A penis prosthesis , or implant penis, is a medical device implanted in the corpora cavernosa of the penis during a surgical procedure. This tool is indicated for use in men with organic impotence or treatment-resistant or erectile dysfunction that results from various physical conditions such as cardiovascular disease, diabetes, pelvic trauma, Peyronie's disease, or as a result of prostate cancer treatment. Less commonly, penile prostheses can also be used in the final stages of plastic surgery to improve the operation of male and female rejuvenation surgeries during the total phalloplasty for adult and adult patients requiring male genital modification.

Reasons for use
Penile implants are one of the treatment options available to individuals who can not achieve or maintain an adequate erection for successful sexual intercourse or penetration. Its primary use is for men with erectile dysfunction of vascular conditions (cardiovascular disease, high blood pressure, diabetes), congenital anomalies, iatrogenic, penile or accidental pelvic injury, Peyronie's disease, or as a result of prostate cancer treatment. These implants are usually considered when less invasive medical treatments such as oral medications (PDE5: Viagra, Levitra, Cialis inhibitors), penile injections, or vacuum erection devices are unsuccessful, give unsatisfactory results, or are contraindicated. For example, many drugs used to treat erectile dysfunction are not suitable for patients with heart problems and may interfere with other drugs.
Sometimes a penile prosthesis is implanted during surgery to alter, build or reconstruct the penis in phalloplasty. The British Journal of Urology International reported that unlike metoidioplasty for women and men sexual reassignment of patients, which can cause a long but narrow penis, the total formation of neoplallus phalloplasty currently using the latisimus doris muskulokutan flap can produce a long and large penis. which allows safe insertion of all types of penile prostheses.
This same technique allows male victims from serious injury to an iatrogenic penis, accidental accidents or intentional penile injury (or even total deadlock) caused by accident, child abuse or self-mutilation to have a penis suitable for implantation of the prosthesis penis enabling successful sexual intercourse.
In some cases of genital reconstruction surgery, semirigid prosthesis implantation is recommended for three months after the total phalloplasty to prevent phallic retraction. This can be replaced later with the inflatable.

Device type
There are two main types of penile prosthesis: semirigid devices that can not be duplicated, and blowing devices. Semirigid tools that can not be duplicated, consisting of a rod implanted into the penis erection booth and can be bent into the position necessary for sexual penetration. With this type of implant, the penis is always semi-rigid and therefore may be difficult to conceal.
Hydraulics, blowing prostheses also exist and were first described in 1973 by Brantley Scott et al. The salt-containing apparatus comprises the inflatable cylinders placed in the penile installation chambers, a pump placed in the scrotum for patient-activated inflation/deflation, and a reservoir placed in the stomach that stores the liquid. The device is pumped by pressing the pump several times to transfer fluid from the reservoir to the chamber on the penis. After intercourse, the valve next to the pump is operated manually, allowing fluid to be removed from the penis (not instantly, squeezing the penis may be necessary), causing the penis to return to a soft or semi-soft condition. Nearly all embedded penile prosthesis devices work satisfactorily for a decade or more before they need to be replaced. Some surgeons recommend this because it argues that they are more easily hidden and provide the highest patient/partner rate of satisfaction.
Benefits
- Low mechanical failure rate: most often the inability to deflate the penis due to pump failure; less frequent inability to inflate the prosthesis; and sometimes disconnection or failure of reservoirs.
- IPP (Inflatable Penile Prostheses) are easily hidden under clothing including swimwear or jeans. Erection can be maintained for as long as necessary, or as long as desired without serious serious complications of organic priapism.
- Psychological and emotional health is enhanced in the proportion of men undergoing implant surgery. Several studies have shown high levels of patient satisfaction, in part due to technological improvements in the prosthesis itself, better surgical techniques make the procedure less painful, and patient expectations more plausible.
- Device inflation can be solved quietly.
Loss
- The gland is not enlarged and the sexual penetration may be strange. The penis may also not be as strong as a natural erection.
- Some models are not easy to deflate; some level of manual dexterity is required to operate one inflatable model, making it inappropriate for men with other neurological disorders such as stroke or Parkinson's disease.
- The penis may not be entirely soft, depending on the prosthesis model (most commonly seen in semi-rigid or soft implants).
- Many men lose lengths between 1-2 cm (0.25 to 0.75 inches).
- After surgery, the patient experiences one to two weeks of moderate or sometimes severe pain, usually controlled with analgesics. This is most often due to swelling of the scrotum, which can sometimes be very deep. Normal sexual intercourse can be continued six to eight weeks after surgery, waiting for permission from the surgeon.
- Not all men report complete satisfaction with the prosthesis.
- Some studies show a 70% or less partner's satisfaction rate, because, some research suggests, high or unreasonable expectations. Many surgeons now recommend that both partners be counseled before surgery on outcomes and expectations.
- Device inflation is not instantaneous.
- It is difficult to hide the prosthesis because the hard and irregularly shaped scrotum components. A scrotal partner will notice this.
- Manual stimulation can be painful.
- There is a 2-10% complication rate, mainly due to infection or device failure. Complications include: uncontrolled hemorrhage after surgery may cause reoperation, scar tissue formation, erosion (tissue around the implant may be damaged) requiring removal or mechanical failure resulting in re-surgery and lifting.
