Procedure comparison
Himplant vs HA Fillers
An objective educational comparison. Neither option is universally superior; the most appropriate option depends on anatomy, goals, risk tolerance, budget, and physician evaluation.
Himplant / Penuma
- Implant-based
- Surgical
- Longer recovery
- FDA 510(k)-cleared device
- Intended for selected patients seeking implant-based girth enhancement
- Risks include infection, implant visibility, migration, seroma, dissatisfaction, revision, or removal
HA Fillers
- Non-surgical
- Temporary
- Often performed in-office
- Repeat treatments may be required
- Results vary
- Risks include swelling, irregularity, vascular events, infection, dissatisfaction, or need for correction
The most appropriate option depends on anatomy, goals, risk tolerance, budget, and physician evaluation.

Himplant® — manufacturer attribution & risk disclosure
Manufacturer
Himplant® (also marketed in some markets as Penuma®) is a medical-grade silicone subcutaneous penile implant developed and distributed by International Medical Devices, Inc. (IMD) / Augmenta. Surgeons must be trained and authorized by the manufacturer to perform the procedure. Patients should confirm directly with the manufacturer or treating surgeon whether a given clinician is a trained provider.
Regulatory status
Penuma® received U.S. FDA 510(k) clearance for cosmetic correction of soft-tissue deformities of the penis. 510(k) clearance is not the same as FDA approval and does not certify clinical efficacy for cosmetic enhancement. Regulatory status of Himplant® varies by country; patients receiving care outside the United States should confirm local regulatory clearance directly with their surgeon.
Material risks patients should understand before consenting
- Infection, including implant infection that may require removal.
- Seroma (fluid collection) and hematoma in the first weeks post-op.
- Implant migration, palpability, contour irregularity, or asymmetry.
- Penile sensory changes — temporary or, less commonly, persistent.
- Erectile or ejaculatory function changes; the implant does not treat erectile dysfunction.
- Scar tissue (capsular contracture-type response) and skin-related complications.
- Implant explantation, revision surgery, or reoperation.
- Outcome variability — published satisfaction data reflect selected cohorts, not all patients.
