Ovarian follicle maturation. Computer artwork showing the beginning of the follicular phase of ovarian follicle maturation. At bottom left is the primary follicle stage. The primary oocyte (egg) is green,its nucleus is grey. The follicular epithelium around the oocyte thickens to form cuboidal granulosa cells (red and yellow). The zona pellucida,a membrane that binds sperm during fertilisation,forms between these cells and the oocyte. Top centre and bottom right show the growing follicle stage,where the granulosa cells increase in number and form a capsule around the oocyte | |
