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.

During first meiotic division, the X and Y, in spite of the kinds of pairing involving XR and Y, remain together until early anaphase, at which time they segregate and move to opposite poles, giving rise to two kinds of secondary spermatocytes with neo-X or neo-Y, but with the same chromosome number.
