What Is the Penuma Implant?

Penuma, also sold under the brand name Himplant, describes a soft, crescent-shaped silicone implant. Surgeons place it beneath the skin of the penis to increase girth and flaccid length. A US manufacturer developed it, and it holds FDA 510(k) clearance. This makes it the first implant of its kind cleared in the United States for cosmetic enhancement.

Many patients researching penile girth options come across Penuma online. For this reason, we want to explain honestly what it is, and why our Istanbul clinic takes a different approach.

Unlike traditional penile prostheses used for erectile dysfunction, Penuma serves a purely cosmetic purpose. It does not treat any underlying medical condition, and men with normal erectile function are the typical candidates. This distinction matters, since the risk-benefit calculation for a purely cosmetic device differs meaningfully from one addressing a genuine functional problem requiring treatment.

Typical Penuma Implant Results Reported

Manufacturer-reported outcomes describe average girth gains of roughly 1.5 to 2 inches. In addition, patients see a modest flaccid length increase of about 0.5 to 1 inch. Results depend on implant size and individual anatomy. As with any implant, therefore, individual results vary, and not every patient achieves the described average.

Worth noting, these figures come primarily from manufacturer-reported data rather than large, independent, peer-reviewed studies. This does not necessarily mean the numbers lack accuracy, but it does mean patients should treat them as a general guide rather than a guaranteed outcome specific to their own anatomy.

Peniflex®: Our CE-Certified Alternative

Instead of Penuma, SafeFill Clinic offers Peniflex®. This silicone girth implant carries full CE certification for use in Turkey and across Europe. Peniflex® uses softer silicone, rounded corners, and small perforations for lymphatic drainage. This design reports a protrusion rate of roughly 3%, compared with considerably higher published rates for Penuma.

For a complete breakdown of the Peniflex® procedure, benefits, and pricing, therefore, see our dedicated Peniflex® Penile Implant guide.

Beyond the lower protrusion rate, Peniflex® also benefits from a design specifically refined based on real-world outcome data collected after the original Penuma-style devices entered the market. In effect, later-generation devices like Peniflex® had the advantage of learning from earlier design limitations, reflected directly in its published safety profile.

Risks Worth Understanding, Regardless of Device

Any silicone girth implant, whichever brand, carries potential risks. These include infection, scarring, implant malposition or protrusion, and changes in sensation. A thorough consultation, therefore, should always cover these risks honestly, alongside realistic expectations.

Infection risk peaks in the first few weeks after surgery, which is why Dr. Tas emphasizes strict wound care during this window specifically. Sensation changes, while uncommon, typically involve mild numbness near the incision rather than a loss of overall sexual function, and this usually resolves as healing progresses over the following months.

We recommend a second opinion, in addition, whenever you feel uncertain about any surgical decision. This holds true regardless of where you ultimately choose to have the procedure.

Since this device sits beneath the skin rather than replacing existing tissue, some patients also ask about long-term maintenance. Generally, once healing completes, the implant requires no ongoing care beyond normal hygiene, and most men describe forgetting about its presence entirely within a few months of recovery.
