Combination hormonal contraceptive: ethinyl estradiol suppresses gonadotropin release, inhibiting ovulation; norethindrone induces endometrial changes, increasing cervical mucus viscosity.
Combination estrogen-progestin contraceptive; suppresses gonadotropins (FSH, LH) from pituitary via negative feedback, inhibiting ovulation; increases cervical mucus viscosity, impeding sperm penetration; induces endometrial thinning.
