A penile implant is an implanted device intended for the treatment of erectile dysfunction, Peyronie's disease, ischemic priapism, deformity and any traumatic injury of the penis, and for phalloplasty or metoidioplasty, including in gender-affirming surgery. Men also opt for penile implants for aesthetic purposes. Men’s satisfaction and sexual function is influenced by discomfort over genital size which leads to seek surgical and non-surgical solutions for penis alteration.[1] Although there are many distinct types of implants, most fall into one of two categories: malleable and inflatable transplants.[2]The first modern prosthetic reconstruction of a penis is attributed to NA Borgus, a German physician who performed the first surgical attempts in 1936 on soldiers with traumatic amputations of the penis. He used rib cartilages as prosthetic material and reconstructed the genitals for both micturition and intercourse purposes.[3] Willard E. Goodwin and William Wallace Scott were the first to describe the placement of synthetic penile implants using acrylic prosthesis in 1952.[4] Silicone-based penile implants were developed by Harvey Lash and the first case series were published in 1964.[5] The development of a high-grade silicone that is currently used in penile implants is credited to NASA.[6] The prototypes of the contemporary inflatable and malleable penile implants were presented in 1973 during the annual meeting of the American Urological Association by two groups of physicians from Baylor University (Gerald Timm, William E. Bradley and F. Brantley Scott) and University of Miami (Michael P. Small and Hernan M. Carrion).[3][7][8] Small and Carrion pioneered the popularization of semi-rigid penile implants with the introduction of Small-Carrion prosthesis (Mentor, USA) in 1975. Brantley Scott described the initial device as composed of two inflatable cylindrical bodies made up of silicone, a reservoir containing radiopaque fluid and two pumping units.[7] The first generation products were marketed through American Medical Systems (AMS; currently Boston Scientific), with which Brantley Scott was associated.[6][9] Many device updates have been released by AMS since the first generation implants. In 1983, Mentor (currently Coloplast) joined the market.[6] In 2017, there were more than ten manufacturers of penile implants in the world, however only a few now remain in the market.[10] The latest additions to the market are Zephyr Surgical Implants and Rigicon Innovative Urological Solutions.[11][12] Zephyr Surgical Implants, along with penile implants for biological men, introduced the first line of inflatable and malleable penile implants designed for sex reassignment for trans men.

According to analysis of the 5% Medicare Public Use Files from 2001 to 2010 approximately 3% of patients diagnosed with erectile dysfunction opt for penile implantation.[13] Each year nearly 25,000 inflatable penile prostheses are implanted in the USA.[14]

The malleable (also known as non-inflatable or semi-rigid) penile prosthesis is a set of a pair of rods implanted into the corpora of the penis. The rods are hard, but 'malleable' in the sense that they can be adjusted manually into the erect position.[16] There are two types of malleable implants: one that is made of silicone and does not have a rod inside, also called soft implants, and another with a silver or steel spiral wire core inside coated with silicone. Some of the models have trimmable tails intended for length adjustment.[10] Currently, a variety of malleable penile implants are available worldwide.[17]
