38 Year Old Has Five Failed Fresh IVF Cycles But Has Frozen Embies: Should She Try FET?
In terms of additional protocol changes, you are doing everything that I have my patients do in terms of supplemental medications, but I also add low dose heparin (2000 U per day). Not all RE's agree with this protocol, but it is an accepted protocol for recurrent pregnancy loss so you might want to ask your RE.
Thanks for following my Blog.

Second IVF Fails Despite Implantation: Thin Lining? Embryo Issue?
Before my first IVF I did a hysteroscopy and everything looked fine. I have a couple small intramural fibroids, none projecting into the uterine cavity. I had a big fibroid removed 4 years ago, but it was intramural and the endometrium was not touched during surgery.
So, in my last IVF that turned out as a chemical pregnancy, my endometrium was 7.1mm at the 6th day of stimulation with FSH (Bravelle), which was really encouraging. However, 2.5 days later, it decreased to 6.4mm... Because at that time I already had bid leading follicles, my doctor wanted to triger that night. He then injected into the uterine cavity, using a catheter, 300 ug of filgrastim (G-CSF), since there are two papers from Dr. Gletcher that mention it as a possible treatment for thin lining. My RE explained to me it was experimental and I agreed to try it.
48h latter and on the time of egg retrieval, my endometrium was 7.6mm. Still not ideal, of course, but the best I got in a long time, so my RE advised us to carry on with the transfer (2 beautiful 8-cell embryos).
So my questions are:
1)What is more likely to be the cause of the chemical pregnancy: genetically abnormal embryo or my thin lining?? I know my age is a factor, but I have been taking Coq10 for nearly a year now. My embryos always look good and I have 100% fertilization rate.
2) Also, I wanted to know if it is normal to have a 8-cell embryo at the end of day 2 (I collected the eggs on Mon 9am and the embryos were transferred Wed 6pm).
Taking my history into account, what would you recommend for my next FET in order to be suscessful in overcoming thin lining? Should I start to look into surrogacy?
As always, I really appreciate your time and expertise, and most of all the beautiful work you do here at your blog (for which I am a subscriber :) C. From Brazil
Answer:
Hello C. from Brazil, Thank you for your kind words and for following my blog! Let me answer your questions in sequence to make it easier.
1. If endometrial thickness were the problem, implantation would not have occurred. Technically, the minimum endometrial thickness required is 6.5 mms so your lining was adequate for implantation to occur, which did happen. The miscarriage was most likely a genetic issue considering your age. Unfortunately, we do not have a technology to evaluate internal egg quality nor change the quality. Keep in mind that the CoQ 10 study was in mice and not humans so we don't know if that will work or not.
2. An 8-cell embryo on D#2 is not normal. That is a rapidly dividing embryo and may indicate that it is genetically abnormal, as has been found on preimplantation genetic studies in the past. Division rate is one of the criteria I use to evaluate embryos, in addition to the external quality.
3. The endometrium does not decrease. The difference in widths are variations in ultrasound measurements. Because we are dealing with mms, the difference between 7.1 and 6.4 (0.6) is within the margin of error and not significant.
4. I cannot comment regarding the "filgrastim" as I am not familiar with this medication or its usage. I would recommend that you consider the frozen embryo transfer in a natural, unmedicated cycle, but I would follow a natural cycle without transfer first to evaluate if your body growth the endometrium to adequate width. Then if it does, I would schedule to make do the transfer in the next cycle. I would still use supplemental hormones after the transfer, namely progesterone to help support implantation and the early pregnancy.
5. If the FET fails, despite everything that has been done, the only other recommendation I could make, if you are still going to try your own eggs, is to have preimplantation genetic screening done (trophectoderm biopsy) on a Day #5 embryo. Some studies have shown increased pregnancy rates in older patients when embryos are screened for normal genetics. That will at least give you an indication on the genetic health of the embryos you are making and whether or not you should consider donor eggs. I would only recommend surrogacy if you are absolutely sure that you cannot get implantation and in your case, you've had implantation. I think it might be more of an embryo issue.
Good Luck,

