Spermatocyte is a male gametocyte, which is derived from a spermatogonium and then undergoes meiosis to give 4 haploid spermatids. Initially in spermatogenesis, a spermatogonium divides by mitosis into two 'primary spermatocytes'. A primary spermatocyte is diploid. It then undergoes meiosis to form two 'secondary spermatocytes', which are haploid.

Spermatid is any of the four haploid cells formed by meiosis in a male organism that develop into spermatozoa without further division.
