The rete testis (/ˈrti ˈtɛstɪs/ REE-tee TES-tis) 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.

The rete testis is the network of interconnecting tubules where the straight seminiferous tubules (the terminal part of the seminiferous tubules) empty. It is located within a highly vascular connective tissue in the mediastinum testis. The epithelial cells form a single layer that lines the inner surface of the tubules. These cells are cuboidal, with microvilli and a single cilium on their surface.
