Spermatocytes are male gametocytes which can be classified into two types: primary spermatocytes and secondary spermatocytes (which undergo meiosis II  similar to mitosis but with different genetic results).
Spermatocytes are a type of male gametocyte in animals. There are two types of spermatocytes, primary and secondary spermatocytes. Each secondary spermatocyte will form two spermatids after Meiosis II.
