    Product Description

    Clomiphene is a selective estrogen receptor modulator that impairs the activation of estrogen receptors (ERs) by 17β-estradiol.1,2 It potently binds both ERα and ERβ (Ki = 0.9 and 1.2 nM, respectively).3 Clomiphene enhances the release of gonadotropin-releasing hormone, stimulating the release of follicle-stimulating hormone and luteinizing hormone, culminating in ovulation.1,4

    WARNING This product is not for human or veterinary use.
