A gelding is a castrated male horse, donkey or mule. Unless a horse is to be used for breeding purposes, it should be castrated. Gelding can make horses more even tempered and easier to handle. A stallion who is gelded later in life may retain more aggressive stallion-like behavior. A colt may be gelded before it is one year old -- as soon as the testicles descend into the scrotum.
