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.
