Part of epididymis responsible for storage of sperms is
The testes are paired ovoid structures that are housed in the scrotum and positioned so that the long axis is vertical. The testicle is covered by the tunica vaginalis. Beneath the tunica vaginalis is the capsule of the testis, termed the tunica albuginea. Seminiferous tubules continue to accessory ducts (vasa efferentia, epididymis, vas deferens, and rete testis) that transfers sperms from testes to ejaculatory ducts.
The caput, or head, is where sperm enter the epididymis from the testes. At this stage, sperm are not motile. They are also very dilute. The concentration of sperm starts in the caput.
The cauda epididymis is the primary storage site for mature sperm and is continuous with a highly muscular duct called the ductus deferens, also know as the vas deferens.
Vas deferens, also called ductus deferens, is a thick-walled tube in the male reproductive system that transports sperm cells from the epididymis, where the sperm are stored prior to ejaculation.
Gubernaculum is the fibrous cords that connect the fetal testis with the bottom of the scrotum.
