What is Girth Enhancement with PhalloFILL®?

PhalloFILL® girth treatments involve a specialized hyaluronic acid-based penile enhancement technique. It is a minimally invasive procedure aimed at increasing the girth size of the penis, offering a non-surgical alternative to traditional phalloplasty. This technique involves a proprietary method of injection of hyaluronic acid, a naturally occurring substance in the body known for its hydrating and volume-adding properties, into the penile tissue.

The procedure is designed to enhance penile circumference, providing patients with a desired aesthetic outcome while minimizing downtime and potential complications associated with surgical interventions. The treatment aims to improve both the physical appearance and the psychological well-being of individuals seeking penile augmentation.

How Much Girth?

Patients can anticipate an average girth increase of 1/4 to 1/3 of an inch per session, with a total enhancement of 1 to 1 1/2 inches or more after multiple sessions, depending on the individual’s goals.

Achieving any desired girth is possible through multiple sessions. It’s worth noting that our most content clients typically undergo 4 to 6 PhalloFILL® sessions. When devising a customized treatment plan, consider the following average measurements:

The typical flaccid penis has a girth of 3.5 to 4 inches, with many men aiming for 5 to 6 inches when flaccid. The average erect penis measures 5.5 inches in length. (PhalloFILL® enhancement does not affect length.)

The average erect penis girth is 5 inches, with many men seeking to attain a girth of 6 inches or more when erect.

On average, 18 to 30 units are administered during a PhalloFILL® enhancement plan across 3 to 6 sessions.

With sufficient sessions, patients can expect an average girth increase of 1 to 1 1/2 inches. For those seeking more significant girth enhancement results, we have injected over 60 syringes during a PhalloFILL® enhancement plan, depending on the patient’s preferences.

One of the unique features of PhalloFILL® is its high level of customization. The technique is tailored to suit the individual anatomy of each patient, ensuring optimal results that blend seamlessly with the natural contours of the penis.

This personalized approach sets PhalloFILL® apart from other penis enlargement procedures that often yield unfavorable aesthetic outcomes.

Furthermore, PhalloFILL® has overcome the challenges that have historically plagued similar techniques. Doctors have struggled to achieve consistent results with previous methods, leaving many patients dissatisfied with their outcomes.

The PhalloFILL® enhancement is safely performed off-label using FDA approved Hyaluronic Acid Dermal Filler. This type of dermal filler has been proven safe and effective for volume improvement since the first FDA clearances in 2004. The proven girth enhancement technique involves a series of 2 or more treatments which take about 30 minutes to perform. There is NO social downtime, patients must simply refrain from sex and self-pleasuring for about a week and wear a compression sleeve as directed. There are no incisions made using the PhalloFILL® approach.


Just as every nose is different, every penis is different. The goal of each patient is different as well. Some men may be less secure with themselves naked, therefore seeking the “locker room look” while other men may want to better satisfy their partner in bed. The beauty of a customized PhalloFILL® enhancement is the ability to determine and achieve the exact desired outcome of each patient. Some patients have the desire for more girth for “showing”, for others it’s more girth around the shaft for sexual stimulation, and still others desire the shape of their penis to be altered. We can even help straighten the appearance of a slightly curved or misshapen penis. What we cannot accomplish with the PhalloFILL® approach is an increase in the erect length of the penis.

Only approved medical pros

The PhalloFILL® enhancement has developed from thousands of successful procedures and a variety of approaches to penile girth enhancement. You can rest assured your provider is trained and in close contact with the originators of PhalloFILL® while determining your customized PhalloFILL® enhancement plan. You will meet with our medical director prior to your treatment which will be performed by a certified and trained PhalloFILL® injector. Trust your penis with only the best in the industry!


The PhalloFILL® enhancement offers semi-permanent results with years of longevity and filler retention. Patients have reported as many as 4-6 years with some level of retention using hyaluronic acid fillers. The favorable aesthetic outcomes known to PhalloFILL® result from unique injection principles and specialized post-treatment care combined with previous developments from top urologists and plastic surgeons throughout the world. Your PhalloFILL® enhancement can be “touched up” at any time as needed. Most touch ups require a fraction of the amount of filler used for the initial PhalloFILL® enhancement.


The average male can achieve an increase of 1 to 1.5 inches or more in flaccid or erect penile girth over a series of injections. There is no limit to how much girth we can provide our patients while maintaining safe, reliable, comfortable, and effective results. The total process from arrival to checkout is about an hour. There are many benefits to the PhalloFILL® enhancement including less shrinkage when cold, anxious, or due to side effects of medications such as ADHD medications. Greater self-confidence is achieved in the locker room, bedroom, when dressed, and throughout the day and increased sexual satisfaction for both the patient and his sexual partner are often reported. Many of our patients refer to the enhancement as “EgoFILL” because it makes such a dramatic change in their confidence.


