In Vitro Development of Embryos Derived from Vitrified-Warmed Oocytes is Delayed Compared to Embryos Derived from Fresh Oocytes: A Time-Lapse Sibling Oocyte Study

ConclusionsTiming of development is altered and blastocyst formation is delayed in embryos derived from vitrified-warmed donor oocytes compared to their fresh sibling counterparts. Although preliminary results suggest that the clinical impact of this delay may be limited, this needs further investigation in larger randomized studies.
