二硬脂酸雌二醇（英语：Estradiol distearate，缩写EDS，或称为双十八烷酸雌二醇酯，estradiol dioctadecanoate）是一种雌激素酯（英语：estrogen ester），可作为在体内长期作用的雌二醇前体药物，但从未上市。
Note: Though not listed here, many anabolic steroids can also be estrogenic as they can be aromatized into estrogen-like metabolites that possess estrogenic activity.
Note: Xenoestrogens (e.g., phytoestrogens and mycoestrogens) are not included here. For a full list of xenoestrogens, see here.
Note: 5α-reductase and 21-hydroxylase inhibitors may also affect estrogen levels as they prevent metabolism of estrogen steroid precursors.
