Estradiol undecylate (INN USAN; brand names Delestrec Depogin Primogyn Depot Progynon Depot others) is a synthetic ester specifically the 17-undecanoyl ester of the natural estrogen estradiol. It has been in use since the mid-1950s and was formerly often used to treat prostate cancer but has since largely been superseded by newer agents with fewer adverse effects for this indication.
