Rete testis 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 vasa efferentia.
Rete tubular ectasia is a disorder of the rete testis in which many benign cysts are present.
In the area of the rete testis, the sperm are concentrated as fluid and is reabsorbed. If this does not occur, the sperm which enter the epididymides are not concentrated and infertility is the end result.
