Can hyperactive thyroid increase your testosterone lvl? And if so will thyroid medication help bring it down?

In brief: See answer

Testosterone (T) exists in blood in three forms: 50-60% tightly bound to Sex Hormone Binding Globulin (SHBG) protein (biologically inactive); 40-50% weakly bound to Albumin protein (active); and 3-5% unbound/Free T (active).
Hyperthyroidism can cause higher levels of SHBG (inactive T) leading to higher serum levels of Total T, but unchanged or relative decrease in the two active forms of T.
