Mechanism of action

Ethinyl estradiol is a synthetic estrogen that provides negative feedback on the hypothalamic-pituitary-ovarian axis, while norgestimate is a progestin that further suppresses LH surge and alters cervical mucus and endometrial environment. Together, these hormones prevent ovulation and create an inhospitable environment for sperm and embryo implantation.
