The epididymis (/ ɛ p ɪ ˈ d ɪ d ɪ m ɪ s /; pl.: epididymides / ɛ p ɪ d ɪ ˈ d ɪ m ə d iː z / or / ɛ p ɪ ˈ d ɪ d ə m ɪ d iː z /) is an elongated tubular genital organ attached to the posterior side of each one of the two male reproductive glands, the testicles.
The initial segment of the epididymis, first described in the guinea pig epididymis, [10] is a histologically distinct region of tall pseudostratified columnar epithelium that receives spermatozoa from the ductuli efferentes (Figure 1). The epididymis is the primary sperm storage organ in male reptiles. [6]

In human anatomy, the penis (/ ˈ p iː n ɪ s /; pl.: penises or penes; from the Latin pēnis, initially "tail" [1]) is an external sex organ (intromittent organ) through which males urinate and ejaculate.
The epididymis is a long whitish mass of tightly coiled tube. The sperm that are produced in the seminiferous tubules flow into the epididymis. During passage via the epididymis, the sperm undergo maturation and are concentrated by the action of ion channels located on the apical membrane of the epididymis. [2]
The human vas deferens measures 30–35 cm in length, and 2–3 mm in diameter. [3]: 1297 It is continuous proximally with the tail of the epididymis, [3]: 1296 and exhibits a tortuous, convoluted initial/proximal section (which measures 2–3 cm in length).
Epididymal cysts is a mass that forms in the epididymis. [10] These cysts differ from spermatoceles as they contain clear fluid, rather than seminal fluid. In addition, spermatoceles are more likely to be found on the head of the epididymis. [19] Other abnormalities can be detected during male genital examination including Peyronie's disease.
Spermatogenesis, the process for producing spermatozoa, takes place in the seminiferous tubules.During spermatogenesis, the DNA of spermatogenic cells in the seminiferous tubules is subject to damage from such sources as reactive oxygen species. [1]
