The two testes are the male sex organs that produce sperm and male hormones. Behind each testicle is a coiled tube called theepididymis. Sperm matures as they pass from the tesiticle through the epididymis. The testicles are formed near the kidneys. As the fetus grows in the mother's womb, the testicles move down through the groin into the scrotum. The scrotum is a sac of skin that covers the testicles. Blood vessels in the scrotum carry blood to and from the tesicles.
In addition to their role in the male reproductive system, the testes are also an endocrine gland because they secrete testosterone. While the location of the testes is vulnerable to injury, it provides a cooler temperature for the organs. A cooler enviroment is necessary for healthy sperm production.
