Hence, we compared the results of doing intra-uterine insemination 36 and 42 hours after human chorionic gonadotropin (hCG) hormone injection to achieve clinical and chemical pregnancy rates.\r\nMaterials and methods: One hundred and sixty infertile women with unexplained infertility participated in this clinical trial. They were divided into two groups: those who underwent IUI 36 hours after hCG injection (control group), and those who underwent IUI 42 hours after hCG injection (case group). Statistical analyses were done using IBM-SPSS 25.0. and Chi-square test were used for data analysis.\r\nResults: The percentages of clinical and chemical pregnancies were significantly higher in the 42h group compared to the other group (P = 0.038 vs. P = 0.009, respectively). There was no significant difference regarding frequency of abortion, twin and ectopic pregnancies between the two groups (P &gt; 0.05).\r\nConclusion: Doing IUI 42 hours after hCG injection can significantly increase chances of fertility compared to doing it 36 hours after hCG injection.<\/jats:p>","DOI":"10.18502\/jfrh.v14i3.4670","type":"journal-article","created":{"date-parts":[[2020,11,18]],"date-time":"2020-11-18T05:25:48Z","timestamp":1605677148000},"source":"Crossref","is-referenced-by-count":2,"title":["Comparing the Effectiveness of Doing Intra-uterine Insemination 36 and 42 Hours after Human Chorionic Gonadotropin (HCG) Injection on Pregnancy Rate: A Randomized Clinical Trial"],"prefix":"10.18502","author":[{"given":"Mahboubeh","family":"Firouz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Narjes","family":"Noori","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marzieh","family":"Ghasemi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alireza","family":"Dashipour","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Narjes","family":"Keikha","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7770","published-online":{"date-parts":[[2020,11,18]]},"container-title":["Journal of Family and Reproductive Health"],"original-title":[],"link":[{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/JFRH\/article\/download\/4670\/4254","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/JFRH\/article\/download\/4670\/4254","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,5]],"date-time":"2026-10-05T12:07:16Z","timestamp":1791202036000},"score":1,"resource":{"primary":{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/JFRH\/article\/view\/4670"},"secondary":[{"URL":"https:\/\/jfrh.tums.ac.ir\/index.php\/jfrh\/article\/view\/1343","label":"UNIVERSITY"},{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/JFRH\/article\/view\/4670","label":"PUBLISHER"}]},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,11,18]]},"references-count":0,"URL":"https:\/\/doi.org\/10.18502\/jfrh.v14i3.4670","relation":{},"ISSN":["1735-9392","1735-8949"],"issn-type":[{"value":"1735-9392","type":"electronic"},{"value":"1735-8949","type":"print"}],"subject":[],"published":{"date-parts":[[2020,11,18]]}}}
