Men considering medical options to improve penile size are often deciding between penis enlargement surgery and penis filler injections. While both treatments aim to improve confidence and appearance, they work in very different ways and deliver different outcomes.
This article explains the key differences to help you make an informed decision.
Penis enlargement surgery is designed to create a permanent structural change.
The most common surgical techniques include:
Ligament release surgery to increase flaccid length
Fat transfer to permanently increase girth
Ligament release surgery increases flaccid length, with erect length increases usually modest or minimal. Fat transfer increases girth permanently by using the patient’s own fat.
Surgery is performed under general anaesthetic and requires a structured recovery period.

Penis fillers use hyaluronic acid injections to increase penile girth.
Key points:
No surgery
Minimal downtime
Temporary results (typically 12–24 months)
No significant increase in erect length
Some men notice improved flaccid hang due to reduced retraction, but fillers do not alter internal erectile structures.

Many men choose surgery for long-term change, while others prefer fillers as a non-surgical option. A consultation with an experienced urologist is essential.
There is no “one size fits all” solution. The best approach depends on anatomy, goals, and expectations. Medical guidance is critical to achieving safe and realistic outcomes.
