Binding Globulin

High Sex Hormone Binding Globulin: Overview

SHBG typically circulates at higher concentrations in women than in men, due to the higher ratio of estrogens to androgens in women.  For the same reason, SHBG levels in late pregnancy or after estrogen administration may be especially elevated. Elevated SHBG may be encountered in hyperthyroidism and hepatic cirrhosis.  High levels are also found in a variety of other conditions, such pregnancy.
