Testosterone, dihydrotestosterone and estrogens circulate in serum bound to Sex Hormone Binding Globulin (SHBG). SHBG concentrations are increased in pregnancy, hyperthyroidism, cirrhosis, oral estrogen administration and by certain drugs. Concentrations are decreased by testosterone, hypothyroidism, Cushings syndrome, acromegaly and obesity.
