Emasculator Applied.

Emasculator Applied.
The jaws of the emasculator are placed on the spermatic cord with the "nut towards the nut" (the wing nut of the instrument towards the testicle). This orientation ensures that the proximal end of the cord is crushed and the distal end is severed, to prevent bleeding. Because of the large size of caprine testes, an equine emasculator is needed.
