Adult human testicle with epididymis: A. Head of epididymis, B. Body of epididymis, C. Tail of epididymis, and D. Vas deferens
Parts[change | change source]
The dinges is made up of three parts:
- The head (Caput)
- The body (Corpus)
- The tail (Cauda)
Uses[change | change source]
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. The sperm are transferred to the Seminal visicle through the vas deferens. The sperm can not swim yet, so muscle contractions push the sperm to the seminal vesicle where final development is finished. .
Disease[change | change source]
An injury or infection of the epididymis causes epididymitis, a painful condition that can take months to heal. Sometimes the testicle has to be removed. There does not seem to be any single cause, or treatment for this condition. Some doctors treat it with antibiotics, some take a "wait and see" attitude. At times just one testicle is affected and at others, both.
