What that means: Using hCG alone: Traditionally, hCG is the most common hormone used to trigger eggs to mature fully so that they can be collected for fertilization. Adding GnRHa: GnRHa is another medication that mimics a natural hormone produced by the brain. Adding this as a co-trigger may do better than just using hCG alone, by leading to more mature eggs and increasing live birth rates (LBRs). However, concerns about added costs and inconvenience remain. To address this, we created a cost model comparing LBRs and costs between the two strategies. Our analysis found that using this dual trigger increased LBRs by 13%, with a small cost increase of $175. For each 1% higher LBR, the added cost of using GnRHa + hCG was $13. Considering this minimal increase in cost relative to the overall high cost of IVF, using the dual trigger appears to be a cost-effective strategy to improve success rates for patients.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1530\/raf-24-0095","type":"journal-article","created":{"date-parts":[[2025,1,20]],"date-time":"2025-01-20T09:55:46Z","timestamp":1737366946000},"update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-13","source":"Crossref","is-referenced-by-count":1,"title":["A cost analysis of hCG trigger alone versus dual trigger for achieving live birth following\n                    <i>in vitro<\/i>\n                    fertilization"],"prefix":"10.1530","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7593-3719","authenticated-orcid":true,"given":"Esther H","family":"Chung","sequence":"first","affiliation":[{"name":"Stanford Fertility and Reproductive Health , , ,","place":["Sunnyvale, California, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arian","family":"Khorshid","sequence":"additional","affiliation":[{"name":"Stanford Fertility and Reproductive Health , , ,","place":["Sunnyvale, California, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brindha","family":"Bavan","sequence":"additional","affiliation":[{"name":"Stanford Fertility and Reproductive Health , , ,","place":["Sunnyvale, California, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruth B","family":"Lathi","sequence":"additional","affiliation":[{"name":"Stanford Fertility and Reproductive Health , , ,","place":["Sunnyvale, California, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"416","published-online":{"date-parts":[[2025,1,20]]},"reference":[{"key":"2026070713192603500_bib1","doi-asserted-by":"crossref","DOI":"10.1016\/j.jogoh.2020.101728","article-title":"Dual trigger using recombinant HCG and gonadotropin-releasing hormone agonist improve oocyte maturity and embryo grading for normal responders in GnRH antagonist cycles: randomized controlled trial","volume":"49","author":"Ali","year":"2020","journal-title":"J Gynecol Obstet Hum Reprod"},{"key":"2026070713192603500_bib2","doi-asserted-by":"crossref","first-page":"1648","DOI":"10.1093\/humrep\/deaa107","article-title":"GnRH agonist and hCG (dual trigger) versus hCG trigger for final follicular maturation: a double-blinded, randomized controlled study","volume":"35","author":"Haas","year":"2020","journal-title":"Hum Reprod"},{"key":"2026070713192603500_bib3","doi-asserted-by":"crossref","first-page":"78","DOI":"10.1186\/s12958-021-00766-5","article-title":"GnRH agonist and hCG (dual trigger) versus hCG trigger for follicular maturation: a systematic review and meta-analysis of randomized trials","volume":"19","author":"Hu","year":"2021","journal-title":"Reprod Biol Endocrinol"},{"key":"2026070713192603500_bib5","article-title":"Prescription Prices, Coupons & Pharmacy Information","author":"GoodRx","year":"2022"},{"key":"2026070713192603500_bib4","first-page":"63","article-title":"Combined administration of gonadotropin-releasing hormone agonist with human chorionic gonadotropin for final oocyte maturation in GnRH antagonist cycles for in vitro fertilization","volume":"59","author":"Kim","year":"2014","journal-title":"J Reprod Med"}],"container-title":["Reproduction and Fertility"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/raf.bioscientifica.com\/view\/journals\/raf\/6\/1\/RAF-24-0095.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/raf.bioscientifica.com\/downloadpdf\/journals\/raf\/6\/1\/RAF-24-0095.xml","content-type":"text\/html","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/journals.bioscientifica.com\/raf\/article-pdf\/doi\/10.1530\/RAF-24-0095\/146967\/raf-24-0095.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/journals.bioscientifica.com\/raf\/article-pdf\/doi\/10.1530\/RAF-24-0095\/146967\/raf-24-0095.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,7]],"date-time":"2026-07-07T17:49:50Z","timestamp":1783446590000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.bioscientifica.com\/raf\/article\/6\/1\/e240095\/26229\/A-cost-analysis-of-hCG-trigger-alone-versus-dual"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,1,1]]},"references-count":5,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2025,1,1]]}},"URL":"https:\/\/doi.org\/10.1530\/raf-24-0095","relation":{},"ISSN":["2633-8386"],"issn-type":[{"value":"2633-8386","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,1,1]]},"article-number":"e240095"}}
