I will agree with Dr Karen.  Return of sexual behavior in males is a sign
of adrenal gland disease and likely to be adrenal carcinoma.  The Lupron
should help lower his hormone levels, but I would do surgery if possible.
It will be interesting to see which hormone(s) is elevated in your boy.
 
Hope that helps,
