Androfill has performing penis filler procedures safely and with great results for a number of years.

By injecting deeper, our proprietary method has less recovery time (7 days) and gives a smoother and firmer result than available elsewhere.

The Androfill technique was presented at the Royal Society of Medicine in London in October 2018.

The full procedure can be viewed here

Content Warning

Androfill penis enlargement injections using Hyaluronic acid filler allow patients to safely and effectively increase the girth of the penis with little downtime.

The process also increases the flaccid length of the penis (but not the erect length).

The weight of the filler and a scaffolding effect reduce penile retraction after losing an erection (meaning less shrinkage from erect to flaccid).

The Androfill penis filler injection technique was invented by Androfill lead surgeon Dr Gary Horn in 2010.

What are the main differences between the fillers?

Standard & Voluma Filler

(Hyaluronic Based Fillers)

  • Safe (Low Risk)

  • Natural substance made by the body

  • 15 years use in the penis (South Korea since 2002)

  • Reversible (safety aspect)

  • Able to be dissolved (Hyaluronidase)

  • Alterable after final result

  • Low complication rate

  • Can be used in Glans Penis (Penis Head)

  • Smooth (with Androfill technique)

  • Firm (with Androfill technique)

  • Lasts 18 months (on average)

  • Budget £1,000 – £1,500 per year

  • Different filler brands give widely varying results

  • Main complications: Infection (low risk when taken with antibiotics)

Hyaluronic acid fillers are safe and effective for penis augmentation.

Ellanse Filler

(Biodegradeable Polyester / PCL Plastic)

  • Less Safe (High Risk)

  • Artificial Substance (Polyester / PCL / Plastic)

  • Used 2 years in penis (since 2016)

  • Irreversible (any complication can remain for 4 years, or more)

  • Non-dissoluble

  • Not-alterable (substance remains for 4 years)

  • High complication rate (granuloma / hard lump in penis)

  • Can’t be used in Glans Penis (Penis Head)

  • Smooth (with Androfill technique)

  • Firm (with Androfill technique)

  • Can last for 4 years

  • Less expensive per year (if no complications occur)

  • Main Complications: Granuloma (painful hard lump or lumps forming in the penis), infection, other tissue reactions

    Treating a complication caused by Ellanse can be expensive, invasive and cause permanent penis damage.

    Due to the complications with Ellanse, Dr Horn prefers to use Hyaluronic acid fillers in the penis.


How long does it last?

With Hyaluronic acid (the safest option), patients will generally lose around 50% of the filler in 12-18 months.

Patients will need to repeat the treatment again, usually with less filler, to maintain their increased size.

Repeat patients benefit from significantly lower prices.

As a rough guide, be prepared to budget around £1,000 – £1,500 per year to maintain a modest increase in penis girth.

With Ellanse filler (a higher risk option), patients will generally lose about 50% of the filler in 2-4 years.

*Individual results will vary from patient to patient.

How much bigger will I get?

After the first procedure, most patients increase their penis thickness by 10-15%.

The more filler used, the thicker the penis will become.

A longer penis (erect) will generally require more filler than a shorter penis.

Click the button below for a page which contains estimates of the amount of filler required according to penis length.

*Individual results will vary from patient to patient.

No more than 10ml of filler should be injected in one session.

Injecting more than 10ml of filler in one session is inadvisable.

Estimate Size Gain – Filler

Hyaluronic acid is a safe and naturally occurring substance that has been used in the face and the body for over 20 years.

The procedure takes less than 30 minutes and is performed by GMC registered penoplasty surgeon Dr Gary Horn.

The simplicity of the procedure opens up penis enlargement to a range of men who would not previously have considered it or are put off by the idea of invasive surgery.

Consultations with the doctor are available in Harley Street, London, Liverpool, Manchester, Norwich and Brussels.

Below is a recording of an Androfill procedure (6 ml of filler).

The patient has applied a topical anaesthetic (numbing cream) and is awake during the procedure and experiences little to no pain.