Australian Undergoing Natural Cycle FET: Timing Is Everything!!!
Question:Hi Dr Ramirez, I am 32 from Australia. I am about to embark on my first Frozen Embryo Transfer, using my natural cycle. I have one child (5yrs old) who was conceived spontaneosly after removing my endometriosis 3 months earlier. My doctor will be conducting ultrasounds and blood tests to determine ovulation and progesterone levels. This starts on day 12. My embryos (which were all top rating) were frozen on day 2.
What is the latest time (post ovulation) they could transfer these soon to be 3 day old embryos? I'm just worried because 3-4 days post ovulation would most likely be on a Saturday or Sunday and the lab is not open on a Sunday. Is delaying it or doing it too early acceptable?
Thank you for your time. Kind Regards, Z. from Australia
Answer:
Hello Z. from Australia,
First let me say that I am very surprised that your doctor has chosen to do this with a natural cycle. Implantation is very time sensitive, meaning the timing of the transfer has to be pretty exact. If the development of the lining is out of sync with the embryo stage, then implantation will not occur. The timing of the endometrial lining development is very dependent on progesterone stimulation and that cannot be measured by blood tests because the blood levels do not reflect the endometrial levels or the endometrial architecture.
In terms of your question, I cannot believe that an IVF center would not be open on a Sunday if they have to be because of timing. Again, I know I'm being redundant, timing is EVERYTHING in a frozen embryo transfer. The embryos can be transferred at any cell stage, as long as it coordinates with the stage of endometrial development. In a normal cycle, the embryos are transferred one more day than the number of days you have been on progesterone. For example, for a Day 3 embryo, it is transferred on the 4th day of progesterone. For a Day 5 embryo, it is transferred on the 6th day of progesterone. What I would suggest for you, if the 3rd day falls on a Sunday and the clinic cannot do a transfer on that day, culture out the embryos until Day #5 and transfer at that time. They will have developed into blastocysts by then which might help your chances for implantation since the embryos will be closer to the stage they need to be in for implantation.

Woman Wonders: Natural FET Cycle Vs. Controlled FET Cycle?

Question:
Dr. Ramirez, I have some embryos frozen. I have adenomyois and endo and chronic endometritis diagnosed.
Have done antibiotic treatment with uterine lavages and IVs.
After depot lupron treatment, is it better to do a natural FET (frozen embryo transfer) or medicated FET. Since it takes about 2-3 months to wait for period to arrive is it better to do a medicated FET? I am concerned about medicated FET as the last time I did a medicated FET I had fluid in the uterus although nearer to transfer it disappeared and I did go on to transfer although BFN (big fat negative).
My RE seems to want to wait for a period before transfer but would not that waste 2-3 months since you said the endo can return in 6 months? Will the cycle be regular and as in ovulation or will it be not regular when I do FET. At the moment my cycles are regular. I have also heard of high dose progesteone treatments treating endo and adeno. Can you explain how this works?
I am confused what to do as we have limited embryos and want to do everything as possible as once the embryos are used up we are done.
Thank you. R. from Rhode Island
Answer:
Hello R. from the U.S. (Rhode Island),
Your RE should have explained that one of the critical steps in getting pregnant, natural or with IVF, is the state of the uterine lining at the time the embryo reaches it for implantation. We know that there is a very limited time that the embryo can implant and the endometrial lining has to be in a very specific and correct microscopic state for implantation to occur. This is where timing is absolutely essential. If you miss this "implantation window", then it will fail.
Conceivably you could do this with a natural cycle, but then there is a wider margin of error because we don't know exactly what the timing is or what is going on microscopically in the uterus. For this reason, we do not do this in FET cycles. FET cycles are always done as a controlled and programmed cycle. With this protocol, you can have a period induced artificially with medication and then start the cycle, but most clinics will want their patients to be on the birth control pill for at least two weeks period to the FET cycle in order to suppress the ovaries, which then allow complete control of the FET cycle.
If this is in fact gong to be your last attempts at getting pregnant, then I would make absolutely certain that you are in the best clinic that you can be in and that it will give you the highest chances of success. A good clinic would be able to answer these questions and make sure everything is clearly laid out.
Finally, in terms of progesterone treatment with endometriosis and adenomyosis, progesterone has suppressive action or counteracts estrogen in estrogen receptors. AS you probably know, endometriosis/adenomyosis are stimulated by estrogen and therefore, will be somewhat suppressed by progesterone. However, there is still some small amount of stimulation so progesterone is not the perfect treatment. Estrogen receptor blockers such as Lupron are better at suppressing endometriosis. Progesterone is used mainly to slow down the recurrence of the endometriosis after they have been treated with surgery or Lupron.

