Ever since that Forbes story about Olympic ski jumpers allegedly injecting hyaluronic acid into their penises hit the news, our office has gotten [X calls / a noticeable uptick in inquiries]. The first thing I tell every one of those guys is [your actual response].
If you’ve seen the headlines about “Penisgate” at the 2026 Winter Olympics, where male ski jumpers allegedly used penile hyaluronic acid injections to gain a competitive edge in suit fittings, you probably have questions. International skiing officials have called those claims unsubstantiated. But the story has done one genuinely useful thing: it’s started a public conversation about a procedure that men have been quietly asking their doctors about for years.
Penile girth enhancement with hyaluronic acid filler isn’t new. It isn’t experimental. And it certainly isn’t just for athletes trying to game a 3D body scan. For the men who walk into our Nashville and Orlando practice asking about it, the reasons are personal. Confidence, intimacy, and feeling more comfortable in their own skin.
But there’s a lot of bad information out there right now. So let’s cut through it.
What Exactly Is This Procedure?
Penile girth enhancement using hyaluronic acid filler is a non-surgical, in-office procedure. A medical provider injects HA, a substance your body already produces naturally in your skin, joints, and connective tissues, into the shaft of the penis to add circumference.
If you’ve ever seen someone get lip filler or cheek filler, the concept is similar. The same class of hyaluronic acid products is used. The difference is the injection site and the goal: increased girth, a fuller flaccid appearance, and improved aesthetic proportion.
A few things this procedure is not:
- It is not a length procedure. HA filler adds volume, which increases girth. Some men notice a modest improvement in visible flaccid length due to the added weight, but that varies.
- It is not a treatment for erectile dysfunction. If you're experiencing ED, that's a separate clinical conversation.
- It is not permanent. HA is gradually absorbed by your body over time. Results typically last 12 to 18 months.
One thing patients need to know upfront. HA fillers are FDA-approved for cosmetic applications like facial soft tissue augmentation. Their use for penile enhancement is off-label. That means the filler product itself is FDA-approved, but this specific application hasn’t gone through a separate FDA review process. Off-label prescribing is standard practice in medicine. Your doctor has likely prescribed you something off-label before without either of you thinking twice about it. But you deserve to know that distinction before making a decision.
What the Published Research Actually Shows
Published scientific research supports that hyaluronic acid (HA) injections can increase penile girth and improve patient satisfaction in clinical settings, with generally manageable safety outcomes.
Clinical trials have directly evaluated HA fillers for penile girth enhancement. In a prospective, multicenter, patient- and evaluator-blinded randomized trial comparing HA to polylactic acid (PLA) fillers, both groups experienced significant penile girth increases at 24 weeks following injection. Men in the HA group showed a mean girth increase of approximately 22.7 ± 12.6 mm (about 2.3 cm), and both HA and PLA groups reported significant improvements in satisfaction with penile appearance and sexual life. There were no serious adverse events reported in this trial. [1]
A systematic review and meta-analysis that pooled data from four studies with 262-283 participants found that penile girth increased more with HA filler than with PLA filler (P = 0.01). Sexual satisfaction scores at 12 weeks were also significantly higher after HA augmentation compared with PLA. The meta-analysis found no significant difference in overall complication rates between HA and PLA groups. [2]
Observational and retrospective clinical data provide an additional real-world perspective. In a study of 230 men who underwent HA penile girth enhancement, mean penile circumference increased by approximately 2.66 cm at 1 month, 2.28 cm at 3 months, and 1.80 cm at 6 months. Reported complications occurred in about 4.3 % of patients, most commonly mild subcutaneous bleeding, nodules, or localized infection, with no systemic allergic reactions documented. [3]
Smaller prospective case series have also shown that HA injections for penile augmentation result in measurable increases in girth and improvements in psychological measures such as self-perception and sexual confidence over periods up to 12 months. [4]
Safety data compiled from systematic reviews and clinical reports indicate that adverse events are generally mild and manageable when the procedure is performed by trained clinicians in sterile medical settings. Documented risks include swelling, nodules, and localized inflammation. [5]
In summary, the peer-reviewed evidence indicates that HA penile fillers can produce increases in penile girth and improvements in satisfaction with sexual aesthetics, and that short-term safety profiles are acceptable in clinical practice. Larger controlled studies with extended follow-up beyond 24 weeks remain limited, and no high-quality long-term trials have yet established durability over many years.
