Gelded means castrated. The term is mostly used for male horses that have had their testicles removed.
Meaning
Gelding means castrating a male animal, especially a horse.
Why
Geldings are calmer, easier to handle and can’t breed.
Process
A vet removes the testicles, usually under anesthesia. Recovery takes 1 to 2 weeks.
Gelding vs stallion
A stallion is an uncastrated male horse.
Other uses
Used for other animals, such as sheep or goats, but “neutered” is more common for pets.
Surgery details

Gelding is the castration of a male horse, usually done by removing the testicles under general anesthesia or sedation with local anesthetic. It is one of the most common surgeries performed on horses.
Age
Colts are often gelded between 6 months and 2 years of age, though a gelding can be done at any age. Early castration may be done before a horse develops stallion behavior.
Why geld
- Calmer, more manageable behavior.
- Reduced aggression toward horses and people.
- Easier to keep with mares and other horses.
- Prevents unwanted breeding.
Most horses are geldings, as only a small number of male horses are kept as breeding stallions.

Recovery
Horses are usually kept in a clean stall or small paddock, then given gentle exercise to reduce swelling. Healing takes 2 to 3 weeks. Risks include swelling, bleeding, infection and, rarely, herniation. A veterinarian provides tetanus protection and pain control.
Behavior afterward
Testosterone levels fall, but some stallion behavior may remain, especially if gelded late. Geldings can still show mounting or aggression in rare cases.
Other animals
Male cats, dogs and livestock are castrated or neutered. In cattle, a castrated male is a steer. In pigs it’s a barrow, and in sheep a wether.
Figurative use
In the figurative sense, “gelded” means weakened or deprived of power or strength, as in a gelded law.
Cost
Veterinary costs range from about 200 to 600 dollars, depending on the age, the clinic and complexity.
Surgical details in horses
To geld an animal means to castrate a male, most often a horse. Colts are usually gelded at about 6 months to 2 years old, and the procedure removes both testicles under sedation and local anesthesia while standing or general anesthesia while lying down. Costs vary by region and method, often a few hundred up to about 1,000 USD. Recovery takes about 2 to 3 weeks, with controlled exercise and daily monitoring for swelling, bleeding or infection. Complications are uncommon, but include swelling, infection and rarely herniation.
Behavior and other animals
Gelding reduces testosterone driven behavior such as aggression and mounting, but training and personality also matter, and some horses keep stallion like behavior. Other male animals such as cattle (steers), sheep, pigs and cats are castrated too, but “gelded” is mostly used for horses. The word is also used figuratively to mean weakened or deprived of strength, for example “a gelded law.” Gelded horses can compete and are the majority of male racehorses in many disciplines.
