Spermatozoa are generated and mature within a germline syncytium. Differentiation of haploid syncytial spermatids into single motile sperm requires the encapsulation of each spermatid by an independent plasma membrane and the elimination of most sperm cytoplasm. a process known as individualization. Apoptosis is mediated by caspase family proteases. https://mabelandfoxs.shop/product-category/kids-watch/
