Aromatase Inhibitor Growth Study: Letrozole vs. Anastrozole

The purpose of the study is to determine if there are differences in the final height or hormone profile of short pubertal boys placed on different forms of aromatase inhibitor now routinely used to increase stature: Anastrozole and Letrozole. It also should determine if there are differences in the side effect profiles of the two drugs to be used.
