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.
