The final part of the formation of a mature sperm cell, in which the round, early spermatid (already with a haploid number of chromosomes) loses its round shape to acquire the features of the mature, elongated spermatozoon. Contrast with spermatogenesis, which encompasses spermiogenesis as it's completed.
The process of differentiation by which haploid spermatids are transformed into mature spermatozoa.
The process of spermatid differentiation that leads to the formation of physically mature spermatozoa.
Spermiogenesis is the final stage of spermatogenesis which sees the maturation of spermatids into mature, motile spermatozoa.
