Peripheral markers of thyroid hormone like SHGB
and angiotensin converting enzyme (ACE) are often elevated in TSHomas, however, they are usually normal in cases with THR (1).
binds to what few sex hormones you have remaining and reduces their bioavailability to cells in your body.

The team, led by Dr Irwin Goldstein, measured SHGB
levels in the women over a year and found they were seven times as high in pill-users as in women who had never taken them.
The fact that in our study total T, unlike free T, was found to be high but not different from controls makes us believe that high free T levels cannot be explained solely by an increase in serum SHGB
, trophoblast produced androgen binding protein, or decreased aromatase activity, but rather by an increase in its production.
A two-fold mechanism of action has been suggested: (i) interaction with blood levels of free (active) steroid hormones by displacing them from their SHBG binding sites and (ii) prevention of the interaction of prostate receptors with SHGB
But now scientists in Massachusetts, America, have found that women likely to develop pre-eclampsia have a reduced blood level of the hormone SHGB
in the first 12 weeks of pregnancy.