Presentation of the Androfill Technique

Presentation at the International Association of Aesthetic Gynaecology and Sexual Wellbeing Congress.

Royal Society of Medicine, London, October 2018

The penis is thickened by the injection of a VOLUMA branded filler formed of Hyaluronic acid.

The procedure provides an immediate increase in penis girth.

Being naturally produced by the body, side effects of hyaluronic acid are very rare, and the procedure is reversible by dissolving the filler into water, in the unlikely event the patient wishes to revert back to their pre-treatment penis size.

Hyaluronic acid-based penis injections have been used safely for over a decade, mainly to fill in facial wrinkles and increase the volume of the lips.  The latest generation of fillers are used in non-surgical nose jobs and chin augmentations.

Androfill provides the least invasive medical alternative to traditional penis surgery.

This approach was originally invented in South Korea in 2004, and has been used in the United States since 2012, Australia since 2015, and has been available in the UK from Androfill since 2015.

There are three steps:

1.  A 30-minute consultation with our GMC registered plastic surgeon at our Harley Street, London address.

2.  If the patient wishes to proceed, a topical anaesthetic cream is applied to the penis and the filler is injected.

– With Hyaluronic acid penis enlargement, the penis is instantly thicker.

3.  Abstain from sex and heavy lifting for 1 week.

The patient can have the consultation and the procedure completed within an hour, including the 30 minute consultation time.

A full description of the procedure is available here.

Patient-doctor confidentiality is strictly adhered to.

Due to the quick recovery time, it is your choice whether you wish to inform your partner about the treatment.


Most patients start off with 8 – 10 ml of filler for their first procedure which will thicken an average length penis by around 10-20% in most cases.

(Approximately 0.5 to 0.75-inch increase in penis circumference)

Most patients start off with 8 – 10 ml of filler for their first procedure.

The cost depends on the filler type and amount of filler used.

Most patients should budget for between £2,000 and £3,000 for a first procedure.

Androfill is proprietary, protected by intellectual property, and is not available elsewhere.

Certified Androfill clinics are the only locations to offer the genuine Androfill penis filler technique for girth.

Google search results in 2018 show a clinic claiming to offer the Androfill procedure.

Cannula versus Needle

At Androfill we use either a blunt tip micro-cannula, or, a micro injection needle using the 27g needle supplied in the original by the filler manufacturer.



There are advantages and disadvantages to using both.

At Androfill the penis is injected in the flaccid state only.

Injecting the penis with a medically induced erection (using Prostaglandin) is more likely to cause damage to the engorged penis, and produces inferior results as filler clumps together when the erection is subsequently lost “accordion effect”.

‘Only inject filler when the penis is flaccid’

The results from the Androfill technique can be seen in our Before and After page.

How safe is this procedure?2018-08-10T13:28:14+00:00

This is the safest medical approach available to thicken the penis and considerably safer than surgery.

Complications are rare and usually minor, including temporary swelling and mild bruising.  For more details on risks and possible complications, see here

Infection is a rare possibility. The risk is reduced with a course of antibiotics.

Worldwide, the number of facial aesthetic procedures performed using Hyaluronic acid-based fillers (HA) exceeds 5 million each year.

Complications are exceedingly rare when HA filler is injected by an experienced doctor.


The number of procedures performed using HA to enlarge the penis is lower at approximately 1-2,000 per year in the UK.

How easy is the procedure?2018-08-10T13:28:19+00:00

You could, for example, come in during your lunch hour and have a 30-minute consultation with the doctor.

Then, if you wanted to go ahead, the doctor would give you some numbing cream to apply to the penis.

Then wait 30 minutes; for the penis to go numb.

You then lay back, and the doctor injects the filler into the space between the loose skin onthe penis and the penis shaft.

The injection points from the needle close over in a matter of seconds, or a few minutes at most.

You could go straight back to work if you take it easy, for example, if you work in an office.

However no manual labour or heavy lifting for one week.

– You’re unlikely to experience pain during the procedure, or the recovery.

