Penis

6.3K
The penis serves a dual role in sexual reproduction and urination. It consists of three main regions: the glans penis, the body, and the root, each with distinct functions and unique anatomical features.
Anatomy of the Penis
The glans penis, or the head, is the terminal part of the penis and houses the external urethral orifice, the exit point for urine and semen. Covered by the prepuce, or foreskin, the glans is noted for its sensitivity and plays a key role in sexual pleasure. The body of the...

Area of Science:

  • Urology
  • Medical Device Technology
  • History of Medicine

Background:

  • Erectile dysfunction (ED) treatment has a long history, with penile prostheses evolving over centuries.
  • The development of penile implants for sexual function began in the twentieth century.
  • Innovation in penile prosthetics has been driven by trial and error since their introduction in 1936.

Approach:

  • This review provides an overview of penile prostheses used for ED treatment since 1936.
  • It highlights key technological advancements and design modifications in penile implant development.
  • The review also examines abandoned concepts and looks toward future innovations.

Key Points:

  • Significant advances include two-piece inflatable, three-piece inflatable, and malleable/semirigid penile prostheses.
  • Modifications have enhanced the usability and insertion of existing penile implant designs.
  • Past "dead ends" in development offer lessons learned from historical attempts.

Conclusions:

  • Penile prostheses have undergone substantial evolution, improving ED management.
  • Future developments are expected in remotely activated devices and prostheses for specific populations, such as transgender men.
  • Continued innovation aims to further enhance patient outcomes and quality of life.
