Spermatogenesis

  • walls of Seminiferous tubules => spermatogonia goes through multiplication phase => diploid cells => divide by mitosis to form more diploid cells
  • some of these cells grow to new spermatogonia but others grow much larger which are called primary spermatocytes
  • Primary spermatocytes then undergo meiosis forming two haploid cells called secondary spermatocytes
  • Secondary spermatocytes then go through second division, each forming spermatids => also haploids
  • then entry maturation stage which mature into spermatozoa
  • Sertoli cells nurture the cells that are developing into sperms and also interact with hormones produced…
