<P> In the embryo, the epididymis develops from tissue that once formed the mesonephros, a primitive kidney found in many aquatic vertebrates . Persistence of the cranial end of the mesonephric duct will leave behind a remnant called the appendix of the epididymis . In addition, some mesonephric tubules can persist as the paradidymis, a small body caudal to the efferent ductules . </P> <P> A Gartner's duct is a homologous remnant in the female . </P> <P> Spermatozoa formed in the testis enter the caput epididymis, progress to the corpus, and finally reach the cauda region, where they are stored . Sperm entering the caput epididymis are incomplete--they lack the ability to swim forward (motility) and to fertilize an egg . It stores the sperm for 2--3 months . During their transit in the epididymis, sperm undergo maturation processes necessary for them to acquire these functions . Final maturation is completed in the female reproductive tract (capacitation). </P> <P> The epididymis secretes some proteins that blocks the receptors on the plasma membrane of sperm head which renders sperm infertile inside the male tract (decapacitation). </P>

Where is mature sperm stored in the epididymis
