What treatment do you offer for people who have had unsuccessful treatment in the past?

Part of our evolution of IVF, and what we're trying to do in developing this next generation, is also trying to understand even why the best embryos fail, why some of them miscarry. For example, the care group have been working uniquely on a gene, which we know has a risk of causing either miscarriage, or failure of the embryo to implant in the womb, or indeed problems with the growing foetus during the pregnancy. This gene, we call C4M2, it's not a very exciting name, is simply because it's a mutation which is called M2 that sits on a gene in chromosome four. This chromosome four gene with the M2 mutation, we now know is a risk associated factor in couples. I say couples because it's the first time it's ever been shown for a gene to exist in a man that can cause a miscarriage in the woman. If the man has it, he could pass it on to the embryo. The embryo, then will have a problem, either an implantation, or maybe miscarrying, or potentially in the placenta it produces causing problems with the developing foetus. C4M2 is part of one of the next generational approaches we have to looking at one of the other issues about IVF and conception in general, not just IVF. That is not just making a viable embryo, but being able to hold onto it and deliver it to term.
