The male cat’s reproductive tract includes two testicles, housed within the scrotum, and the bulbourethral and prostate glands, which lie within the pelvic canal. Cats that will not be used for breeding should be castrated (surgical removal of the hormone producing testicles) to prevent pet overpopulation and unwanted behaviors (e.g.: inter-cat aggression and roaming to find a mate). Sterilizing your cat will not change their loving personality; it will make them less prone to illness. A castrated cat will focus more on your family rather than finding a mate.
