Estradiol valerate, sold under the brand names Delestrogen, Progynon Depot, and Progynova among others, is an estrogen medication which is used in hormone therapy for menopausal symptoms and low estrogen levels in women, in hormone therapy for transgender women, and in hormonal birth control for women.[4][3][9][10] It is also used in the treatment of prostate cancer in men.[9] The medication is taken by mouth or by injection into muscle once every 1 to 4 weeks.[9][10] Side effects of estradiol valerate include breast tenderness, breast enlargement, nausea, headache, and fluid retention.[11][9][10] Estradiol valerate is a synthetic estrogen and hence is an agonist of the estrogen receptor (ER), the biological target of estrogens like estradiol.[4][3][12] It is an estrogen ester and a prodrug of estradiol in the body.[12][4][3] Because of this, it is considered to be a natural and bioidentical form of estrogen.[12][3][13]

Estradiol valerate was first described in 1940 and was introduced for medical use in 1954.[14][15][16] Along with estradiol cypionate, it is one of the most widely used esters of estradiol.[17] Estradiol valerate is used in the United States, Canada, Europe, and throughout much of the rest of the world.[18][19] It is available as a generic medication.[20]

Natural estrogens considered here include: [...] Esters of 17β-estradiol, such as estradiol valerate, estradiol benzoate and estradiol cypionate. Esterification aims at either better absorption after oral administration or a sustained release from the depot after intramuscular administration. During absorption, the esters are cleaved by endogenous esterases and the pharmacologically active 17β-estradiol is released; therefore, the esters are considered as natural estrogens.
