Potential advantages and disadvantages of the time-lapse imaging method

Advantages	Disadvantages
Uninterrupted embryo culture	No robust evidence for improvement of primary outcome measures (CPR and LBR), and secondary outcome measures (IR, MR)[43]
Possibility of obtaining developmental data to select or deselect embryos	Standardization of terminology and annotation needed.
Excellent quality control and research tool	No definite concordance with ploidy status of selected embryos
Off-site data analysis
Patient counseling tool
Possible increase in IR, CPR and LBR; decrease in MR and TTP

IR=Implantation rate, CPR=Clinical pregnancy rate, LBR=Live birth rate, MR=Miscarriage rate, TTP=Time to pregnancy
