spermatider
Spermatider are haploid male germ cells formed during spermatogenesis in the testes of most animals. They arise from secondary spermatocytes after the second meiotic division, and in humans each primary spermatocyte yields four spermatids. In the seminiferous tubules, spermatids are initially round and remain connected by cytoplasmic bridges while Sertoli cells provide nourishment and structural support.
During spermiogenesis, spermatids transform into spermatozoa. The nuclear chromatin condenses and becomes highly compact; an acrosomal
Mature spermatozoa are released into the lumen of the seminiferous tubules during spermiation and subsequently travel
The process is regulated by hormones and the local testicular environment and is organized in a cyclical
