Why IVF Doesn't Work, Is It Genetically Normal?

Before you decide which embryo to put in, you can sort of select out which ones are genetically, i guess, better. One of the most common reasons why people miscarry is because the genetics, or the chromosome numbers of the embryos are not correct. So there's wrong number of chromosome that code for everything that makes us human. And so if we can actually find these genetically normal embryos from a chromosome we can focus our energy on those and potentially have better outcomes than putting in embryos where we don't have that information.
