A structure within the scrotum attached to the backside of the testis and whose coiled duct provides storage, transit and maturation of spermatozoa.
An oblong-shaped body attached to each testicle in which sperm cells mature and are stored.
Cordlike structure along border of testis.
A long twisting thin tube at the back of the testis, which forms part of the efferent duct of the testis, and in which spermatozoa are stored before ejaculation.
The area behind the testes, including a long coiled tube where a man’s sperm mature.
Long, coiled tube along the back side of the testis that connects the seminiferous tubules of the testis to he vas deferens. Sperm mature as they pass through the epididymis and are then stored before ejaculation.
A long, coiled duct that carries sperm from the seminiferous tubules of the testes to the vas deferens.
A twisted or convoluted duct, attached to the back side of each testicle within the scrotum. The epididymis, about 20 feet long, connects the vas deferens (tube emerging from the testicle) with the vas deferens (a tube or duct leading into the urethra). Sperm produced in the testicle move into and through the epididymis, where they mature over the next 10 to 20 days until they have the ability to move and fertilize an egg if released.
A highly convoluted tube, about seven meters long, that connects the ‘testis to the vas deferens. The spermatozoa are moved passively along the tube over a period of several days, during which time they mature and become capable of fertilization. They are concentrated and stored in the lower part of the epididymis until ejaculation.
An oblong body attached to the upper part of each testicle, composed of convoluted vessels and ducts, that connects the vasa efferentia to the vas deferens. Sperm cells produced in the testis pass along the epididymis, maturing as they go, to be stored in the seminal vesicles until ejaculation occurs. The epididymis may be damaged by trauma or infection resulting sometimes in sterility. Cysts may also occur.
A small oblong organ resting on and beside the posterior surface of a testis, consisting of a convoluted tube 13 to 20 ft (3.97 to 6.1 m) long, enveloped in the tunica vaginalis, ending in the ductus deferens. It consists of the head (caput or globus major), which contains 12 to 14 efferent ducts of the testis, the body, and the tail (cauda or globus minor). It is the first part of the secretory duct of each testis. The epididymis is supplied by the internal spermatic, deferential, and external spermatic arteries; it is drained by corresponding veins.
A J-shaped tube located on the back of each testis, in which sperm are stored for two to four days after they are formed.
The conduit connecting the testicle and the vas deferens, facilitating the transit of spermatozoa.
The epididymis is a lengthy, spiraled tube positioned at the back of the testicle. It functions as a connection between the vasa efferentia (small channels coming from the testicle) and the vas deferens (the sperm conduit that connects to the urethra). The testis produces sperm cells that mature gradually as they move through the epididymis. This maturation process readies the sperm for the potential fertilization of an egg. Once the sperm cells have fully matured, they are stored in the epididymis until they are released during ejaculation.
Conditions that can affect the epididymis include epididymal cysts, which are fluid-filled lumps in the epididymis, and epididymo-orchitis, a condition characterized by inflammation in both the testicle and the epididymis. Damage or infection can lead to a blockage in the epididymis, and if this happens in both testicles, it could potentially result in infertility.
A compact formation located above and behind each testicle, forming part of the seminal pathway.
