Spermatocytes

Spermatocytes are developing male germ cells that undergo meiosis. Primary spermatocytes (diploid, 4N DNA) result from spermatogonial mitosis. They undergo Meiosis I to form two secondary spermatocytes (haploid, 2N DNA). Secondary spermatocytes rapidly undergo Meiosis II to produce four spermatids (haploid, 1N DNA). This process occurs within the seminiferous tubules, supported by Sertoli cells.
