The Non-Surgical Penis Enlargement Approach

  • Instant results with less downtime (patients can resume normal activities after 7 days, heavy activities after 1 week)
  • Cheaper option than surgery, and considerably less invasive
  • Increase flaccid and erect thickness (girth) at the same time
  • Dermal filler selected for maximum aesthetic and functional result
  • GMC registered Plastic Surgeon
  • Safer and reversible, if necessary, using Hyaluronidase

Studies in peer-reviewed medical journals are referred to in the Medical Studies section, available here

The most relevant and comprehensive study comparing lipofilling (surgical fat transfer method) and Macrolane branded Hyaluronic acid is the 2013 study found in the reviews section “Use of Macrolane VRF 30 [Hyaluronic Acid] in emicircumferential penis enlargement.”

The authors retrospectively reviewed the results of 83 patients who underwent penis enlargement with either their HA-injection technique or lipofilling between December 2007 and July 2011. Safety, efficacy, and patient satisfaction were assessed.


The circumferential enlargement obtained from both techniques ranged from 3.2 to 4.5 cm, with a decrement during erection. In all patients, the increase in penis length ranged from 1.8 to 3.6 cm.

No complications were seen in patients treated with HA [Hyaluronic Acid], whereas 8 patients treated with lipofilling [fat grafting, fat injection] developed granuloma, and another experienced fat necrosis.

The vast majority (n = 72) of patients reported being “very satisfied” with the results.


The ideal technique for penis enlargement should be nonsurgical, with a satisfactory and predictable result, a low rate of complications, and long-term stability. Emicircumferential enlargement with HA [Hyaluronic Acid] filler meets these requirements. However, results have been durable but not definitive, and repeated treatment (with associated costs) is necessary.

Penis Lengthening Surgery –  No increase in erect length NHS

The most common technique involves cutting the ligament that attaches the penis to the pubic bone and performing a skin graft at the base of the penis to allow for the extra length. Professor Wylie says the surgery can result in an average gain in length to the flaccid penis of 2cm, but there will be no change to the size of the erect penis.

Furthermore, the erect penis won’t point as high as before the operation because the ligament which was cut no longer offers support.

“A lot of men who have this treatment don’t truly appreciate this loss of angle,” says Professor Wylie. “It can make sex quite uncomfortable. You’ve got to do a lot more manoeuvring with your partner. The advantage of a 2cm gain in flaccid length is far outweighed by the loss of angle of erection.”  UK NHS 2015

“Some surgical techniques to increase penis girth involve injecting fat taken from another part of the body into the penis. Some studies have reported increases in circumference of 1.4-4cm.

However, studies that followed men up over a longer time suggest disappointing results, with complications including disfigurement, scarring, lumpiness and infection. Another method, still in its experimental stage, involves pulling back the skin of the penis to wrap a tube-like biodegradable frame filled with tissue cells around the shaft.

Professor Wylie says the use of biodegradable frames has had better results than fat injection. “The problem with injecting fat is that over time, the body will re-absorb the fat which can result in a return to the penis’ original size,” he says.”  UK NHS 20/04/2015

Surgery to increase penis girth

“Surgery to increase the girth of the penis can involve injecting fat taken from elsewhere in the body into the penis.

There’s a risk that the penis may look uneven or lumpy, and there may be scarring. The injected fat can also disappear over time.

Very little evidence has been published on the long-term effectiveness and risks of this technique.”   UK NHS 04/04/2015

Surgery to increase penis length

“A study in 2006 found that this procedure led to an average increase of 1.3 cm in penis length. However, only 35% of men who had the operation were happy with the results.” [emphasis added] UK NHS 04/04/2015

Fat transfer or lipofilling to the penis.

It may sound like a good idea to make the penis “fatter” by using fat.

However, the penis is not made of fat, to begin with, and is not designed to store fat.

Recent advances in fat injection techniques and filtration methods have improved the survival rate of fat transplanted to the penis.

However, reliably and predictably of the result remains somewhat variable.

The likelihood is that even with the most advanced approaches, you will require further top up procedures (additional surgery).

Hyaluronic acid injection is a tried and tested technique to add volume, using a filler, such as VOLUMA.

Hyaluronic acid is widely used in aesthetic medical circles traditionally as a filler for the lips and face. The main attraction of this treatment is there is no surgery involved, and the treatment takes just minutes. There is also no general anaesthetic required, and there is no downtime, unlike surgery.

The penis is instantly thicker without waiting for results. By using an HA-based filler, patients have the advantage of instant thickening on an out-patient basis.

The results of the VOLUMA thickening treatment typically lasts between 12 and 24 months, with less filler needed on repeat treatments.

You can have repeat treatments for more girth whenever you want, with the knowledge that there is no downtime involved and with instant results.

Unlike fat grafting or fat injections, the filler we use (hyaluronic acid) naturally breaks down over time and can be dissolved quickly in the unlikely event there is any problem, through the use of Hyaluronidase (see video below).

Repeat visits are required, every 1 to 2 years depending on the type of filler used (Ultra vs Voluma), to maintain the penis girth. As some residual filler will remain after 1 – 2 years, the amount of filler required (and cost) is less on subsequent visits.  A typical cost would be just over £1,000 for 3 syringes of filler.

The Androfill HA filler approach involves less risk to the penis, and significantly less downtime than traditional fat transfer methods. Permanent results can mean permanent problems. It may be better to opt for a less invasive, non-permanent and reversible procedure, than accept the risk of permanent penis deformity.

All patients considering cosmetic surgery of any kind should make themselves aware of the risks involved.  Patients should make use of all resources available to them including entering a simple search in their internet browser of phrases such as “complications penis surgery”, etc.

The main issues raised in the article include:

  • Mild to severe absorption with severe deformity,
  • Skin adhesions,
  • Skin scarring
  • Necrosis associated with severe deformity, and severe infections.

What about the permanent PMMA injections to the penis?

PMMA or liquid silicone injections to the penis are not a good idea.

PMMA is a plastic, a polymer derived from oil.

Do you really want a plastic in your penis, permanently?

If something goes wrong, the PMMA is impossible to get out.

Some men travel to have PMMA injected into their penis in Tijuana, Mexico or Rio de Janeiro, Brazil where there is no regulation against its use. We advise strongly against this.

For more information on why PMMA or liquid silicone are not suitable substances to be injecting into one’s penis, please review the articles below.
