Penile Prosthesis (Penile Implant): Types, How It Works, and Benefits

Penile prosthesis surgery is a surgical procedure that provides a permanent and effective solution in the treatment of advanced erectile dysfunction. In patients who do not respond to medication and other treatments, controlled erection is achieved through prostheses placed inside the penis, and sexual function is restored.

The types of penile prostheses and application techniques are determined according to the patient’s anatomical structure and needs. There are two main types of prostheses, inflatable and semi-rigid, and the surgical procedure is generally performed under general or spinal anesthesia. The operation time varies between an average of 1–2 hours.

The recovery process after penile prosthesis surgery requires careful follow-up and compliance with hygiene rules. While patients usually return to their normal lives within a few weeks, the time to start sexual activity is planned according to the physician’s recommendation. Antibiotic treatment may be applied to reduce the risk of infection.

The advantages and possible risks of penile prosthesis surgery are evaluated in detail during the patient information process. This method, which has a high patient satisfaction rate, provides long-term success with correct patient selection. Rarely, complications such as mechanical failure or infection may occur.

What Is Penile Prosthesis Surgery?

Penile prosthesis surgery is a surgical procedure applied as a permanent and effective treatment option in men with erectile dysfunction. The main purpose of this surgery is to provide a natural-looking and sufficient erection through special prostheses placed inside the penis in cases of erection problems where medication or other treatment methods do not provide successful results. Penile prosthesis is also popularly known as a “happiness rod” and helps restore sexual life to a healthy state.

This surgery significantly improves quality of life, especially in men with long-term erectile dysfunction. The applied prosthesis is placed into the two spongy tissues inside the penis (corpus cavernosum). Thanks to these prostheses, the person can achieve sufficient rigidity for sexual intercourse manually or through an inflation mechanism. Penile prosthesis surgery is one of the safe surgical procedures performed today with high success rates.

In Which Cases Is Penile Prosthesis Preferred?

Penile prosthesis is generally preferred in patients in whom medication, injection, or vacuum treatments do not produce results. This surgical method is applied especially in erectile dysfunctions caused by vascular, nerve, or hormonal factors. Diabetic patients, those with atherosclerosis, those who have had spinal cord injury, or men who experience loss of erection after prostate surgery may be candidates for this surgery.

Penile prosthesis not only solves a physical problem; it also restores self-confidence psychologically. This is because erection problems often negatively affect the perception of masculinity and the emotional bond with the partner. Therefore, the prosthesis provides comprehensive improvement both physically and psychologically.

What Is Erectile Dysfunction and When Does Surgery Come into Consideration?

Erectile dysfunction, meaning erection problem, is the inability to achieve or maintain the rigidity required for sexual intercourse due to insufficient blood flow to the penis. While this problem may sometimes be temporary, it requires treatment when it becomes chronic. Age, diabetes, hypertension, heart disease, smoking, stress, and depression are among the most common causes.

Surgical treatment comes into consideration when no response is obtained from medication treatment or other methods. Especially in cases where blood vessels are permanently damaged, penile prosthesis surgery provides a permanent solution. Today, these operations performed with modern surgical techniques provide both safe and aesthetically natural results.

What Are the Types of Penile Prostheses?

Penile prostheses are basically evaluated in two main groups: bendable (malleable) prostheses and inflatable prostheses. Bendable prostheses have a continuously semi-rigid structure and can be brought to the desired position by hand. Inflatable prostheses usually consist of two or three parts; the user hardens the penis by squeezing the pump placed inside the scrotum and deflates it with the same pump after intercourse.

Both types of prostheses have advantages. Bendable models offer more economical and simple use, while inflatable prostheses are more successful in terms of natural appearance and sensation. Prosthesis selection is determined according to the patient’s age, manual dexterity, health condition, and expectations.

Differences Between Inflatable Penile Prosthesis and Bendable Prosthesis

Inflatable prostheses provide a more natural erection appearance and feeling. In these models, it is possible to transition between the natural flaccid and rigid state of the penis. In bendable prostheses, the penis always remains semi-rigid and the risk of being noticed under clothing is slightly higher.

Inflatable prostheses are aesthetically and functionally more comfortable, but they are surgically more complex and higher in cost.

