The process of oogenesis starts in the fetal ovaries with the development of oogonia from primordial germ cells (PGCs). Oogonia are formed during fetal development (in the process called oocytogenesis), and divide via mitosis, much like spermatogonia in the testis. In other words, primary oocytes reach their maximum ...
WebSpermatogenesis is an elaborate cytological process by which spermatogonia give rise to sperm. In anamniotes, temporal spermatogenesis occurs within a cyst in which a cohort of germ cells progress through the phases of spermatogenesis. All the germ cells present in a cyst are in the same stage of spermatogenesis. WebIt gives rise to two cells of unequal sizes. _9. Spermatocytes are produced throughout the lifetime of the male.
