does not use a static form of observation to evaluate a highly dynamic process. High resolution images obtained at frequent time points provides greater detail of the events involved in embryo development. This higher degree of detail and parameters used to assess embryo viability reduces the biased variability in embryo selection by an embryologist, allowing for a more standardised method of embryo quality evaluation and selection for implantation. This also provides a quantifiable method for analysis rather than just qualitative. Clinicians are given more time to evaluate an image rather than a time pressured evaluation of an embryo which must be quickly put back into incubation; resulting in a reduced degree of human error. Potential damage to otherwise viable embryos is also reduced due to minimized fluctuation of optimal culture conditions . These factors such as pH and temperature, if altered, have been shown to influence preimplantation development of a blastocyst. Both the mother and child may benefit from this new method of IVF treatment. Transfer of the single, highest potential embryo into the mother reduces the likelihood of multiple gestations, which limits future complications such as preterm labour. This method reduces time spent and consequently lowering overall costs. Greater understanding and evidence for embryo morphokinetics can help improve current knowledge of embryo development and factors influencing successful clinical pregnancy outcome. Limitations Although morphokinetics has its advantage in terms of selecting embryos for implantation, the technology is unable to deselect all abnormal embryos. There is also a struggle to find a universal algorithm as attempts to validate published algorithms have proved unsuccessful. More work needs to be done in the scientific community, working as a cohesive unit to define the best possible algorithm that could lead to a single successful pregnancy. The benefits of using morphokinetics in terms of improving clinical outcomes of IVF is still very unclear. A meta-analysis published in 2017, supported the idea of clinical benefits of time-lapse culture with morphokinetic embryo selection in IVF, reporting reduced early pregnancy loss, higher ongoing pregnancy and higher live birth rates. However, the studies included in the meta analysis were carried out in selected populations and were of dubious quality, meaning we can not rely on this as conclusive evidence that IVF outcomes are improved by using morphokinetic embryo selection and time-lapse technology instead of standard morphological evaluation. Apart from this, there is limited reviewed evidence to support the clinical