Patient Fails One Fresh, One Frozen IVF Cycle: Will Another FET Work?

Hello,
My name is S. from Boston. I am writing with a question regarding what I am going to be undergoing next week, a second frozen transfer. Just to give you some history, I had a first attempt successful IVF (in vitro fertilization) cycle in 2008 and delivered a healthy baby. We are now trying for baby #2 and had an unsuccessful fresh cycle, and an unsuccessful frozen cycle in the last few months. I still have several frozen embryos so my insurance is mandating that we use them prior to doing another fresh cycle.
I know the success rate is lower with frozen embryos but I wanted to know another opinion, if I should proceed with a fresh cycle if this one is negative. I have 3 frozen embryos left, that are all 6 cell and high implantation potential. I am not optimistic that this one will work, because the other two cycles they put in 2 8 cells and they didn't take. My doctor says there is no difference between 6 and 8 cell embryos, but if that is the case, then why do they always choose to transfer the 8 cells first? I know I could also lose some cells in the thawing process, so does that lower my chances more, and are there are risks associated with the baby, if I do become pregnant this cycle? Thank you so much!
Answer:
Hello S. from the U.S.,
These are very good questions that you should direct to your doctor. It is his/her responsibility to keep you informed.
Let me take the easy questions first. The reason why we use the 8 cell embryo first is because embryos are graded based on their appearance. Yes, that is we give them a higher grade, the better they look, just like a beauty contest. The cell number is the number of cells the embryo has divided into by that particular day, which I presume to be post-retrieval day#3. Again, we prefer embryos with more cells than less cells. That does not necessarily mean the embryos with more cells are BETTER than the embryos with less cells. In fact, preimplantation genetic testing often shows the opposite. So a higher number of cells does not guarantee a good embryo. The factors that make a good or perfect embryo are not things that we have the technology or knowledge to apply at this point in time. Maybe in the future. My preference is for my embryos to be between 6 cells and 8 cells at this point. Most pregnancies will result from embryos within this range, either grade I or grade II.
Frozen embryo transfers have a lower pregnancy rate probably because the lesser embryos are left to be frozen and the better embryos are transferred fresh. Also, it may be because of the freeze and thawing of the embryos, but the technique has gotten so good that I don't think that is much of a factor any more. But, that does not mean that a frozen embryo can't implant and produce a good pregnancy. I would still recommend that you use them first before another fresh cycle because the medications required are less, AND there are some studies that show that implantation is better if there is no ovarian stimulation, as in Donor cycles. That might be an advantage. You just have to hope that the embryos are still good enough.
I might suggest that you ask your doc to culture the embryos remaining to blastocyst stage. That will be a further validation of the embryos, and may lead to fewer embryos to transfer, but they will be at a stronger stage. That does not necessarily give you a better chance at pregnancy, but the assumption is that if the embryo can survive further culturing then it has a better chance of continuing to implantation. That way, you can further screen the remaining embryos that you have. The ones that don't make it to this point will be discarded, then you will need to move to a fresh cycle. If you have extra blastocysts, you should only transfer two max at this stage, they can be frozen and are in a better stage for the freezing.Finally, there are no added risks for a normal baby if by frozen eggs or embryos. If the embryos are abnormal they usually will not work (implant) or will end in miscarriage. You have not given your age, but this can be a factor in terms of embryo quality, success and genetic risks as well if you are 35 years old or older.

Estrogen Patches Vs. Estrogen Injections: Which Is Better For Pregnancy Success?

I have four frozen embryos which I would like to have transferred. My question is what has a better success rate with prepping the uterus, the Vivelle dot 0.1mg patches vs. the delestrogen injections? I had a baby two years ago from a donor egg and how they prepped me was with the delestrogen. I have since moved away from that IVF Clinic who used this protocol. I have recently consulted with a different clinic where I presently live and they would rather use the patches.
