Control of androgen secretion and activity and some sites of action of antiandrogens (1), competitive inhibition of GnRH receptors (2), stimulation (+, pulsatile administration) or inhibition via desensitization of GnRH receptors (-, continuous administration) (3), decreased synthesis of testosterone in the testis (4), decreased synthesis of dihydrotestosterone by inhibition of 5a-reductase (5), competition for binding to cytosol androgen receptors.
