give a labeled diagram of spermatogenesis as im finding it difficult to understand .


  • In males, sperms are produced by the spermatogonia (immature germ cells), which are present in the inner walls of the seminiferous tubules.

  • Spermatogonia increase in number by mitosis. These are diploid.

  • Some of the spermatogonia called primary spermatocytes periodically undergo meiosis.

  • After the first meiotic division, two haploid and equal secondary spermatocytes are formed.

  • These further undergo meiosis to give rise to four haploid spermatids.

  • These spermatids are converted into sperms by spermiogenesis.

  • The sperm head gets embedded in the Sertoli cells after spermiogenesis and is released from the seminiferous tubules by spermiation.