The PhalloFILL® advanced treatment for penile girth enhancement arose from a collaboration of the world’s leading reconstructive urologists and plastic surgeons, now collectively performing penile girth enhancement procedures for nearly a decade. The PhalloFILL® enhancement uses safe and effective FDA cleared hyaluronic acid dermal fillers that offer patients reliable, lasting and aesthetically pleasing results. Patients have reported “Perfect Results!”.

Frequently Asked Questions

PhalloFILL® is a proven procedure involving a series of dermal filler injections over a span of 2 or more separate sessions to obtain the patients desired penile girth. The dermal filler used to expand the diameter of the penis is similar and therefore cohesive with the existing anatomical tissue in the penis and therefore gives a natural looking girth enhancement.
After careful consultation with the trained and credentialed PhalloFILL® provider, a patient will first be given a local anesthetic around the desired injection area to prevent any discomfort or pain during the procedure. The injector will then perform a series of dermal filler injections, injecting a total volume of 4 to 6 units of filler per session depending on the patient’s anatomy. Additional units may be injected at the providers discretion for larger anatomies. Once injected, patients are fitted for a compression garment to be worn throughout the treatment process. It is important to refrain from sex and self-pleasuring for 7 – 10 days or as determined by the provider based on your individual anatomy.

The patient should expect an overall girth increase of 1/4 to 1/3 of an inch per session, or an average overall enhancement of 1 to 1 1/2 inches or more after multiple sessions depending on the goal of the patient. Any reasonable girth can be achieved with multiple sessions. Keep in mind that our most satisfied clients have received 4 – 6 sessions of PhalloFILL®. It is important to keep the following averages in mind when creating a treatment plan tailored to your specific goals:

– The average flaccid penis is 3.5 – 4 inches in girth. Many men would like to reach 5 – 6 inches flaccid.

– The average erect penis length is 5.5 inches. (We do not change the length with PhalloFILL® enhancement)

– The average girth of an erect penis is 5 inches. Many men would like to achieve 6+ inches of erect girth.

– On average, 18 – 30 units are injected during a PhalloFILL® enhancement plan over the course of 3 – 6 sessions.

With adequate sessions, the average girth increase is 1 to 1 1/2 inches. Depending on the patient’s desires, we have injected over 60 syringes during a PhalloFILL® enhancement plan for TREMENDOUS girth enhancement results!

Hyaluronic Acid (HA) filler can safely be used to increase the size of the glans (head) of the penis, although with less aesthetically appealing results. The glans is tissue rich in vascularity and lymphatic drainage and the treatment in the glans may only last 3 – 4 months. The PhalloFILL® enhancement was developed for increased girth to the shaft of the penis. Hyaluronic acid injections to the glans of the penis are effective for increased size, however patients should not expect the consistent and lasting results as seen on the shaft of the penis.

Our goal is for patients to be happy with their aesthetic results and the longevity of their filler retention. We do not believe the majority of patients will be happy with the results in the glans, where as we can achieve years of longevity in the shaft using the same filler.

No. There is an illusion in some of the before and after photos on our website that there IS an increase in length, but in reality you simply have less “shrinkage” after the PhalloFILL® enhancement therefore you maintain a “fuller length” when flaccid. Research shows that the only safe and effective way to lengthen the penis is with “stretching” or traction using a penile extender device or stretcher such as the Phallosan® which you can use at home. Learn more about Phallosan here.

Phallosan® exerts gentle tension to the penis. A few small studies have reported length increases of a 1/2 inch to nearly 2 inches using devices such as this.

Surgical methods for lengthening the penis such as separation of the suspensory ligament is risky and often ineffective. The surgery can result in complications such as infection, scarring, and loss of sensation or function. Often the ligament reattaches and causes a retraction of the penis from tissue scarring which can cause the length to actually decrease after surgery.

