Abstract
Thyroid hormones are important for normal reproductive function, and maternal thyroid
dysfunction has been associated with infertility, miscarriage, preterm birth, and
poor neurodevelopment in the offspring. Thyroid autoimmunity is the leading cause
of thyroid dysfunction in women of reproductive age. Women with thyroid autoimmunity,
even with normal thyroid function, appear to be at a higher risk for poor reproductive
outcomes, including miscarriage and preterm birth. Thyroxine replacement in women
with thyroid autoimmunity with or without appreciable thyroid dysfunction may improve
pregnancy outcomes. Thus, identification and treatment of women with thyroid autoimmunity
may optimize reproductive success.
