Thyroid hormones supplementation 50 mcg daily did not improve pregnancy outcomes in women with Hashimoto’s thyroiditis in the presence of normal thyroid function. Hashimoto’s thyroiditis was confirmed by elevated TPO antibodies at study entry. About 1,000 pregnant women were followed through full term.
This is an important study as it defies the current medical opinion of poorer pregnancy outcomes in euthyroid Hashimoto’s thyroiditis.
