If you are considering permanent penile enlargement, two of the most recognized silicone implants available today for penile girth enhancement are Peniflex and Penuma (Himplant).
Both implants are designed to increase penile girth and can provide a noticeable aesthetic improvement in both the flaccid and erect states.
Modern penile enhancement surgery is not only about increasing size. It can also help improve self-confidence, body image, and reduce the psychological discomfort that many men experience because of concerns about penile size.
It is important to understand that there is no universal solution that is ideal for every patient. Some men are primarily interested in maximizing size during erection and improving their sexual experience. Others place greater value on the appearance of the penis in everyday situations, such as in the locker room, swimming pool, sauna, or while changing clothes.
For this reason, the choice between Peniflex and Penuma should always be made individually after consultation with an experienced andrology surgeon.
Over the past few years, interest in penile enlargement surgery has grown significantly. More and more men seek consultation not only for functional reasons but also to improve their self-confidence and overall quality of life.
Today, Peniflex and Penuma (Himplant) are among the best-known solutions for permanent penile girth enhancement.
Both implants can provide a substantial increase in penile size without affecting erectile function or penile sensation when the procedure is performed correctly and appropriate surgical protocols are followed.
Peniflex is a soft silicone implant featuring perforations designed to promote tissue integration and lymphatic drainage. The implant is placed beneath the penile skin along the shaft of the penis, over the corpora cavernosa.
The Peniflex design aims to minimize pressure on surrounding tissues while providing a natural appearance and feel after surgery.
According to published data, Peniflex can increase penile girth by approximately 4–5 cm. In addition, when combined with a dedicated postoperative traction program, it may also contribute to an increase in erect penile length.
Penuma, now also known as Himplant, is one of the most recognized penile enhancement implants in the world.
The implant has gained widespread popularity in the United States, the Middle East, and other regions due to its ability to provide substantial penile girth enhancement and a pronounced aesthetic improvement in the flaccid state.
According to current clinical data, Penuma can increase penile girth by approximately 5–8 cm and may increase flaccid penile length by approximately 3–4 cm.
For this reason, many patients choose Penuma when their primary goal is to achieve the most noticeable visual enlargement, even when the penis is not erect.
Many men consider the improved appearance of the flaccid penis to be a significant benefit, helping them feel more confident in situations such as locker rooms, swimming pools, saunas, or intimate encounters.
As a fibrous capsule forms around the implant, the increased flaccid size is maintained over time. For example, a patient with a flaccid penile length of 7 cm and circumference of 9 cm, and an erect length of 14 cm with a circumference of 12 cm, may achieve postoperative dimensions of approximately 10–11 cm in flaccid length and 14–17 cm in flaccid circumference. During erection, penile girth may increase to approximately 17–20 cm.
Penuma is therefore particularly suitable for men whose primary goal is to increase the size and visual presence of the penis in the flaccid state and improve confidence in everyday situations.
Patients considering Peniflex or Penuma implantation must be circumcised prior to surgery.
If circumcision has not been performed previously, it is recommended at least 2 months before the procedure. This allows adequate healing and helps reduce the risk of postoperative complications.
Both Peniflex and Penuma implantation can be combined with ligamentotomy (surgical release of the suspensory ligament of the penis). This procedure may provide an additional increase in penile length of approximately 2–2.5 cm.
Suitable candidates for implantation typically include men who:
Are dissatisfied with their penile girth;
Desire a permanent enlargement solution;
Have realistic expectations regarding the outcome of surgery;
Do not have severe uncontrolled medical conditions;
Are willing to follow postoperative instructions and attend follow-up appointments.
Peniflex is often considered by patients who place particular importance on penile size during erection.
Due to its design characteristics and the required postoperative traction program, Peniflex can not only increase penile girth but may also help preserve or enhance erect penile length.
Penuma is more commonly chosen by men seeking the most significant increase in penile girth and the most noticeable visual enhancement in the flaccid state.
According to current clinical data, Penuma can provide an increase in penile girth of approximately 5–8 cm and an increase in flaccid penile length of approximately 3–4 cm.
For this reason, Penuma has become a popular option among patients who value not only improvements during sexual activity but also a more impressive appearance of the penis in everyday situations.
There are several situations in which Peniflex or Penuma implantation is not recommended.
Absolute contraindications include:
Previous penile lipofilling (fat transfer);
The presence of permanent or long-lasting fillers (PMMA, silicone, and other non-absorbable materials);
Active infection or inflammatory conditions;
Severe psychiatric disorders;
Significant penile curvature greater than 30° without prior correction.
