Impact of Group vs Individual Embryo Culture Strategies on Blastocyst and Clinical Outcomes
Embryo culture is one of the most important steps in an assisted reproduction laboratory. Embryos can be cultured individually, one embryo per media...

Evaluating the heterogeneous effect of extended culture to blastocyst transfer on the implantation outcome via causal inference in fresh ICSI cycles
PurposeIn IVF treatments, extended culture to single blastocyst transfer is the recommended protocol over cleavage-stage transfer. However,...

Prioritized single vitrified blastocyst to be warmed between grades 3 or 4 blastocyst on day 5 transfer cycles
PurposeSelecting the optimal blastocyst to implant during cryopreservation and warming is critial for in vitro fertilization success. Therefore, the...

Extending the culture of cleavage-stage embryos to the blastocyst stage after warming increases the chance of live birth: does it have a regenerative effect?
PurposeWe aimed to evaluate the effect of extending the culture of cleavage-stage embryos to the blastocyst stage in vitrified–warmed cycles on...

Interleukin-6 Concentration in Single-Embryo Medium Is Associated with Blastocyst Formation
IL-6 plays an important role in oogenesis in humans. However, at the preimplantation stage, IL-6 production and the role in embryo development remain...

Comparative Assessment of Survival and Clinical Outcome Between Two Commercial Vitrification Kits with Different Warming Protocols After Blastocyst Culture: Potential Perspectives Toward Simplified Warming Procedures
This study investigates whether there is an effect on laboratory results and clinical outcome using commercial kits with similar vitrification but...

Estrogen signaling encourages blastocyst development and implantation potential
PurposeEstrogen is well-known for preparing uterine receptivity. However, its roles in regulating embryo development and implantation are unclear....

Comparison of pregnancy and live birth rates between fresh day 5 morula transfer and fresh day 6 blastocyst transfer following extended culture for slow growing embryos
PurposeThe aim of this study is to evaluate and compare the outcomes of fresh day 5 morula transfers and fresh day 6 blastocyst transfers after...

Effect of time post warming to embryo transfer on human blastocyst metabolism and pregnancy outcome
PurposeThis study is aiming to test whether variation in post warming culture time impacts blastocyst metabolism or pregnancy outcome.

Effect of blastocyst shrinkage on assisted reproductive outcomes: a retrospective cohort study describing a new morphological evaluation of blastocyst pre-vitrification and post-warming
BackgroundThe failure of frozen-thawed blastocysts to re-expand adequately within a few hours after warming has been reported to have a negative...

Extended culture of cleavage embryo to blastocyst embryo is among the good predictors of successful outcome in vitrified-thawed ICSI cycles
BackgroundPrevious studies showed that top-quality embryo transfer (ET), number of transferred embryos, endometrial preparation with natural cycles...

Fresh or frozen day 6 blastocyst transfer: is there still a question?
BackgroundThe Live Birth Rate (LBR) after day 5 (D5) blastocyst transfer is significantly higher than that with D6 embryos in both fresh and...
-
Individual culture leads to decreased blastocyst formation but does not affect pregnancy outcomes in the setting of a single, vitrified-warmed euploid blastocyst transfer
PurposeTo evaluate embryology and pregnancy outcomes following individual and group embryo culture in the setting of contemporary laboratory...

Noneffectiveness of cryostorage duration on clinical and neonatal outcomes after single vitrified-warmed blastocyst transfers
BackgroundIn the current era of assisted reproductive technology, the strategy of single vitrified-warmed blastocyst transfer (SVBT) is acknowledged...

Competent blastocyst and receptivity endometrium improved clinical pregnancy in fresh embryo transfer cycles: a retrospective cohort study
BackgroundEmbryo quality is usually regarded as a key predictor of successful implantation and clinical pregnancy potential. The identification of...

Granulocyte–macrophage colony-stimulating factor-containing medium treatment after thawing improves blastocyst-transfer outcomes in the frozen- thawed blastocyst-transfer cycle
PurposeTo determine whether granulocyte–macrophage colony-stimulating factor (GM-CSF)-containing medium could improve embryo-transfer outcomes in...

Developmental competence and neonatal outcomes of nonpronuclear zygotes following single vitrified-warmed blastocyst transfers using propensity score matching analysis
PurposeTo investigate developmental competence and neonatal outcomes of nonpronuclear (0PN) zygotes following single vitrified-warmed blastocyst...

Total gonadotropin dose did not affect euploid blastocyst rates: an analysis of more than 19,000 oocytes
BackgroundTo evaluate whether increasing total gonadotropin (Gn) dose is associated with changes in euploid blastocyst rate in preimplantation...
