== Neuter vs. Spay ==
Neutering and spaying are surgical procedures to prevent pets from reproducing.<ref name="ref1" /> While both terms refer to sterilization, "neuter" is often used for male animals and "spay" for females.<ref name="ref2" /><ref name="ref3" /> The general term for sterilizing an animal of either sex is neutering.<ref name="ref4" /> Other terms used include desexing, altering, or fixing.<ref name="ref5" />

The primary distinction between the procedures is the sex of the animal and the reproductive organs that are removed. Spaying a female animal, technically an ovariohysterectomy, involves the removal of the ovaries and uterus. Neutering a male animal, or castration, is the removal of the testicles. Both surgeries are performed under general anesthesia.<ref name="ref5" />

=== Health and Behavioral Considerations ===
Sterilization can lead to a longer and healthier life for pets. Spaying females can prevent uterine infections and breast cancer. For males, neutering eliminates the risk of testicular cancer and reduces the likelihood of some prostate problems.

Neutering can also affect an animal's behavior. In males, it can decrease aggression, roaming to find mates, and urine marking.<ref name="ref4" /> Spayed females will no longer go into heat, which can prevent behaviors associated with the mating cycle. One of the main reasons for these procedures is to control the pet population and reduce the number of homeless animals.<ref name="ref2" />
