What Is a Penile Implant?
A penile implant is not a makeshift solution. It is a precisely engineered medical system that allows men with severe erectile dysfunction to achieve a permanently controlled, natural-feeling erection.

What Is a Penile Implant?
A penile implant – also known as a penile prosthesis – is a surgically implanted system that mechanically replaces the body's own erectile function. It is used once all other treatment options have been exhausted or are not suitable.
Unlike medication or injections, which rely on existing biological mechanisms, the implant functions entirely independently of nerve signals, hormones, or the penis's blood supply. This makes it the most effective option for severe erectile dysfunction – regardless of the underlying cause.
All components of the system are fully concealed inside the body. Nothing is visible from the outside – neither in the flaccid nor in the activated state.
The Three Components of the Hydraulic Penile Prosthesis
The gold standard is the three-piece hydraulic penile prosthesis – internationally known as the three-piece inflatable penile prosthesis. It consists of three main components, all inserted through a single small incision between the penis and scrotum:
1. The Cylinders
Two soft, pliable cylinders are inserted into the natural erectile tissue of the penis – the very structures responsible for erection in a healthy man. When not activated, they lie relaxed and allow a normal flaccid appearance. When inflated, they fill with fluid and produce a firm, even erection.
2. The Pump
A small pump is placed in the scrotum. By pressing it gently several times, fluid is transferred from the reservoir into the cylinders – producing the erection. A small valve on the pump allows the fluid to be released again, ending the erection. Operation is simple and discreet – no one else notices what is happening.
3. The Reservoir
A small reservoir is placed through the same skin incision in the lower abdomen, behind the pubic bone. It stores the sterile fluid needed for the erection and reabsorbs it once the erection ends. It is neither visible nor palpable from the outside.
How an Erection Is Triggered – Step by Step
- Gently press the pump in the scrotum a few times
- Fluid flows from the reservoir into the cylinders
- The cylinders fill – the penis becomes erect and firm
- To end the erection: press the release valve on the pump
- Fluid flows back into the reservoir – the penis becomes flaccid again
The entire process takes only a few seconds. With a little practice – the first activation takes place around four weeks after the procedure – it becomes routine.
Modern Penile Implants – What They Can Do
- Various sizes and diameters for an optimal, individually suited fit
- Antibacterial coating on the cylinder surface to reduce infection risk
- Especially soft, natural-feeling cylinders for an authentic sensation
- All components fully concealed inside the body – no visible parts
- High mechanical durability – modern implants are designed to last for decades
With high-quality implantation and optimal size selection, the result feels so natural that studies document partner satisfaction of up to 88 percent.
Why a Three-Piece Implant Is the Gold Standard
| Characteristic | Two-Piece / Semi-Rigid | Three-Piece (UGRS Standard) |
|---|---|---|
| Erection | Limited | Full, natural |
| Detumescence | Incomplete / always semi-rigid | Complete |
| Discretion | Low to moderate | High |
| Patient satisfaction | Moderate | Very high |
| Surgical complexity | Low | Higher – requires more experience |
The decisive difference: two-piece or semi-rigid systems can never let the penis become fully flaccid. It always remains semi-rigid – which many men find uncomfortable in everyday life and conspicuously awkward in intimate situations. The three-piece solution allows a fully normal transition between erection and detumescence.
Frequently Asked Questions About Function
No – with professional implantation, all three components are fully concealed inside the body. The pump in the scrotum can only be felt through deliberate touch – comparable to the natural tissue of the testicle. Many patients report that partners do not notice a difference.
Modern three-piece implants are designed for a service life of 15 to 20 years or more. Mechanical defects are rare – if they occur, the implant can be replaced through a revision procedure.
Yes. The implant changes neither the sensitivity of the penis nor the ability to reach orgasm. It replaces only the mechanical erectile function – all other sexual functions remain intact.
No. A professionally implanted penile prosthesis does not interfere with later treatment of the prostate or other urological conditions.
