A retrospective case\u2013control study was conducted at the Royan Institute from August 2020 to March 2022. The study included 90 couples in the COVID-19 infection phase and 31 in the vaccination phase. A total of 30 infected but unvaccinated couples were compared to a control group of 60 couples with no COVID-19 infection or vaccination history. Additionally, 31 couples underwent treatment before and after receiving the Sinopharm inactivated vaccine. Key variables analysed included sperm parameters (concentration, motility, progressive motility and morphology), ovarian parameters (antral follicle count, oocyte retrieval), embryological outcomes and pregnancy outcomes. SARS-CoV-2 infection significantly reduced sperm motility (\n                    <jats:italic>P<\/jats:italic>\n                    = 0.02) and progressive motility (\n                    <jats:italic>P<\/jats:italic>\n                    = 0.01) compared to controls. Sperm concentration and morphology showed non-significant declines. Post-vaccination analysis revealed similar but statistically insignificant changes in sperm parameters. Ovarian stimulation parameters and embryological outcomes remained unaffected by both infection and vaccination. Although biochemical, clinical pregnancy and live birth rates were lower among the infected group, these differences did not reach statistical significance (\n                    <jats:italic>p<\/jats:italic>\n                    = 0.16, 0.08 and 0.09). SARS-CoV-2 infection has been associated with impaired sperm progressive motility, which may negatively influence ICSI outcomes. In contrast, vaccination with an inactivated virus does not appear to impact fertility outcomes. These findings provide crucial guidance for physicians and infertile couples managing treatments during and after the pandemic, suggesting the need for extended recovery periods before ART procedures following COVID-19 infection.\n                  <\/jats:p>","DOI":"10.1017\/s0967199425100245","type":"journal-article","created":{"date-parts":[[2025,12,22]],"date-time":"2025-12-22T04:39:44Z","timestamp":1766378384000},"page":"285-294","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation of the impacts of COVID-19 infection and vaccination on the outcomes of assisted reproductive technology (ART) cycles"],"prefix":"10.1017","volume":"33","author":[{"given":"Farzaneh","family":"Shamlou Ahmadi","sequence":"first","affiliation":[{"name":"University of Science and Culture, ACECR"},{"id":[{"id":"https:\/\/ror.org\/02exhb815","id-type":"ROR","asserted-by":"publisher"}],"name":"Reproductive Biomedicine Research Center, Royan Institute for Reproductive Biomedicine, ACECR"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashraf","family":"Moini","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02exhb815","id-type":"ROR","asserted-by":"publisher"}],"name":"Reproductive Biomedicine Research Center, Royan Institute for Reproductive Biomedicine, ACECR"},{"name":"Tehran University of Medical Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arezoo","family":"Arabipoor","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02exhb815","id-type":"ROR","asserted-by":"publisher"}],"name":"Reproductive Biomedicine Research Center, Royan Institute for Reproductive Biomedicine, ACECR"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zahra","family":"Zolfaghari","sequence":"additional","affiliation":[{"name":"Reproductive Epidemiology Research Center, Royan Institute, ACECR"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bita","family":"Ebrahimi","sequence":"additional","affiliation":[{"name":"Reproductive Biomedicine Research Center, Royan Institute for Reproductive Biomedicine, ACECR"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9234-5318","authenticated-orcid":false,"given":"Firouzeh","family":"Ghaffari","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02exhb815","id-type":"ROR","asserted-by":"publisher"}],"name":"Reproductive Biomedicine Research Center, Royan Institute for Reproductive Biomedicine, ACECR"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2025,12,22]]},"reference":[{"key":"S0967199425100245_ref45","doi-asserted-by":"publisher","DOI":"10.1016\/j.rbmo.2021.06.006"},{"key":"S0967199425100245_ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.fertnstert.2021.12.032"},{"key":"S0967199425100245_ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.eclinm.2020.100670"},{"key":"S0967199425100245_ref9","doi-asserted-by":"publisher","DOI":"10.1093\/humrep\/deab238"},{"key":"S0967199425100245_ref37","doi-asserted-by":"publisher","DOI":"10.1016\/j.csbj.2021.04.061"},{"key":"S0967199425100245_ref8","doi-asserted-by":"publisher","DOI":"10.1002\/mrd.20060"},{"key":"S0967199425100245_ref54","doi-asserted-by":"publisher","DOI":"10.1002\/ijgo.13719"},{"key":"S0967199425100245_ref2","doi-asserted-by":"crossref","first-page":"150","DOI":"10.4103\/jhrs.jhrs_57_22","article-title":"Impact of COVID-19 pandemic on clinical and embryological outcomes of assisted reproductive techniques","volume":"15","author":"Banker","year":"2022","journal-title":"Journal of Human Reproductive Sciences"},{"key":"S0967199425100245_ref50","doi-asserted-by":"publisher","DOI":"10.1177\/1933719108327593"},{"key":"S0967199425100245_ref47","doi-asserted-by":"publisher","DOI":"10.1210\/endocr\/bqaa121"},{"key":"S0967199425100245_ref29","doi-asserted-by":"publisher","DOI":"10.1093\/molehr\/gaaa030"},{"key":"S0967199425100245_ref11","first-page":"858","article-title":"Could COVID-19 cause loss of sperm motility?","volume":"46","author":"\u00c7i\u00e7ek","year":"2021","journal-title":"Cukurova Medical\u00a0Journal,"},{"key":"S0967199425100245_ref40","doi-asserted-by":"publisher","DOI":"10.1080\/09513590.2021.1918080"},{"key":"S0967199425100245_ref27","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejogrb.2021.01.049"},{"key":"S0967199425100245_ref49","doi-asserted-by":"publisher","DOI":"10.1001\/jamanetworkopen.2023.23219"},{"key":"S0967199425100245_ref48","doi-asserted-by":"publisher","DOI":"10.3389\/frph.2022.1114308"},{"key":"S0967199425100245_ref55","unstructured":"World Health, O.
