Claim:
A method for selecting one or more human embryos that is likely to reach the blastocyst stage comprising: culturing one or more human embryos under conditions sufficient for embryo development; time lapse imaging said one or more embryos for the duration of at least one cytokinesis event or cell cycle; measuring at least one cellular parameter comprising: (a) the duration of the first cytokinesis; or (b) the time between the first and second mitosis; or (c) the time between the second and third mitosis; and selecting an embryo when said at least one cellular parameter falls within: (i) a duration of the first cytokinesis that is about 0 to about 33 minutes; or (ii) a time between the first and second mitosis that is about 7.8 to 14.3 hours; or (iii) a time between the second and third mitosis that is about 0 to 5.8 hours; thereby selecting an embryo that is more likely to reach the blastocyst stage.
