This prospective observational study included 977 women of reproductive age. Each participant underwent a transvaginal ultrasound, and a 3D volume of the uterus was obtained for further analysis. Offline assessment of the uterine coronal plane was conducted to measure uterine wall thickness, fundal indentation length, and indentation angle. The diagnosis of a septate uterus was determined according to the criteria of the ESHRE-ESGE, ASRM, and CUME classifications. The prevalence of septate uterus was then calculated and compared across these classifications. The ESHRE-ESGE classification identified 132 women (13.5%) with a septate uterus. The 2016 ASRM classification identified nine women (0.9%), with an additional nine women falling into a grey zone. The 2021 ASRM classification identified fourteen women (1.4%), with eleven women in the grey zone. The CUME classification identified 23 women (2.4%). The prevalence of septate uterus was significantly higher when using the ESHRE-ESGE criteria compared to the 2016 ASRM [relative risk (RR): 7.33 (95% CI: 4.52\u201311.90)], the 2021 ASRM [RR: 5.28 (95% CI: 3.47\u20138.02)], and the CUME [RR: 5.94 (95% CI: 3.72\u20138.86)] (p &lt;\u20090.001). Our findings indicate that the ESHRE-ESGE criteria result in a significantly higher prevalence of septate uterus compared to the ASRM and CUME criteria. The ASRM 2016 criteria may underdiagnose more than half of the cases.<\/jats:p>","DOI":"10.3390\/diagnostics14182019","type":"journal-article","created":{"date-parts":[[2024,9,12]],"date-time":"2024-09-12T05:03:04Z","timestamp":1726117384000},"page":"2019","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Prevalence of Septate Uterus in a Large Population of Women of Reproductive Age: Comparison of ASRM 2016 and 2021, ESHRE\/ESGE, and CUME Diagnostic Criteria: A Prospective Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3435-8559","authenticated-orcid":false,"given":"Isabel","family":"Carriles","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, Cl\u00ednica Universidad de Navarra, 31008 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8767-3704","authenticated-orcid":false,"given":"Isabel","family":"Brotons","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Cl\u00ednica Universidad de Navarra, 31008 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3046-0940","authenticated-orcid":false,"given":"Tania","family":"Errasti","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Cl\u00ednica Universidad de Navarra, 31008 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0120-733X","authenticated-orcid":false,"given":"Alvaro","family":"Ruiz-Zambrana","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Cl\u00ednica Universidad de Navarra, 31008 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Artur","family":"Ludwin","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Medical University of Warsaw, 02-091 Warszawa, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9700-0853","authenticated-orcid":false,"given":"Juan Luis","family":"Alcazar","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Cl\u00ednica Universidad de Navarra, 31008 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e1","DOI":"10.1111\/1471-0528.15968","article-title":"Reproductive Implications and Management of Congenital Uterine Anomalies: Scientific Impact Paper No. 62 November 2019","volume":"127","author":"Akhtar","year":"2020","journal-title":"BJOG Int.
