Estradiol undecylenate (EUe; developmental code name SH-368) is an estrogen medication and estrogen ester which was never marketed. It is the C17β undecenoate (undecylenate) ester of estradiol. Following an intramuscular injection, EUe has a very prolonged effect, exceeding that of other estradiol esters like estradiol valerate and estradiol enanthate. Due to its very long duration of action, EUe releases only subthreshold amounts of estradiol at conventional doses. However, this may still be useful in menopausal hormone therapy.

ISBN 978-3-0348-7044-3. Retarded estrogens. In animal experiments it has been shown esterification at C-17 results in longer retarding effects than esterification at C-3. The optimal retarding effect (exceeding 29 days) may be obtained with the C-17 oenanthate. However, the effect exceeds the time interval of 28 days normally considered sufficient for the treatment of a female during one period and for this reason the shorter active estradiol-17-valerianate has been introduced. The estradiol undecylenate has a more protracted effect but it releases only subthreshold doses of steroid (advantage may be taken of this for the treatment of menopause).
