Clomiphene Citrate Tablets

Anti-hormone drugs. The mechanism of ovulation stimulation by this product is not fully understood. Since this product has a weak excitatory and strong antagonistic effect on estrogen, ovulation stimulation may be in the hypothalamus. First, antagonism is dominant, and by competitively occupying the hypothalamic estrogen receptors, it interferes with the negative feedback of endogenous estrogen, promotes the secretion of luteinizing hormone and follicle-stimulating hormone, and then stimulates follicle growth. After the follicle matures, the release of estrogen increases, and the release of preovulatory gonadotropin is stimulated by positive feedback to reach a peak, thus ovulation. The treatment of male infertility may be related to the increase of FSH and LH and the promotion of sperm production.

The main ingredient is clomiphene citrate, and its chemical name is N,N-diethyl-2-[4-(1,2-diphenyl-2-chlorovinyl)phenoxy]ethylamine citrate.

This product is a white, round, flat tablet with a notch on one side.
