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

Spermatogenesis

• 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.
