Estradiol 3-tetrahydropyranyl ether is a synthetic estrogen and estrogen ether which was never marketed.^{[1][3][4][2][5][6][7]} It has been reported to possess improved oral activity relative to estradiol.^[1][3][4] One study in animals found that it had 15 times the oral activity of estradiol.^[1][3]
