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.

A) Testes from males [greater than or equal to] 90 mm SL contained all stages of spermatocyte development, including spermatozeugmata (10X; Mallory trichrome stain); B) Testes from smaller < 90 mm SL contained all stages of spermatocyte development, but no spermatozeugmata (20X; hematoxylin and eosin).
6: Synaptonemal complex abnormalities observed with the two fungicides Primary rat spermatocytes stained with an anti-SCP3 antibody were selected to observe the spermatocyte nuclei showing synaptonemal complex abnormalities by fluorescence photomicroscopy.
Administration of 100 mg/kg and 200 mg/kg to rats for 20 days significantly increased the number of stem cells and primary spermatocytes compared to control group [48].
Degeneration and necrosis of testicular germ cells, spermatogonia, spermatocytes, spermatids and spermatozoa, together with inhibition in sperm bundle formation was apparent after Lufox[TM] treatment; El Boki et al.
The arrest is most frequently observed at primary spermatocyte level but can occur at earlier or later levels.
Interpretation & conclusion: The accumulation of early primary spermatocytes is an indication that progression of meiosis is defective in spermatogenesis failures.
The actual number of primary spermatocytes produced during the proliferative phase is usually less than 64, due to cell death.
A total of 1066 surface-spread primary spermatocytes from 17 males (table 1) was analyzed from electron photomicro-graphs.
Our results showed that administration of 200 mg/kg bw of onion seeds extract for 28 days orally resulted in an increase of seminiferous tubules with normal spermatogenic cells and significant increase in the numbers of primary spermatocyte and spermatids, compared to diabetic control group.
As testosterone is the hormone responsible in male reproductive system [17], the prolonged low on blood testosterone levels is able to cause spermatogenic deficiencies [8], which detected in width of spermatocyte and spermatogonia layers treated with different concentrations of AB extract.
After examining 6 different areas, total number of labelled seminiferous tubules was calculated and proportion of the seminiferous tubules that consisted of sertoli cells with only spermatogonia; spermatogonia + spermatocyte; spermatogonia + spermatocyte + spermatid was obtained.
