Oral Contraceptives • FSH and LH are messengers from the pituitary gland that control the female reproductive cycle. • The secretion of FSH and LH can be controlled by the amount of estrogen and progesterone present • Without FSH and LH, ovulation (release of egg from ovary) cannot occur. • This is how oral contraceptives work – pill is mixture of estrogen and progesterone that work to prevent release of FSH and LH from pituitary gland and thereby prevent ovulation. • No ovulation = no egg in uterus = no baby.
