A compact, some what flattened and whitish mass, called epididymis is closely abutted against the dorsal aspect of each testis. In rabbit head of epididymis present at the head of the testis is called caput epididymis. Epididymis differentiated into smaller posterior enlarged part called cauda epididymis. Testes of rabbits are about 15 to 20 mm long and 10 mm thick, oval and pinkish structures. Each is held in its position within its scrotal sac and is supported from posterior scrotal wall by means of a small cord of fibro-muscular mesodermal tissue called gubernaculum. From the tip of cauda epididymis, the Wolffian duct continues forwards as an uncoiled and some what thicker male genital duct orvas deferens.
