Related to spermatocyte: secondary spermatocyte, primary spermatocyte

spermatocyte

 [sper-mat´o-sīt]
the mother cell of a spermatid.
primary spermatocyte the original large diploid cell into which a spermatogonium develops; it can later undergo the first meiotic division into the secondary spermatocyte.
secondary spermatocyte a haploid cell produced by meiotic division of the primary spermatocyte; it can then develop into the spermatid.

sper·ma·to·cyte

(sper'mă-tō-sīt'),
Parent cell of a spermatid, derived by mitotic division from a spermatogonium.
[spermato- + G. kytos, cell]

spermatocyte

/sper·ma·to·cyte/ (sper-mat´o-sīt) a cell developed from a spermatogonium in spermatogenesis.spermatocy´talspermatocyt´ic
primary spermatocyte  a diploid cell that has derived from a spermatogonium and can subsequently begin meiosis and divide into two haploid secondary spermatocytes.
secondary spermatocyte  one of the two haploid cells into which a primary spermatocyte divides, and which in turn gives origin to spermatids.

spermatocyte

(spər-măt′ə-sīt′, spûr′mə-tə-)
n.
A diploid cell that undergoes meiosis to form four spermatids. A primary spermatocyte divides into two secondary spermatocytes, which in turn divide to form the spermatids.

spermatocyte

[spur′mətōsīt′]
Etymology: Gk, sperma + kytos, cell
a male germ cell that arises from a spermatogonium. Each spermatocyte gives rise to two haploid secondary spermatocytes that become spermatids.

sper·ma·to·cyte

(spĕr-mat'ō-sīt)
Parent cell of a spermatid, derived by mitotic division from a spermatogonium.
[spermato- + G. kytos, cell]

spermatocyte

A cell of the seminiferous tubules of the testis that is converted by MEIOSIS into four SPERMATIDS.

spermatocyte

a diploid or haploid stage in male GAMETOGENESIS.

spermatocyte

the mother cell of a spermatid.

primary spermatocyte
daughter cell of a spermatogonium (an incongruous nomenclature in such an intensely masculine context). It undergoes the first meiotic division.
secondary spermatocyte
a cell produced by meiotic division of the primary spermatocyte, and which gives rise to the spermatid.

The current European Association of Urology recommendations for the reporting of a testicular biopsy include (1) absence of seminiferous tubules (seminiferous tubule hyalinization), (2) presence of Sertoli cells only (Sertolicell-only syndrome), (3) maturation arrest--incomplete spermatogenesis, not beyond the spermatocyte stage, and (4) hypospermatogenesis--all cell types up to spermatozoa are present, but there is a distinct decline in the number of reproducing spermatogonia.
Interpretation & conclusion: The accumulation of early primary spermatocytes is an indication that progression of meiosis is defective in spermatogenesis failures.
The most important ultrastructural features are prominent nucleolus with dispersed nucleolonema and specialized cell junctions of the zonula adherens type, true intercellular bridges, identical to those normally found between spermatocytes and between spermatids.
Population of preleptotene, pachytene, secondary spermatocytes and step-19 spermatid were declined by 60.
Moreover, the number of spermatocyte, Sertoli cells, sperm count, viability, motility and normal morphology in the HFD+A group was significantly higher than the HFD group.
According to Table 1 it can be seen that sulfasalazine caused a significant reduction in the number of spermatogonia, primary spermatocytes but Vitamin E and C combined together have significantly increased in all experimental groups compared to the control group (Figures 1 to 5).
In 18-mo-old males, spermatogonia and primary spermatocytes were identified, whereas in 24-too-old males, all cell stages of spermatogenesis were present.
For calculation the TDI from percent of seminiferous ducts that these ducts are consist of interstitial spermatogony, B-type spermatogony, spermatocyte and spermatide were used.
Using the criteria defined by Smith (1959) and Sadovy and Shapiro (1987), we considered individuals with gonads containing primarily ovarian tissue, degenerating or not, with few clusters of spermatocytes, spermatids, or spermatozoa to be undergoing sexual inversion.
