Infant Ovary (human)

In this infant ovary there are a large number of primordial follicles containing immature oocytes (primordial germ cell) forming a thick cortical region and no later stages follicle development. Compare this structure with the other images of an ovary after puberty with reproductive activity.

  • inset - region of whole ovary shown in this image
  • right - ovary surface (tunica albuginea)
  • centre - ovary cortex
  • left - ovary medulla
  • primordial follicle - primary oocyte is surrounded by a single layer of follicular cells.
  • oocytes - enter diplotene stage of meiosis prophase.
    • remain arrested in this early stage of the first meiotic division as a primary oocyte (primordial follicle)
