Spermatocyte
spermatocyte[spər′mad·ə‚sīt] (histology) A cell of the last or next to the last generation of male germ cells which differentiates to form spermatozoa. Spermatocyte a male sexual cell derived from a spermatogonium. Two types of spermatocytés are distinguished: primary and secondary. Primary spermatocytes develop during the growth period, and secondary spermatocytés during the second meiotic division. The latter subsequently give rise to spermatids. spermatocyte
