Ovary - Antral Follicle
ovary, monkey (Stain - Haematoxylin Eosin)
- Small fluid-filled spaces become visible between the granulosa cells as the follicle reaches a diameter of about 400 µm.
- These spaces enlarge and fuse to form the follicular antrum, which is the defining feature of the secondary follicle.
- The oocyte is now located eccentric in the follicle in the cumulus oophorus, where it is surrounded by granulosa cells.
- The theca folliculi differentiates with the continued growth of the follicle into a theca interna and a theca externa.
- Vascularization of the theca interna improves, and the spindle-shaped or polyhedral cells in this layer start to produce oestrogens.
- The theca externa retains the characteristics of a highly cellular connective tissue with smooth muscle cells.
- The oocyte of the secondary follicle reaches a diameter of about 125 µm.
- The follicle itself reaches a diameter of about 10-15 mm.
