It is a single, narrow, tightly-coiled tube in adult humans, six to seven meters in length [1] connecting the efferent ducts from the rear of each testicle to its vas deferens. Play party (BDSM) In reptiles, there is an additional canal between the testis and the head of the epididymis and which receives the various efferent ducts. This is, however, absent in all birds and mammals. The epididymis is covered by a two layered pseudostratified epithelium. The epithelium is separated by a basement membrane from the connective tissue wall which has smooth muscle cells. The major cell types in the epithelium are:. The stereocilia of the epididymis are long cytoplasmic projections that have no motility and which aid in absorption.Sperm are stored in the epididymis until fully developed.

In the types of sexual reproduction known as anisogamy and its subtype oogamy , there is a marked difference in the size of the gametes with the smaller one being termed the "male" or sperm cell. A uniflagellar sperm cell that is motile is referred to as a spermatozoon , whereas a non-motile sperm cell is referred to as a spermatium. Sperm cells cannot divide and have a limited life span, but after fusion with egg cells during fertilization, a new organism begins developing, starting as a totipotent zygote. The human sperm cell is haploid , so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell. In mammals , sperm develops in the testicles , stored in the epididymis , and is released from the penis.
