Physiology of epididymis


Sperm cells  acquire their ability for locomotion in the epididymis especially at the tail of the epididymis hence it is believed that epididymal maturation is paramount for fertilizability of the sperm cell. The processes of maturation which occurs in the epididymis are chemical in nature, glycoproteins are produced in the epithelium of the epididymis which aid maturational process of the sperm cell. But the maturation which occurs in the epididymis are of a chemical nature and not morphological. It is believed that these maturational processes act on the membrane modifying considerably the membrane chemistry and thus changing such chemical and physical properties of membrane such as membrane charges etc. Sperm cells which do not have the influence of epididymal environment cannot fertilize any egg. Epididymis is used for the storage of sperm so that during ejaculation it is usually the cells which are stored in the epididymis that are ejaculated.
