Erection
Surgical implants – If other treatments do not work, a last method may be for the impotent man to go for surgery and have a penile implant put into his penis. Modern implants are made up of cylinders that are put inside the corpora cavernosa penis. The cylinders are connected by tubes to a pump that is put under the skin near the testicles. When the pump is used, it pushes fluid into the cylinders, which become hard and cause an erection. After the man has finished having sex, he can press a valve that allows the fluid to flow out from the cylinders.
