Fig. 5. A further stage in the atresia of the ovarian follicle is seen here under Mallory's 

 connective tissue stain from a monkey on day 17. The egg is amorphous and degenerate. 

 The cavity of the follicle is collapsing and is bounded by a wavy line representing the 

 inner margin of the thick theca interna layer. This layer is losing its appearance of a 



secretory tissue.
