Penis Enlargement using Hyaluronic Acid (HA)


The use of Hyaluronic Acid Injecton in Penis Enlargement


Studies have been undertaken since 2002 in order to determine the suitability of injectable Hyaluronic acid gel for penile girth enhancement.  In relation to the use of Hyaluronic acid in the face, studies go back to the 1980s and show the substance to be safe and effective.

Hyaluronic acid based filler was an effective technique to enhance penis size with no inflammatory signs or serious adverse reactions in all participants.

Introduction. Despite the debates on penile girth enhancement (PGE), demands for enhancement are increasing. Recently, various fillers have been widely used for soft tissue augmentation with proven efficacy and safety.

Aims. To identify the feasibility and efficacy of PGE by injection of filler.

Methods. Fifty patients with subjective small penis who visited Korea University Guro outpatient clinic were enrolled and prospectively followed. Restylane Sub-Q (Q-med, Upssala, Sweden) was injected into the fascial layer of penile body via 21G cannula with “Back & Forth Technique” and homogenized with a roller.

Main Outcome Measures. From April 2006 to February 2008, 50 patients were enrolled and 41 patients were followed until 18 months after PGE. Changes in penile girth at midshaft were measured by tapeline at 1 and 18 months. Patient’s visual estimation of residual volume (Gr 0–4), patient’s satisfaction (Gr 0–4), and any adverse reactions were also evaluated.

Results. Mean injected volume was 20.56 cc (18–22). Compared with basal girth of 7.48 ± 0.35 cm, maximal circumference was significantly increased to 11.41 ± 0.34 cm at 1 month (P < 0.0001) and maintained as 11.26 ± 0.33 cm until 18 months. In patient’s visual estimation, two patients complained the decrease as Gr 3 with focal depression at 1 month. At 18 months, all patients answered as Gr 4 without asymmetry. Patient’s and partner’s satisfaction score was 3.71 ± 0.46 and 3.65 ± 0.48 at 1 month and 3.34 ± 0.53 and 3.38 ± 0.49 at 18 months. There were no inflammatory signs or serious adverse reactions in all cases.

Conclusions. Considering the property of material, methods, and follow-up results of 18 months, PGE using filler is a very effective and safe technique for penile augmentation.

Penis enlargement is increasingly in demand. Methods for penis enlargement can be classified into surgical, nonsurgical (filling), and mechanical. Each method has shown only relatively successful results. A new formulation of injectable, stabilized, hyaluronic acid (HA)-based, nonanimal gel is available that may have applications for this use.


The authors propose a new technique for emicircumferential-injection filling of the penis and assess the safety and efficacy of this procedure compared with lipofilling [fat grafting, fat injection].


The authors retrospectively reviewed the charts 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.

In human glans penis, injecting hyaluronic acid gel into the dermis was not so difficult and the implants showed long-term residence in the patient’s visual estimation and resulted in high satisfaction rate of patients. These results suggest that injectable hyaluronic acid gel is a safe and effective material for soft-tissue augmentation in patients with small glans penis. Long-term efficacy of more than 1 y needs to be demonstrated.

Permanent Girth Gain


Permanent increase in penis thickness stimulated by the injection of Hyaluronic acid filler has also been reported by Senior Korean Urologist Dr Kim Jin Hong.

Dr Kim Hong is a pioneer of the treatment with over 4,000 procedures performed and numerous publications in medical journals on the use of HA in penis enlargement.


“Hyaluronic acid injections increase penis size by adding volume to the penile tissues. It is naturally integrated into the tissue and will undergo isovolumic degradation in the long term, approximately 4% per month.

Note: nothing about your body is “permanent”. Every part changes over time. We define “permanent” as a result that changes very little over a very long period of time.

We define “temporary” as a procedure such as HA which will decrease in volume from 20 ml to about 12.25 ml in one year.

Older and less specialized varieties of HA continued to decrease over the second year, providing a “permanent” gain of about 39% of the original HA volume. About 61% of the gains were “temporary”.

But current varieties of HA specifically for penis enlargement is more durable and serve as a scaffold longer, resulting in creation of permanent new tissue that is about 50% of injected HA volume. It is the most effective ever and is continually being improved.

Many men consider that an acceptable cumulative and “permanent” gain. You never go back to the starting point.”

The popularity of dermal fillers has grown rapidly in recent years because they offer the rejuvenative and enhancing aesthetic improvements previously only achievable with surgery, but at lower cost and with limited-to-no recovery time. According to data from the American Society for Aesthetic Plastic Surgery (ASAPS), more than 1.6 million dermal filler treatments were performed in 2011, making them the second most popular nonsurgical cosmetic procedure performed in the USA after neuromodulators; the latter procedure is frequently performed in concert with dermal filler injections.1

As public awareness and acceptance of dermal fillers grows, so does the size of the market, with an estimated 160 products currently available worldwide from more than 50 companies. Their main indications are the filling of rhytides and folds, and correction of soft tissue loss due to disease or age.2Increasingly, fillers are used for volume replacement and enhancement procedures,3 including cheek and chin augmentation, tear trough correction, nose reshaping, midfacial volumization, lip enhancement, hand rejuvenation, and the correction of facial asymmetry. As the indications and the number of procedures performed increase, the number of complications will likely also increase.

Understanding the different characteristics, capabilities, injection techniques, risks, and limitations of available fillers is essential for injectors to reduce the risk of complications, improve patient outcomes, and care for patients who have experienced adverse events.
