PHARMACHOLOGIC EFFECT
Stimulator of gonadotropin production. Means with anti-estrogenic and estrogenic activity. Has a non-steroidal structure that is close to chlorotriazine. It is believed that the action of clomiphene is due to specific binding to the estrogen receptors of the hypothalamus and pituitary gland, which increases the secretion of gonadotropic hormones in the pituitary gland. This, in turn, stimulates the maturation and endocrine activity of the follicle in the ovary, as well as the subsequent formation and stimulation of the function of the yellow body. In high doses inhibits the secretion of gonadotropins. Does not possess gestagenic and androgenic activity.