Bendable prostheses are preferred in elderly patients or patients with limited manual dexterity. The operation time is shorter and the risk of infection is lower. Today, most patients prefer inflatable prostheses because of their aesthetic and natural appearance advantage.

Who Is Suitable for Penile Prosthesis Surgery?

Penile prosthesis surgery is a suitable option for men whose erectile dysfunction cannot be resolved with medication or other treatment methods. Especially diabetic patients, those with atherosclerosis, those with spinal cord injury, individuals who have received radiotherapy to the pelvic region, and men who have lost their erection ability after prostate surgery may be candidates for this surgery. In addition, penile prosthesis surgery gives more effective results in those who have erectile dysfunction due to physiological rather than psychological causes.

Before surgery, the patient’s general health condition is evaluated. Heart, blood pressure, diabetes, liver, and kidney functions must be at a level that can tolerate the surgery. Being psychologically ready for the surgery is also important because the postoperative period requires correct use of the device, patience, and a conscious approach.

Therefore, doctor-patient communication must be very strong before surgery, and all stages of the operation should be explained to the patient in detail.

Penile Prosthesis in Erectile Dysfunction After Prostate Surgery

In some men, erectile dysfunction may become permanent after radical prostatectomy surgery performed in the treatment of prostate cancer. This condition results from damage to the nerves or vessels during surgery. Medication treatments and injections are usually tried in the first stage, but when they are not effective, penile prosthesis provides a permanent solution.

Penile prosthesis applications after prostate surgery provide very successful results, especially in cases where the nerves are damaged. After the prosthesis is placed, patients can achieve a natural erection and return to their sexual lives normally. This situation brings not only physical but also emotional recovery.

Expert urologists recommend inflatable models in prosthesis selection for men who have undergone prostate surgery because these prostheses offer a natural appearance and are not noticeable in daily life. In addition, modern models have antibacterial coatings that minimize the risk of infection.

How Is Preparation Before Penile Prosthesis Surgery?

Before penile prosthesis surgery, the patient must undergo a detailed evaluation. First, a physical examination is performed, and the vascular structure, genital anatomy, and general health condition are examined. Then routine tests such as laboratory tests, ECG, and chest X-ray are completed. To reduce the risk of infection, urinalysis is performed, and if there is an existing infection, surgery is not performed before it is treated.

Blood-thinning medications may need to be stopped a few days before surgery. In diabetic patients, blood sugar levels should be brought under control because high blood sugar may increase the risk of infection. In addition, before surgery, the patient is informed about the type of prosthesis to be used and expectations are evaluated.

On the morning of surgery, the patient usually comes to the hospital fasting. If necessary, an intravenous line is opened and antibiotics are started. This entire preparation process is very important for the operation to proceed safely and smoothly.

How Is Penile Prosthesis Surgery Performed?

Penile prosthesis surgery is performed under general or spinal anesthesia. It is a procedure that lasts an average of 1 to 1.5 hours. During the surgery, a small incision is made at the base of the penis or in the scrotum area. Through this incision, the prosthesis is placed into the spongy tissues inside the penis.

In inflatable prostheses, additionally, a fluid reservoir is placed inside the abdomen or in the groin area. During sexual intercourse, this reservoir sends fluid to the cylinders with the help of the pump and provides erection. After the surgery, the incision is closed aesthetically and usually no visible scar remains.

In operations performed with modern surgical techniques, the risk of infection is quite low. Since the prostheses used are produced from biocompatible biomaterials, the possibility of allergic reaction is very low. When the surgical team is experienced, the success rate is over 95%.

How Long Does Penile Prosthesis Surgery Take?

Penile prosthesis surgery is usually completed between 60 and 90 minutes. The duration of the surgery may vary depending on the patient’s anatomical structure, the type of prosthesis used, and any additional medical conditions. While the duration is shorter in patients receiving a prosthesis for the first time, the procedure may take slightly longer in patients who have previously had a prosthesis placed and removed.

After the surgery, the patient is usually discharged on the same day or the next day. However, in some cases, the patient may be kept under observation in the hospital for one night. During this period, the patient’s pain is controlled, the urinary catheter is removed, and follow-up is performed in terms of infection risk.

