What does Spermatogonium mean?
Medical Definition of spermatogonium : a primitive male germ cell that gives rise to primary spermatocytes in spermatogenesis. Other Words from spermatogonium. spermatogonial \ -nē-əl \ adjective.
What is the function of Spermatogonium?
Spermatogonia are the stem cells of the testis, which means that they are still able to differentiate into a variety of different cell types throughout adulthood. Spermatogonia divide to produce primary and secondary spermatocytes, then spermatids, which finally produce formed sperm.
What is spermatogenesis process?
Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis. The spermatids are transformed into spermatozoa (sperm) by the process of spermiogenesis. These develop into mature spermatozoa, also known as sperm cells.
How Spermatogonium is formed?
The immature cells (called spermatogonia) are all derived from cells called stem cells in the outer wall of the seminiferous tubules. The stem cells are composed almost entirely of nuclear material. (The nucleus of the cell is the portion containing the chromosomes.)
Are males born with Spermatogonium?
Yes, men are born with sperm. These precursors eventually become mature sperm after they reach puberty, which is similar to women producing mature eggs after they start menstruating.
How do you pronounce Spermatogonium?
noun, plural sper·mat·o·go·ni·a [spur-mat-uh-goh-nee-uh, spur-muh-tuh-].
What is the importance of spermatogenesis?
Spermatogenesis is required to maintain the fixed number of chromosomes in the individuals of a species. Sperms carry genetic information from one generation to the next generation. The spermatogonial stem cells can be used to preserve the genetic pool of endangered species.
What is spermatogenesis and oogenesis?
Gametogenesis, the production of sperm and eggs, takes place through the process of meiosis. The production of sperm is called spermatogenesis and the production of eggs is called oogenesis.
What is spermatogenesis simple?
: the process of male gamete formation including formation of a spermatocyte from a spermatogonium, meiotic division of the spermatocyte, and transformation of the four resulting spermatids into spermatozoa.
What is the function of the epididymis?
The epididymis is a long, coiled tube that rests on the backside of each testicle. It carries and stores sperm cells that are created in the testes. It’s also the job of the epididymis to bring the sperm to maturity — the sperm that emerge from the testes are immature and incapable of fertilization.
How many sperm are produced from Spermatogonium?
A single type B spermatogonium produces 2 primary spermatocytes by mitosis and each primary spermatocyte produces 4 sperms by meiosis. Therefore, a single type B spermatogonium produces 8 sperms.
What is difference between spermatogonia and Spermatogonium?
A spermatogonium (plural: spermatogonia) is an undifferentiated male germ cell. Spermatogonia undergo spermatogenesis to form mature spermatozoa in the seminiferous tubules of the testis….

Which is the best definition of a spermatogonium?
Definition of spermatogonium : a primitive male germ cell : a primitive male germ cell that gives rise to primary spermatocytes in spermatogenesis
Where does spermatogonia form in the male germ cell?
A spermatogonium (plural: spermatogonia) is an undifferentiated male germ cell. Spermatogonia undergo spermatogenesis to form mature spermatozoa in the seminiferous tubules of the testis.
What are the types of spermatogonial stem cells?
Type A (pale) cells, with pale nuclei. These are the spermatogonial stem cells that undergo active mitosis. These cells divide to produce Type B cells. Type B cells, which undergo growth and become primary spermatocytes.
How are spermatogonia cells able to repair DNA?
Experimental exposure of rat undifferentiated spermatogonia to doxorubicin and vincristine indicated that these cells are able to respond to DNA damage by increasing their expression of DNA repair genes, and that this response likely partially prevents DNA break accumulation.
