Where Do Spermatogenesis Occur?

As mentioned above, spermatogenesis is the process by which sperm cell production occurs; the germ cells give rise to the haploid spermatozoa. Sperm production takes place inside the seminiferous tubules

seminiferous tubules
During spermatogenesis, the DNA of spermatogenic cells in the seminiferous tubules is subject to damage from such sources as reactive oxygen species. The genomic integrity of spermatogenic cells is protected by DNA repair processes. Deficiencies in the enzymes employed in these repair processes may lead to infertility.

, which is a convoluted cluster of tubes located inside the testes.

Where does spermatogenesis occur in the body?

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.

Where do spermatogenesis and Spermiogenesis occur?

The entire process of spermatogenesis, spermiogenesis included, occurs in the coiled tubules called seminiferous tubules within the testes. After spermiogenesis, the non-motile spermatozoa leave the seminiferous tubule to reach the epididymis where it will become motile and stored for later release.
