Ethinylandrostenediol (developmental code name SKF-2856), also known as 17α-ethynyl-5-androstenediol, is a synthetic estrogen, progestogen, and androgen which was never marketed.^[1]^[2]^[3]^[4]^[5]^[6] It is the C17α ethynyl derivative of the androgen precursor and prohormone 5-androstenediol.^[1]

Ethinylandrostenediol was first synthesized in the late 1930s and along with its close analogue ethisterone (17α-ethynyltestosterone) was one of the first progestins (synthetic progestogens) to be developed.^[7]^[8]^[9] Ethinylandrostenediol is orally active similarly to ethisterone and shows about half its progestogenic potency.^[9] Ethinylandrostenediol was an intermediate in the initial synthesis of ethisterone.^[10]

Ethinylandrostenediol shows tissue selectivity in its estrogenic effects in animals and doesn't seem to have estrogenic effects in the uterus.^[1] The androgenic activity of ethinylandrostenediol is weak.^[9]

An ester of ethinylandrostenediol, ethandrostate (17α-ethynyl-5-androstenediol 3β-cyclohexylpropionate), has been studied clinically in men and women with prostate cancer and breast cancer, respectively.^[11]^[12]^[13]^[14]^[15]

Notable structural analogues of ethinylandrostenediol include 5-androstenediol, 17α-ethynyl-3β-androstanediol, 17α-ethynyl-3α-androstanediol, ethisterone (17α-ethynyltestosterone), and methandriol (17α-methyl-5-androstenediol), as well as ethinylestradiol (17α-ethynylestradiol or 17α-ethynylestra-1,3,5(10)-triene-3,17β-diol).