The case reports that get shared on social media are alarming, and they should be. But when we look at where those complications happened, it’s almost always [unqualified providers / non-medical settings / non-HA substances]. The prospective data from controlled clinical settings tells a different story. What convinced us to offer this procedure was [specific data point or clinical observation]
What Happens During the Procedure: Our Protocol
Every practice does this a little differently. Here’s how we approach it at R3 Stem Cell in Nashville and Orlando.
The first thing we do is [consultation process]. we use [specific HA product] because [reason, such as longevity, viscosity, safety profile]. Our technique involves [cannula/needle, injection plane, etc.]. The whole procedure takes about [X minutes] in my hands. Patients tell us it feels like [their actual description]. Afterward, we tell them to expect [specific recovery timeline]. The thing most guys are surprised by is [unexpected detail from your clinical experience].
Most patients ultimately need in the range of 8 to 10 syringes to create a meaningful, proportional increase in girth, although the exact number depends on starting anatomy and personal goals.
How Long Results Last, and What Maintenance Looks Like
HA filler is not permanent. Your body breaks down hyaluronic acid naturally over time. Based on published data and what we see in our own practice, results typically hold for 12 to 18 months.
In our clinical experience, most men can expect results to last about a year or longer, depending on individual metabolism, activity level, and how their body processes HA.
Your Observations on Longevity
2-3 sentences on what YOU see clinically.
- In your experience, do results tend to last closer to 12 months or 18 months?
- Are there factors that seem to affect how long the filler lasts, such as activity level, metabolism, or the product used?
- What percentage of your patients come back for maintenance treatments?
Some men choose to do maintenance treatments annually. Others are satisfied with a single treatment and don’t return for a top-up. The option is there either way.
One of the key safety advantages of HA over permanent fillers or surgical implants is that it’s reversible. An enzyme called hyaluronidase can dissolve the filler if needed, whether due to an unwanted result, asymmetry, or a rare complication. That reversibility is a significant reason why HA has emerged as the preferred filler material for this application in the published literature.
Risks
No procedure is risk-free. And I’d rather you hear about the real risks from a provider than from a tabloid headline.
Common and expected: Swelling, bruising, and tenderness at the injection site. This is normal. It typically resolves within a few days to two weeks.
Uncommon but documented in the clinical literature: Nodule formation, mild asymmetry, filler migration, and localized infection. Published complication rates in controlled clinical settings range from roughly 1% to 4%, depending on the study. These are manageable. Nodules can be dissolved with hyaluronidase, infections respond to antibiotics, and asymmetry can often be corrected with a touch-up.
Rare but serious: The case reports Forbes mentioned are real. Severe infections progressing to sepsis and tissue necrosis requiring surgical intervention have been documented. But when you look at the details of those cases, the common threads are almost always the same: unqualified practitioners, non-medical settings, or non-HA substances being injected.
The biggest risk factor isn’t the filler itself. It’s [who’s doing it / where it’s done / patient non-compliance with aftercare / etc.]. In our practice, we’ve [seen X / not seen Y]. The way we minimize risk is [specific protocol detail]. We won’t perform this procedure on someone who [screening criteria].

Who Should and Shouldn't Consider This Procedure
Good candidates are men who:
- Are in good general health with no active infections or uncontrolled bleeding disorders
- Have realistic expectations. This adds girth, not length. It enhances, it doesn't transform
- Are motivated by personal confidence or intimacy goals, not pressure from a partner or social media
- Understand that results are temporary and may require maintenance
This procedure is not appropriate for men who:
- Are experiencing erectile dysfunction (that requires a different clinical evaluation)
- Have unrealistic expectations about the degree of change
- Are under 18
- Have active skin infections or conditions in the treatment area
The Patient You Remember
Share a brief anecdote about a patient interaction that captures why you offer this procedure.
