Normal erection is the result of many factors working together.

Other forms of therapy including self injection programs with vasoactive drugs, intraurethral placement of vasoactive drugs, external vacuum compression device, and implantation of inflatable penile prostheses are still available and have a place in the armamentarium of the urologist who deals in the problems of sexual dysfunction in men.
