The Scrotum
The scrotum is a sac of skin containing the testes and their outer layers. In male ruminants the scrotum is long and pendulous with a marked neck. In the stallion it is more globular with a poorly defined neck.
In these animals the scrotum lies ventral to the cranial pelvis. The scrotum of the boar is almost subanal and is not well-defined, as it lies close against the caudal surface of the thighs. In the dog the scrotum is situated between the thighs and towards the anus. In the cat the scrotum is subanal.The arterial supply of the scrotum is provided by branches of the external pudendal artery, and the nerve supply originates from the second and third lumbar (third and fourth in the dog) nerves with a small contribution from the preputial and scrotal branch on the pudendal nerve.
