Methods: A prospective pilot, randomized, controlled, double-blinded, single-center study was conducted during the years 2016\u20132020. In total, 102 patients were randomized into three groups: (1) conventional incubation with morphological evaluation only (n = 34), (2) TLI with both morphological and morphokinetic evaluations (n = 32), and (3) TLI with morphological evaluation only (n = 36). All arms were cultured in ESCO-MIRI\u00ae incubators. A total of 1061 injected mature oocytes were evaluated (420 in arm 1, 285 in arm 2, and 356 in arm 3). The primary outcome was live birth rates. Secondary outcomes included clinical and cumulative pregnancy rates as well as embryo quality. Embryos in arm 3 were retrospectively evaluated for their morphokinetic score. Results: No significant difference was found in the live birth rate for single embryo transfer cycles (SET) (35% vs. 31.6% vs. 24%, p = 0.708) or double embryo transfer (DET) cycles (41.7% vs. 38.5% vs. 36.4%, p = 0.966). Comparable pregnancy rates, clinical pregnancy rates, and cumulative pregnancy were found for similar top-quality embryos for days 2, 3, and blastocyst stages across groups. A similar number of embryos were suitable for either transfer or cryopreservation within the different groups. For 62.8% of the embryos in arm 3, the morphokinetic and morphologic evaluations were similar. In only 2\/36 (5.6%) treatment cycles, the use of morphokinetic scoring may have helped the patient avoid undergoing an additional treatment cycle. In the other cases, morphokinetic scoring would not have changed the end point of pregnancy. Conclusions: The two components of the TLI system\u2014undisturbed culturing and morphokinetic embryo grading\u2014do not appear to have a significant additional value in reproductive outcome, although these results should be validated by an RCT.<\/jats:p>","DOI":"10.3390\/jcm13061701","type":"journal-article","created":{"date-parts":[[2024,3,15]],"date-time":"2024-03-15T12:02:39Z","timestamp":1710504159000},"page":"1701","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Time-Lapse Incubation for Embryo Culture-Morphokinetics and Environmental Stability May Not Be Enough: Results from a Pilot Randomized Controlled Trial"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-3439-6348","authenticated-orcid":false,"given":"Gilat C.","family":"Sacks","sequence":"first","affiliation":[{"name":"Shaare Zedek Medical Center, In Vitro Fertilization Unit, Jerusalem 9103102, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henny","family":"Mozes","sequence":"additional","affiliation":[{"name":"Shaare Zedek Medical Center, In Vitro Fertilization Unit, Jerusalem 9103102, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruth","family":"Ronn","sequence":"additional","affiliation":[{"name":"Shaare Zedek Medical Center, In Vitro Fertilization Unit, Jerusalem 9103102, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Talia","family":"Elder-Geva","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Hebrew University of Jerusalem, Jerusalem 9112001, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oshrat","family":"Schonberger","sequence":"additional","affiliation":[{"name":"Shaare Zedek Medical Center, In Vitro Fertilization Unit, Jerusalem 9103102, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ido","family":"Ben-Ami","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Hebrew University of Jerusalem, Jerusalem 9112001, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0488-9313","authenticated-orcid":false,"given":"Naama","family":"Srebnik","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Hebrew University of Jerusalem, Jerusalem 9112001, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Practice Committee of the American Society for Reproductive Medicine, and Practice Committee for the Society for Assisted Reproductive Technologies (2021).
