WebSeminiferous Tubules. Spermatogenesis takes place within the seminiferous tubules, which, in humans, are ~200 μm in diameter and have a total length of ~600 meters occupying ~60% of the testis volume (Fig. 136-1). The terminal ends of the seminiferous tubules in the mediastinum empty via straight tubular extensions termed tubuli recti.
