In 2023, anti\u2010M\u00fcllerian hormone (AMH) was incorporated into defining PCOM. Although PCOS\u2010related symptoms often improve with age, some women continue to exhibit symptoms and meet the PCOS diagnostic criteria even as they age. This study examined AMH patterns across age groups in women who already met the PCOS diagnostic criteria according to either the Rotterdam or the stricter 2018 criteria.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This cross\u2010sectional study included 725 women diagnosed with PCOS according to the Rotterdam criteria, of whom 520 also fulfilled the 2018 criteria.
