The male guinea pig is known as the Boar. The genital organs consist of the testes, accessory sex glands and the perianal & caudal glands. The perineal sacs are present in both sexes, but are more extensive in the male. They lie on either side of the anus and contain extensive caseous secretions, hair and skin debris. | The male guinea pig is known as the Boar.
