Penuma is a brand of soft silicone implant that a surgeon slides under the skin of the penis to make it look thicker, and to add a little flaccid length. It is a cosmetic device for the appearance of the penis, not a treatment for erectile dysfunction, and it is licensed for men only. If you have read about it and are weighing a trip to Bangkok to have it done, this guide is written to give you the straight version: what the device actually is, how it differs from the inflatable and malleable implants used for ED, who is and is not a candidate, what the published results and complication numbers really show, and what girth enhancement realistically costs in Thailand.
One point belongs at the very top, because it shapes everything below. Penuma itself is an FDA-cleared device that is, as of 2026, licensed for use almost entirely inside the United States through a small network of trained surgeons. Medical-tourism listings that advertise "Penuma in Bangkok" are usually describing a different cosmetic girth procedure (dermal filler or fat transfer) or a standard ED penile prosthesis, not the branded Penuma implant. We think it is more useful to explain Penuma honestly, then show you the girth options that are genuinely available in Bangkok and what they cost, than to quote a Penuma price that does not reflect reality. Any of these procedures is elective surgery on a sensitive area and requires an in-person medical consultation before anyone can tell you whether it is appropriate for you.
What Penuma actually is
Penuma is a crescent-shaped piece of medical-grade solid silicone. During a roughly 45 to 60 minute outpatient operation, usually under general or heavy sedation anaesthesia, the surgeon makes an incision (commonly near the base of the penis or in the pubic or upper-scrotal area), creates a space under the penile skin and above the deeper structures, and seats the implant there like a soft sleeve. The skin is closed over it, so nothing is visible from outside once healing is complete. The goal is a wider, fuller-looking penis, mostly in the flaccid state, with a modest gain in flaccid length as well.
The device has been granted several 510(k) clearances by the US Food and Drug Administration over the years, and as of May 2022 it became, in the FDA's framing, the only device cleared specifically for cosmetic enhancement of the penis. The Cleveland Clinic, in its plain-language overview of penis enlargement surgery, describes the Penuma silicone implant as "the only product of its type with FDA approval." A peer-reviewed update by Wilson and Picazo in the International Journal of Impotence Research likewise describes it as a medical-grade silicone implant inserted subcutaneously for aesthetic enhancement of the flaccid penis. That FDA clearance is for cosmetic appearance. It is not a clearance to treat erectile dysfunction, and that distinction matters more than any other on this page.
How Penuma differs from inflatable and malleable ED implants
It is easy to lump every "penile implant" together, but Penuma sits in a completely different category from the prostheses urologists use for erectile dysfunction.
An ED penile prosthesis treats the inability to get or keep an erection. The Cleveland Clinic's overview of surgical penile implants explains that these devices are placed inside the erectile chambers, the corpora cavernosa, the two columns of spongy tissue that fill with blood to make the penis hard. There are two families:
An inflatable implant (for example a three-piece device) stays soft until you pump fluid into cylinders inside the penis, producing a firm erection on demand, then drains back to flaccid. We cover these in our guide to inflatable penile implants and the Coloplast Titan.
A malleable (semi-rigid) implant is a pair of bendable rods inside the erectile chambers that keep the penis permanently firm; you bend it up for sex and down otherwise. See malleable penile implants.
Penuma is none of these. It does not go inside the erectile chambers, it does not create or improve an erection, and it has no pump, rods, or fluid. It sits in the soft tissue above the erectile bodies, purely to change how the penis looks. A man with normal erections is the intended Penuma candidate; a man who cannot get an erection is, instead, a candidate for an ED prosthesis. The closest cosmetic cousin to Penuma is Himplant, another subcutaneous silicone implant; you can compare the category in our overview of Himplant penile enlargement and the broader penile implant surgery options.
Who is a candidate, and who is not
Penuma is marketed to healthy adult men who are bothered by the girth or flaccid appearance of their penis and who already have normal erectile function. Good candidates are generally non-smokers (or willing to stop), at a stable weight, free of active genital infection, realistic about what a cosmetic implant can and cannot do, and screened for the psychological side of the decision.
Penuma is not the right path, and a responsible surgeon should say so, for several groups:
Men whose real problem is erectile dysfunction. The fix there is an ED prosthesis or medical treatment, not a cosmetic sleeve. If that is you, start with ED medication options and a urology assessment.
Men chasing erect length. Penuma mainly changes flaccid girth and appearance; it is not a reliable erect-lengthening operation.
Men with body dysmorphic disorder or small penis anxiety about an anatomically normal penis. The Cleveland Clinic is blunt that most men who want enlargement do not medically need it, and that the concern can reflect a psychological condition rather than a physical one. Surgery does not treat that, and may worsen it.
Men with active infection, poorly controlled diabetes, bleeding disorders, or significant Peyronie's curvature, where added risk or a different operation applies.
