Where does sperm develop in the male reproductive system?

Sperm develops within the seminiferous tubules of the testes. These tubules are highly coiled structures located inside the testes where spermatogenesis occurs, a complex process that begins with spermatogonia (the precursor germ cells) and results in the formation of mature sperm. The seminiferous tubules provide the appropriate environment for this development, including the presence of Sertoli cells, which support and nourish the developing sperm.

Once the sperm cells mature, they move to the epididymis, where they further gain motility and are stored until ejaculation. The prostate gland and scrotum do not play a direct role in sperm development; the prostate contributes to semen production and fluid composition, while the scrotum houses the testes and helps regulate their temperature. Thus, the seminiferous tubules are correctly identified as the primary site of sperm development in the male reproductive system.
