Orchiectomy in Guinea Pig- A Case Report

Guinea pigs (Cavia porcellus) are mainly maintained for immunological and biological research. Generally, the males are kept in groups and often inflict injury on account of their aggressive behavior. Male guinea pigs attain sexual maturity by 4-6 weeks of age and are capable of impregnating the sows (Richardson, 2000). Therefore, it is suggested that in order to prevent over population and prevent injury the male guinea pigs must be castrated after 3-4 months of age. Orchiectomy has been performed by open closed technique using prescrotal and scrotal incision under general anesthesia (Anderson and Froimovitch, 1974).
