How does Ethinyl Estradiol work?
Ethinyl Estradiol is a combination oral contraceptive (COC) that contains 2 hormones: drospirenone (a progestin) and Ethinyl Estradiol (an estrogen). Both hormones work together to prevent pregnancy by:
- Suppressing ovulation (release of an egg from the ovary)
- Changing cervical mucus to block sperm movement
- Creating an unfriendly environment for the fertilized egg by changing the lining in the uterus (womb)
- Ethinyl Estradiol also helps with acne by lowering the amount of testosterone in your body. This leads to less oil production and clogging of the pores of the skin, which helps prevent acne.