How Is Anesthesia Applied in Penile Prosthesis Surgery?

During penile prosthesis surgery, spinal anesthesia (numbing from the waist down) or general anesthesia is generally preferred. Spinal anesthesia is the numbing of the patient while consciousness remains open but no pain is felt. This method ensures less postoperative pain.

In some cases, especially in those with additional diseases, general anesthesia may be safer. The anesthesiologist and urologist decide together which type of anesthesia will be applied. During the surgery, all vital signs of the patient are continuously monitored. In this way, the operation process proceeds both safely and comfortably.

Hospital Stay After Penile Prosthesis Surgery

After surgery, patients usually stay in the hospital for 1 to 2 days. During this period, antibiotic treatment is applied, pain control is provided, and the wound site is checked regularly. The urinary catheter is usually removed the next day. When the patient can urinate on their own, they become suitable for discharge.

During the hospital stay, the patient is given basic information about how the prosthesis will be used. However, generally 4–6 weeks are waited for the prosthesis to be activated. During this period, wound healing is completed and the risk of infection decreases. The patient’s first follow-up after discharge is usually performed one week later.

Recovery Process After Penile Prosthesis Surgery

Although the recovery process after penile prosthesis surgery varies from person to person, it generally lasts 4 to 6 weeks. Swelling, edema, and mild pain may be felt in the first few days. These conditions are normal and are usually easily controlled with painkiller medications.

Rest is recommended during the first week, and heavy physical activities should be avoided. At the end of the period recommended by the doctor, usually in the 6th week, the prosthesis is activated and the patient can have sexual intercourse. In inflatable prostheses, during this process, the doctor teaches in detail how to use the pump.

When recovery is complete, the prosthesis becomes part of the body and the person continues daily life completely normally. The prosthesis is not noticeable from the outside in terms of appearance and provides a natural erection feeling.

How Long Do Pain and Edema Last After Penile Prosthesis Surgery?

Pain and edema are normal especially during the first 3–5 days after surgery. During this period, when prescribed painkillers are used regularly, complaints decrease rapidly. In inflatable prostheses, it may take a few weeks for the tissues in the area where the prosthesis is placed to adapt to the new structure.

Edema usually resolves largely within 10 days. Ice application, rest, and keeping the legs slightly elevated accelerate recovery. If the pain lasts longer than expected or if symptoms such as redness at the wound site and fever occur, a doctor must definitely be consulted.

Infection Risk and Prevention After Penile Prosthesis Surgery

One of the most important complications after penile prosthesis surgery is infection. However, thanks to modern surgical techniques, sterile operating room conditions, and the use of prostheses with antibacterial coating, this risk has decreased considerably. The infection rate has fallen below 1% in the practices of experienced surgeons.

Among the most common factors causing infection are diabetes, obesity, smoking, and insufficient hygiene. Therefore, it is very important to bring these risk factors under control before surgery. Patients receive antibiotic treatment before and after surgery.

Keeping the wound site clean, changing dressings as recommended by the doctor, and avoiding tight clothing that creates pressure on the prosthesis area reduce the risk of infection. If symptoms such as fever, chills, severe pain, or discharge from the wound site occur after surgery, a doctor should be consulted without delay. Early detection of infection significantly increases the success rate of treatment.

When Can Sexual Intercourse Be Started with a Penile Prosthesis?

After penile prosthesis surgery, it is generally necessary to wait 4 to 6 weeks before having sexual intercourse. This period is critical for the tissues to heal completely and the prosthesis to stabilize in place. Having intercourse before wound healing is complete may increase the risk of infection or cause the prosthesis to move out of place.

The doctor gives permission to the patient according to the healing status at the first examination. If an inflatable prosthesis has been inserted, the patient is taught in detail how to inflate and deflate the prosthesis during this period. The first use is usually performed under the doctor’s supervision.

After this process is completed, the patient can have sexual intercourse as if achieving a natural erection. The prosthesis also creates a natural feeling for the partner and the level of sexual satisfaction is high.

Does a Penile Prosthesis Affect Sexual Pleasure and Orgasm?

