The Penuma implant is one of the first FDA-cleared silicone implants designed specifically for cosmetic penile enhancement. Unlike the inflatable or malleable implants used to treat erectile dysfunction, Penuma sits *under the penile skin*, above the erectile chambers, purely to change appearance: more flaccid length, more girth, and a fuller, more symmetrical look.
It is a real surgical procedure with real trade-offs. This guide gives you the clinical picture most marketing pages leave out: transparent Bangkok pricing, quantified results, honest complication and removal rates from peer-reviewed studies, who should *not* have it, and how Penuma compares to Himplant, functional implants, and fillers, so you can make an informed decision.
This article is educational and is not medical advice. Penuma is a surgical implant. A face-to-face consultation, physical examination, and medical evaluation are required to confirm whether you are a suitable candidate. Outcomes vary by anatomy, surgeon, and aftercare.
Quick summary
What it is: A soft, medical-grade silicone implant inserted beneath the penile skin to enhance *cosmetic* size, primarily flaccid girth and flaccid length.
What it is not: It is not a treatment for erectile dysfunction (ED), and it generally does not increase *erect* length. Men with ED need a functional inflatable or malleable implant instead.
Regulatory status: Penuma is FDA-cleared via the 510(k) pathway (meaning it is judged "substantially equivalent" to an existing device), this is *not* the same as FDA *approval* after enlargement-efficacy trials.
Bangkok cost: Roughly 360,000-580,000 THB (about 10,000-16,000 USD) all-in, typically below comparable US centers (16,000-24,000 USD), though premium Bangkok quotes can approach the lower end of US pricing.
Honest caveat: Published series report device removal in roughly 6-21% of patients depending on surgical approach. It is reversible only by a second operation, which can leave scarring.
What Is the Penuma Implant?
Penuma is a crescent-shaped sheet of soft, medical-grade silicone that a surgeon implants in a pocket created between the penile skin and the erectile bodies (the *corpora cavernosa*, the two cylinders that fill with blood during an erection). Because it sits *on top of* and *around* the erectile tissue rather than inside it, it changes the outer dimensions of the penis without entering the structures responsible for erections.
Key characteristics:
FDA-cleared for cosmetic penile enhancement through the 510(k) route, see the "cleared vs. approved" note below.
Soft silicone designed to move with the penis.
Manufactured in a small number of sizes (commonly labelled L, XL, XXL) selected to your anatomy.
Intended as a long-term enhancement, not a permanent guarantee, implants can need revision or removal.
Removable, but only via a second surgery.
"Cleared" vs. "Approved", Why It Matters
This distinction is frequently blurred in marketing. FDA 510(k) clearance means the device was allowed to market because it is "substantially equivalent" to a legally marketed predicate device. It does not mean the FDA reviewed and endorsed cosmetic-enlargement *outcomes* in clinical trials, the way it does for a fully *approved* (PMA) product. Treat "FDA-cleared" as a manufacturing/safety equivalence statement, not proof of cosmetic efficacy. (See the FDA 510(k) explainer in our sources.)
Quantified Results: What Penuma Actually Changes
This is where realistic expectations matter most. Penuma primarily increases the flaccid appearance of the penis.
Girth: Published case series report meaningful circumference gains, commonly in the range of roughly 1.5-2.5 cm (about 0.6-1 inch) of added flaccid girth, varying by implant size and anatomy.
Flaccid length: Many men gain visible flaccid length and "hang," but the amount varies widely.
Erect length: Penuma generally does not increase erect length. Do not expect a longer erection. If erect length is your goal, suspensory ligament release / penile lengthening addresses a different anatomy and has its own trade-offs.
Satisfaction: In peer-reviewed outcome studies, the *majority* of men report satisfaction with cosmetic results, but a non-trivial minority do not, and satisfaction depends heavily on surgical technique and pre-operative counselling.
In short: Penuma is a device for the flaccid penis, it primarily makes the penis look and feel fuller and longer when soft. Any change to the erect penis is less predictable, chiefly affecting girth rather than length; reliable erect-girth gain is not well established, and the implant does not make erections longer.
Penuma Cost in Bangkok (2026): THB + USD Pricing
Cost is one of the most-searched questions about Penuma, and transparency here is part of choosing a safe clinic. The figures below are indicative ranges based on current Bangkok-market consensus and international price reporting; confirm exact, itemised pricing at your consultation, as the final quote depends on implant size, surgeon, facility, and whether ancillary procedures (such as a circumcision revision) are needed.
