The Mediastinum Testis:

The mediastinum testis is the thickened area of connective tissue which lies at the posterior aspect of the testis
Connective tissue septae extend from the mediastinum testis to subdivide the testis into lobules
The open ends of the seminiferous tubules are continuous with the proximal parts of the excretory portions of the male genital tract
Within the substance of the mediastinum testis lies the first part of the excretory duct system of the testis - the rete testis
The rete testis is an interconnecting labyrinth of epithelial lined spaces which acts as a sink for the spermatozoa produced in the seminiferous tubules
From the rete testis, the spermatozoa are passes into the ductuli efferentes which pass out of the postero-superior part of the mediastinum testis
