BCPs contain a combination of estrogen and progestin. All BCPs now have one main source of estrogen — ethinyl estradiol. Ethinyl estradiol is a constant in the BCP equation but the part that changes is the progestin level. There are a number of different types of progestin and some of them are higher in androgenic value than others. I’ve compiled data from a number of different sources and come up with a handy chart that helps you identify which BCPs are high in androgens and which ones are lower. Remember that the higher the androgens, the more likely it will cause excessive hair loss, acne and hirsutism.
