Two types of synthetic estrogen mixtures exist that are primarily used for menopausal hormone therapy: synthetic conjugated estrogens and esterified estrogens. The synthetic conjugated estrogen mixtures are derived from yam or soy plants and contain several types of estrogen. Both synthetic conjugated estrogen products available in the United States (Cenestin with 9 estrogens and Enjuvia with 10 estrogens) contain the primary estrogens in CEE, but the products are not considered equivalent to Premarin.
