💬 In Plain English

A neuter (clinically called an orchiectomy or castration) is the surgical sterilization of a male dog or cat. Under general anesthesia, a small incision is made (just in front of the scrotum in dogs, or directly over the scrotum in cats), and both testicles and their associated sperm cords are securely tied off and removed. Neutering completely prevents testicular cancer, significantly lowers the risk of prostate disease in older dogs, and reduces roaming, urine marking, and male-on-male territorial aggression.