This is exactly the kind of decision that should not be made from a website. A consultation exists to separate a cosmetic wish from a treatable medical problem.
Contraindications and cautions
Beyond candidacy, specific situations argue against a subcutaneous silicone implant or call for it to be deferred: any current skin or urinary infection, uncontrolled diabetes or immunosuppression that impairs healing, a bleeding or clotting disorder or blood-thinning medication that cannot be paused, a known sensitivity to silicone, untreated body dysmorphic disorder, and unrealistic expectations. Smoking is a major one, because nicotine starves healing skin of blood supply and raises the odds of wound breakdown and implant exposure over a device that sits just under the skin. Previous genital surgery or scarring can also make the tissue plane harder to work with. None of this is a checklist you can clear yourself; it is what the surgeon screens for.
The procedure, step by step
While techniques vary by surgeon, a Penuma-type girth implant generally follows this sequence:
Assessment and sizing. The surgeon measures your anatomy and selects an implant size (the device comes in a small number of sizes). Circumcision is often required either beforehand or at the same time, which can add cost.
Anaesthesia. The operation is typically done under general anaesthesia or deep sedation as a day case.
Incision and pocket. Through an incision (often at the base of the penis or in the pubic or upper-scrotal crease, chosen to hide the scar), the surgeon develops a space under the penile skin, above the deeper fascia and erectile bodies.
Implant placement. The crescent-shaped silicone implant is positioned around the shaft within that pocket and secured so it sits evenly.
Closure and dressing. The skin is closed, a compressive dressing is applied, and a drain is sometimes left to limit fluid collection.
You go home the same day or after a short stay. This is genuinely a surgical procedure, not a lunchtime injection, and the recovery reflects that.
Staged recovery
Recovery is gradual and demands patience. The general shape of it looks like this, though your surgeon's instructions always take precedence.
Stage | Timeframe | What to expect |
Early | Days 0 to 7 | Swelling, bruising and discomfort; compressive dressing worn; limited activity; keep the wound clean and dry. |
Wound healing | Weeks 1 to 3 | Stitches dissolve or are removed; swelling slowly settles; desk work often resumes within a week or so; no sex, no heavy lifting. |
Tissue settling | Weeks 3 to 6 | Bruising fades; the implant begins to soften into place; gentle return to light activity as advised. |
Return to sex | About 6 to 8 weeks | Most surgeons advise waiting roughly 6 to 8 weeks before intercourse; some swelling and firmness can persist. |
Final result | 3 to 6 months | Swelling fully resolves and the final look and feel become apparent. |
Strict adherence to dressing, hygiene and activity instructions is not optional with an implant that sits just under the skin; it is the single biggest thing you control to lower the risk of fluid collection, infection, or the implant working its way toward the surface.
What the results data actually show
Independent, published outcome data on Penuma come mainly from urology centres in the United States, and the honest summary is that satisfaction is high for many men, but the procedure also carries a real and non-trivial complication and revision rate. Both halves of that sentence are true at once.
The most useful single study is a 2024 single-surgeon series by Salkowski and Levine in Therapeutic Advances in Urology (92 cases). They reported an average flaccid length increase of about 2.5 cm (a 44 percent increase) and an average girth increase of about 3.1 cm (a 32 percent increase). On satisfaction, 82 percent of men were satisfied or very satisfied with the appearance, and 75 percent said they would have the surgery again. Those are meaningful gains for a flaccid-appearance procedure.
The same study is also where the risk picture comes into focus, and it shows that surgical approach matters. Seroma (a fluid collection) requiring drainage occurred in about 12 percent of cases. Overall operative revision was around 7 percent, but it split sharply by technique: revision was 13 percent with the traditional infrapubic approach versus 2 percent with a lateral scrotal approach, and implant removal was 21 percent with the infrapubic approach versus 6 percent with the lateral scrotal approach. In plain terms, a meaningful minority of men needed a second operation, and the surgeon's chosen technique influenced that risk. A separate multicentre update by Wilson and Picazo similarly reported high patient and partner satisfaction with what the authors called acceptable adverse outcomes.
For honest context, a 2025 single-centre case series by Barham and colleagues in The Journal of Sexual Medicine looked specifically at 16 men who came in with Penuma complications or for removal (all originally implanted elsewhere). Among that selected group, findings included distal protrusion of the implant, post-removal curvature and shortening, sensory changes, localised infection, and some new erectile dysfunction, and most went on to scar-revision surgery. That study is not a complication rate for the average patient, because it deliberately collected problem cases, but it documents the kind of severe outcomes that can occur and reinforces why surgeon selection and follow-up matter so much. The takeaway is not that Penuma always goes wrong; it is that this is real surgery with real downside, and the results depend heavily on who does it.
