This study aims to comprehensively explore the relationship between Hashimoto’s thyroiditis and female fertility by assessing ovarian reserve through anti-Müllerian hormone (AMH) levels, investigating the association between thyroid-stimulating hormone (TSH) and key reproductive parameters, and comparing pregnancy outcomes including previous in vitro fertilization (IVF) history between women with and without thyroid autoimmunity. Here, AMH is linked to autoimmune thyroid disease.
