Inositols, a group of naturally occurring sugar alcohols, have gained attention for their potential benefits during pregnancy. This abstract provides a comprehensive review of the current literature on using inositols, primarily myo-inositol (MI) and D-chiro-inositol (DCI) in pregnancy. Inositols are crucial in cellular signal transduction and insulin sensitivity, making them integral to various physiological processes. Several studies suggest that inositols may contribute to preventing and managing gestational diabetes mellitus (GDM). MI, in particular, has shown promise in improving insulin sensitivity and mitigating insulin resistance, thereby influencing glucose metabolism. As our understanding of inositol's role in pregnancy deepens, it may emerge as a valuable supplement to enhance maternal and fetal health outcomes.</p>","PeriodicalId":12865,"journal":{"name":"Gynecological Endocrinology","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142371663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Human endometrial stromal cells (hESCs) were collected for primary culture and treated with relevant receptor antagonists and activators.
