Penile implants are medical devices surgically placed inside the penis to help men with erectile dysfunction (ED) achieve and maintain an erection. Typically recommended when other treatments have failed, these implants come in inflatable or flexible rod types. Inflatable implants involve a saline-filled device and a pump hidden in the scrotum. When pressed, the pump sends fluid into the implant, causing an erection; the device can later be deflated.
There are three main types of penile implants: a 3-piece inflatable implant, a malleable implant, and a rigid implant. The 3-piece inflatable version offers the most natural-feeling erection. Malleable rods provide a semi-rigid penis that can be positioned manually. All types are custom-fitted, allowing for satisfying intercourse. Sensation and the ability to ejaculate are generally unaffected.
The primary difference lies in how natural the erection feels. Inflatable implants mimic natural erections more closely, while malleable rods provide a constant firmness.
No, penile implants do not affect urination. The implant is placed in the erectile chambers and does not interfere with the urinary passage.
Modern penile implants are highly durable and often last more than 20 years. However, like any mechanical device, failure is possible. If the implant fails, revision surgery is required, which is similar to the original implantation procedure.
Yes, in some cases, implants can act as a tissue expander and may increase penile length and girth, particularly in men with severe or long-term erectile dysfunction.
