Human Ovary Follicles - light and electron microscopy

Follicles from normal human ovaries.

  • A to D - Light micrographs
  • E to G - Electron micrographs
Light micrographs Electron micrograph
  • A - primordial follicle
  • B - primary follicle
  • C - 4 mm follicle
  • D - 5 mm atretic follicle
  • E - follicle wall of primordial follicle
  • F and G -follicle wall of pre-antral follicles

Arrows indicate the position of the follicular basal lamina. G, membrana granulosa; T, theca interna; O, oocyte. Scale bar = 5 µm.
