Spermiogenesis is the final stage of spermatogenesis in which haploid round spermatids mature into spermatozoa (sperm cells). During spermiogenesis, the spermatids undergo extensive structural and morphological changes, including the formation of a head, neck, midpiece, and tail, as well as the development of organelles and structures necessary for motility. This process also involves the loss of excess cytoplasm and reshaping of the cell to form a streamlined, mature sperm cell capable of fertilizing an egg.
