How does a penile prosthesis work?

A penile prosthesis is a surgically implanted device that helps men with erectile dysfunction (ED) achieve and maintain an erection. There are two main types of penile prostheses: inflatable and semi-rigid.

• Inflatable penile prostheses are the most common type. They consist of two cylinders that are surgically implanted into the penis. The cylinders are connected to a pump that is placed in the scrotum. When the pump is squeezed, the cylinders fill with fluid, causing the penis to become erect. To deflate the penis, the man simply releases the pressure from the pump.
• Semi-rigid penile prostheses are made of silicone or other flexible material. They are implanted in the penis and remain semi-erect at all times. This type of prosthesis is not as popular as inflatable prostheses, but it may be a good option for men who do not want to deal with the hassle of inflating and deflating a pump.

Both types of penile prostheses are effective in treating ED. The type of prosthesis that is best for a man will depend on his individual needs and preferences.

The surgery to implant a penile prosthesis is typically performed under general anesthesia. The incisions are made in the scrotum and along the shaft of the penis. The procedure takes about 1-2 hours.

Most men are able to return home the same day as surgery. They may experience some pain and swelling, but this usually goes away within a few days.

Men with penile prostheses can usually resume sexual activity within 4-6 weeks after surgery.

Penile prostheses are a safe and effective treatment for ED. They can help men regain their sexual function and self-confidence.

A penile prosthesis is a medical device surgically implanted into the penis to help men with erectile dysfunction (ED) achieve and maintain an erection for sexual intercourse. There are two primary types of penile prostheses: inflatable penile prostheses and semi-rigid (malleable) penile prostheses. Each works differently:

1. Inflatable Penile Prosthesis (IPP):
   • Components: An inflatable penile prosthesis consists of three main components:
     • Two inflatable cylinders that are surgically implanted within the penis.
     • A fluid reservoir typically placed in the abdomen, although it can also be located in the scrotum in some cases.
     • A pump, which is usually implanted in the scrotum.
   • Operation: When a man wants to achieve an erection, he manually activates the pump located in the scrotum. This pump is connected to the fluid reservoir and the inflatable cylinders within the penis.
   • Erection Process: When the pump is activated, it transfers fluid from the reservoir into the cylinders, causing them to inflate. This inflation results in the penis becoming rigid and erect, allowing for sexual intercourse.
   • Deflation: After sexual activity, the patient can use the pump again to release the fluid from the cylinders back into the reservoir, deflating the penis and returning it to a flaccid state.
2. Semi-Rigid (Malleable) Penile Prosthesis:
   • Design: A semi-rigid penile prosthesis consists of two flexible rods that are surgically implanted within the penis. These rods maintain a semi-rigid state, allowing the penis to be positioned for intercourse.
   • Operation: Unlike the inflatable prosthesis, there is no need for a pump or fluid reservoir with a semi-rigid prosthesis.
   • Erection Process: To achieve an erection, the patient simply manually bends the penis into a more erect position, and the semi-rigid rods maintain this position.
   • Deflation: After intercourse, the patient can manually reposition the penis to a flaccid state.

Both types of penile prostheses allow men with ED to have an erection on demand, which can improve their ability to engage in sexual intercourse. The choice between an inflatable or semi-rigid prosthesis depends on a patient’s preferences and medical considerations, as well as the advice of their healthcare provider.

Penile prosthesis implantation is generally considered a safe and effective treatment for severe ED when other conservative options have failed. However, it is a surgical procedure with potential risks and complications, so individuals considering this treatment should consult with a urologist or specialist experienced in the procedure to make an informed decision.
