Subject: IVF implantation failure; luteal phase brown spotting, even with high progesterone levels Date
Question:
Dear Dr. Ramirez,
I have found your responses to others extremely helpful!
I am 35 years old and am writing from Hungary. My husband and I've just finished our second, unsuccessful round of IVF with ICSI; both were 5th-day transfers with a good quality pair of embryos in each. My husband had had two samples frozen before his BMT several yrs ago, which is what we used for the IVFs--it looks like now he occasionally has a nonmotile cell or two, but not much else.
I would very much appreciate your thoughts and advice on luteal phase issues, including luteal phase support during IVF, given a potentially short luteal phase and pre-cycle brown spotting.
The first round of IVF, I got progesterone suppositories, but my prog. level was fluctuating with that (was as low as 18.85 9 days post-transfer, and was up to 43 3 days later). As a result, bleeding started 7 days post-transfer.
For the second IVF (with frozen embryos), I got progesterone injections instead, which kept my prog. level up (56, 65). Nonetheless, I still had definite brown spotting starting 4 days post transfer, gradually turning rust-colored. Both transfers, I had mild cramps on days 2 and 3 after the transfer.
As we were making preparations for the IVF, my fertility doctor determined that I have a relatively short luteal phase despite the fact that my cycles are 28-31 days long: I ovulate on the 17th-21st day (20th is typical). In addition,
for the past three years, my period has always been preceded by 1-4 days of brown spotting. And *including* those spotting days, my luteal phase has been 9-12 days long throughout 2009 (13 days when I was on Suprefact for the ovarian stimulation).
A further detail that could be relevant: I have an autoimmune thyrod disorder that is being monitored, no medications for it. My anti-TPO level is 1516 and I have a thyroid cyst about 3x2x3 cms in size, the biopsy was negative. My thyroid levels have been normal: TSH 0.65-1.2, T4 15.6.
Any thoughts on what might be behind the persistent pre-cycle spotting, despite the high prog. levels with the injections, and what can be done about it?
I would like to do all I can to exclude the possibility that the embryos did not implant because of a luteal-phase- related issue, especially because the number of chances
we've got are limited. Do you have any suggestions what might be worth asking about, any variations on the protocol, any further tests? Right now, the plan is to do the 3rd IVF round--with potentially the last batch of frozen sperm--with the same luteal phase support as before: ovitrelle for the ovulation and prog injections, following a stimulation phase consisting of suprefact and gonal-f 150. I am told that
based on my low HCG level ( 0.1) measured at 12 days post transfer, the embryos did not even begin to implant in either of the previous rounds. So the spotting in this
second round wasn't due to implantation then.
Also, I have read about taking vitamin B6 for luteal phase defect, my doctor here says he doesn't know about that helping with the short luteal phase and the spotting. What are your thoughts on the matter?
I very much appreciate your time and help.
Yours sincerely,
Sophie
Answer:
Hello,
Thank you for all the information and the very well written letter. I can't even tell that you are from Hungary. Your English is perfect!
First of all, despite the fact that you may have had a luteal phase defect in the past, the purpose of the progesterone after retrieval is to treat for possible luteal phase defect. Therefore, you don't have a luteal phase defect with your IVF cycles, and this is NOT the reason for the implantation failure. Something else must be going on. You don't mention the quality of the embryos, but that would be one question. Also, you don't mention how many were retrieved, how many fertilized, how many did not make it to blastocyst and how many were frozen. I presume there were none to freeze since you don't mention it.
Implantation failure is a difficult problem because we are not able to distinguish all the processes required for implantation, and there are not tests to help. The only current test available, b-Integrins, don't help because the treatment is to use more progesterone. I would do that any way. Please read more on implantation failure and recurrent miscarriage here: "Recurrent Pregnancy Loss".
My approach to patients with implantation failure is to add the following medications:
1. Aspirin 81 mg per day beginning at the start of the cycle.
2. Heparin 2000 units twice per day beginning at the start of the cycle.
3. Medrol 16 mg daily until transfer then 8 mg from that point until positive pregnancy, then stop.
4. Increase progesterone to 50 mg injection plus Endometrin 100 mg twice per day vaginally. The injections starts on the day of the retrieval and the suppositories start the day after the transfer.
This regimen covers most immune responses that might prevent implantation, as well as, any micro-clots that form at the site of implantation. It is used mainly in patients that have recurrent miscarriages, but has proved useful in IVF as well. You might want to suggest this to your doctors. This regimen is unproven and controversial, however. Another suggestion would be to transfer at day # 3 instead of going to blastocyst. Blastocyst culturing is not perfected, and I still believe that the uterus is a much better culture media and incubator that the lab.
Also keep in mind that pregnancy rates are very clinic dependent. There is a wide variety of pregnancy rates between clinic, and the rates can very much be influenced by the laboratory environment, the physician skill doing the transfer and the stimulation and culture protocols. One option might be to try a different clinic. I recently changed my clinic location and our pregnancy rates are much better than before because we were able to build a better facility.
Good Luck,
