 Methods The current study will be a prospective randomized and double-blinded study using three patient arms. The first arm will include patients randomized to embryo culture in a tri-gas bench incubator Miri, Benchtop Multi-room incubator. These embryos will undergo multiple evaluations using light microscopy and traditional morphologic assessment according to accepted criteria. The second arm will include patients randomized to embryo culture in a time-lapse incubator Miri TL, Time-Lapse Incubator. These embryos will remain in the TLI and undergo both morphologic and morphokinetic evaluation and grading according to a multivariable scoring model. They will not be removed from incubation for the duration of culture. The third arm will include patients also randomized to embryo culture in a time-lapse incubator Miri TL, Time-Lapse Incubator. These embryos will remain in the TLI and undergo only traditional morphologic assessment according to accepted criteria with no additional imaging. They will also not be removed from incubation for the duration of culture. The time points and evaluated parameters will be identical to those in arm 1 of the study.
