Differences between Neuter and Spay
Contents
Neuter vs. Spay[edit]
Neutering and spaying are surgical procedures to prevent pets from reproducing.[1] While both terms refer to sterilization, "neuter" is often used for male animals and "spay" for females.[2][3] The general term for sterilizing an animal of either sex is neutering.[4] Other terms used include desexing, altering, or fixing.[5]
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.[5]
Comparison Table[edit]
| Category | Neuter | Spay |
|---|---|---|
| Gender | Male | Female |
| Procedure | Orchiectomy (Castration) | Ovariohysterectomy |
| Organs Removed | Testicles | Ovaries and Uterus |
| Surgical Approach | An incision is made near the scrotum. | An incision is made in the abdomen. |
Health and Behavioral Considerations[edit]
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.[4] 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.[2]
