A hilar testicular network that collects produced sperm from the seminiferous tubules, and connects with the efferent ducts.
The rete testis is the network of interconnecting tubules where the straight seminiferous tubules (the terminal part of the seminiferous tubules) empty (Pic. 1). It is located within a highly vascular connective tissue in the mediastinum testis (Pic. 2).
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 (Pic. 3).
