WebSpermatids are the outcome of the first meiotic division of primary spermatocytes, which produces a pair of spermatocytes to complete meiosis (second division). Spermatids are produced via the spermatogenesis process, and cells engage in spermiogenesis to create spermatozoa. Spermatids have 23 chromosomes and are haploid.

During spermatogenesis there are two cellular divisions, but only one replication of DNA so that each spermatid has 23 chromosomes (haploid), one from each pair in the original primary spermatocyte. Each successive stage in spermatogenesis is pushed ...