Yes, although the actual procedure is rather painless, there will be moderate bruising and possible swelling around the injection sites that should be completely resolved within two weeks from your treatment. The penis will be wrapped in a compression garment and the patient may return to normal daily activities immediately following the treatment. Patients should NOT engage in any sexual activities including self-pleasuring for about 1 week following each treatment as determined by your provider. Engaging in sexual activity sooner or failure to follow the post-treatment care as directed may result in migration of the dermal filler which can lead to poor aesthetic outcomes and other complications. Patients should note that every penis is different and due to the expansion and retraction of the penis, irregularities may occur initially, especially in the flaccid state. This is normal, and any irregularities can be addressed during subsequent treatments as the filler is layered into place.
During the PhalloFILL® Enhancement, even and symmetrical columns of filler will be laid along the shaft from the base to the head of your penis for an overall increase in girth. The columns can be laid thicker or thinner in different areas if your goal is to correct irregularities in your natural anatomy. Once the filler has been placed, you will be fitted for a compression garment that will be worn to keep the penis extended and the filler in place while the encapsulation and bonding process takes place with your existing collagen and elastin in your natural tissue. Once bonded, the filler remains in place offering durable and natural results. Limited lymphatics in the pocket the filler is placed allows it to last considerably longer than other areas of your body. While Hyaluronic Acid and other fillers bond to your natural tissue, they are not indestructible and can shift over time depending on the care, sexual lifestyle, and metabolism of filler which varies by patient. A significant benefit of PhalloFILL® and the utilization of Hyaluronic Acid filler as opposed to more permanent options such as PMMA or fat transfers is that we can soften and correct or dissolve almost any irregularity that may arise using a dissolving agent rather than surgical removal which is often necessary to correct migration or nodules, and granulomas associated with permanent fillers. With Hyaluronic acid, a simple injection of the enzyme Hyaluronidase can be used to dissolve any unwanted area of filler and touch ups with additional filler can be performed at any time to fill in areas that may have shifted or metabolized over time. Unlike other treatments, PhalloFILL® is highly customizable, and the non-surgical approach involves no downtime with a minimal recovery. It is important that patients remain diligent with the post-treatment care recommendations of their provider which may vary based on their individual anatomy..

Using this technique, patients routinely reported HA dermal filler retention at 3 – 4 years and sometimes longer. To date, no patient has returned with a complete loss of filler. Since initially studying the girth enhancement technique, most patients have reported considerable long-term retention. Any minor loss of filler can be regained at any time with a simple touch-up treatment, which requires a minimal amount of filler compared to the initial treatments where most of the bulking is done. It is important to remember that every human body metabolizes HA filler differently. Follow-up treatments of 4 to 6 units may be necessary every 12 – 18 months depending on the patient’s lifestyle, sex life, and the rate at which their body metabolizes the filler.

The PhalloFILL® enhancement is highly customizable, so it is important to identify and communicate your goals from the beginning with your PhalloFILL® provider to help determine the best package for your individual needs.

During your PhalloFILL® enhancement the filler is layered and sculpted into place for optimal aesthetic results while also blending with your natural tissue. If you notice any abnormalities in shape or asymmetry along the injection plane following your PhalloFILL® treatment do not be alarmed, this will improve as the filler is layered from one session to the next while the desired increase in girth is achieved. Should you want to remove the filler for any reason, a simple solution can be injected that will dissolve the hyaluronic acid or any portion causing a visible irregularity to your dissatisfaction. This is rarely the case, in fact most men add more over time.

After the first treatment, an average of 10% in filler reduction can be expected due to the inflammatory process, however the majority of filler will remain and could last up to 6 years or longer. The proven PhalloFILL® enhancement and the optimal placement of filler allow for minimal absorption and maximum retention while maintaining the aesthetically pleasing results you desire within the limitations of your individual anatomy.

The technique that lead to the development of the PhalloFILL® enhancement leverages a space between two compact layers of connective tissue or fascia. Our enhancement creates a pocket within these layers of fascia that holds the filler. Limited lymphatics and blood flow within this pocket is what allows the filler to last considerably longer than hyaluronic acid filler injections in the face. The face is full of lymphatics and blood flow so the filler often breaks down within 1 year. The same principles apply to the glans or “head” of the penis which due to vascularity will often break down hyaluronic acid filler over the course of several months, whereas the pocket along the shaft allows the same fillers to last for several years.

The number of units administered per treatment is based on the length of your penis.

A single PhalloFILL® treatment of 4-6 units will range between $2,800 – $4,350 adding roughly 1/4 to 1/3 of an inch in additional girth.

A conservative enhancement of 10 units offers discounted pricing and will range between $5,500 – $6,250. The 10 unit package will offer 2 treatments for most men and can add a noticeable 1/2 to 2/3 of an inch in additional girth.

A more substantial enhancement of 20 units offers our most discounted pricing and will range between $9,900 – $10,900. The 20 unit package will offer 3 – 4 treatments for most men adding roughly 1 inch in additional girth.

Pricing may vary based on location. Visit our pricing page for more information on girth enhancement packages and financing.
