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.

Do castration and vasectomy have the same effects on the endocrine and reproductive functions?
Castration, removal or destruction of the testes, has a drastic effect of endocrine functions, as the testes are major sites of hormone production. As a vasectomy leaves the testes in tact, there is no effect on the endocrine system. Both methods prevent reproduction.
Why do males have two testes?
