What is Clomid?
Clomiphene Citrate (Clomid) is a SERM — mixed ERα/ERβ agonist/antagonist. Acts as ER antagonist at hypothalamus/pituitary → reduces negative estrogen feedback → increases GnRH/LH/FSH → endogenous testosterone stimulation. Racemic mixture: trans-isomer (enclomiphene, anti-estrogenic) and cis-isomer (zuclomiphene, pro-estrogenic). CAS 50-41-9.
Research Applications
HPG Axis Restoration Hypothalamic ER antagonism → GnRH/LH/FSH upregulation → testosterone Male Hypogonadism Endogenous T stimulation — PCT and fertility restoration models SERM Pharmacology ERα/ERβ mixed agonist/antagonist — tissue-selective ER research Ovulation Induction Hypothalamic-pituitary ER blockade → follicular development vs Enclomiphene Comparison Racemic vs pure trans-isomer — estrogenic isomer contribution
