spermatogonium

 [sper″mah-to-go´ne-um] (Gr.)
an undifferentiated male germ cell, originating in a seminal tubule and dividing into two spermatocytes.

sper·ma·to·go·ni·um

(sper'mă-tō-gō'nē-ŭm),
The primordial male cell derived by mitotic division from the yolk sac that migrates into the developing testes. Subsequent to puberty, it differentiates by increasing several times in size to become a primary spermatocyte.
See also: spermatid.
[spermato- + G. gonē, generation]

spermatogonium

/sper·ma·to·go·ni·um/ (-go´ne-um) pl. spermatogo´nia   an undifferentiated male germ cell, originating in a seminiferous tubule and dividing into two primary spermatocytes.

spermatogonium

(spər-măt′ə-gō′nē-əm, spûr′mə-tə-)
n. pl. spermatogo·nia (-nē-ə)
Any of the cells that give rise through mitosis to the spermatocytes and are found in the testes of vertebrates.

spermatogonium

[-gō′nē·əm] pl. spermatogonia
Etymology: Gk, sperma + gone, generation
a male germ cell that gives rise to a spermatocyte early in spermatogenesis.

sper·ma·to·go·ni·um

, spermatogone (spĕr'mă-tō-gō'nē-ŭm, -mă-tō-gōn)
The undifferentiated male sex cell derived by mitotic division from a primordial germ cell; increasing several times in size, it becomes a primary spermatocyte.
See also: spermatid

spermatogonium

an early diploid stage of male GAMETO GENESIS.

Spermatogenic cell series in seminiferous tubule wall, spermatogonium, primary spermatocytes, spermatid cell, and Sertoli cell were found normal and comparable to the untreated control (Figure 4a-d).
The process begins when a type A1 spermatogonium divides to generate two type A2 spermatogonia.
This is the longest phase of spermatogenesis, accounting for as much as 30 percent of the time required for a spermatogonium to develop into a spermatozoon.
As it is shown in table 3, spermatogonium significantly increased in the HFD+A group (p < 0.
The spermatogonium is a large, oval-shaped structure ranging from 5-7 [micro]m in diameter, and it contained a clear nucleus with small areas that stained light blue as a result of uncoiled euchromatin (Fig.
In males, examination of nuclear characteristics and cell size revealed that the germ cells could be classified into four stages: spermatogonium, spermatocyte, spermatid, and spermatozoa.
They are spermatogonium, 5 stages of primary spermatocyte, secondary spermatocyte, 2 stages of spermatid and spermatozoa (Fig.
