Estradiol undecylenate (EUe; developmental code name SH-368)[1] is an estrogen medication and estrogen ester which was never marketed.[2] It is the C17β undecenoate (undecylenate) ester of estradiol.[2] Following an intramuscular injection, EUe has a very prolonged effect, exceeding that of other estradiol esters like estradiol valerate and estradiol enanthate.[3] Due to its very long duration of action, EUe releases only subthreshold amounts of estradiol at conventional doses.[3] However, this may still be useful in menopausal hormone therapy.[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).
