure assessment, injection architecture, and post-procedure evaluation are all his direct responsibility.

05

All-Inclusive Packages

From airport pickup to hotel check-out, we coordinate every detail of your Istanbul stay. Treatment packages include 4 or 5-star accommodation, private transfers, curated dining experiences, and optional Bosphorus yacht tours. You arrive — we manage everything.

06

Complete Discretion

All patient records are maintained under strict medical confidentiality. We do not share patient imagery without explicit written consent. Communication is through secure, private channels. 70% of our patients travel internationally — we understand that privacy is not optional.

The Procedure

How Your Treatment
Journey Works

A structured, unhurried experience — from your first online consultation to the day you fly home with visible results.

01

Online Consultation

Before you travel, complete a private consultation with Prof. Dr. Sertkaya's clinical team. We review your medical history, discuss your goals, recommend the appropriate filler volume, and confirm the procedure is suitable for you. No commitment required.

02

Arrival & Welcome

Our team meets you at Istanbul Airport with a private transfer to your hotel. Depending on your package, you'll be staying at a 4-star comfort hotel or one of the city's premier Bosphorus-view properties. Check-in, settle in — the city is yours.

03

Procedure Day

Topical anaesthetic is applied 20–30 minutes before the injection, ensuring comfort throughout. Using a blunt cannula, Prof. Dr. Sertkaya injects Teosyal HA filler into precise tissue planes along the penile shaft. Total appointment: 60–90 minutes. Results visible immediately.

04

Recovery & Istanbul

Most patients return to light activity within 24 hours. While you recover in your hotel, Istanbul is at your doorstep — Bosphorus views, world-class restaurants, and centuries of history. Sexual activity is advised to resume after 7–10 days.

05

Return Home

Most international patients depart 24–48 hours after the procedure. You leave Istanbul with visible results, a written aftercare protocol, and 30-day WhatsApp support from our clinical team. Final settled results appear at 2–4 weeks as initial swelling resolves.

💬 WhatsApp Us Directly
How long does the procedure take?
+

The complete appointment — including pre-procedure preparation, topical anaesthetic application, the injection, and post-procedure assessment — takes 60 to 90 minutes. The injection itself lasts 20–30 minutes. You return to your hotel the same day.

Is the procedure painful?
+

No. Topical anaesthetic cream is applied 20–30 minutes before injection, providing effective surface numbing. Most patients describe the sensation as pressure rather than pain. For patients with a lower pain threshold, a local anaesthetic block can be used at Prof. Dr. Sertkaya's discretion.

How much girth increase can I expect?
+

Clinical studies report a mean flaccid girth increase of 2 to 2.5 cm (approximately 0.8 to 1 inch) following 15 ml of HA filler. Larger volumes — up to 22 ml in our Exclusive Package — produce proportionally greater augmentation. Individual results depend on baseline anatomy and tissue elasticity.

How long do results last?
+

Results last 12 to 24 months on average. Teosyal — due to its high molecular weight and cross-linking density — tends to last toward the upper end of this range. As the filler gradually metabolises, girth slowly returns toward baseline. Many patients choose annual top-up sessions to maintain results.

Does it affect erection quality?
+

No. Filler is placed in subcutaneous tissue only — not in the erectile bodies (corpora cavernosa). Blood flow, erection mechanism, and neurological function are entirely unaffected. Multiple clinical studies report no significant change in erection quality. PRP therapy (P-Shot), available as an add-on, has documented evidence of improving erection quality.

Is the procedure fully reversible?
+

Yes — completely. Hyaluronidase, an enzyme available at our clinic, dissolves hyaluronic acid rapidly and completely. An injection of hyaluronidase into the treated area returns the tissue to its pre-procedure state within 24–48 hours. Reversal is available at no additional charge in the event of any complication requiring it.

How soon can I travel after the procedure?
+

Most international patients depart Istanbul 24–48 hours after the procedure. Flying is not contraindicated — the filler is not affected by altitude or cabin pressure. We recommend avoiding tight clothing for the first 24 hours. Same-day departure is possible in most cases, though we prefer patients to stay at least one night for observation.

What are the possible complications?
+

Published clinical data report: asymmetry (6.1%, managed with additional filler top-up), filler migration (7.7%, managed with hyaluronidase), minor nodules (4.6%, managed with hyaluronidase), and infection (1.5%, managed with oral antibiotics). No serious adverse events (vascular occlusion, permanent tissue damage) have been recorded in peer-reviewed series using the cannula technique.
