List of terms related to Spermatocyte

A spermatocyte is a male gametocyte which is derived from a spermatogonium. Initially in spermatogenesis, a spermatogonium divides by mitosis into two so-called primary spermatocytes. A primary spermatocyte is also diploid, and, in turn, gives place by meiosis to two secondary spermatocytes, which this time are haploid.
