Mechanism Of Action and Pharmacodynamic Effects Click here for help
Although te precise mechanism is not well defined (direct activation of the hypothalamic-pituitary axis, or altered estrogen-induced feed-back inhibition), the outcome of treatment with clomiphene is drug-induced release of the gonadotropins FSH and LH, resulting in the development and maturation of an ovarian follicle and subsequent ovulation.
