Intratesticular ducts
These images show the posterior region of the testis where the rete testis exits. Sperm produced in the seminiferous tubules are moved into the rete testis in the mediastinum by peristaltic contractions of the tunica propria along the length of the seminiferous tubules. Sperm are passively transported in the rete testis by the flow of testicular fluid onto the efferent ductules. 10x, 100x
