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.
