Rather than being solely an ovarian disorder, PMOS is now recognized as a complex systemic disease involving endocrine, metabolic, reproductive and inflammatory pathways.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Importantly, this change does <strong>not<\/strong> modify the diagnostic criteria or current treatment recommendations. Instead, it aims to improve awareness, facilitate earlier diagnosis, and better reflect the multisystem nature of the disorder.<\/p>\n\n\n\n<h2 id=\"h-why-has-the-name-changed\" class=\"wp-block-heading\">Why has the name changed?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For decades, the term <em>polycystic ovary syndrome<\/em> has been considered misleading.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The condition is not caused by ovarian cysts. Instead, ultrasound typically reveals multiple small follicles whose development has been arrested. Referring to these follicles as &#8220;cysts&#8221; has contributed to misunderstanding among both patients and healthcare professionals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The previous name also underestimated the condition&#8217;s metabolic and endocrine components, often suggesting it was solely a gynecological disorder.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The new name\u2014<strong>Polyendocrine Metabolic Ovarian Syndrome<\/strong>\u2014highlights its complex hormonal and metabolic origins while recognizing its effects throughout the body.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The condition affects an estimated <strong>170 million women worldwide<\/strong>, with approximately <strong>one in eight women<\/strong> living with the syndrome. However, around <strong>70% remain undiagnosed<\/strong>.<\/p>\n\n\n\n<h2 id=\"h-do-the-diagnostic-criteria-change\" class=\"wp-block-heading\">Do the diagnostic criteria change?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">No. The international consensus confirms that the current diagnostic criteria remain unchanged.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Women aged 20 years and older must meet at least two of the following criteria:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Oligo-ovulation or irregular ovulation<\/li>\n\n\n\n<li>Clinical or biochemical hyperandrogenism<\/li>\n\n\n\n<li>Polycystic ovarian morphology on ultrasound or elevated Anti-M\u00fcllerian Hormone (AMH)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For adolescents aged 10\u201319 years, diagnosis requires both ovulatory dysfunction and hyperandrogenism.<\/p>\n\n\n\n<h2 id=\"h-why-is-pmos-considered-a-systemic-disease\" class=\"wp-block-heading\">Why is PMOS considered a systemic disease?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The new terminology reflects the multiple biological mechanisms involved in the condition.<\/p>\n\n\n\n<h3 id=\"h-neuroendocrine-dysfunction\" class=\"wp-block-heading\">Neuroendocrine dysfunction<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Alterations in GnRH and LH secretion, changes in the LH\/FSH ratio, and abnormalities involving dopamine, serotonin and GABA contribute to hormonal dysregulation.<\/p>\n\n\n\n<h3 id=\"h-insulin-resistance\" class=\"wp-block-heading\">Insulin resistance<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Approximately 85% of women with PMOS present some degree of insulin resistance. Elevated insulin levels stimulate ovarian androgen production, contributing to hormonal imbalance.<\/p>\n\n\n\n<h3 id=\"h-ovarian-hyperandrogenism\" class=\"wp-block-heading\">Ovarian hyperandrogenism<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Insulin resistance promotes increased androgen production by ovarian theca cells while reducing hepatic production of Sex Hormone-Binding Globulin (SHBG), leading to higher circulating androgen levels.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This hormonal imbalance contributes to visceral fat accumulation, chronic inflammation and worsening insulin resistance, creating a self-perpetuating cycle.<\/p>\n\n\n\n<h3 id=\"h-follicular-dysfunction\" class=\"wp-block-heading\">Follicular dysfunction<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Excess androgen levels interfere with normal follicular development, leading to arrested follicles, elevated AMH levels and, in some cases, reduced oocyte quality.<\/p>\n\n\n\n<h2 id=\"h-health-consequences-beyond-fertility\" class=\"wp-block-heading\">Health consequences beyond fertility<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">PMOS is associated with several long-term health risks, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Central obesity<\/li>\n\n\n\n<li>Insulin resistance<\/li>\n\n\n\n<li>Prediabetes and type 2 diabetes<\/li>\n\n\n\n<li>Non-alcoholic fatty liver disease<\/li>\n\n\n\n<li>Dyslipidemia<\/li>\n\n\n\n<li>Hypertension<\/li>\n\n\n\n<li>Cardiovascular disease<\/li>\n\n\n\n<li>Obstructive sleep apnea<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Other commonly affected systems include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Reproductive:<\/strong> irregular menstrual cycles, infertility, pregnancy complications and increased risk of endometrial cancer.<\/li>\n\n\n\n<li><strong>Dermatological:<\/strong> acne, hirsutism and androgenic alopecia.<\/li>\n\n\n\n<li><strong>Psychological:<\/strong> anxiety, depression, eating disorders and reduced quality of life.<\/li>\n\n\n\n<li><strong>Inflammatory:<\/strong> chronic low-grade inflammation and oxidative stress.<\/li>\n\n\n\n<li><strong>Gut-endocrine axis:<\/strong> intestinal dysbiosis and altered incretin function.<\/li>\n\n\n\n<li><strong>Autonomic nervous system:<\/strong> increased sympathetic activity, chronic stress and sleep disturbances.<\/li>\n<\/ul>\n\n\n\n<h2 id=\"h-what-does-this-mean-for-fertility\" class=\"wp-block-heading\">What does this mean for fertility?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">PMOS remains one of the leading causes of ovulatory infertility.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Irregular or absent ovulation may reduce the chances of natural conception. Additionally, insulin resistance, hyperandrogenism and chronic inflammation can negatively affect ovarian function, oocyte quality and the hormonal environment necessary for pregnancy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For women trying to conceive, individualized assessment is essential. A comprehensive fertility evaluation should include hormonal, metabolic and reproductive factors to develop the most appropriate treatment strategy.<\/p>\n\n\n\n<h2 id=\"h-a-more-accurate-understanding-of-the-condition\" class=\"wp-block-heading\">A more accurate understanding of the condition<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The adoption of the name <strong>Polyendocrine Metabolic Ovarian Syndrome<\/strong> represents a significant step forward in understanding this complex disorder.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Rather than focusing exclusively on the ovaries, the new terminology acknowledges PMOS as a chronic systemic condition requiring a multidisciplinary and personalized approach.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Improved awareness and earlier diagnosis may ultimately lead to better long-term health outcomes and more effective fertility care for affected women.<\/p>\n\n\n\n<h3 id=\"h-references\" class=\"wp-block-heading\">References<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Teede HJ, et al. <em>Polyendocrine Metabolic Ovarian Syndrome, the new name for Polycystic Ovary Syndrome: a multistep global consensus process.<\/em> The Lancet. 2026.<\/li>\n\n\n\n<li>International Evidence-Based Guideline for the Assessment and Management of Polycystic Ovary Syndrome. 2023.<\/li>\n\n\n\n<li>Society for Endocrinology. <em>Polyendocrine Metabolic Ovarian Syndrome (PMOS) is the new name for PCOS.<\/em> 2026.<\/li>\n<\/ul>\n\n\n\n<h3 id=\"h-faqs\" class=\"wp-block-heading\">FAQs<\/h3>\n\n\n\n<details class=\"faq-item\">\n<summary>Does the new name change the diagnosis or treatment?<\/summary>\n<p>No. The diagnostic criteria and treatment recommendations remain unchanged.
