Abstract:

The present study was aimed to perform the alternative technique of chemical castration for controlling the increasing population of stray dogs. Eight adult male dogs were used in the current study. The dogs were Experimentally divided randomly into two groups. The first group included four dogs that were injected intratesticular with tannic acid while the second group which includes four dogs were injected intratesticular with normal saline and considered as a control group. The clinical examination, hormonal assay, and histopathological changes were detected. The result of the current study shown testicular tissue swelling in both treated and control groups this swelling subsided gradually within 48 hours, but without any serious complications. There were no significant changes in testosterone levels in both the control and treated groups. The histopathological results of the treated group after 30 days post-surgery showed focal necrosis and desquamation of germinal cells and Sertoli cells. We can conclude that chemical neutralization is a simple technique, can be used for controlling the increasing population of stray dogs.
