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.

sec·on·dar·y sper·ma·to·cyte

the spermatocyte derived from a primary spermatocyte by the first meiotic division; each secondary spermatocyte produces two spermatids by the second meiotic division.

sec·on·dar·y sper·mat·o·cyte

(sek'ŏn-dar-ē spĕr-mat'ō-sīt)
The spermatocyte derived from a primary spermatocyte by the first meiotic division; each secondary spermatocyte produces two spermatids by the second meiotic division.

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.

In the secondary spermatocyte, the thick chromatids are clumped along the cell periphery.
Increase in percentage of abnormal seminiferous tubules along with the decline in number of spermatogonia, primary spermatocytes, secondary spermatocytes and spermatids probably correspond to the decrease in testosterone production or inhibition of pituitary gonadotropin secretion, which resulted in disruption of spermatogenesis (Raji and Bolarinwa, 1997).
Secondary spermatocytes are found less often than their predecessors.
In addition, the observation of meiotic anaphases I and II in cysts of primary and secondary spermatocytes, respectively, showed that M.
Only two stages were present: (1) recrudescence in which there is a renewal of germinal epithelium for the next period of sperm formation; seminiferous tubules contain primary, secondary spermatocytes and varying amounts of spermatids and (2) spermiogenesis in which clusters of spermatozoa line the lumina of the seminiferous tubules and several rows of metamorphosing spermatids are present.
Secondary spermatocytes and occasional spermatids were present in some males undergoing recrudescence.
In recrudescence (recovery) there was renewal of spermatogenic cells characterized by spermatogonial divisions; primary and secondary spermatocytes were typically present.
There was a proliferation of germ cells; primary and secondary spermatocytes and occasional spermatids were present in testes undergoing recrudescence.
