Anordrin (former developmental code name AF-53), also known as 2α,17α-diethynyl-A-nor-5α-androstane-2β,17β-diol dipropionate, is a synthetic, steroidal estrogen that is used in China as a postcoital contraceptive.[2][3][4][5][6][7] It is marketed in a combination formulation with mifepristone under the brand name Zi Yun.[8][9][10] Anordrin is a selective estrogen receptor modulator, with both weak estrogenic and antiestrogenic properties.[2][11][12][13] It binds to the estrogen receptor but does not bind to the androgen receptor or the progesterone receptor.[12][14] In animals, anordrin has antigonadotropic effects, and in male animals, inhibits spermatogenesis and causes atrophy of the epididymis, prostate, and seminal vesicles.[2] It produces a dihydroxylated active metabolite, anordriol, with similar but more potent estrogenic actions.[2][15]