Risks and side effects
Expected, usually self-limiting effects in the early weeks include swelling, bruising, discomfort, temporary changes in sensation, and altered appearance while healing. The complications that matter more, and that the literature above documents, include:
Seroma, a collection of fluid around the implant, sometimes needing drainage (around 12 percent in the series above).
Infection, which with an implant can mean the device has to be removed.
Migration or shifting of the implant, or distal protrusion where it presses toward the skin surface.
Implant exposure or extrusion through the skin, a particular risk if healing is poor or the man smokes.
Scarring, skin tethering, or a cosmetic result that disappoints, sometimes requiring scar revision.
Penile curvature, shortening, sensory change, or new erectile difficulty, reported especially after complications and removal.
The possibility of needing one or more further operations, including explant.
When to seek urgent care
After surgery, contact your surgeon or seek urgent medical care promptly if you develop a fever, spreading redness, warmth or worsening pain around the wound, pus or foul-smelling discharge, a part of the implant becoming visible or pushing through the skin, a rapidly enlarging or very tense swelling, the skin over the implant turning dusky or black, or inability to pass urine. These can signal infection, a significant fluid collection, or threatened skin breakdown over the device, and they are time-sensitive.
Girth enhancement in Bangkok: pricing reality
Here is the part the aggregator listings get wrong. The genuine branded Penuma device is, as of 2026, licensed for use overwhelmingly within the United States, where the all-in procedure typically runs about USD 16,000 to 21,000 and sometimes higher once circumcision and add-ons are included. Listings that quote a cheap "Penuma" price in Thailand are almost always pricing a different girth procedure (filler or fat transfer) or a standard ED prosthesis. So the useful question for a Bangkok trip is not "what does Penuma cost here," but "what girth options are actually available here, and what do they cost." Treat every figure below as indicative and confirm exact inclusions at consultation, because quotes vary by clinic, product volume, and anatomy.
Girth option in Bangkok | Typical price (THB) | Typical price (USD approx.) | Notes |
Hyaluronic acid dermal filler (non-surgical girth) | THB 54,000 – 115,000 | USD 1,500 – 3,200 | Temporary, lasts roughly 1 to 2 years; priced per cc, often 10 to 30 cc; no implant. See penis filler guide. |
Autologous fat transfer (girth) | THB 90,000 – 180,000 | USD 2,500 – 5,000 | Uses your own fat; semi-permanent, with some volume reabsorbed within ~24 months. |
Genuine branded Penuma implant | Not generally available in Thailand | USD ~16,000 – 21,000 (US pricing) | FDA-cleared device, performed mainly in the US by trained surgeons; verify any "Penuma" claim carefully. |

How Bangkok compares for cosmetic girth
Option / location | Typical cost | Versus Bangkok |
Bangkok dermal filler or fat transfer | USD 1,500 – 5,000 | Baseline |
Penuma in the United States | USD 16,000 – 21,000+ | Several times more expensive, but it is the actual FDA-cleared device |
The headline is that Bangkok is genuinely cheaper for cosmetic girth, but mostly because the affordable Bangkok options are fillers and fat transfer, not because you are getting a discounted Penuma. For lower-cost, non-surgical or reversible routes that many men should consider first, see penis filler in Bangkok and the comparison of penile lengthening versus penis fillers.
What drives the cost
Whichever route you take, the price is shaped by the same handful of factors: the product or device itself (a silicone implant is far more expensive than a syringe of filler), the surgeon's experience in genital cosmetic work, the facility tier and operating-room fees, anaesthesia, whether circumcision is needed, and the quality and length of aftercare and follow-up. A quote far below the ranges above is a reason to ask exactly what device or product is included, not a bargain to grab.
Comparing the main options
Option | What it does | Permanence | Rough Bangkok cost | Main trade-off |
Penuma / subcutaneous silicone implant | Cosmetic flaccid girth and appearance | Long-lasting but removable | Not generally available (US ~USD 16,000–21,000) | Real surgery; seroma/revision risk; device largely US-only |
Hyaluronic acid filler | Adds flaccid and erect girth | Temporary (about 1 to 2 years) | THB 54,000 – 115,000 | Wears off; needs repeat treatment; lumpiness possible |
Autologous fat transfer | Adds girth using your own fat | Semi-permanent | THB 90,000 – 180,000 | Partial reabsorption; can be uneven |
Ligamentolysis (suspensory ligament release) | Adds flaccid length appearance | Permanent (structural) | Varies by surgeon | Length only, not girth; scarring and stability concerns |
ED penile prosthesis (inflatable/malleable) | Restores erections (function, not cosmetics) | Permanent device | THB ~480,000+ | Different indication entirely; only for erectile dysfunction |
If your underlying concern is erections rather than appearance, the comparison you actually want is between penile implants and shockwave or PRP, not between cosmetic girth options.
