Who is suitable for next generation IVF?

The label Next Generation IVF begs the question of is there a difference in suitability for patients? In many ways that depends on what we are using in our Next Generation IVF technologies, which are going to be a combination of technologies. It's going to be quite a different approach, as always if it's precision-based by definition, for each individual patient. If we take for example PGS, the chromosome screening part of Next Generation IVF, are all patients suitable for it? Potentially yes, because all patients will have a different number of embryos and some will be chromosomally normal, some won't. If a patient only has two embryos, do we want to screen them? Some doctors, and I know some in the States particularly, won't put any embryo back unless it's screened for two reasons. One, they want to absolutely find out if they are chromosomally normal or not. Two, it's providing additional information to the patient. Another doctor may say, Well, if there's only two embryos, why go to the cost of doing the genetic testing? Just transfer the two embryos. There are different approaches as to whether everything that we've got in our evolving Next Generation bucket is applicable to all patients. I would say it's very much, as is the definition of precision-based approach, specific to each individual patient.
