Research is exploring the relationship between polycystic ovary syndrome (PCOS) and autoimmune thyroid disorders, including the prevalence of anti-thyroid peroxidase antibodies among women with PCOS. Studies are investigating potential links between PCOS and conditions such as Hashimoto's thyroiditis and autoimmune thyroiditis. The findings may shed light on the role of autoimmune factors in PCOS and their impact on related health issues, including ovarian reserve and pregnancy outcomes.