Item | Bangkok (THB) | Bangkok (USD) | Typical US Range (USD) |
Penuma implant package (all-in) | ฿360,000 - ฿580,000 | $10,000 - $16,000 | $16,000 - $24,000 |
Implant device | included | included | ~$5,000 (device alone) |
Surgeon's fee | included | included | varies |
Anesthesia (general) | included | included | $1,000 - $2,500 |
Facility / day-surgery | included | included | $2,000 - $4,000 |
Standard follow-up visits | usually included | usually included | varies |
Revision / removal surgery (if needed) | ฿150,000 - ฿400,000+ | $4,000 - $11,000+ | $5,000 - $15,000+ |
Bangkok savings: A typical Bangkok all-in package runs roughly 15-40% below comparable US centers, in line with the international Penuma price range (~$10,000-$16,000 across Thailand, Turkey, and Mexico). Note that premium Bangkok quotes can approach the lower end of US pricing, so the saving is not guaranteed at the top of the range. Medical-tourism reporting for general penile-implant surgery in Thailand cites larger savings versus US list prices, but cosmetic Penuma specifically sits at the higher, premium end of the Thai market.
What Influences the Final Price
Implant size (L / XL / XXL).
Surgeon experience and case volume with this specific proprietary device.
Hospital vs. day-surgery facility and length of stay.
Ancillary procedures, a circumcision or skin revision is sometimes required and can add roughly $1,000-$3,000.
Revision policy, ask, in writing, what a revision or removal would cost and whether any of it is covered.
A genuinely transparent clinic will hand you an itemised quote that names the device, the surgeon's fee, anesthesia, facility, included follow-ups, and the revision/removal policy. If a quote is a single round number with no breakdown, ask for the detail. See our broader penis enlargement service pricing for context across options.
Who Is, and Isn't, a Candidate
Penuma may suit men who
Want long-lasting cosmetic enhancement of flaccid size and girth.
Are bothered by perceived size or asymmetry with otherwise normal erections.
Prefer a one-time surgical result over repeated filler injections.
Have realistic, specific expectations and stable mental health.
Penuma is NOT appropriate if you
Have erectile dysfunction and want firmness restored, you need a functional penile implant, not Penuma.
Want a longer erect penis (Penuma generally does not deliver this).
Have an active infection anywhere, particularly genital or urinary.
Have uncontrolled diabetes (impaired wound healing and higher infection risk).
Smoke / vape nicotine, strongly linked to wound-healing failure and implant complications; surgeons typically require cessation before surgery.
Have a bleeding or clotting disorder, or cannot safely stop blood thinners.
Have had prior penile or groin surgery that compromises the tissue planes (requires careful evaluation).
Have significant Peyronie's disease (scarring that curves the penis), needs assessment first.
Have features of body dysmorphic disorder or expectations that no surgery can meet, ethical surgeons will decline and refer for evaluation.
A medical evaluation, including pre-operative labs and a review of medications, is mandatory. This is a screening list, not a substitute for clinical assessment.
The Penuma Procedure, Step by Step
1. Consultation, sizing, and fitness-for-surgery
Detailed measurements and standardised photographs.
Implant-size selection matched to your anatomy.
Medical history, examination, and pre-operative bloodwork.
Instructions to stop nicotine and, if applicable, pause blood-thinning medication under medical guidance.
A frank discussion of realistic results and risks.
2. Surgery (approximately 60-120 minutes)
Performed under general anesthesia (occasionally regional, surgeon-dependent):
A small incision is made, commonly at the base of the penis or the upper groin crease, where the scar is most hidden.
A precise pocket is created in the plane above the corpora cavernosa, beneath the skin.
The Penuma silicone implant is inserted and positioned for symmetry.
Position and symmetry are checked and refined.
The incision is closed, usually with dissolving sutures. A drain may be placed.
The implant is positioned subcutaneously (just under the skin), *not* inside the erectile chambers, which is why it does not mechanically interfere with the erection itself.
3. Immediate post-surgery care
A drain may stay in place for 24-48 hours.
A compression dressing controls swelling.
Light walking is encouraged within the first few days to reduce clot risk.
You will be given antibiotic and wound-care instructions and a follow-up schedule.
Recovery Timeline
Phase | What to expect |
Week 1-2 | Swelling and bruising peak then begin to settle. Mild-to-moderate discomfort is normal. Keep the wound clean and dry; attend the early follow-up. |
Week 3-4 | Shape becomes visibly more stable. Light daily activity and desk work usually resume. |
Week 6-8 | Sexual activity is usually permitted after surgeon clearance, most protocols restrict it for at least 6-8 weeks, consistent with general penile-implant recovery guidance. |
3-4 months | Swelling resolves and the final aesthetic result settles. Sensation typically normalises, though some men report lasting changes. |
Seek urgent medical care if you develop: spreading redness or warmth, increasing pain, fever, foul-smelling or pus-like discharge, a wound that opens, the implant becoming visible through the skin, or rapidly worsening swelling. These can signal infection, seroma, or erosion and may require prompt treatment or implant removal.
