Spermiogenesis is the process by which spermatids, which are haploid cells resulting from the second meiotic division of secondary spermatocytes, undergo extensive structural changes to become mature spermatozoa (sperms). During spermiogenesis, the spermatids develop a streamlined shape with a head, midpiece, and tail, acquire motility through the formation of flagella, and develop specialized organelles like the acrosome.

Spermiation refers to the final step of spermatogenesis where mature spermatozoa are released from Sertoli cells into the lumen of the seminiferous tubules. It involves the detachment of spermatozoa from Sertoli cells and their passage into the epididymis for further maturation and storage before ejaculation.
