How to thicken the penis: the two main methods are hyaluronic acid filler and girth surgery.
A common question among men is whether it’s possible to thicken the penis.
The answer is yes; however, the topic should be discussed responsibly so as not to compromise male sexual health.
Another point to consider is that few men truly need to worry about size or width, since there’s a normal range and a very small penis is uncommon.
For those seeking options, there are techniques described in the medical literature that may be considered—always weighing risks and benefits with a specialist.
Methods: how to thicken the penis
Many people look for ways to increase penile girth for aesthetic reasons or self-confidence. Before trying anything, it’s important to understand that size naturally varies among men and many available methods carry risks.
Always seek medical guidance before starting any treatment. Below are the main ways to thicken the penis:
Hyaluronic acid
Hyaluronic acid–based fillers are an option for those researching how to thicken the penis.
This method involves the injection of a gel-like substance that adds volume to penile tissues. It’s a relatively simple, quick procedure with a short recovery time.
During penile girth enhancement with hyaluronic acid, the substance is injected into specific skin layers to increase thickness.
In some cases, an increase can be seen right after the application, but the substance is absorbed by the body over time—usually between six months and two years. Periodic touch-ups are needed to maintain results.
Girth surgeries
Penile girth surgeries are procedures aimed at permanently increasing circumference.
There are different techniques, chosen according to each patient’s needs and conditions. One of the most common is fat grafting (lipo-filling), which transfers fat from another body area to the penis.
Another technique is the placement of dermal matrices or synthetic materials under the penile skin. These materials help increase thickness and are selected based on biocompatibility and the patient’s goals.
Penile prostheses
Penile prostheses do not enlarge the penis. They are indicated for severe erectile dysfunction when medication has not worked.
The device is surgically implanted and, depending on the model, must be inflated or positioned to achieve an erection for intercourse.
Is hyaluronic acid girth filler safe?
Hyaluronic acid filler is considered a safe alternative for thickening because hyaluronic acid occurs naturally in the body and the procedure is non-surgical—factors that reduce allergy and rejection risks.
Side effects can still occur, such as swelling, bruising, or pain at the injection site. Rare but serious issues include lumps on the penis and infections.
Therefore, it’s essential to undergo filler with a qualified professional to reduce risks and optimize distribution.
Also note that while hyaluronic acid can increase penile thickness, it isn’t permanent and requires periodic maintenance.
How is the filler performed?
Before the procedure, the doctor evaluates the patient to determine the amount of hyaluronic acid needed.
Next, the area is cleansed and, if needed, local anesthetic is applied to reduce discomfort.
The filler is injected with a fine needle or cannula. Afterward, the urologist may gently massage the area to help distribute the product.

What’s the recovery time?
Recovery is usually short; most patients resume normal activities in one to two days. Mild swelling, bruising, and sensitivity can persist for a few days.
Avoid intense exercise, sexual activity, and excessive heat during the first week.
Following these instructions helps reduce complications and allows the hyaluronic acid to settle properly.
What results can hyaluronic acid achieve?
There may be an increase in penile girth, which varies with the amount injected and individual characteristics. Results tend to look natural and proportional.
Although the effect is immediate, the body gradually absorbs the product. Results typically last six months to two years, with maintenance sessions as needed.
Who is a candidate?
Hyaluronic acid filler may suit men seeking increased girth for aesthetic or confidence reasons. Most healthy men qualify, but a medical evaluation is required to rule out contraindications.
Those with active infections, bleeding disorders, or allergies to components of hyaluronic acid may not be ideal candidates.
Are girth surgeries safe?
Surgery can offer a permanent increase in penile girth, but—like any operation—it carries risks.
One example is fat grafting (lipo-filling) using the patient’s own fat via liposuction.
While infection and rejection risks may be lower, downsides include fast fat reabsorption and nodule formation.
Despite risks, some patients report cosmetic improvement, but experiences vary. Because safety is closely tied to the surgeon’s expertise, choose an experienced specialist.

And penile prosthesis—does it thicken the penis?
Penile prosthesis is indicated for cases of severe erectile dysfunction. Men in this situation often experience improved erectile quality after implantation.
In some cases it may increase girth, but the device’s goal is to treat erectile dysfunction—not to thicken the penis.

Does the prosthesis type influence girth?
A prosthesis can change penile thickness, but the effect depends greatly on individual anatomy.
Inflatable and malleable models may add girth; only inflatable cylinders expand, which can favor this cosmetic effect.
However, prosthesis choice isn’t based on cosmetic expectations alone.

Does an inflatable prosthesis thicken the penis?
When an inflatable penile prosthesis is activated, the cylinders expand and the penis looks thicker. Many believe it’s the best option for girth.
In practice, if the penis is naturally thin, expansion is limited. A preparatory procedure may be needed to stretch or expand internal tissues.
Does a malleable prosthesis thicken the penis?
A malleable (semirigid) prosthesis can help increase girth, but results depend on anatomy.
Because it doesn’t expand, size is set during surgery. If the penis is very thin, the urologist may stretch tissues to accommodate a thicker device.
Respecting penile biomechanics is essential
Beyond making the penis thicker, the urologist must preserve function—respecting nerve and internal structure limits.
This helps avoid discomfort, pain, and erectile issues.
Tissue expansion with the Egydio Technique
Tissue expansion is performed when the penis is very thin or when girth has been affected by Peyronie’s disease.
This intervention creates space for the prosthesis and is carried out up to the nerve limit. With expansion, the penis tends to appear wider and fuller when erect.
When is the Egydio Technique recommended?
The Egydio Technique was developed by Dr. Paulo Egydio to recover as much length and girth as possible in men with Peyronie’s.
It treats the curvature, preparing the penis for the implant. The goal is to realign the penis and, in some cases, contribute to girth and function within anatomical limits.
