Anatomy anus scrotum

Organs of the male reproductive system. Many women report that too many men are hung up on the size of their penises. The function of the scrotum is to protect the testes and to keep them at a temperature several degrees below the normal body temperature. Nerves Cutaneous innervation to the scrotum is supplied via several nerves: It is dual-chambered, forming an expansion of the perineum. This fluid neutralizes the acidity within the urethra itself.

An additional function of scrotum appears to be the protection of testes and providing enough time for spermatozoa to mature before discharge. This is known as the perineal raphe. The skin of the scrotum in an adult male body is usually darker than the rest of the skin of the human body. The wall of the scrotum is made up of numerous layers.
