Several diagnostic approaches are available, including hysterosalpingography (HSG), hysterosalpingo-contrast sonography (HyCoSy), hysterosalpingo-foam sonography (HyFoSy), and laparoscopy with chromopertubation. This systematic review aimed to synthesize current evidence on their diagnostic performance, clinical applicability, and role in contemporary diagnostic pathways.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>PubMed\/MEDLINE, Embase, the Cochrane Library, and Web of Science were searched for studies published between January 2015 and March 2026. Studies evaluating methods for tubal patency or morphological assessment in women undergoing infertility investigation were considered. A total of 21 studies were included. Owing to clinical and methodological heterogeneity, particularly differences in study populations, diagnostic thresholds, and reference standards, the findings were synthesized qualitatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>HSG generally demonstrated high sensitivity but variable specificity, limiting its reliability for confirming tubal occlusion. HyCoSy showed potentially useful diagnostic performance as a non-invasive screening method, although estimates varied across studies. Several studies reported favorable specificity, predictive values, and agreement measures for HyFoSy, together with improved patient tolerability; however, findings were not uniform and were influenced by methodological heterogeneity and differences in reference standards. Laparoscopy with chromopertubation remained the reference standard for assessing tubal patency and identifying concomitant pelvic pathology, although its invasive nature limits its routine use.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Current evidence supports a stepwise approach to tubal assessment in which less invasive methods may be used initially, with confirmatory or invasive techniques reserved for selected cases. Such an approach may improve diagnostic confidence while reducing unnecessary procedural burden and risks. Further well-designed comparative studies using standardized reference standards and outcome definitions are needed to clarify the relative diagnostic value of available techniques.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/frph.2026.1861471","type":"journal-article","created":{"date-parts":[[2026,10,7]],"date-time":"2026-10-07T05:53:27Z","timestamp":1791352407000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Diagnostic approaches for tubal factor infertility: a systematic review of HSG, HyCoSy, HyFoSy, and laparoscopy"],"prefix":"10.3389","volume":"8","author":[{"given":"Adalyat","family":"Alenova","sequence":"first","affiliation":[{"name":"Kazakh Medical University \u201cKSPH\u201d","place":["Almaty, Kazakhstan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Almagul","family":"Kauysheva","sequence":"additional","affiliation":[{"name":"Department of Science and Human Resources, Ministry of Health of the Republic of Kazakhstan","place":["Astana, Kazakhstan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anuar","family":"Korkan","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology \u2116 1, Medical University of Astana","place":["Astana, Kazakhstan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Islam","family":"Magalov","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Baku Branch of the First Moscow State Medical University","place":["Baku, Azerbaijan"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,10,7]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.7759\/cureus.30990","article-title":"A review of tubal factors affecting fertility and its management","volume":"14","author":"Ambildhuke","year":"2022","journal-title":"Cureus"},{"key":"B2","doi-asserted-by":"publisher","first-page":"215","DOI":"10.31128\/AJGP-09-22-6576","article-title":"Pelvic inflammatory disease and infertility","volume":"52","author":"Hunt","year":"2023","journal-title":"Aust J Gen Pract"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.7759\/cureus.38881","article-title":"Tubal pathologies and fertility outcomes: a review","volume":"15","author":"El-Kharoubi","year":"2023","journal-title":"Cureus"},{"key":"B4","doi-asserted-by":"publisher","first-page":"1537506","DOI":"10.3389\/fmed.2025.1537506","article-title":"Clinical applications, advances, and future directions in hysterosalpingography","volume":"12","author":"Wang","year":"2025","journal-title":"Front Med"},{"key":"B5","doi-asserted-by":"publisher","first-page":"26884844261434409","DOI":"10.1177\/26884844261434409","article-title":"Multimodal hysterosalpingography for one-stop assessment of tubal patency and fimbrial function: a prospective diagnostic trial","volume":"7","author":"Xie","year":"2026","journal-title":"Women\u2019s Health Reports"},{"key":"B6","doi-asserted-by":"publisher","first-page":"e17461","DOI":"10.1016\/j.heliyon.2023.e17461","article-title":"Evaluation of tubal patency by hysterosalpingo-contrast sonography (HyCoSy): controversies, dilemmas and considerations","volume":"9","author":"Xu","year":"2023","journal-title":"Heliyon"},{"key":"B7","doi-asserted-by":"publisher","first-page":"104380","DOI":"10.1016\/j.rbmo.2024.104380","article-title":"Is hysterosalpingo-foam sonography the new gold standard for assessing tubal patency?
