Prevention of ovulation occurs via inhibition of the hypothalamic–pituitary–gonadal axis, through progesterone and estrogen providing negative feedback to the hypothalamus and inhibiting the production of gonadotropin releasing hormone (GnRH). GnRH typically promotes the release of LH and FSH from the pituitary.
