A penile prosthesis is a medical device inserted into the penis to help men with erectile dysfunction (ED) get and keep an erection. This option is usually considered when other treatments, such as medications or vacuum devices, are ineffective. There are two main types of penile prosthesis: inflatable and flexible. Inflatable prostheses consist of a pump and fluid-filled cylinders that can be inflated for an erection and deflated when not in use. Flexible prostheses, on the other hand, are semi-rigid rods that can be bent into position for sexual intercourse. The prosthesis insertion procedure is usually performed under general anesthesia and involves inserting the device into the penis. Although the surgery carries risks such as infection or mechanical failure, many men report high satisfaction rates after implantation, as it can significantly improve their quality of life and intimacy with their partner. It is important for men considering this option to consult with a qualified urologist to discuss the possible benefits, risks and what to expect during recovery.
