* At the beginning of each cycle, a few primary follicles begin to develop into antral follicles.
* At the beginning of each cycle, a few primary follicles begin to develop into antral follicles.
* What causes the selection of particular follicles is unknown, but it is thought to be due to the paracrine action of growth factors such as EGF and IGFs.
* What causes the selection of particular follicles is unknown, but it is thought to be due to the paracrine action of growth factors such as EGF and IGFs.
* Major enlargement of the follicle is not due to the oocyte increasing in size, but down to the gain in follicular fluid secreted by the granulosa cells.
* Major enlargement of the follicle is not due to the [[The_Ovary_-_Oogenesis_-_Anatomy_%26_Physiology|oocyte]] increasing in size, but down to the gain in follicular fluid secreted by the granulosa cells.
* A further selection process occurs whereby a single follicle (the dominant follicle) is selected for continued development.
* A further selection process occurs whereby a single follicle (the dominant follicle) is selected for continued development.
* What causes this single follicle to be chosen is unknown.
