WebSpermatogenesis takes place in the seminiferous tubules. This includes mitosis and meosis to form haploid gametes, followed by maturation to form spermatocytes (called spermiogenesis). The stages that a developing spermatogonium passes through as it develops and matures to form a mature spermatozoon are covered in more detail here.

Spermatogenesis takes place within several structures of the male reproductive system. The initial stages occur within the testes and progress to the epididymis where the developing gametes mature and are stored until ejaculation.
