where is the scrotum located on a male?
under the penis
the scrotum is an anatomical male reproductive structure that consists of a suspended dual-chambered sack of skin and smooth muscle that is present in most terrestrial male mammals and located under the penis. one testis is typically lower than the other to avoid compression in the event of impact. the perineal raphe is a small, vertical, slightly raised ridge of scrotal skin under which is found the scrotal septum. it appears as a thin longitudinal line that runs front to back over the entire scrotum. the scrotum contains the external spermatic fascia, testes, epididymis, and ductus deferens. it is a distention of the perineum and carries some abdominal tissues into its cavity including the testicular artery, testicular vein, and pampiniform plexus. in humans and some other mammals, the scrotum becomes covered with pubic hair at puberty. the scrotum will usually tighten during penile erection and when exposed to cold temperature.

having the scrotum and testicles situated outside the abdominal cavity may provide additional advantages. the external scrotum is not affected by abdominal pressure. this may prevent the emptying of the testes before the sperm were matured sufficiently for fertilization. another advantage is it protects the testes from jolts and compressions associated with an active lifestyle. animals that move at a steady pace – such as elephants, whales, and marsupial moles – have internal testes and no scrotum. unlike placental mammals, some male marsupials have a scrotum that is anterior to the penis, although there are several marsupial species without an external scrotum. in humans, the scrotum may provide some friction during intercourse, helping to enhance the activity.
