Dec 04, 2018 · Epididymis: A structure within the scrotum that is attached to the back side of the testis. The epididymis is a coiled segment of the spermatic ducts that stores spermatozoa while they mature and then transports the spermatozoa between the testis and the tube connecting the testes with the urethra (vas deferens).Author: William C. Shiel Jr., MD, FACP, FACR. Apr 01, 2015 · The epididymis is a long, coiled tube that stores sperm and transports it from the testes. It appears as a curved structure on the posterior (back) margin of each testis. It is comprised of three.

Sperm made in the testis go into the head (caput) of the epididymis, go through the body (corpus) and stop at the tail (cauda), where they are stored. When sperm are first made and travel to the head, they are not yet ready to be ejaculated. They cannot swim or fertilize an egg. By the time they reach the tail, the sperm can fertilize an egg.MeSH: D004822. Nov 01, 2015 · The seminiferous tubules are lined with germ cells that produce sperm and nutrient fluid.

How long can sperm be stored in the epididymis? However, these cells are not mature when leaving the testicles and must finish their development in the epididymis. Answer and Explanation. Oct 09, 2017 · When sperm first enters the epididymis from the testis, it is very immature and diluted by a relatively large volume of liquid. The smooth muscle of the epididymis pushes the sperm along tubule with slow waves of peristalsis, so that the sperm traverse its entire 20-foot length in about two weeks.

The epididymis is a long coiled tube that sits on the back of the testes. When sperm is released from the testes it is too immature to contribute to fertilization. Therefore, the sperm enters the head of the epididymis where it is stored for up to a week while it continues to develop before completing maturation in the body of the epididymis.
