In my opinion it is nice to test as many embryos as you have. However, since we are talking about this test being applied and helping women above thirty eight or forty years of age, these are the women that have fewer oocytes, fewer embryo’s and fewer blastocysts developing. If they have an indication I would recommend this test even in a single embryo, however the reality of this test will help you when you test more than two to three embryos. So when you are testing more than three blastocysts, then you have a larger chance of having a normal embryo and a bigger chance of getting pregnant and a healthy baby. So this type of test is more helpful with more embryos that you have to test. There is no magic number and since you are testing aged embryos that come from aged women you will have less and less blastocysts formed.
