Written by David Mills | Dec 23, 2025 8:02:26 AM

Penis enlargement surgery and injectable fillers are often discussed as if they are interchangeable. In reality, they are very different treatments, suited to different goals, anatomies, and expectations.

This article explains the key differences between penis enlargement surgery and fillers, helping you understand which option may be appropriate for you.

What Is Penis Enlargement Surgery?

Penis enlargement surgery is a permanent surgical solution that may involve:

  • Suspensory ligament release (to improve flaccid length)

  • Fat transfer (to increase girth)

Surgery is performed by a Specialist Urologist and is tailored to individual anatomy.

What Are Penis Fillers?

Penis fillers involve injecting hyaluronic acid into the shaft to increase girth.

Key points:

  • Non-surgical

  • Performed under local anaesthetic

  • Temporary (typically 12–24 months)

Comparing Surgery vs Fillers

Permanence

  • Surgery: Permanent

  • Fillers: Temporary

Length Change

  • Surgery: Flaccid length increase (erect increase is marginal)

  • Fillers: No length increase

Girth Change

  • Surgery: Permanent increase via fat transfer

  • Fillers: Temporary girth increase

Downtime

  • Surgery: Several weeks

  • Fillers: Minimal

Who Is Best Suited to Surgery?

Surgery may be suitable for men who:

  • Have significant retraction

  • Want permanent change

  • Are comfortable with recovery time

  • Want a one-off solution

Who Is Best Suited to Fillers?

Fillers may suit men who:

  • Want to “trial” girth enhancement

  • Prefer non-surgical options

  • Are unsure about permanent change

Which Option Is Better?

There is no single “best” option — only the right option for the individual.

A consultation with a Specialist Urologist is essential to determine suitability.
