The epididymis is a firm tube that lies on the back surface of each testicle. It is coiled in order to fit a length of nearly 20 feet into a small space. This long length acts as a storage space for the sperm and gives sperm time to mature.
The testes are the male gonads and contain hundreds of tiny seminiferous tubules where sperm cells are produced. The epididymis is a small oblong body which rests on the surface of the testes where sperm mature and are stored.he testes are the male gonads and contain hundreds of tiny seminiferous tubules where sperm cells are produced.
