January 26, 2021, marked the 25th anniversary of implantation of the first Indian penile prosthesis. The prototype that was implanted was a pair of simple silicon rods; the patient was a 28-year-old school teacher who had failed to consummate his marriage due to severe erectile dysfunction, and had not benefited from intrapenile injections and venous ligation surgery (this was in 1996– the pre Viagra® era). After the implant surgery, he was able to have successful intercourse, fathered two daughters and was going strong 10 years later. Since then, the Shah Indian penile prosthesis has evolved through many models to reach its present form which is currently the most commonly implanted penile prosthesis in India (1098 implants were sold between January 2016 and January 2021, as per company sales figures). Presented here is the evolution of the Shah Indian implant so that an understanding of the various modifications may help optimize the utilization of this implant.
