What are penile implants for impotence?Penile implants (often called "internal penile pumps") are one of several erectile dysfunction treatment options. The inflatable penile prosthesis is a pump system surgically placed in the penis. It allows a man to have an erection whenever he chooses. The penis does not deflate after orgasm until the man himself pushes a release valve that is part of the prosthesis. A penile prosthesis is usually used when there is a clear medical cause for the erection problem and when erections are unlikely to improve naturally. Sometimes a penile prosthesis is implanted during surgery to reconstruct the penis when scarring has caused erections to curve. A penile prosthesis changes the body permanently and so is not commonly used to treat stress-related erection problems.
The ideal penile prosthesis would produce a penis that looked and felt totally normal in the flaccid (soft) state and in the erect state. Unfortunately, no prosthesis has yet reached this standard, although many men are satisfied with those currently available. The best of today’s penile prostheses are the three-piece inflatable types. All pieces (two cylinders, a reservoir, and a pump) are placed surgically in the body. Two cylinders are inserted in the penis and connected by tubing to a separate reservoir of fluid. The reservoir is implanted under the groin muscles. A pump is also connected to the system and sits under the loose skin of the scrotal sac, between the testicles. The man presses on the pump to inflate the implant (no pressure is put on the testicles). Pumping transfers fluid from the reservoir to the cylinders in the penis, inflating them. Pressing on a deflation valve at the base of the pump returns the fluid to the reservoir, deflating the penis.
When the penis is inflated, the three-piece inflatable prosthesis gives the penis stiffness and thickness similar to a natural erection. Most men rate the erection as shorter than their normal erection, however. When the prosthesis is deflated, the soft penis is somewhat fuller than an normal penis. The newest model the Ultrex, has cylinders that may increase in length, as well as in thickness and stiffness, with inflation. The ability of the Ultrex to lengthen the penis with erection varies with the health and elasticity of the tissue in the penis. Even with the Ultrex, most men will have erections that are somewhat shorter than they were originally. Despite men’s concern about penis length, most women are not upset by this change. The sensitive part of a woman’s vagina is the outer third, closest to the entrance. Simulation deep inside the vagina is less important in helping a women reach orgasm than is having enough foreplay and good communication during sex.
Unless they could see the small surgical scar where the bottom of the penis meets the scrotal sac, other people would probably not be able to tell that a man had an inflatable penile prosthesis. Most men would not be embarrassed in a locker room or public rest room, for example. A penile prosthesis does not change sensation on the skin of the penis or a man’s ability to reach orgasm. Ejaculation and urination are not affected. Once a penile prosthesis is put in, however, it destroys the natural erection reflex. Men usually cannot get an erection without inflating the implant. If the implant is removed, the man will never again have natural erections.
About 90% to 95% of inflatable prosthesis surgeries are successful; that is, the implants produce usable erections. It is not known how many men have the surgery and then are rarely sexually active, however. Satisfaction rates with an inflatable implant are high; typically 80% to 90% of men express satisfaction and say that they would choose surgery again. More detailed questions, however, suggest that some men who overall say they made the right choice still feel dissatisfied with the appearance and size of the penis or their pleasure during sex.
More information on impotence (erectile dysfunction)What is impotence or erectile dysfunction? - Impotence is the inability of the male to have an erection. Some men may become impotent after having diabetes for a long time because the nerves or blood vessels have become damaged. Impotence may have a physiological or psychological basis.
How does erection occur? - Erection begins with sensory and mental stimulation. Impulses from the brain and local nerves cause the muscles of the corpora cavernosa to relax, allowing blood to flow in and fill the open spaces.
What causes impotence? - A common cause of impotence is a high level of atherosclerosis in the arteries feeding the penis. Damage to arteries, smooth muscles, and fibrous tissues, often as a result of disease, is the most common cause of impotence.
What are the physical causes of impotence? - Physical impotence occurs when there is a problem with any of the systems needed to get or maintain an erection. Hardening of the arteries can affect the artery leading to the penis so that it cannot dilate enough to deliver all the blood necessary for an erection.
What are the psychological causes of impotence? - Psychological causes of impotence often include work pressures, financial worries, fear of aging, or frustration with relationships. Depression and anxiety disorders are cited as the most common causes of psychological impotence.
How is impotence (erectile dysfunction) treated? - Treatment depends on the cause. Testosterone supplements may be used for cases with hormonal deficiency. Drugs for treating impotence can be taken orally or injected directly into the penis.
What're non-prescription treatments for impotence? - Among the herbs used for erectile dysfunction are yohimbine, gingko biloba (to increase blood flow), ginseng, pygeum, and muira puama. A penile sheath is a rigid or semi-rigid support put over the penis to support it for intercourse.
What is MUSE? - MUSE is short for "medicated urethral system for erection." This treatment is based on the discovery that the urethra can absorb certain medications, which can then pass into the surrounding erectile tissue creating an erection.
What is Viagra (sildenafil citrate)? - Viagra (sildenafil citrate), a prescription medication for the treatment of erectile dysfunction, is the first pill available that's been proven to improve erections in most men with impotence.
What is Levitra (vardenafil)? - Levitra (vardenafil HCl) is a PDE inhibitor drug. This medication helps improve erection during sexual arousal and activity but erection should end after sexual activity is complete.
What is Cialis (tadalafil)? - Tadalafil (Cialis?) is a drug used to treat male erectile dysfunction (impotence). The generic name for this compound is tadalafil.
What about penile injection therapy? - Penile injection therapy is non surgical technique used to treat impotence. Penile injections have the advantage of not involving surgery. They are also effective in many dialysis patients.
What are penile implants for impotence? - Penile implants (often called "internal penile pumps") are one of several erectile dysfunction treatment options. The inflatable penile prosthesis is a pump system surgically placed in the penis.
What is hormonal therapy for impotence? - Sexual desire (libido) and an overall sense of well-being are likely to improve when serum testosterone levels (the level of the male hormone in the blood) are restored.