Risks, Complications, and How Common They Really Are
Penuma is surgery, and the honest risk picture is more substantial than promotional pages suggest. Peer-reviewed outcome studies report the following.
More common / expected:
Seroma (fluid collecting around the implant), reported in roughly 5% in some series, but up to ~12% requiring drainage in a recent two-approach study (Salkowski & Levine, 2024); usually managed with drainage.
Swelling, bruising, temporary discomfort, near-universal early on.
Scar tissue formation around the implant.
Less common but important:
Infection, reported around 1-3%, occasionally higher; may require antibiotics or implant removal.
Implant shifting, flaring, or distal migration, the implant can move or feel uneven, sometimes needing revision.
Erosion, the implant can erode toward or through the skin; a 2024 multi-institutional series (Siegal et al.) found erosion higher than previously reported, so it should not be dismissed as merely rare.
Dissatisfaction with cosmetic outcome, a documented reason for removal.
Device removal and revision, the key number: Published surgical series report device-removal rates of roughly 6% to 21%, with the higher figures linked to the older infrapubic surgical approach and lower figures to the lateral scrotal approach (Salkowski & Levine, 2024: about 6% removal / 2% revision with the lateral scrotal incision versus 21% removal / 13% revision with the infrapubic approach). A separate single-center series reported removal in about 12% of patients (for reasons including cosmetic dissatisfaction, erosion, and infection). These are not trivial numbers, and you should weigh them seriously.
Choosing a high-volume, appropriately trained surgeon and following aftercare meaningfully reduces, but does not eliminate, these risks.

On Reversibility and "Natural Feel", An Honest Note
Reversibility is a second operation, not a clean undo. Removing the implant can leave scar tissue, skin changes, or cosmetic deformity, and it carries its own recovery and cost. Outcomes reported in a selected explant cohort (Barham et al., JSM 2025), including post-removal curvature, illustrate that removal is not without consequence; note these are outcomes within a removal population, not population-wide rates.
"Natural look and feel" is the goal, not a guarantee. *Many* men are happy with how the result feels, but patient-reported outcomes are mixed: some report palpable implant edges, firmness, or changes in sensation. Frame your expectations accordingly.
How Penuma Compares: Penuma vs. Himplant vs. Functional Implant vs. Fillers
Choosing the right procedure depends on whether your goal is cosmetic size or restoring erections, these are different problems with different devices.
Feature | Penuma (cosmetic) | Himplant (cosmetic) | Functional implant (Titan / AMS) | Fillers / fat transfer |
Primary goal | Flaccid girth + length | Flaccid girth + length | Treat ED / restore rigidity | Girth (mostly) |
Treats erectile dysfunction? | No | No | Yes | No |
Increases erect length? | Generally no | Generally no | Restores erection, not length | No |
Material | Soft silicone sheet | Soft silicone (subcutaneous) | Inflatable / malleable device inside erectile bodies | Hyaluronic acid or own fat |
Permanence | Long-term (removable by surgery) | Long-term (removable by surgery) | Permanent device | Temporary (fillers) / partial resorption (fat) |
Downtime | ~6-8 weeks | ~6-8 weeks | ~6 weeks | Minimal |
Reversibility | Second surgery | Second surgery | Removal ends natural erections | Higher (HA dissolvable) |
Bangkok cost (indicative) | ฿360k-580k | similar premium range | ฿280k-580k+ | lower, but repeated |
For functional concerns, compare the Titan / Coloplast and inflatable implant options. For the other leading cosmetic implant, see our Himplant guide. If you are weighing surgery against injections, read fillers vs. surgery.
Choosing a Safe Clinic in Bangkok (and Red Flags)
Penuma is a proprietary device implanted by a limited number of credentialed surgeons worldwide. That makes surgeon selection more important here than for many procedures, and it is worth confirming a clinic uses the actual trademarked Penuma device rather than a generic silicone-sleeve implant.
Green flags, look for:
A surgeon who is specifically trained and credentialed for this device, with a case volume they can quote.
A named, licensed urologist or genital surgeon, in Thailand, ask for the Thai Medical Council license number (reputable Bangkok clinics list these).
An itemised written quote and a clear, written revision/removal policy.
Honest counselling that quantifies results *and* complication rates, and that screens you out if you are not a candidate.
Accredited facility and proper anesthesia coverage.
