Why Many Veterinarians Recommend Castration Over Vasectomy?

Castration involves the removal of a dog’s or cat’s testes. In addition to losing their capacity to impregnate, the absence of testosterone hormone keeps male cats from spray marking, straying far, and displaying aggressive tendencies.

Vets very rarely perform vasectomies, doing them only under specific circumstances. It involves the removal of a section of the spermatic cord, which prevents sperm from traveling. Unlike castration, the testes still continue to produce testosterone so the inherent male behavior and characteristics are still very much intact. This means males continue to seek out females during the mating season, aggressive tendencies are still very much strong, and they also engage in spray marking. Testosterone also stimulates the prostate to continue to grow, increasing a dog’s risk to testicular issues which are very common in older intact dogs. These problems can vary from benign prostatic hyperplasia to malignant conditions.

With these being said, castration is highly recommended over vasectomy in dogs and cats for the procedure’s medical and societal benefits. For additional details, visit this homepage.
