The most important feature is the absence of seminal vesicles in the Camelidae family. The accessory sex glands are: the ampullae, the prostate, the bulbo-urethral (Cowper’s glands) and the urethral glands. The size and weight of the glands are affected significantly by the age of the animal, (tending to reach a maximum between 10.5 - 15 years) and the season. They are largest during the breeding season. This is concomitant with the increased activity and size of the testis. That suggests that the activities of the accessory sex glands are regulated by androgen secretion from the testis. | The most important feature is the absence of seminal vesicles in the Camelidae family.