A video of the complete procedure is shown below. It is possible to complete the procedure with only one incision through the use of a cannula if preferred.

How much more girth will I gain?2018-08-10T13:28:25+00:00

The amount of girth gained depends on the length of the penis and the amount of filler injected.

We recommend an initial treatment of 10-15 vials of the filler for a 2 to 3 cm (~1 inch) increase in penis circumference (thickness).

A shorter penis will require less filler, and therefore less cost. Conversely, a longer penis will require more filler.

Individual results do vary from patient to patient and results can not be accurately predicted.

Some patients will achieve more volume increase from a given amount of filler than others.

An increase of 2 cm to 3 cm is roughly a 20-30% increase in the thickness of the average penis.

This is a substantial gain in penis size and will require some adjustment before any additional increase is contemplated.

The increase in girth can certainly be noticeable during sex, for both you and your partner, and we strongly recommend testing your new girth with any long term partner, before opting for any additional size gains.

Further injections can be provided at a follow-up appointment if additional girth is desired, and patients have flexibility in determining the amount of girth gained, within medically acceptable limits.

In terms of the volume of filler added to the penis, HA is one of the most hygroscopic molecules known in nature, meaning that it absorbs water from the surrounding tissue.

The safest and most effective approach is to add girth cumulatively, in manageable steps and with repeat visits, rather than an ‘all in one go’ approach.

See our Before and After section for typical results.

* Individual results may vary from person to person.

Does the girth procedure require me to visit a hospital?2018-08-10T13:28:33+00:00


This is a non-invasive approach to increasing the girth of the penis, using established techniques from aesthetic medicine.

The procedure itself is completed in less than 30 minutes, with the application of topical anaesthetic cream only.

You will be awake during the procedure which involves the doctor injecting the Hyaluronic acid filler under the skin of the penis around the penis shaft.

Patients are able to leave the clinic directly after the procedure and are free to walk or drive home.

The procedure requires no stitches and leaves only tiny injection points from the filler syringe, which close on their own in a matter of seconds.

Can I drive home after the penis enlargement surgery operation?2018-08-10T13:28:38+00:00


You are able to drive home following the procedure.

Are there any stitches required?2018-08-10T13:28:44+00:00

No stitches are required. Tiny holes are made by the needle in order to inject the filler solution.

How soon after the girth enhancement can I have sex?2018-08-10T12:18:39+00:00

You should not have sexual intercourse for seven days following the procedure.

This ensures that all injection points are completely healed over, in order to reduce any chance of infection.

During the first 3-5 days, the filler is also semi-malleable and will be susceptible to movement should the patient engage in sexual intercourse.

Will my penis will be normal after girth enhancement?2018-08-10T12:18:46+00:00


The penis will function normally in terms of erection and urination. The angle of the erection may be lower due to the increased weight of the penis, and the penis may hang slightly lower when soft (less retraction).  The penis will have more girth or thickness when soft and when hard.

The angle of the erection may be lower due to the increased weight of the penis, and the penis may hang slightly lower when soft (less retraction).  The penis will have more girth or thickness when soft and when hard.

The penis will have more girth or thickness when soft and when hard.

Is it true that the results will be instant?2018-08-10T12:19:38+00:00


Your penis will be instantly thicker following the treatment, due to the filler added to the penis.

You can book in for the treatment on the same day as your consultation with the plastic surgeon and have both the consultation and the treatment completed within the hour.

Will the filler reabsorb after the girth enhancement?2018-08-10T12:19:44+00:00


The filler will slowly reabsorb, usually over 12-18 months (Voluma option).

Eventually, all of the filler will be dissolved.  You may need approximately 1/2 the original amount of filler again in a repeat treatment in 12 months if you wish to maintain your extra penis girth.

*Results may vary from person to person.

How soon after the first girth enhancement will I need a repeat visit?2018-08-10T12:19:52+00:00

Depending on the rate of reabsorption, a repeat will be required within 12-18 months.

If you require 4 syringes of filler, for example, this would cost £1,060 (4 x £265 per ml) at the lower top-up price per ml.

