The primary dataset comprised 21 women around 50\u2009years of age (mean\u2009\u00b1\u2009SD, 50.3\u2009\u00b1\u20091.3\u2009years), with seven participants in each group. Landmarks on the pelvis and urogenital hiatus were collected on magnetic resonance imaging scans. Pelvic shape was analyzed using geometric morphometry and principal component analysis. The findings were validated in a small secondary dataset of four parous women in their 30s, of whom two had POP and two were controls.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Significant differences were observed between cases, controls and nulliparae in the primary dataset when soft tissue shape and pelvic shape were analyzed together on principal component analysis.

This difference was generalizable to younger women in the secondary dataset.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>\n                      The shape of the pelvis in adult women affects their risk for postpartum POP. \u00a9 2025 The Author(s).\n                      <jats:italic>Ultrasound in Obstetrics &amp; Gynecology<\/jats:italic>\n                      published by John Wiley &amp; Sons Ltd on behalf of International Society of Ultrasound in Obstetrics and Gynecology.\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/uog.70101","type":"journal-article","created":{"date-parts":[[2025,10,10]],"date-time":"2025-10-10T01:10:16Z","timestamp":1760058616000},"page":"659-666","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Pelvic shape predisposes for pelvic organ prolapse: a geometric morphometry study"],"prefix":"10.1002","volume":"66","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8548-0995","authenticated-orcid":false,"given":"E.","family":"Stansfield","sequence":"first","affiliation":[{"name":"Evolutionary Biology University of Vienna  Vienna Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Phan","sequence":"additional","affiliation":[{"name":"Department of Transfusion Medicine and Cell Therapy Medical University of Vienna  Vienna Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4492-8906","authenticated-orcid":false,"given":"B.","family":"Fischer","sequence":"additional","affiliation":[{"name":"Evolutionary Biology University of Vienna  Vienna Austria"},{"name":"Konrad Lorenz Institute for Evolution and Cognition Research  Klosterneuburg Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1012-7713","authenticated-orcid":false,"given":"J.
