Epididymis
The epididymis is part of the male reproductive system. It is a coiled tube-like structure that is 6 meters in length located posteriorly at the margin of the testes. The epididymis is attached to the tubes in the testes. This allows the sperms to travel from the testes going to the epididymis for storage and maturation process.

Epididymis
The internal lining of the wall of the epididymis is consists of columnar cells, which are believed to produce glycogen. As source of cellular energy, this glycogen supply keeps the stored sperms in the epididymis alive.
Initially, the sperm cells coming from the testes are immobile. As they move to the epididymis and matures, they develop their flagella, a whip-like structure that allow them to propel themselves independently after ejaculation. Through this, sperms can swim towards the matured egg cell of the female for fertilization.
3 Sections of the Epididymis:
1. head
2. body
3. tail
The head of the epididymis lies at the superior pole of each testis. This is the section where the sperm are stored and prepared for maturation. The body of the epididymis, is a long and twisted tube. It is where the actual sperm maturation takes place. The tail of the epididymis, is attached to the ductus deferens or vas deferens, another tube-like structure that is connected to the ejaculatory ducts.
