Epididymis
The epididymis (pl., epididymides) is a comma-shaped structure, about 3.8 cm (1.5 in) long, that lies along the posterior surface of each testis (Figures 4.2 and 4.8). As the vasa efferentia leave the testis, they enter the larger, upper portion (“head”) of the epididymis. The vasa efferentia then join to form a single, coiled ductus epididymis in the middle region (“body”) of the epididymis. This duct then enlarges to form the beginning of the vas deferens in the “tail” region of the epididymis. Tubules within the epididymis secrete important substances that help the sperm survive and mature. While in the body of the epididymis, sperm are nurtured by epididymal secretions and undergo further stages of their maturation. For example, human sperm taken from the head portion of the epididymis can swim, but only in a circle. In contrast, those taken from the body of the epididymis can move forward by swimming in a spiral path.

GROSS ANATOMY
The epididymis is a single tubule that connects the efferent ductules to the vas deferens and plays important roles in sperm transit, maturation, and storage. The structure identifiable grossly as the epididymis contains the efferent ductules, the highly convoluted epididymal tubule, and the surrounding connective tissue. The epididymis is conventionally divided into three contiguous regions based on gross appearance: the caput, the corpus, and the cauda epididymis. The caput epididymisextends over and is firmly attached to the cranial pole of the testicle. The corpus epididymis lies horizontally, dorsal to the testicle and lateral to the spermatic cord. The cauda epididymis is firmly attached to the caudal pole of the testicle by the proper ligament of the testis and to the parietal vaginal tunic by the ligament of the tail of the epididymis, both of which are remnants of the fetal gubernaculum (Figure 27-1).

Completion of your question is given below
Which of the following describes the epididymis?
A. a tube that transports sperm to the urethra
B. a vesicle that produces fluid and gives sperm nourishment and motility
C. A gland that contributes fluid to semen
D. A tube that stores and develops sperm cells from the testes
The answer for your question is option (A)- a tube that transports sperm to the urethra.
Epididymis is a coiled tube that lies behind each testicle. Main function of this coiled tube is to store and transport the sperm cells from testicles.
