Everything you need to know about semi-rigid penile implants

When talking about prosthetic penile implants, there are various kinds of prostheses that men can opt for correcting their erectile dysfunction, including Semi-rigid penile implants. However, for the sake of simplicity, medical professionals and prosthetic surgeons segregate the different penile prosthesis types into two broad categories-inflatable implants and non-inflatable implants. Non-inflatable and inflatable implants are further subdivided into distinct kinds, mainly regarding structure and functionality.

Inflatable penile prostheses are more extensively used, compared to the non-inflatable because of the former’s inherent benefits. However, we’re going to focus on non-inflatable or semi-rigid penile implants in this blog, discussing the different types along with the advantages and drawbacks of each.

Non-inflatable penile implants

Non-inflatable penile implants are so called because these prosthetic devices come with rods or tubes that cannot be inflated and have a semi-rigid structure. Malleability and rigidness are the chief traits of non-inflatable implants, and owing to these distinctive, singular characteristics, the chances of leakage are minimal. At the same, these unique features enable the prostheses to remain in a functioning mode round the clock, and their fluid exchange requirement is less in comparison to inflatable models.

The non-inflatable, semi-rigid implants comprise chiefly of two pliant, bendable tubes constructed from a silicone material or coiled metallic wires. Once the prosthesis is successfully implanted inside your penis, you can expect an improved rigidity during coitus and also keep the organ concealed owing to the special materials used and also due to its shape and structure.

Another kind of non-inflatable, semi-rigid penile prosthesis that is somewhat less popular has silicone rods composed of articulating segments joined or interlocked with each other via a spring-activated cable on both ends. The spring-powered cables contribute towards keeping the polytetrafluoroethylene-coated ring segments in an erect and firm position as well as make them flaccid when deactivated.

The non-inflatable prostheses are supremely suitable for those whom durability and convenience of use matter more than the cosmetic benefits of inflatable penile prostheses or IPPs. Non-inflatable implants are embedded by making a ‘penoscrotal’ or an infrapubic incision which is larger in comparison to openings created for inserting inflatable tubes. Sometimes, the surgeon makes a partial subcoronal opening for placing the semi-rigid rods.

Semi-rigid implants pros

  • Firmer erections can be achieved easily
  • Particularly suitable for patients with  partial dexterity
  • The surgical process is less complicated, and hence less expensive compared to IPP surgeries
  • Lower risks of dysfunction or malfunctioning owing to the simplicity of the structure


  • The penis may remain firm and somewhat making it prominent even under layers of clothing
  • You could suffer from chronic pain if the implantation is not done effectively

Concluding remarks

We sincerely hope that you’ll have a better idea about non-inflatable (both semi-rigid and articulating segments types) penile prostheses. The semi-rigid prosthetic penile implant (SPP) continues to be a feasible treatment option for a good proportion of males with ED, the better effectiveness rates (read satisfaction) of inflatable implants notwithstanding. Semi-rigid implants are still popular primarily because of their affordability and durability without a significant tradeoff regarding coital satisfaction.
