Zuclomifene (INN; or zuclomiphene (USAN)) is a nonsteroidal selective estrogen receptor modulator (SERM) of the triphenylethylene group that was never marketed.[1][2][3][4] It is one of the two stereoisomers of clomifene, which itself is a mixture of 38% zuclomifene and 62% enclomifene.[4] Zuclomifene is the (Z)-stereoisomer of clomifene, while enclomifene is the (E)-stereoisomer.[1][2] Whereas zuclomifene is described as mildly estrogenic, enclomifene is described as antiestrogenic.[4][5] In accordance, unlike enclomifene, zuclomifene is antigonadotropic due to activation of the estrogen receptor and reduces testosterone levels in men.[4] It is also about five times more potent than enclomifene in inducing ovulation.[5]
