A method for characterizing an embryo or organ is provided and comprises: capturing images of the embryo over a time period, either continually or at intervals by means of photography, video, ultrasound or infra-red imaging, determining characteristics of the pattern of movement of the embryo and comparing the determined characteristics with reference data relating to the expected movement pattern of the subject embryo. The method is of use in the staging of embryos and in analysing an environment to which the embryo has been exposed. Chararcterising features that may be measured are the developmental stage of the embryo, rotational movement of the embryo and the centre of mass of the embryo. |
