The testes are the primary male sexual organs in that they make sperm and produce testosterone. The sperm is the male sex cell, or gamete, and each testicle produces more than 4 million new sperm per hour [source: Angier ]. Testosterone is the hormone that causes male secondary sex characteristics such as facial and pubic hair, thickened vocal cords and developed muscles. The testes are housed outside of the main part of the male's body, in a sac called the scrotum. This location is important because in order for the sperm to develop properly, they must be kept at a temperature about two degrees cooler than normal body temperature. It takes sperm about 4 to 6 weeks to mature, which they do as they travel from each testis to a coiled tube on the outer surface of each testis called the epididymis. Sperm, which are often compared to tadpoles in appearance, use their tails to travel, while the head contains the genetic material.
