Penile prosthesis is an artificial device which is implanted in men for the treatment of erectile dysfunction. Erectile dysfunction is a condition where a man is unable to maintain sufficient erection for sexual intercourse.
Penile implants have two main types: semi-rigid (malleable or non-hydraulic) and inflatable (hydraulic) implants.
When the pump is pressed, the fluid from the reservoir is transferred to the cylinders, inflating it so that the penis becomes stiff. The cylinders can be inflated at the time of erection and deflated after the intercourse.
Potential complications of inserting penile implants include but are not exclusive to bleeding, infection, scar tissue formation, and erosion of tissue around the implant and mechanical failure.