The volume of additional filler required will be lower than in the initial procedure, due to residual filler remaining.

The growth of new tissue is stimulated by the procedure including, through the process of neocollagenesis. However, we do not guarantee a specific level of new tissue gain.

Foreign clinics using Hyaluronic acid for penis girth have reported that up to 50% of the volume of filler injected, will become permanent penis girth gain.

It is important to know, that while very rare, it is possible for the filler to be reabsorbed in only a matter of months. This is not the expected outcome, but it is possible.

Is there any limit to how much HA filler I can have?2018-08-10T12:19:59+00:00

We offer an initial 8-10 syringes of filler, after which additional filler can be added, if desired, after 2 weeks.

This is the safest approach.

It is possible to have more filler, but this must be done cumulatively for the best result, and the highest level of safety.

Ultimately, the girth limit will be determined by the doctor.

Can I see a cosmetic filler injector (doctor, dentist etc) for this to save money?2018-08-10T12:20:05+00:00

It is best not to try to economise with penis enlargement.

You need to see a surgeon who is experienced in penoplasty for this procedure.

Is this penis enlargement technique used anywhere else?2018-08-10T12:20:11+00:00


The technique is available at the North Valley Plastic Surgery in Phoenix, Arizona, USA, and at the Nefretete Klinik in Bonn, Germany and is relatively common in South Korea.

In 2016 Dr Oates of Perth, Australia set up the Calibre Clinic, his website is linked here – Dr Oates

We suggest having the procedure in the UK for reasons of safety and after-care.

Enlarging the girth of the penis through the injection of Hyaluronic acid fillers is steadily replacing surgery due to the relative safety of the procedure versus surgery.

In countries where girth enhancement is more commonplace, such as in South Korea, an injectable filler is now used in over 80% of penile girth enhancement procedures and the percentage is steadily increasing.

Injectable filler enlargement of the penis is now the most popular penis girth procedure in the UK.

Is it abnormal to want a bigger penis?2018-08-10T12:20:16+00:00


You fit squarely within the normal range of men.

If you want a bigger penis you are in the majority – most men would enjoy a larger penis.

Opting to increase penis girth is more normal (some might argue) than:

  • Investing significant time in the gym body-building (steroids and supplements)
  • Spending excessively on luxuries for the ego, such as the cliché of a sports car
  • Just going through life unsatisfied with an important aspect of your body and identity when there is a relatively easy solution.
I have a short penis. Will Androfill do anything for penis length?2018-08-10T12:20:21+00:00

For erect length, no.

For flaccid length, yes, the weight of the filler can cause it to hang lower in the flaccid state.

* Individual results may vary from person to person.

However, as is also the case for ‘penis lengthening surgery‘, there is no increased length in the erect state.


For the majority of men, it is extra length when hard that matters, not more length when soft.

The good news for heterosexual couples is that there is evidence that the majority of women prefer penis girth over penis length.  Penis girth is what is provided by this procedure.

In a University of Texas Study, 90% of partners preferred a wider penis while only 10% preferred a longer penis, a link to the study is here.

A study by UCLA’s Sexual Psychophysiology and Affective Neuroscience (SPAN) Laboratory found that women prefer a larger penis girth for casual sex.

Results of this study, as reported by LiveScience, have not yet been published in a peer-reviewed journal.

What is Hyaluronic acid?2018-08-10T12:18:33+00:00

Hyaluronic acid is a natural ingredient in the skin responsible for retaining moisture and supporting the skin structure. Find more information here

What does Hyaluronic acid look like?2018-08-10T12:18:25+00:00

The solution used in the penis is smooth and firm and will integrate with the surrounding tissue naturally, taking on its warmth and feel to the touch.

Hyaluronic Acid
Why would I go for this non-surgical approach rather than surgery?2018-08-10T12:18:20+00:00

Penile surgery is a higher risk and largely obsolete approach to penis enlargement.

A surgical approach is taking unnecessary risks, with your penis.

For penis thickness, surgery is no longer necessary. 