Special consideration should be given to patients who have previously undergone penile enlargement procedures using injectable materials.
Following hyaluronic acid injections, implantation is generally possible no sooner than 12 months after the product has completely dissolved.
After the use of permanent or long-lasting fillers, the risk of complications increases significantly. For this reason, penile implant surgery is generally not recommended in such cases.
The Penuma implant is typically inserted through an incision made in the scrotal area near the base of the penis.
As with Peniflex implantation, the procedure may be combined with ligamentotomy to provide additional flaccid penile length enhancement.
Following implantation, a fibrous capsule gradually forms around the device, helping to maintain the achieved enlargement over time.
One of the main advantages of Penuma is its ability to provide a more substantial increase in penile girth compared to most other surgical penile enhancement procedures.
Recovery after Peniflex or Penuma implantation is generally straightforward and relatively quick.
Typical recovery milestones include:
Return to normal daily activities: after 3/4 days;
Gym workouts, swimming pools, and saunas: after 2 weeks;
Sexual intercourse: after 5/6 weeks;
Oral sex: after 2 weeks.
Final tissue healing and stabilization of the result typically take several months.
Patients typically arrive at the clinic one day before surgery for a pre-anesthesia consultation and the required laboratory tests.
To minimize waiting time at the clinic, we recommend completing the blood tests in advance and sending the results before arrival.
The procedure itself usually takes approximately 60–90 minutes.
Patients generally stay in the clinic for one night after surgery.
The following day, a dressing change is performed and the patient is discharged.
For international patients, we recommend remaining in the city for an additional 3–4 days after discharge.
A surgical drain is placed during the procedure and is typically removed on postoperative day 4–5.
The most common postoperative occurrence following Peniflex or Penuma implantation is temporary fluid accumulation around the implant, known as a seroma.
Seroma formation is a normal part of the healing process and typically decreases gradually as the fibrous capsule develops around the implant.
If necessary, seroma aspiration can be performed under local anesthesia. The procedure takes only a few minutes and may help accelerate recovery.
As with any surgical procedure, potential complications may include:
Swelling;
Hematoma formation;
Temporary discomfort;
Inflammatory complications;
The need for revision or corrective procedures.
The risk of complications can be significantly reduced through appropriate implant selection, meticulous surgical technique, and careful adherence to all postoperative instructions.
The surgeon’s experience and regular postoperative follow-up also play an important role in achieving the best possible outcome.
Following implantation, patients are prescribed a standard postoperative treatment regimen, which typically includes:
Antibiotics for 2 weeks;
Pain medication for approximately 1 week;
Anti-swelling therapy for up to 2 weeks.
During the first two weeks, regular penile dressing changes are recommended to reduce swelling and promote proper healing.
Beginning in the third week, gentle manual stretching of the penis is recommended, preferably after urination.
Starting from the fourth week, patients are advised to use a penile extender or traction device that provides continuous, moderate tissue stretching.
Postoperative traction therapy is an important part of recovery after Peniflex implantation. It helps promote the formation of a flexible capsule around the implant and assists in preserving penile length.
In some cases, consistent use of the traction program may provide an additional increase in penile length of approximately 1–2 cm.
Following Penuma implantation, patients should carefully follow their surgeon’s recommendations regarding physical activity restrictions, wound care, and the timing of resuming sexual activity.
During the first few weeks after surgery, it is important to avoid excessive physical strain, trauma to the surgical area, and premature return to sexual activity.
Regular follow-up appointments allow the healing process to be monitored and the recovery protocol to be adjusted when necessary.
Regardless of the implant chosen, the quality of the final result depends not only on the surgery itself but also on proper postoperative care.
Timely follow-up visits, appropriate wound care, and adherence to your surgeon’s recommendations help promote faster recovery and reduce the risk of complications.

There is no single implant that can be considered the best choice for every patient.
Peniflex and Penuma have different design characteristics and may be better suited to different patient goals and expectations.
For some men, the priority is maximizing penile size during erection and enhancing sexual performance. For others, the primary goal is achieving the greatest possible increase in penile girth and overall size in the flaccid state.
For this reason, the final treatment decision should always be based on the patient’s anatomy, aesthetic goals, and the surgeon’s recommendations.
In some cases, a consultation may reveal that implants are not the most appropriate option. Alternative penile enhancement procedures, including modern fillers or combination treatments, may provide better results for certain patients.
Before making a decision, we recommend scheduling a personal consultation and providing photographs for a preliminary assessment of your suitability for the procedure.
