There are many more terms used to describe male horses than females because they not only indicate the gender and age of the horse but can also reveal whether they are fathers, if they've been castrated or not and if they have developed and matured properly. Colts are those male horses who are less than 4 years old. When they turn 4, male horses become stallions -- unless they are castrated. Male horses who are altered are referred to as geldings. If a horse has fathered a baby, he's called a sire. Another term used to describe male horses is rig, which refers to a male horse who either hasn't been castrated properly or has one or two undescended testicles.
