Claim Text:
1. A method for selecting a human embryo for transfer or cryopreservation based on an evaluation of quality of embryo growth in vitro, comprising: measuring an imaging parameter (P3) of the time between 3rd and 4th cell or second and third mitosis of the test embryo and measuring at least one imaging parameter selected from: (P4) time between 4th and 5th cell; (P5) time between 5th cell and compaction and (P6) time between 5th cell and cavitation; comparing the P3 imaging parameter and the at least one imaging parameter from the test embryo to a reference imaging parameter; determining whether the imaging parameters from the test embryo differs from the reference imaging parameters, wherein the P3 reference imaging parameter is less than about 1 hour, the reference P4 is about 15 hours, the reference P5 is less than about 28.6 hours, the reference P6 is less than about 66.4 hours; wherein a difference indicates a lack of embryo quality; providing an evaluation of the test embryo quality based on comparison and determination; and selecting an embryo for transfer or cryopreservation based on the evaluation of quality.
