Yaz and Yasmin contain slightly different amounts of two female hormones: ethinyl estradiol (an estrogen) and drospirenone (a progestin). These hormones reduce your risk of pregnancy by stopping ovulation (the release of an egg from one of your ovaries) and causing other changes in your cervix and uterus that make it harder for pregnancy to occur.
