Recent advances in the field of assisted reproductive technology (ART) have called into question the timing and frequency of COS monitoring appointments, as discussed in this commentary.<\/jats:p>","DOI":"10.1007\/s10815-024-03182-x","type":"journal-article","created":{"date-parts":[[2024,7,4]],"date-time":"2024-07-04T00:01:44Z","timestamp":1720051304000},"page":"1715-1717","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Monitoring of controlled ovarian stimulation in IVF"],"prefix":"10.1007","volume":"41","author":[{"given":"Shahar","family":"Kol","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan Carlos","family":"Castillo Farfan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark P.","family":"Trolice","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9644-2115","authenticated-orcid":false,"given":"Alexander M.","family":"Quaas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,7,4]]},"reference":[{"issue":"1","key":"3182_CR1","doi-asserted-by":"publisher","first-page":"58","DOI":"10.1093\/humrep\/dex334","volume":"33","author":"\u00c5 Magnusson","year":"2018","unstructured":"Magnusson \u00c5, K\u00e4llen K, Thurin-Kjellberg A, Bergh C.
