Do cocks have balls?
Roosters do. They are internal and cannot be seen or felt from the outside. A rooster does not have an external scrotum, however, he does have testes. The testes are located high in the abdominal cavity just in front of the kidney and close to the backbone. The two kidney bean-shaped testes consist of many slender ducts. The lining of these ducts produces the sperm which is stored in a sperm sac. The testes shrink and grow on a regular basis, becoming larger during active mating. The left testis is often larger than the right one. In addition to creating sperm, the testes also produce the male hormones that influence mating, male behavior, the comb growth on their heads, the size of the tail feathers, the spurs on the insides of their feet and the red wattles under their chins.
Why does a bull's testicles hang lower from the body than a horse's?
There are two reasons why. First of all, horses are animals that love to run. In order to prevent the testes from getting damaged and bruised from running, they are tucked up closer to the body. Cattle are typically too bulky and heavy to run (though there is no doubt that they are capable of running quite fast), so the testes are allowed to hang down a bit more. The second reason is that the longitudinal length of the testes of a stallion are positioned parallel to the line of the underside of the belly or the ground. This prevents the scrotum from allowing the testes to hang down so much and, anatomically speaking, makes the testes have to be held closer to the body. With a bull, on the other hand, the testes are perpendicular to the ground.
What is the function of the urogenital system?
