Detailed explanation-1: -For normal sperm development, the testes must be at a temperature slightly cooler than the body temperature. Special muscles in the wall of the scrotum allow it to contract (tighten) and relax, moving the testicles closer to the body for warmth and protection or farther away from the body to cool the temperature.
Detailed explanation-2: -The temperature is controlled by scrotal movement of the testes away or towards the body depending on the environmental temperatures. Moving the testes away from the abdomen and increasing the exposed surface area allow a faster dispersion of excess heat.
Detailed explanation-3: -First, it produces spermatozoa, the male gametes. Second, it synthesizes testosterone, the principal male sex hormone.
