The epididymis is a coiled network of tubes. The epididymis is lined with pseudostratified columnar epithelial with stereocilia. Stereocilia get their name because scientists first thought that these were cilia. In reality, they are microvilli which increase the surface area of the inside of the tube. The job of these cells is to release nutrients and other factors that aid with sperm maturation. Other basal cells are present. It is thought that these replace the columnar cells.
