Inflatable vs Semi-Rigid Penile Implants: Which is Right for You?
By Dr. Zülfü Sertkaya's Team · 7 min read · Updated May 2025
The two main types of penile implant — inflatable and semi-rigid — each have distinct advantages. The right choice depends on your anatomy, lifestyle, and manual dexterity. Dr. Sertkaya will guide you to the optimal decision during your consultation.
The Two Main Types of Penile Implant
When considering penile prosthesis surgery in Turkey, one of the most important decisions is choosing between an inflatable (hydraulic) implant and a semi-rigid (malleable) implant. Both are highly effective, but they differ in mechanism, appearance, and the level of manual interaction required.
Three-Piece Inflatable Penile Implant
The inflatable penile prosthesis (IPP) is the most widely chosen and most technologically advanced option. It consists of three components: two cylinders placed within the corpora cavernosa of the penis, a fluid reservoir typically implanted behind the pubic bone, and a small hand-operated pump placed in the scrotum.
How it works: The patient squeezes the scrotal pump several times, transferring saline fluid from the reservoir into the cylinders, creating a firm erection. To deflate, a release valve on the pump is pressed, returning fluid to the reservoir.
| Feature | 3-Piece Inflatable | Semi-Rigid |
|---|---|---|
| Mechanism | Fluid pump (scrotal) | Manual bending |
| Flaccid appearance | Completely natural | Constant semi-erect |
| Erect rigidity | Excellent | Good |
| Girth increase | Yes (with expansion) | No |
| Ease of use | Requires dexterity | Very simple |
| Mechanical reliability | Very high (>95% at 10yr) | Extremely high |
| Patient satisfaction | ~95% | ~90% |
| Best for | Active lifestyle, natural appearance | Dexterity issues, simplicity preference |
Which Should You Choose?
For most patients, the three-piece inflatable prosthesis is the preferred choice due to its natural flaccid appearance, superior rigidity when inflated, and highest patient satisfaction data. The Coloplast Titan Touch and Boston Scientific AMS 700CX are both excellent options in this category.
The semi-rigid implant may be more appropriate if you have reduced hand dexterity (e.g., due to arthritis or neurological conditions), prefer a simpler device with fewer mechanical components, or have a penile anatomy that makes cylinder placement for an inflatable device more complex.
Ultimately, the decision should be made collaboratively with your surgeon following a thorough assessment of your anatomy and lifestyle. Dr. Sertkaya provides a detailed, individualised recommendation during your consultation.
