Procedure comparison
Himplant vs Fat Transfer
An objective educational comparison. Both options have risks and limitations. A qualified physician must evaluate candidacy.
Himplant / Penuma
- Silicone subcutaneous implant
- Surgical procedure
- Device-based girth enhancement
- Recovery required
- May be removable or revised in selected situations
Fat Transfer (Lipofilling)
- Uses the patient's own fat
- Surgical harvesting and injection
- Volume retention varies
- Repeat treatments may be required
- Irregularity, asymmetry, and resorption are possible
Both options have risks and limitations. A qualified physician must evaluate candidacy.
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.
