      • Set of long, twisted tubules in the testes
      • Lined with Sertoli cells
        • Sertoli cells provide nourishment to sperm and regulate their development
      • Millions of sperm are produced every day
    • Stimulated by FSH (from anterior pituitary)
      • Also by testosterone to a lesser extent