What about fat transfer or lipofilling to the penis?2018-08-10T12:18:13+00:00

It might 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 fat has a soft fatty texture which is not ideal in the penis.

Is there something permanent I can inject into the penis?2018-08-10T12:18:01+00:00

You can have a permanent result; but, the risks are higher.

It is possible to travel to Tijuana, Mexico or Brazil to have PMMA or silicone injected, where there is no regulation against its use.

However, PMMA is a processed polymer similar to plastic and does not belong in the body. 

It is near impossible to surgically remove PMMA beads from the penis if there is a bad reaction.

The cost of doing so is high financially, as well as causing damage to tissue into which the PPMA has integrated.

Hyaluronic acid, by comparison, can be dissolved away by injecting Hyaluronidase enzyme solution.

What is a normal size for a penis? Should I consider girth enhancement?2018-08-10T12:17:54+00:00

Many men choose to have girth enhancement purely to increase self-confidence or as an ego boost, and may not have a small penis at all.

The majority of our patients have an average penis size.

For those in long-term relationships, consideration should be given to the penis size preference of one’s partner.

Incompatibility in size between male and female sexual organs can be the cause of significant dissatisfaction in sexual relationships.

This may mean that it is inadvisable to proceed with a girth increase (if your partner prefers a smaller or thinner penis for example).

Is ‘Hyaluronic acid’ toxic?2018-08-10T12:17:46+00:00

Hyaluronic acid “HA” is not toxic; this is a naturally occurring in the body, and produced by the body.

HA has been used in facial fillers for a number of years, and in osteoarthritis, where it is an important part of the synovial fluid that cushions the joints.

You could even swallow Hyaluronic acid and it would do no damage to the body, indeed is marketed as an oral supplement for some conditions.

Find more information on HA, see here

Can I do something about the procedure if I don’t like the result?2018-08-10T12:17:37+00:00

Yes, as explained in the section What is Hyaluronic Acid, Hyaluronidase enzyme dissolves the HA filler into water, where it passes safely out of the body. This can be done at any time.

This is one reason why Hyaluronic acid penis enlargement is a safer approach to penis enlargement than other methods.

Put simply, in the unlikely event you wish to return to your normal penis size, you can do so, by either waiting for the filler to naturally dissolve itself or by injecting an enzyme to dissolve it instantly into water.

You would be out of pocket by the amount of the initial procedure, but, more importantly; you would not be stuck with a permanent result that you, or your partner, were unhappy with.

How long will the treatment take?2018-08-10T12:17:27+00:00

The procedure itself takes less than 30 minutes on an out-patient basis, however you should set aside 2 hours in order to have a consultation, apply numbing cream., and ask any additional questions you may have.

You can leave the clinic and walk or drive home straight away.

The philosophy behind Androfill

Put simply; more often than not, men would like to have a larger penis.

The results of a recent YouGov poll have been interpreted as follows: “In Britain, being unhappy with your penis size is now the default situation for young men: more 18-to-24-year-old British men say they would like their penis to be larger (42%).”

As increasing penis thickness has become a safe and simple procedure, there is no reason not to make this procedure more readily available to men.

Aside from making men happier about their penis size, by offering this procedure, we hope to prevent:

  • Unnecessary penopasty surgery. Read the NHS position on penoplasty here
  • Risk and costs involved in the consumption of penis enlargement pills
  • Wasted time, cost, and effort involved in the use of penis traction devices, and penis exercise regimes.

Androfill Hyaluronic acid penis enlargement provides:

  • Self-confidence, particularly for men with small or thin penises, but also to normally sized men, who simply wish to be a little thicker below
  • For many, an improvement in the quality of relationships, including the quality of  sex, in some cases
  • A simple ego boost
  • Relief from the anxiety felt by many males, due to their penis size.

The desire for men to want a larger penis is not dissimilar from the desire for a larger body, which drives bodybuilders to bulk up at the gym. Unlike the hours spent at the gym, the addition of the filler makes the penis immediately thicker.
