What is the other name of spermiogenesis?

What is the other name of spermiogenesis?

The process is called spermatogenesis. It occurs in the seminiferous tubules of the male gonad (testis). In mammals, the male germ cells include the spermatogonium, the spermatocyte, and the spermatid.

What is meant by Spermatocytogenesis?

Spermatocytogenesis is the male form of gametocytogenesis and involves stem cells dividing to replace themselves and to produce a population of cells destined to become mature sperm. The stem cells involved are called spermatogonia and are a specific type of stem cell known as gametogonia.

What is the difference between spermiogenesis and spermiation?

In spermiogenesis, spermatozoa are formed , while in spermiation spermatozoa are released from sertoli cells into the cavity of seminiferous tubules. …

What is the other name of Sertoli cells?

Sertoli cells, also called sustentacular cells, are approximately pyramid-shaped cells lying within the seminiferous epithelium (Figure 4.3). Their bases lie against the basement membrane of each tubule, and their tips point toward the cavity in the middle of each tubule.

What happens in Spermiation?

Spermiation is the process by which mature spermatids are released from Sertoli cells into the seminiferous tubule lumen prior to their passage to the epididymis. The molecular composition of the spermiation machinery, its dynamic changes and regulatory factors are examined.

What is the difference between spermatogenesis and spermatocytogenesis?

Sperms are the male gametes produced in the seminiferous tubules of the testes. The main difference between spermatogenesis and spermiogenesis is that spermatogenesis is the formation of sperm cells whereas spermiogenesis is the maturation of the spermatids into sperm cells.

What is the role of FSH in Spermiation?

Attention is focused on the action of FSH during neonatal development, puberty, and adulthood. The mechanism whereby the circulating concentration of FSH regulates spermatogonial proliferation to dictate the sperm production rate under physiological conditions in the adult is discussed in detail.

What is the difference between spermiogenesis and capacitation?

Spermiogenesis the process by which spermatids become spermatozoa. Capacitation is the process by which spermatozoa become motile and are fully mature; this does not occur until they are in the female reproductive tract.

What are defects in spermiogenesis and spermiation?

Defects in spermiogenesis and spermiation are manifested as low sperm number, abnormal sperm morphology and poor motility and are commonly observed during reproductive toxicant administration, as well as in genetically modified mouse models of male infertility.

What is a synonym for defects?

Synonyms for defects. blemishes, blights, blotches, deformities, disfigurements, excrescences, excrescencies, faults,

What is the process of spermiation?

Spermiation is the process by which mature spermatids are released from Sertoli cells into the seminiferous tubule lumen prior to their passage to the epididymis.

What is the final remodelling of the mature elongated spermatid?

The final remodelling of the mature elongated spermatid occurs during spermiation, when the spermatids line up along the luminal edge, shed their residual cytoplasm and are ultimately released into the lumen.
