Help a brother out.
can some one explain the difference between Aromatase inhibitors (AI) and Selective estrogen receptor modulators (SERM)?

AI's prevent the conversion of androgen's to estrogen's.
SERM's aid in blocking the absorption of estrogen's, by binding to estrogen receptors.
Correct me, if I am wrong.
