How Long Does Penis Enlargement Surgery Last?

Penis enlargement surgery has become increasingly popular in the UK, but one of the most common questions patients ask is: how long do the results actually last?

At Moorgate Andrology, our Urologists perform both penis girth enhancement (usually via fat transfer) and penis length surgery (suspensory ligament release). Each part of the procedure has a different expected longevity — so let’s break it down clearly.

🔹 How Long Does Penis Girth Enlargement Last? (Fat Transfer)

Penis girth enlargement using autologous fat transfer is considered permanent, with the important note that:

• 30–50% of fat may be naturally reabsorbed in the first 3 months

• After this period, the remaining fat is the fat that stays long-term.

🔹 How Long Does Penis Length Surgery Last?

Suspensory ligament release is a permanent anatomical change.
However, the amount of visible erect length gained is usually marginal — something we always discuss honestly with patients.

To maintain the length gained in the flaccid state, patients must:

• Use a penis traction device for approximately 6 months to 1 year

• Follow Urologist-led instructions carefully

This ensures the ligament heals in a lengthened position.

🔹 How Long Do Penis Enlargement Fillers Last?

If you are comparing surgery with fillers:

• Hyaluronic acid penis fillers generally last 12–24 months

• They gradually break down and are fully reversible

• Semi-permanent fillers (PLLA/PMMA) should be avoided due to risk of hard lumps

🔹 Will I Need More Than One Procedure?

Most patients undergoing girth surgery choose to have:

• One main procedure, then

• One top-up session to increase volume some years later

Length surgery is  one operation only, provided traction is performed correctly.

🔹 What Affects Longevity of Results?

• Smoking (slows healing and reduces fat survival)

• Weight fluctuations

• Poor compliance with traction

• Chronic illnesses like diabetes

• Choosing a non-specialist provider

Choosing a Urologist-led team significantly improves outcomes and safety.

The Bottom Line

Penis enlargement surgery can provide long-term and often permanent results, particularly for girth enhancement. Length gains in the flaccid state are also permanent, provided the traction protocol is followed.

For the best, safest and most natural results, always choose a Urologist-led specialist centre.
