The Testis

  • testis is developed in much the same way as the ovary
  • earliest stages it consists of a central mass of epithelium covered by a surface epithelium
  • in the central mass a series of cords appear
  • periphery of the mass is converted into the tunica albuginea
    • excluding the surface epithelium from any part in the formation of the tissue of the testis
  • cords of the central mass run together toward the future hilus
    • form a network which ultimately becomes the rete testis
  • cords develop the seminiferous tubules
  • between them connective-tissue septa extend
  • seminiferous tubules become connected with outgrowths from the Wolffian body
    • form the efferent ducts of the testis
