In human (and other mammalian) females, oögenesis begins during fetal development and is arrested in the Metaphase I until the time of ovulation. Fertilization triggers the completion of Meiosis II in the oöcyte. Ovulation ends with menopause.

The follicle secretes estrogen before ovulation; the corpus luteum secretes both estrogen and progesterone after ovulation. Hormones from the hypothalamus and anterior pituitary control the ovarian cycle.
