the tests and sperm are located within the scrotum which is located on the outside of the male body to regulate a temperature adequate for sperm production

. The scrotum helps to keep the testes at a slightly lower temperature than the rest of the body, as sperm production is most efficient at slightly lower temperatures. The muscles in the scrotum can adjust to bring the testes closer to the body to retain heat or move them further away to cool down.

The testes produce sperm as well as testosterone, the male sex hormone. Sperm is released from the testes and travels through a tube called the vas deferens to the urethra, where it mixes with seminal fluid from the seminal vesicles and prostate gland to form semen.

The scrotum also protects the testes from injury and serves as a sensory organ that responds to touch and temperature changes. It is important to regularly check the scrotum for any lumps, swelling, or changes in size, as these could be signs of a medical issue such as testicular cancer.
