Summary

Equine castration is also known as gelding or emasculation, a surgical procedure that involves removal of the testicles and part of the spermatic cord. Castration is commonly performed to prevent unwanted breeding and reduce stallion‑like behaviors such as aggression, biting, mounting, and fighting, making horses easier to manage and board. The ideal age for castration is typically between 6 and 12 months, provided both testicles are present; cases of cryptorchidism require more advanced surgery. The document outlines what to expect during the procedure, which may be done standing with sedation or under general anesthesia, and describes potential complications such as bleeding, swelling, infection, and the rare but serious risk of evisceration. Recommended aftercare includes short‑term stall rest, daily controlled exercise, anti‑inflammatory medication, and cold hosing to reduce swelling.
