Slow freezing, vitrification and ultra-rapid freezing of human embryos: a systematic review and meta-analysis.
Embryo cryopreservation is an important aspect of assisted reproduction. Many methods have been described, but they have been poorly investigated in randomized trials, highlighting the need for a systematic review of the literature. Meticulous electronic/hand searches were performed to locate randomized trials (RCT) comparing embryo cryopreservation methods. Primary outcomes were clinical pregn...
متن کاملTranscriptomic difference in bovine blastocysts following vitrification and slow freezing at morula stage
Cryopreservation is known for its marked deleterious effects on embryonic health. Bovine compact morulae were vitrified or slow-frozen, and post-warm morulae were cultured to the expanded blastocyst stage. Blastocysts developed from vitrified and slow-frozen morulae were subjected to microarray analysis and compared with blastocysts developed from unfrozen control morulae for differential gene ...
متن کاملCryopreservation of human embryos by vitrification or slow freezing: a systematic review and meta-analysis.
OBJECTIVE To examine the literature systematically in order to identify prospective comparative trials answering the following question: Is vitrification of human embryos associated with a higher postthawing survival rate as compared with slow freezing? DESIGN Systematic review and meta-analysis. SETTING University-based hospital. PATIENT(S) Not applicable. INTERVENTION(S) Vitrification...
متن کاملClinical outcomes following cryopreservation of blastocysts by vitrification or slow freezing: a population-based cohort study.
STUDY QUESTION What are the clinical efficacy and perinatal outcomes following transfer of vitrified blastocysts compared with transfer of fresh or of slow frozen blastocysts? SUMMARY ANSWER Compared with slow frozen blastocysts, vitrified blastocysts resulted in significantly higher clinical pregnancy and live delivery rates with similar perinatal outcomes at population level. WHAT IS KNOW...
