Resulting alterations at the level of testes and semen in dogs submitted to vincristine sulphate administra tion
Keywords:Dogs, Vincristine sulphate, Semen, Antineoplastic agents
Sperm analysis and testicular histological studies were performed before and after vincristine sulphate treatment, in fourteen male dogs. In group I (n = 8), unilateral orchiectomy was carried out before and after mitostatic treatment, and testicular and epididymal biopsies were examined histologically. All histological examinations showed a slight to moderate degeneration of testicular tissue. In group II (n = 6) semen was collected and was submitted to laboratorial analysis. After vincristine treatment, middle piece and tail abnormalities were found. However, as physical and morphological abnormalities showed to be reversible, vincristine sulphate therapy may be used in such species.
