spermatogenesis

• where are sperm made

  seminiferous tubules of the testes
• where in the seminiferous tubes does spermatogenesis take place

  germinal epithelium
• what are sperm made from

  germinal epithelial cells
• how much sperm is produced daily

  120 million
• what two hormones are needed for sperm development

  FSH and testosterone
• what does spermatogenesis start off with

  germinal epithelial cells
• what is the first step of spermatogenesis

  diploid spermatogonia divide by mitosis to produce many primary spermatocytes
• what happens to the primary spermatocytes produced from diploid spermatogonia

  they undergo meiosis to form haploid secondary spermatocytes
• what happens to the haploid secondary spermatocytes in spermatogenesis

  they will undergo meiosis 2 to form spermatids
• what will the spermatids form in spermatogenesis

  spermatozoa
• what is spermatozoa


  a mature sperm cell
• how are spermatids converted into spermatozoa

  they will differentiate and mature
• list the order of spermatogenesis

  germinal epithelium, spermatogonium, primary spermatocyte, secondary spermatocyte, spermatids, sperm(spermatozoa)
• by what process is diploid spermatogonia divided into primary spermatocytes

  mitosis
• by what process do primary spermatocytes divide into haploid secondary spermatocytes

  meiosis
• by what process do secondary spermatocytes divide into spermatids

  meiosis 2
