- n. a convoluted tubule in each testis; carries sperm to vas deferens
The epididymis is a very tiny, tightly coiled tubule, which runs along the back of the testicle from top to bottom.
This tunic or coat sends fibrous partitions into the testis which divide the organ into lobules, each one being conical in shape with the apex directed towards the epididymis, which is that mass of blood vessels and tissues which one can feel on one side of each testis.
Upon the outside of the testicle, the tube or duct is found twisted and forming a slight bunch, known as the epididymis, _f_, _g_, _h_.
On the head of the epididymis is a second small stalked appendage (sometimes duplicated); it is named the appendix of the epididymis (pedunculated hydatid), and is usually regarded as a detached efferent duct.
Through the wall of the scrotum on either side the testis can be palpated; it lies toward the back of the scrotum, and along its posterior border the epididymis can be felt; passing upward along the medial side of the epididymis is the spermatic cord, which can be traced upward to the subcutaneous inguinal ring.
2. Mature sperm can wait up to two weeks in a holding area called the epididymis before they make their debut.
Infection sometimes spreads to the epididymis (the tube that carries sperm from the testis), causing pain, fever, and, rarely, sterility.
About half of the men with nongonococcal urethritis NGU, that is, inflammation of the urethra not due to gonorrhea, and almost half of those with acute infections of the epididymis, are infected with chlamydia.
Shining a light through the epididymis helps locate any firm, smooth cysts in the epididymis, which are almost always located on the top of the epididymis and are never malignant.
Mobile, small, hard bodies floating within the membrane covering the front and sides of the testicles and the epididymis are never malignant.
