 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 in order to maintain uninterrupted blood-flow to the scrotum
Scrotum
In some male mammals the scrotum is a dual-chambered protuberance of skin and muscle containing the testicles and divided by a septum. It is an extension of the perineum, and is located between the penis and anus. In humans and some other mammals, the base of the scrotum becomes covered with curly...

, compared with traditional methods. However, because the burdizzo was not originally designed for human use, and because fairly little research has been done on burdizzo castrations in humans, many physicians and others do not consider the burdizzo to be a safe castration method for humans. While the risks of blood loss and infection are low, anesthesia is a must, as the burdizzo causes blunt force causing trauma to the spermatic cords, which are thickly wrapped in nerve fibers.
