Notes: Initial recruitment is gonadotropin independent and involves the differentiation of primordial follicles into primary and preantral follicles, the majority of which undergo atresia prior to puberty. Cyclic recruitment occurs after puberty and is gonadotropin dependent. Cyclic recruitment involves the growth and development of antral follicles through to mature preovulatory follicle selection and ovulation or atresia. This process continues throughout a female’s reproductive lifespan until the primordial follicle pool is depleted.