Red flags, walk away if you see:
Guarantees of a specific size gain, or claims of erect-length increase.
"FDA-approved" language (it is *cleared*, not approved) or pressure to decide quickly.
No itemised pricing, or no answer on what revision/removal would cost.
Reluctance to discuss complication and removal rates.
No verifiable surgeon credentials or license number.
Why Some Men Choose Bangkok
Established aesthetic and urological surgery infrastructure and high-volume genital surgeons.
Lower cost than many Western Penuma centers for comparable care.
Modern, discreet facilities and strong privacy norms.
Coordinated international-patient services and structured follow-up.
These advantages only count when paired with the safe-clinic checks above. Cost should never be the only deciding factor for an elective implant.
Bottom Line
Penuma can deliver a meaningful, long-lasting improvement in cosmetic flaccid size and girth for the right candidate, but it is genuine surgery with real costs, a defined recovery, and documented complication and removal rates that you should understand before committing. It does not treat ED and generally does not lengthen erections.
If you are weighing Penuma, the most valuable next step is a confidential consultation and medical evaluation to confirm candidacy, get an itemised quote, and compare it against Himplant, functional implants, and non-surgical options.
A consultation and full medical evaluation are required before any surgical implant. Book a confidential consultation with Menscape Bangkok for sizing, candidacy assessment, and transparent surgical planning.
Frequently Asked Questions
How much size does Penuma actually add?
Published case series report meaningful flaccid girth gains, commonly around 1.5-2.5 cm (about 0.6-1 inch) of added circumference, plus variable flaccid-length gain. Importantly, Penuma generally does NOT increase erect length, and reliable erect-girth gain is not well established. The change is primarily to how the penis looks and feels when soft.
Does Penuma treat erectile dysfunction?
No. Penuma is a cosmetic implant placed under the skin, above the erectile chambers. It does not improve rigidity or treat ED. Men with erectile dysfunction need a functional inflatable or malleable implant placed inside the erectile bodies, which is a different device and procedure.
Is Penuma FDA-approved?
Penuma is FDA-cleared through the 510(k) pathway, meaning it was deemed substantially equivalent to an existing device. That is not the same as FDA approval based on cosmetic-enlargement efficacy trials. Be cautious of clinics that advertise it as fully 'FDA-approved.'
How much does Penuma cost in Bangkok?
An all-in Bangkok package typically runs about 360,000-580,000 THB (roughly 10,000-16,000 USD), versus about 16,000-24,000 USD at comparable US centers. Premium Bangkok quotes can approach the lower end of US pricing, so the saving is not guaranteed at the top of the range. The final price depends on implant size, surgeon, facility, and any ancillary procedures. Always request an itemised quote that includes the revision/removal policy. Figures are indicative; confirm at consultation.
How common are complications and removals with Penuma?
They are not negligible. Peer-reviewed series report seroma in roughly 5% of cases in some series (up to about 12% requiring drainage in a recent two-approach study), infection around 1-3%, and device removal in roughly 6-21% of patients depending on surgical approach (lower with the lateral scrotal technique, higher with the older infrapubic approach). A separate single-center series reported about 12% removal. Choosing an experienced surgeon reduces but does not eliminate these risks.
Is Penuma reversible?
It can be removed, but removal is a second surgery, not a clean undo. It can leave scar tissue, skin changes, or cosmetic deformity (including post-removal curvature in some reported cases), and it carries its own recovery time and cost. Factor a possible removal into your decision and ask the clinic for the removal price in writing.
Will Penuma look and feel natural?
Many men are satisfied with the look and feel, but patient-reported outcomes are mixed. Some report palpable implant edges, firmness, or changes in sensation. A natural result is the goal, not a guarantee, and it depends heavily on surgical technique and your anatomy.
When can I have sex again after Penuma?
Most protocols restrict sexual activity for at least 6-8 weeks and require surgeon clearance first, consistent with general penile-implant recovery guidance. The final aesthetic result settles around 3-4 months.
How does Penuma compare to Himplant?
Both are cosmetic silicone implants placed under the penile skin for flaccid girth and length, with similar recovery and a similar premium price range in Bangkok. They differ in implant design and surgeon availability. Neither treats ED or reliably increases erect length. A consultation can determine which device and surgeon best fit your anatomy and goals.
Who should not get Penuma?
Penuma is not appropriate for men with active infection, uncontrolled diabetes, current nicotine use, bleeding or clotting disorders, significant Peyronie's curvature, certain prior penile or groin surgeries, or features of body dysmorphic disorder. It is also not for men whose main goal is treating ED or gaining erect length. A full medical evaluation is required to confirm candidacy.
