The Burdizzo is a castration device that employs a large clamp designed to break the blood vessels leading into the testicles. Once the blood supply to the testicles is lost, testicular necrosis occurs, and the testicles shrink, soften, and eventually deteriorate completely. When the device is used the operator crushes the spermatic cords one at a time, leaving a space in between to maintain an interruption of blood flow to the scrotum.