- Is there a patient whose reaction after the procedure stuck with you?
- What's the most common thing men say at the follow-up appointment?
- Has a patient ever told you how this affected their confidence or relationship in a way that surprised you?
A 3-4 sentence real clinical anecdote, anonymized, carries more trust than any statistic
Why Your Choice of Provider Is the Most Important Decision You'll Make
The Olympics story is entertaining. But if there’s one takeaway that actually matters, it’s this: hyaluronic acid itself isn’t dangerous. It’s a substance your body already makes. The risk comes from who injects it, where they inject it, what product they use, and what protocols they follow.
When evaluating a provider for this procedure, ask these questions.
A licensed physician (MD or DO) is the baseline. Board certification in urology, dermatology, plastic surgery, or sexual medicine indicates additional specialized training. Be cautious of med spas or non-physician practitioners offering this without direct physician supervision.
Experience matters. This is a specialized injection technique with unique anatomical considerations.
It should be a named, FDA-approved hyaluronic acid filler being used off-label, not an unbranded, compounded, or imported product of unknown origin.
A provider who performs the injection and sends you home without structured follow-up is a red flag. You should have scheduled follow-up appointments, clear written aftercare instructions, and direct access to your provider if something doesn’t look or feel right.
A responsible provider turns away patients who aren’t good candidates. If someone is willing to inject anyone who walks through the door and pays, keep walking.
Your Credentials and Approach
3-5 sentences about your specific qualifications, experience, and philosophy.
- What is your medical training and board certification?
- How many penile HA filler procedures have you performed?
- What drew you to offering this procedure?
- What sets your approach apart from other providers in the Nashville and Orlando areas?
- What is your practice's philosophy on patient selection and informed consent?
The Bottom Line
The “Penisgate” headlines made for a good laugh. But for men in Nashville and Orlando who have been quietly wondering about this procedure, maybe for months or years, the real conversation isn’t about ski jumpers. It’s about whether this is a safe, effective option for you, performed by a provider you trust, with realistic expectations about what it can and can’t do.
The published evidence says it can be. The key word is can, because outcomes depend heavily on the provider, the product, the protocol, and the patient.
If you’re considering it, the right first step is a private, no-pressure consultation where you can ask every question on your mind and get honest answers. That’s what we’re here for.
Frequently Asked Questions
Include actual price or price range. Being transparent about cost is one of the strongest trust signals you can give. Patients are already Googling “penile filler cost Nashville.” If pricing varies based on filler volume, explain the range and what factors affect it.
Most patients describe the sensation as pressure rather than sharp pain. We use [local anesthetic / nerve block, Dr. Worthington to specify] to minimize discomfort. On a scale of 1 to 10, most of our patients rate the discomfort at [Dr. Worthington to provide his patients’ typical range].
No. We advise abstaining from sexual activity for 7 to 10 days to allow the filler to settle and reduce the risk of displacement. We also provide a specific aftercare and molding protocol to help achieve the most natural, even result.
The enhancement is visible and tactile. Your partner will likely notice the change in girth. However, the result is designed to look and feel natural. HA filler integrates with your existing tissue and does not feel artificial.
Published data from studies involving hundreds of patients shows no reported cases of erectile dysfunction or loss of penile sensation following HA filler injection. The filler is placed in the subcutaneous tissue, not in the erectile chambers or near the major nerve bundles.
Yes. Hyaluronidase, an enzyme, can dissolve HA filler. This is one of the primary safety advantages over permanent fillers or surgical implants.
Published studies report average girth increases of approximately 1.5 to 2.3 cm, depending on the volume injected. Results are customizable. During your consultation, Dr. Worthington will discuss realistic expectations based on your anatomy and goals.
Because HA is both temporary (it dissolves naturally over 12 to 18 months) and reversible (hyaluronidase can dissolve it immediately), you’re never locked into a result you’re unhappy with. Adjustments and corrections are possible.
