Seminiferous tubules of testes
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. WebWithin the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis. Epididymis. The epididymis is a long, coiled tube that rests on the backside of each testicle. It carries and stores sperm cells that are created in the testes.
