The spermatic cord is made up veins, artery, nerves, and the vas deferens, the tube which carries sperm away from the testicles. The spermatic cords are crushed with an emasculator for about sixty seconds to sever them. The veterinarian enlarges the scrotal incisions and trims any excess scrotal tissues that would interfere with proper drainage. It is important he is in a safe, private place such as a round pen or arena. Before turning him out, apply petroleum jelly to the insides of his hind legs where sticky fluids will later drip.
Accumulated drainage can result in sloughed hair and chafed skin.
Petroleum jelly will protect the sparsely-haired inside thigh and gaskin area from scalding and makes daily cleaning of the legs easier for the owner and less painful for the horse. Drainage is largely comprised of white blood cells mixed with discarded tissue fragments and blood. Commonly this is referred to as pus. As long as the odor of the drainage remains inoffensive, it is normal and desirable. Drainage should continue for 2 to 3 weeks.
