Spermatogenesis at a glance. Spermatogenesis is the process by which male gametes develop from germ cells in the testes. In other words, it's how sperm is made. This process involves multiple steps of cell division and differentiation, which are summarized in the image below. [What are 'n' and '2n'?]

Tahapan spermatogenesis secara berurutan adalah spermatogonium, spermatosit primer, spermatosit sekunder, spermatid, dan sperma. Secara umum, tahap pembentukan sperma ini meliputi 2 proses, yaitu: 1. Spermatositogenesis. Tahap ini disebut juga dengan tahap pembelahan mitosis dan meiosis, yang berlangsung dari spermatogonium (2n) menjadi.

Spermatogenesis is the production of sperm from the primordial germ cells. Once the vertebrate PGCs arrive at the genital ridge of a male embryo, they become incorporated into the sex cords. They remain there until maturity, at which time the sex cords hollow out to form the seminiferous tubules, and the epithelium of the tubules differentiates.

The union of male and female gametes creates offspring. The production of these vital reproductive cells occurs in the testis and ovary during the processes of spermatogenesis and oogenesis, respectively.[1] The primary male reproductive organs, the testes, are located inside the scrotum and function to produce sperm cells as well as the primary male hormone, testosterone. As mentioned above.

The Niche. The architecture of the testes is characterized by two structurally distinct compartments (Figure 1), the seminiferous tubule and the interstitial tissue ().Within the seminiferous tubule, Sertoli cells form a tight blood-testis barrier to divide the seminiferous epithelium into basal and luminal compartments ().Developing spermatogonia reside on the basal membrane and are further.

spermatogonium: Any of the undifferentiated cells in the male gonads that become spermatocytes. Spermatogenesis is the process by which male primary sperm cells undergo meiosis and produce a number of cells calls spermatogonia, from which the primary spermatocytes are derived. Each primary spermatocyte divides into two secondary spermatocytes.

In the heteronymous division the cytoplasmic division is not completed; the daughter cells stay bound together through thin cytoplasmic bridges. Also in the subsequent meiosis the cytoplasmic division is incomplete, so that from one spermatogonium a network of daughter cells arises that doubles in size in each generation. The forming of such networks assures that all of the processes in each.

A spermatogonium (pl.: spermatogonia) is an undifferentiated male germ cell.Spermatogonia undergo spermatogenesis to form mature spermatozoa in the seminiferous tubules of the testis.. There are three subtypes of spermatogonia in humans: Type A (dark) cells, with dark nuclei. These cells are reserve spermatogonial stem cells which do not usually undergo active mitosis.
Diagrama De Espermatogenesis
In mammals, spermatogenesis is maintained throughout life by a small subpopulation of type A spermatogonia called spermatogonial stem cells (SSCs). In rodents, SSCs, or Asingle spermatogonia, form the self-renewing population. SSCs can also divide into Apaired (Apr) spermatogonia that are predestined to differentiate.
