Rete testis

Latin eponym: Rete Halleri
Eponym: Haller's rete

The tubuli recti enter the fibrous tissue of the mediastinum, and pass upward and backward, forming, in their ascent, a close net-work of anastomosing tubes which are merely channels in the fibrous stroma, lined by flattened epithelium, and having no proper walls; this constitutes the rete testis.

At the upper end of the mediastinum, the vessels of the rete testis terminate in from twelve to fifteen or twenty ducts, the ductuli efferentes; they perforate the tunica albuginea, and carry the seminal fluid from the testis to the epididymis.
