Gametogenesis may differ between males and females. Male gametes are called sperm. Female gametes are called eggs. In human males, for example, the process that produces mature sperm cells is called spermatogenesis. During this process, sperm cells grow a tail and gain the ability to "swim," like the human sperm cell shown in Figure below.
In contrast to postpubertal spermatogenesis, the early steps of germ cell development have only recently attracted attention, unveiling genes and pathways regulating SSC self-renewal and proliferation. Yet, less is known on the mechanisms regulating differentiation. The processes leading from gonocytes to spermatogonia have been seldom
Spermatocytogenesis is the first stage of spermatogenesis which involves the division of single diploid cells into four haploid spermatocytes. The testis is composed of numerous tightly coiled tubules called seminiferous tubules which are lined with stem cells. The immature cells called spermatogonia are formed from these stem cells.
The different generations of spermatogonia vary somewhat in the distribution of their heterochromatin. Type A (and earlier spermatogonia) are distinguished by a pale-staining nucleus with a fine "dusty" distribution of heterochromatin throughout the nucleus. Type B cells have dense clumps of heterochromatin around the periphery of the
Spermatogonium. It is a process in which spermatogonia undergo mitotic division to produce spermatocytes (primary and secondary spermatocytes), which in turn undergo meiosis to produce spermatids (round and elongating spermatids) which then further differentiate into spermatozoa (Roopnarine et al., 2021).
Discuss the differences and similarities between spermatogenesis and oogenesis; Gametogenesis, the production of sperm and eggs, takes place through the process of meiosis. called spermatogonia (singular: spermatagonium), go through mitosis with one offspring going on to differentiate into a sperm cell and the other giving rise to the next
