PERSPECTIVES ON THE USE OF CHEMICAL CASTRATION AS AN ALTERNATIVE TO ORCHIECTOMYA IN DOGS

Abstract

Chemical castration has been increasingly discussed in Veterinary Medicine as an alternative to orchiectomy, especially in the context of canine population control. This method uses sclerosing drugs applied intratesticularly or into the epididymis, promoting a gradual reduction in spermatogenesis, with advantages such as lower cost, technical simplicity, and faster recovery. This study aimed to describe the functioning of the male canine reproductive system, addressing anatomical, physiological, and endocrine aspects, as well as clarifying the technique and physiological mechanism of chemical castration, highlighting its advantages over the surgical method. Specifically, it sought to contextualize the reproductive anatomy of the domestic dog, identify factors influencing the choice of chemical castration, and describe the technique employed in this procedure. The methodology adopted consisted of a descriptive and qualitative literature review, using databases such as Google Scholar, Crossref, DOAJ, and specialized books, covering publications between the years 2000 and 2024. It is concluded that, although chemical castration presents operational and hormonal benefits, its application should be carefully evaluated, considering physiological aspects, animal welfare, and current legal limitations.
