Delayed acth: if hypothalamus is not making, pituitary is asleep, so responds a little later (cortitrophs out of shape) Gh agonist for treatment of prostate cancer think antagonist. Desensitization of receptor, can shut off reproductive axis with an agonist. Trying to shut of gonadosteroids (prostate is target) In men, no difference (since most androgens come from testes.
