Anticipated outcomes and potential pitfalls. The number of patients needed for the study is reasonable and we do not expect it to be an obstacle. If the results in this study will be to the animal study we should be able to show a significant difference in the number of euploid embryos between the test and control groups, as well as with the other outcome parameters. We have been working for several months with the UHN microarray lab to optimize the use of the Advalytics multiplex PCR kit which currently works very well. We do not expect any problems with this component of the object.
