It is a partially coiled tube which ascends into the abdomen through the inguinal canal . </P> <P> There are two ducts, connecting the left and right epididymis with the seminal vesicles to form the ejaculatory duct in order to move sperm . In humans, each tube is about 30 centimeters (1 ft) long, 3 to 5 mm in diameter and is muscular (surrounded by smooth muscle). Its epithelium is pseudostratified columnar epithelium lined by stereocilia . </P>
