spermatocyte

 [sper-mat´o-sīt]

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.

secondary spermatocyte
a cell produced by meiotic division of the primary spermatocyte, and which gives rise to the spermatid.
