Evidence-based guideline: premature ovarian insufficiency

Study question How should premature/primary ovarian insufficiency (POI) be diagnosed and managed, based on the best available evidence from published literature? Summary answer The current guideline provides 145 recommendations on symptoms, diagnosis, causation, sequelae and treatment of POI. What is known already POI presents a significant challenge to women's health, with far-reaching implications, both physically and emotionally. The potential implications include adverse effects on quality of life, on fertility and on bone, cardiovascular and cognitive health. Although hormone therapy (HT) can mitigate some of these effects, many questions still remain regarding the optimal management of POI. Study design, size, duration The guideline was developed according to the structured methodology for development of European Society of Human Reproduction and Embryology (ESHRE) guidelines. Key questions were determined by a group of experts and informed by a scoping survey of women and healthcare professionals. Literature searches and assessment were then performed. Papers published up to 30 January 2024 and written in English were included in the guideline. An integrity review was conducted for the randomized controlled trials on POI included in the guideline. Participants/materials, setting, methods Based on the collected evidence, recommendations were formulated and discussed within the guideline development group until consensus was reached. Women with lived experience of POI informed the recommendations in general, and particularly those on provision of care. A stakeholder review was organized after finalization of the draft. The final version was approved by the guideline development group and the ESHRE Executive Committee. Main results and the role of chance New data indicate a higher prevalence of POI, 3.5%, than was previously thought. This guideline aims to help healthcare professionals apply best practice care for women with POI. The recent update of the POI guideline covers 40 clinical questions on diagnosis of the condition, the different sequelae, including bone, cardiovascular, neurological and sexual function, fertility and general well-being, and treatment options, including HT. The list of clinical questions was expanded from the previous iteration of the guideline (2015) based on the scoping survey and appreciation of emerging knowledge of POI. Questions were added on the role of anti-M & uuml;llerian hormone (AMH) in the diagnosis of POI, fertility preservation, muscle health and specific considerations for HT in iatrogenic POI. Additionally, the topic on complementary treatments was extended with specific focus on non-hormonal treatments and lifestyle management options. Significant changes from the previous 2015 guideline include the recommendations that only one elevated follicle stimulating hormone (FSH) >25 IU is required for diagnosis of POI and guidance that AMH testing, repeat FSH measurement and/or AMH may be required where there is diagnostic uncertainty. Recommendations were also updated regarding genetic testing, estrogen doses and regimens, use of the combined oral contraceptive and testosterone therapy. Women with lived experience of POI informed the recommendations on provision of care. Limitations, reasons for caution The guideline describes different management options, but it must be acknowledged that for most of these options, supporting evidence is limited for POI. Wider implications of the findings The guideline provides healthcare professionals with clear advice on best practice in POI care, based on the best evidence currently available. In addition, a list of research recommendations is provided to guide further studies in POI.
