Enclomiphene is a single isomer of clomiphene citrate and is an orally active proprietary small molecule compound. Enclomiphene is a non-steroidal estrogen receptor antagonist that promotes gonadotropin-dependent testosterone secretion by the testes. Enclomiphene is the trans-isomer of clomiphene, which is about a 60-40 mix of trans (Enclomiphene) and cis (Zuclomiphene). While enclomiphene (trans-clomiphene) is an estrogen antagonist, zuclomiphene (cis-clomiphene) is a mixed agonist, responsible for the estrogenic activity and therefore the common side effects sometimes seen in males. The enclomiphene isomer is responsible for the anti-estrogen activity and the restoration of ones hypothalamic–pituitary–gonadal axis. In recent clinical trials, enclomiphene increased serum LH and FSH with concomitant increases in testosterone in men with secondary hypogonadism. Enclomiphene showed overall better results than testosterone gels, which raise serum testosterone but can lower LH and FSH at the same time. |
