Patent ID: 8721521

Claim:
A method for selecting a human embryo comprising: (a) culturing a human embryo in vitro under conditions sufficient for embryonic development; (b) imaging said human embryo by time lapse microscopy wherein images are captured at time intervals necessary to detect one or more cellular parameters comprising, the time interval between cytokinesis 1 and cytokinesis 2; (c) analyzing said images to arrive at a measurement of said one or more cellular parameters; (d) assessing the developmental potential of the human embryo from said one or more cellular parameter measurements to determine if the embryo has good developmental potential or poor developmental potential, wherein the human embryo is determined to have good developmental potential when the time interval between cytokinesis 1 and cytokinesis 2 is about 8-15 hours or poor developmental potential when the time interval between cytokinesis 1 and cytokinesis 2 lasts more than about 15 hours or less than about 8 hours; and (e) selecting an embryo with a good developmental potential for transfer into a female recipient or selecting an embryo with poor developmental potential for nontransfer.
