Spermatogenesis

• What is spermatogenesis?

  Process of sperm formation in testes

  
• What happens to primary spermatocytes during meiosis?

  They become secondary spermatocytes
• What are the steps of spermatogenesis?

  1. Germinal epithelium cells divide by mitosis
  2. Form diploid spermatogonia
  3. Spermatogonia enlarge to primary spermatocytes
  4. Primary spermatocytes undergo meiosis I to form secondary spermatocytes
  5. Secondary spermatocytes undergo meiosis II to form spermatids
  6. Spermatids mature into spermatozoa
