WebSpermatids are the haploid cells that result, and they remain connected to the testis lumen’s border via cytoplasmic bridges. During spermiogenesis, spermatids are spherical, non-flagellated cells that mature and differentiate into sperms. Human spermatic development takes roughly 70 days to complete. WebOur study illuminates the molecular evolution of spermatogenesis and associated selective forces, and provides a resource for investigating the biology of the testis across mammals.
