Zuclomifene
chemical compound
Zuclomifene (INN; or zuclomiphene (USAN)) is a nonsteroidal selective estrogen receptor modulator (SERM) of the triphenylethylene group that was never marketed. It is one of the two stereoisomers of clomifene, which itself is a mixture of 38% zuclomifene and 62% enclomifene. Zuclomifene is the (Z)-stereoisomer of clomifene, while enclomifene is the (E)-stereoisomer. Whereas zuclomifene is described as mildly estrogenic, enclomifene is described as antiestrogenic. In accordance, unlike enclomifene, zuclomifene is antigonadotropic due to activation of the estrogen receptor and reduces testosterone levels in men. It is also about five times more potent than enclomifene in inducing ovulation.
The public source identifies “Zuclomifene” as chemical compound. This brief keeps that definition visible, then builds a research path around Zuclomifene, chemical and compound.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Zuclomifene”, the useful work is to connect “chemical compound” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jan 1, 2026. The linked authority identifier is Q27257344. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