Penile prosthesis surgery only corrects the erection mechanism; it does not directly affect the feeling of orgasm or sexual desire. In other words, a man with a prosthesis can naturally experience sexual pleasure and orgasm. This surgery does not impair the sensation of the penis, the ability to ejaculate, or sexual harmony with the partner.

The psychological dimension of sexual life is also quite important. Many men who regain erection thanks to the prosthesis state that their self-confidence increases and they have a more satisfying relationship with their partner. This also improves overall quality of life.

In short, penile prosthesis surgery restores the natural functions of masculinity; it has no negative effect on pleasure, satisfaction, and emotional bond.

Does a Penile Prosthesis Affect Penis Size?

Penile prosthesis surgery does not increase penis length; however, it restores the lost ability to achieve erection. Some patients may think that the penis has shortened because the erectile dysfunction has continued for a long time. This condition is generally related to reduced blood flow and loss of tissue elasticity.

After prosthesis surgery, when the penis regains its former fullness and erect position, patients are generally satisfied. In inflatable prostheses, the rigidity and fullness obtained during erection provide a natural appearance. Selecting the prosthesis in the correct measurements is important for preserving penis length.

Therefore, before surgery, the doctor determines the appropriate size prosthesis for the patient and measures during surgery to achieve the most natural result.

Is a Penile Prosthesis Permanent, and How Long Does It Last?

Penile prostheses are permanent devices, but as with every mechanical system, they have a certain service life. The average life of modern prostheses produced today varies between 12 and 20 years. This period may vary depending on the type of prosthesis, frequency of use, and the patient’s lifestyle.

Bendable prostheses are generally more durable because they do not contain moving parts. Inflatable prostheses have pump and fluid systems, so after many years, problems such as mechanical wear or leakage may occur. However, this condition is quite rare.

To extend the life of the prosthesis, it is important to attend regular doctor check-ups, pay attention to hygiene, and use the prosthesis correctly. When the prosthesis malfunctions, only the mechanical system is replaced; generally, the entire surgical process does not need to be repeated.

Can a Penile Prosthesis Malfunction, and Is Revision Surgery Required?

Like every medical device, a penile prosthesis may mechanically fail over time. However, this rate is quite low. Especially in high-tech prostheses developed in recent years, the malfunction rate is below 3%. In case of malfunction, symptoms such as inability to achieve erection, incomplete inflation of the prosthesis, or failure of the pump to work occur.

In such cases, revision surgery is performed. The revision procedure usually takes less time and is completed by replacing only the faulty part. If the body of the prosthesis remains intact, only the pump or reservoir section may be renewed. These procedures generally enable the patient to fully regain sexual function.

When revision surgeries are performed by experienced urologists, the success rate is quite high. Therefore, there is no need to panic when the prosthesis malfunctions; modern medicine can safely solve these problems.

Things to Pay Attention to After Penile Prosthesis Surgery

The most important points to pay attention to in the postoperative period are hygiene, rest, and attending follow-up examinations regularly. Patients should avoid tight pants, heavy sports, and standing for long periods during the first few weeks.

The antibiotics prescribed by the doctor should be used regularly, wound care should not be neglected, and painkillers should be taken according to the doctor’s recommendation.

In addition, the process of inflating and deflating the prosthesis should be learned well. Difficulty during the first use is normal, but after a few attempts, the patient can easily use it on their own.

Before having sexual intercourse in the postoperative period, doctor approval must definitely be obtained. After the prosthesis fully settles in place, patients can return to their normal lives without any restrictions.

Bathing, Sports, and Return to Daily Life After Penile Prosthesis Surgery

It is not recommended to bathe during the first few days after penile prosthesis surgery. The wound site is expected to close completely. Generally, a shower can be taken after 7–10 days. However, hot water should be avoided during bathing and the area should be dried gently.

Patients can usually take light walks after 1–2 weeks, but at least 6 weeks should be waited for heavy exercises. The healing process must also be completed for activities such as swimming and cycling.

Return to daily life usually occurs within 2 weeks. After this process, the patient can completely return to work, social life, and sexual activities. After the prosthesis is inserted, the person can urinate naturally and does not feel a foreign body in the body.

Modern penile prostheses are extremely comfortable in terms of both appearance and function. Therefore, today they are accepted as the most effective solution for men with permanent erectile dysfunction.
