Named sources
Figures from published studies are attributed to the study, with its size and design, and listed with a DOI or PubMed link at the foot of the page. Conference abstracts are identified as abstracts.
Penile Filler Knowledge Centre
Patient education from Hardrock Clinic’s penile filler programme, led by Assoc. Prof. Dr. Zulfu Sertkaya. Each guide names its sources, separates published evidence from the clinic’s own figures, and shows when it was last updated and reviewed.

Treatment
What the procedure is, the material used and how the volume is chosen.
Results
What the published studies report, what the clinic reports, and how long it lasts.
Safety
Documented risks, how complications are managed, and who should not be treated.
Recovery
The days and weeks after treatment, stage by stage.
Cost
Package prices, what they include and what changes the quote.
International patients
Planning a treatment visit to Istanbul from abroad.
Comparisons
Hyaluronic acid against the other ways of adding girth.
FAQs
Short answers to the questions patients send most often.
Standards
How these guides are written
Clinic figures labelled
Where a figure is the clinic’s own — such as its reported girth change per volume — it is labelled as the clinic’s and never presented as a trial result.
Dated and reviewed
Every guide shows when it was published and last updated, and the date of its last medical review by the physician. A guide awaiting review says so.