Why this needs a consultation, and how Menscape helps
There is no responsible way to tell a man, online, whether a cosmetic penile procedure is right for him. The decision turns on your anatomy, your erectile function, your general health, the realism of your expectations, and the psychological side of the request, all of which require an in-person assessment. Penuma and its alternatives are elective procedures on a sensitive, functionally important part of the body, and a good clinic will sometimes tell you that no procedure is the right answer.
Menscape is a men's health clinic in Bangkok built around exactly this kind of conversation: a private, discreet, male-only setting, an honest assessment of whether your concern is cosmetic or medical, transparent pricing on the options genuinely available here, and clear aftercare. If you are considering girth enhancement or have read about Penuma and want to understand your real choices, book a confidential consultation with Menscape to discuss your anatomy, the realistic options, costs, and expected results.
Frequently Asked Questions
Is Penuma actually available in Bangkok?
Not in practice. The genuine branded Penuma device is, as of 2026, licensed for use overwhelmingly inside the United States through a small network of trained surgeons. Listings advertising 'Penuma in Bangkok' are usually describing a different cosmetic girth procedure, such as hyaluronic acid filler or fat transfer, or a standard erectile-dysfunction prosthesis, rather than the branded Penuma implant. If a Thai clinic quotes you a Penuma price, ask exactly what device is being implanted and request documentation, because the realistic girth options available in Bangkok are fillers and fat transfer.
Does Penuma treat erectile dysfunction?
No. Penuma is a cosmetic implant cleared by the FDA for the appearance of the penis, not for erectile function. It sits in the soft tissue above the erectile chambers and does not create or improve an erection. Men who cannot get or keep an erection are candidates for a different device, an inflatable or malleable penile prosthesis placed inside the erectile chambers, or for medical treatment of ED, not for Penuma.
How is Penuma different from an inflatable penile implant?
An inflatable penile implant is a functional device placed inside the erectile chambers to produce an erection on demand using a pump and fluid; it treats erectile dysfunction. Penuma is a crescent-shaped silicone sleeve placed under the penile skin, above the erectile bodies, purely to make the flaccid penis look thicker and slightly longer. One restores erections; the other changes cosmetic appearance. They are different operations for different problems.
How much girth and length does Penuma actually add?
In a published 2024 single-surgeon series of 92 cases, Penuma added on average about 3.1 cm of girth (a 32 percent increase) and about 2.5 cm of flaccid length (a 44 percent increase). Results vary with implant size and individual anatomy, and the gains are mainly in the flaccid state. It is not a reliable way to increase erect length, and individual outcomes differ.
What are the main risks of a Penuma-type implant?
The most reported issues are seroma (a fluid collection), which needed drainage in about 12 percent of cases in one series, infection (which with an implant can mean removal), migration or protrusion of the implant, exposure through the skin, scarring or a disappointing cosmetic result, and the possibility of needing a further operation. Operative revision was around 7 percent overall in that series and varied by surgical approach. Smoking notably raises the risk of poor healing and implant exposure.
How satisfied are men after Penuma?
Satisfaction in published studies is generally high. In the 2024 series, 82 percent of men were satisfied or very satisfied with the appearance and 75 percent said they would have the surgery again, and a multicentre update reported high patient and partner satisfaction. That said, a minority experience complications or need revision, so satisfaction and risk both have to be weighed; outcomes depend heavily on patient selection and the surgeon's experience.
How long is recovery and when can I have sex again?
Most men return to desk work within roughly a week, but the implant takes time to settle. Surgeons typically advise waiting about 6 to 8 weeks before intercourse, and the final look and feel become clear over 3 to 6 months as swelling fully resolves. Following dressing, hygiene and activity instructions closely during this time is the main thing you control to reduce complications.
Can a Penuma implant be removed?
Yes. It is designed to be removable or replaceable, and removal is sometimes necessary because of infection, migration, protrusion, or dissatisfaction. Removal is itself an operation, and some men report curvature, shortening, sensory change or erectile difficulty after an implant is taken out, so removal is not always a clean reset. This is one more reason the initial decision and surgeon choice matter.
Will there be a visible scar?
The incision is usually placed at the base of the penis or in the pubic or upper-scrotal crease so the scar is hidden once healing is complete, and a scrotal approach in particular is associated with a less visible scar and less seroma in one study. Scarring varies between individuals, and some men need a minor scar revision, so a discreet scar is the goal rather than a guarantee.
What are cheaper alternatives for girth in Bangkok?
The realistic, available options in Bangkok are non-surgical hyaluronic acid filler (roughly THB 54,000 to 115,000, temporary and lasting about 1 to 2 years) and autologous fat transfer (roughly THB 90,000 to 180,000, semi-permanent with some reabsorption). These are far less expensive than a Penuma procedure and are reversible or repeatable, which is why many men consider them first. A consultation can help you compare them against your goals.
