Does thyroid affect hCG levels?
In individual women serum hCG correlated negatively with TSH (r = 0.322; P = 0.005) and positively with free T3 (r = 0.388; P less than 0.001). These results suggest that hCG has thyrotropic activity, which, through rises in thyroid hormone levels, suppresses TSH secretion.
