High prevalence of Hashimoto’s thyroiditis in patients with polycystic ovary syndrome: does the imbalance between estradiol and progesterone play a role?

Abstract

This study demonstrated a higher prevalence of HT, elevated TSH, anti-TPO, and anti-Tg levels in PCOS patients. Increased estrogen and estrogen/progesterone ratio seem to be directly involved in high anti-TPO levels in PCOS patients.
