Detailed Answer
A penile implant, also known as a penile prosthesis, is a surgical treatment option for men with erectile dysfunction (ED) who have not had success with or cannot use other treatments such as oral medications, vacuum devices, or intracavernosal injections. It is designed to allow an erection sufficient for sexual activity and restore sexual function.
There are two main types of penile implants: inflatable and malleable (semi-rigid). Inflatable implants consist of cylinders placed in the penis, a fluid reservoir, and a pump located in the scrotum. When the man squeezes the pump, fluid moves into the cylinders to create an erection. These implants provide a more natural appearance and allow the penis to remain flaccid when not in use. Malleable implants consist of bendable rods that can be manually adjusted for intercourse. They are easier to use but result in a penis that is always somewhat firm.
Penile implant surgery is typically performed under general or spinal anesthesia. Most patients can return home the same day or after a short hospital stay. Recovery involves avoiding strenuous activities and sexual intercourse for several weeks, depending on individual healing and the type of implant used; your surgeon will advise when it is safe to resume them.
Penile implants have high satisfaction rates: with appropriate counseling, 92-100% of patients and 91-95% of partners are satisfied, according to the EAU Guidelines. They do not usually affect ejaculation or the ability to orgasm, although some men notice changes in sensation that can improve with time. Additionally, implants are not visible from the outside, and modern designs are highly reliable.
The most common risks include infection (about 2-3% for first-time implants in low-risk patients at high-volume centers, and 1-2% with antibiotic-impregnated or hydrophilic-coated implants) and mechanical failure over time. Advanced surgical techniques and antibiotic-coated implants have significantly reduced infection complications. The devices typically last 10-15 years, with some functioning well beyond that time frame.
Men considering a penile implant should consult a urologist experienced in prosthetic surgery to discuss expectations, device options, and the surgical process. Psychological counseling may also enhance outcomes by addressing concerns about sexual performance and relationship dynamics.
From the Guidelines
"The surgical implantation of a penile prosthesis may be considered in patients who i) are not suitable for different pharmacotherapies or prefer a definitive therapy; and, ii) do not respond to other treatment modalities." (p. 55) "Regardless of the indication, prosthesis implantation has one of the highest satisfaction rates (92-100% in patients and 91-95% in partners) among the treatment options for ED with appropriate counselling." (p. 56)
