We just got my son’s bone age results back (10 yr. old SWCAH) and it is advanced.  His endo is recommending he start taking Armatase Inhibitor.  I understand it blocks testosterone from converting to estrogen thus slowing down bone age advancement.  I was curious if anyone child is or has been on it and what their experience has been (good or bad).  Any advice would be greatly appreciated.
