Ovarian follicles. Light micrograph of a section through a foetal ovary showing primordial follicles (light pink ovals). Each primordial follicle contains an oocyte (spotty,circular)with a single layer of flattened granulosa cells around it. These follicles will not mature any further until sexual maturity is reached. Then,during each menstrual cycle several primordial follicles will mature into secondary follicles. One secondary follicle will go on to become a Graafian follicle,releasing its oocyte at ovulation | |
