The rete testis (/ˈriti ˈtɛstɪs/) is an anastomosing network of delicate tubules located in the hilum of the testicle (mediastinum testis) that carries sperm from the seminiferous tubules to the efferent ducts. It is the counterpart of the rete ovarii in females. Its function is to provide a site for fluid reabsorption.
