The Penuma implant is a cosmetic surgical option designed for permanent penile enhancement. The procedure involves surgically placing a device beneath the skin to increase the physical dimensions of the penis. This technique is intended for aesthetic modification and is distinct from procedures that treat medical conditions like erectile dysfunction. This article explores the specifics of the procedure, focusing on the potential for an increase in erect length.
Understanding the Penuma Implant
The Penuma implant is a soft, medical-grade silicone sleeve custom-contoured to the shape of the penis. It is surgically placed beneath the skin layers of the shaft, positioned above the erectile chambers. The device is solid and functions as a non-inflatable covering.
The primary mechanism for enhancement is the physical stretching of the surrounding tissue and skin, resulting in a noticeable increase in girth. This augmentation is present whether the penis is flaccid or erect. The implant is available in various sizes (large, extra-large, and extra-extra-large) and is trimmed by the surgeon to ensure a personalized fit.
The device holds FDA clearance for the cosmetic correction of soft tissue deformities, making it the only silicone sleeve implant cleared by the U.S. Food and Drug Administration for aesthetic penile enhancement. This regulatory status distinguishes it from other non-surgical methods. The design focuses on adding volume and contour to the shaft, which can also help address conditions like a retractile penis.
Anticipated Outcomes on Erect Length
The core physiological effect of the Penuma implant is primarily an increase in girth, or circumference, consistently reported across clinical studies. The implant adds a layer of bulk beneath the skin of the shaft. This mechanical addition of volume results in significant circumference gains, often reported in the range of 3.0 to 4.1 centimeters, representing an increase of approximately 32% to 37% in mid-shaft girth.
The implant is also linked to a substantial increase in the flaccid length of the penis. Studies indicate the average gain in flaccid length is approximately 3.8 to 4.9 centimeters (1.5 to 1.9 inches), representing a gain of over 50%. This flaccid length increase occurs due to the constant outward stretching of the penile skin and tissues by the underlying implant.
The gain in true erect length is a more complex matter. The implant wraps around the penis but does not alter the fundamental structure of the corpora cavernosa, the chambers that fill with blood to create an erection. Consequently, the implant does not physically increase the maximum expansion capability of the erectile tissue.
While some patients subjectively report increased erect length, or the added girth may make the erect penis appear longer, the consensus among many surgeons is that the implant does not provide a true increase in the maximum measured erect length. Any perceived lengthening during erection is often an indirect effect of the implant’s volume or the prior stretching of the skin. The most dramatic and measurable length change will be observed when the penis is flaccid.
The Surgical Process and Post-Procedure Recovery
The implantation of the Penuma device is an outpatient procedure typically performed under general anesthesia, though sedation may also be used. The surgeon makes a small incision, usually on the scrotum, to access the penile shaft. The implant is then carefully inserted beneath the subcutaneous tissue and positioned over the erectile bodies.
The procedure generally takes less than an hour, allowing patients to return home the same day. Post-operatively, a surgical drain is often placed to manage fluid accumulation and is typically removed within the first two days. Patients may be instructed to apply a topical ointment for several weeks to promote blood flow and aid in healing.
Initial recovery involves managing expected swelling and bruising, which can affect the penis and surrounding areas for one to two weeks. Patients are advised to wear a scrotal support garment and rest with the scrotum elevated to minimize swelling. Pain and soreness are common for the first couple of weeks, managed with prescription medication.
A strict recovery timeline is necessary to prevent complications. Strenuous activities, including heavy lifting and exercise, are restricted for six to eight weeks. Patients must abstain from all forms of sexual activity, including masturbation, for a minimum of six to eight weeks to allow the tissues to fully heal and secure the implant.
Managing Expectations and Potential Complications
Patient satisfaction with the Penuma implant is generally reported to be high, often linked to a significant increase in self-confidence and satisfaction with penile appearance. This improvement stems from the substantial cosmetic change, particularly the increase in girth and flaccid length. However, patients must have a realistic understanding of potential adverse events before proceeding with surgery.
As with any implant surgery, specific complications exist. The most common is seroma formation, where fluid collects beneath the skin, sometimes requiring aspiration or drainage. Less frequent but more serious complications include infection, which typically necessitates the removal of the device to resolve the issue.
Other considerations include the risk of implant displacement, erosion through the skin, or persistent flaring near the head of the penis. Temporary changes in penile sensation, such as hypersensitivity or numbness, can occur due to skin stretching but usually resolve as the tissue adapts. If the implant is removed, capsular contraction can occur, potentially leading to penile shortening or curvature that may require further corrective surgery.
The surgeon’s pre-surgical consultation is necessary for determining patient eligibility and ensuring a thorough discussion of cosmetic goals and the long-term safety profile. Patients with pre-existing medical conditions may be excluded. Adherence to all pre- and post-operative instructions helps minimize the risk of adverse outcomes.
