The most common findings in the two groups of infertility who had done laparoscopy were endometriosis (21.8%, P=0.201) followed by tubal pathology (13.5%, P=0.952). Also, the most common intrauterine pathology found in both groups were uterine septum (7.2%, P=0.753) and endometritis (6.2%, P=0.241).</p><p><strong>Conclusion: </strong>Based on the findings of this study, laparoscopy is recommended in UI after three failed IUI and ovarian stimulation, a history of pelvic pain, pelvic surgery, or pelvic infection; however, it seems that further investigation is required to recommend universal hysteroscopy to all women with UI. Nonetheless, it is still emphasized that regional practice in one's local settings may also be effective concerning the prevalence of these pathologies.</p>","PeriodicalId":14080,"journal":{"name":"International Journal of Fertility & Sterility","volume":"18 4","pages":"339-343"},"PeriodicalIF":2.3,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11589982/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142675793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
