3-piece inflatable penile implant
A 3-piece inflatable penile implant is a surgically implanted hydraulic prosthesis used to provide reliable erections for men with erectile dysfunction that does not respond adequately to medications or other conservative treatments. The system consists of two inflatable cylinders placed inside the corpora cavernosa, a pump positioned in the scrotum, and a separate fluid reservoir usually placed in the pelvis or lower abdomen. Activating the pump transfers fluid from the reservoir into the cylinders to create penile rigidity, while deflation returns the fluid to the reservoir and allows the penis to become softer and easier to conceal.
- +Fully concealed — nothing is visible from outside the body
- +Penis stays completely soft when deflated
- +Gives good girth and rigidity when inflated, closer to a natural erection than simpler implants
- +Erection available on demand, with no tablets, injections or waiting time
- +Device survival of 87.2% at five years across 20,161 patients
- +Patient and partner satisfaction reported at around 80–90%
- +Lock-out valve designs reduce unwanted spontaneous inflation
- +Narrow-base versions available for scarred or fibrotic tissue and repeat implantation
- +Suitable for men with Peyronie's disease who also have erectile dysfunction
- −Permanent and irreversible — erectile tissue is destroyed, and tablets or injections will not work if the device is removed
- −Adds no length; pre-operative stretched flaccid length is the maximum achievable
- −Infection risk around 1 in 100, rising to about 1 in 10 in diabetes or replacement surgery
- −An infected device must be removed entirely
- −Device survival falls to 76.8% at ten years and 52.9% at twenty years — revision is likely over a lifetime
- −Fluid leakage from tubing fractures or cylinder tears is the most common cause of failure
- −Glans droop reported at 1 in 10 to 1 in 50
- −Erosion of the device reported at 1 in 20 to 1 in 50
- −Altered glans sensation, which can be permanent
- −Injury to urethra, bowel or bladder at 1 in 50 to 1 in 250
- −Abdominal reservoir adds rare risks of herniation or erosion into nearby organs
The AMS 700™ CX is a 3-piece inflatable penile prosthesis designed to provide strong axial rigidity and controlled girth expansion for men with erectile dysfunction who are candidates for penile implant surgery.

The AMS 700™ LGX is a 3-piece inflatable penile prosthesis designed to provide controllable rigidity with controlled expansion in both penile length and girth during inflation. It is intended for men with erectile dysfunction who are candidates for penile implant surgery and differs from the AMS 700 CX primarily through its longitudinal expansion capability.
- 3-piece hydraulic system — Two inflatable intracavernosal cylinders, scrotal pump and separate reservoir.
- Length + girth expansion — LGX is specifically engineered for controlled longitudinal and circumferential expansion.
- Established AMS 700 platform — Long-standing clinical use with substantial published evidence.

- Separate fluid reservoir — Supports strong inflation and good deflated concealability.
The Coloplast Titan® is a 3-piece inflatable penile prosthesis designed to provide controllable penile rigidity for men with erectile dysfunction who are candidates for penile implant surgery. It uses Bioflex® cylinders, a scrotal pump and a separate fluid reservoir, with a hydrophilic surface treatment that allows the implant to absorb an aqueous solution selected by the surgeon.
- 3-piece hydraulic design — Paired intracavernosal cylinders, scrotal pump and separate fluid reservoir.
- Bioflex® cylinders — Proprietary cylinder material engineered for rigidity and durability.
- HydroVANTAGE™ hydrophilic coating — Absorbs an aqueous solution selected by the surgeon during device preparation.
