207ItIs:
A.2 Two of the chemical pregnacies were intrauterine. The embryo attached to the endometrium, initiated implantation, but did not continue to develop. That could have been a result of (a) embryo genetics (I'll address the PGD issue below) and/or (b) problems with the endometrium. Your RE says everything looks "fine". In that conterxt, what does "everything looks fine" mean? It means that the ultrasound of your uterus showed an adequate endometrial thicknes at the time of hCG. Endometrial thickness is only one measure of "everything" and does not address any issues at the molecular level of embryo-endometrium interaction. After 3 chemicals, it looks like something is going wrong with embryo-endometrium interaction. You have ruled out blood clotting problems. At our current level of understanding of the implantation process, that only leaves one explanation - immunological rejection of the embryo. O.K. ,so your RE is not a "believer" that the immune system is involved in early miscarriage. That's fine. Everyone is entitled to their opinion, but telling a 32 year old patient that, after failing a fresh IVF cycle with the highest grade blastocysts and three FETs with frozen-thawed blastocysts of good quality, that its just the "luck of the draw" is pretty lame. If that's the case, you are very unlucky indeed. I think its really, really, really time for a second opinion. And even if your program is the best program in the world and your doctor's the greatest IVF doctor on the planet, it is still time for a second opinion. You're getting nowhere fast at this program.
A3. Its clinical. Dr. Miller will answer.
A4. I think it is highly unlikey that PGD will increase your chances of pregnancy. PGD is a very crude tool to evaluate the genetic normalacy of an embryo. At best, it can evaluate 11/23 chromosomes to determine if there are pairs of each of the 11 chromosome (evaluation for anueploidy). What about the other 12 pairs? What if the problen does not involve an abnormal number of chromosomes? What if its a genetic translocation? What if the results from the embryo biopsies are inconclusive? What if they are simply wrong (PGD accuracy is not 100%)? Secondly, your problem does not appear to be related to anueploidy. Most (but not all) anueploidies are screened out before reaching the blastocyst stage and those anueploid embryos that do reach the blastocyst stage often have too few stem cells to continue development. These embryos can be identified and "weeded out " prior to transfer. All your blastocyst stage embryos had an adequate number of stem cells as indicated by their grades (even the 4BB is fine). In my opinion, PGD is not where the money is, although that's where yours will be. PGD is not cheap.
A5. The management of the stimulation by the RE, not the brand of medications, is what makes a difference in implantation rate. If your RE thinks you did fine (and I think you did too), there's no need to change.
A6. Failed FETs do not count as a failed IVF cycle. They count only as a failed FET. In the context to which you refer, you have had one failed IVF cycle. However, in view of your repeated chemical pregnancies (fresh and FET), it is clear that something's going on that's not just the luck of the draw.
