Results • 13 papers • Heterogeneity of morphokinetic and conditions (culture media, mode of fertilization, day of ET)
Results • Only one study demonstrated significantly improved clinical pregnancy rates when embryos were selected by TLM in addition to conventional morphology
Conclusion • While TLM has the potential to revolutionize clinical embryology, there are currently no high-quality data to support the clinical use of this technology for selection of human preimplantation embryos.
Conclusions • reliable prediction of blastocyst conversion based on early morphokinetic markers may be the main advantage of TLM. • Surprisingly few data, however, indicate whether TLM effectively distinguishes between embryos with high and low implantation potential
Conclusions • Our intent in writing this review is not to discourage further research regarding the clinical utility of TLM for embryo selection, but rather, quite the opposite: we hope to cast light on unresolved questions and inconsistencies in current nomenclature in order to motivate future appropriately designed studies
Time-lapse embryo imaging for improving reproductive outcomes: asystematic review and meta-analysis US ObstetGynecol 2014 • we only included RCTs comparing time-lapse embryo imaging versus standard embryo monitoring
Results • 2 RCT were included • A total of 138 women : 68 were allocated for time-lapse monitoring system and 70 were allocated for conventional incubation (EmbryoScope, Primo Vision time-lapse system)
Results • Clinical pregnancy: The pooled estimate was not sufficiently precise to identify whether TLM causes a small benefit, no effect or small harm: RR 1.05, 95% CI 0.80 to 1.38, P = 0.73
There is no evidence from RCTs about the effect of TLM on live birth. • The current evidence from available RCTs shows that TLM does not cause a large change on the chance of achieving clinical and/or ongoing pregnancy when transferring blastocyst stage embryos
Future directions • An ideal study- measure implantation rates among patients randomized to SET following: a) embryo culture in a TLM with selection based on conventional morphology alone b) embryo culture in a TLM with selection based on morphokinetic parameters plus conventional morphology
the ESHRE stated that the aim of IVF treatments is the birth of a single neonate, while a multiple pregnancy is considered a complication of IVF treatment
