Reproductive tract disorders are the third most common reason for guinea pigs to be presented for veterinary attention, following dental disease and skin disease. A wide range of reproductive disorders affect guinea pigs and knowledge of the anatomy and common problems affecting the reproductive tract are essential in diagnosing and treating reproductive disease.
