Sperm duct During mating, sperm cells that have been released pass through the sperm ducts. Testes There are two testes (one of them is called a testis). In cartilaginous fish and amphibians, sperm is carried through the archinephric duct, which also partially helps to transport urine from the kidneys. In teleosts, there is a distinct sperm duct, separate from the ureters, and often called the vas deferens, although probably not truly homologous with that in humans.Artery: Superior vesical artery, artery of the ductus deferens.

The sperm that passes through the sperm ducts is not yet motile and therefore it must be transported through peristalsis with the help of the muscle tissue that lines the walls of the sperm ducts. When the sperm reaches the far end of the sperm ducts it can be stored in the ampulla (cavity or a dilated end of a duct) to await ejaculation. Start studying Exercise 58.
