Spermatogenesis inhuman
- Spermatogenesis in man occurs in the testis;
- Primordial germ cells (2n) divide mitotically to form spermatogonia that grow into primary spermatocyte (gamete forming cells) with 46 chromosomes
- Primary spermatocytes undergo the first meiotic division to form two secondary spermatocytes (n), each with 23 chromosomes.
- The secondary spermatocyte undergoes a second meiotic division to produce spermatids (n), each with 23 chromosomes.
- Spermatids then differentiate into sperms (spermatozoa).
- The process of meiosis in male always result in four cells that become sperms.
