Editing Rete testis (section)

===Development===
In the [[development of the urinary and reproductive organs]], the [[testis]] is developed in much the same way as the [[ovary]], originating from [[mesothelium]] as well as [[mesonephros]]. Like the ovary, in its earliest stages it consists of a central mass covered by a surface epithelium. In the central mass, a series of cords appear. These cords run together toward the future [[hilum (anatomy)|hilum]] and form a network that ultimately becomes the rete testis.
