Hello cutecutetown,
I am doing 2nd IVF cycle (1st in Taiwan with 5 day5 embryos left). First failed implantation and second missed miscarriage at 8w after heartbeat seen at 6w. No PGS. Did biopsy after d&c and suprisingly results shows embryo is normal karyotype…I would like to seek your advice:
1) Should I do PGS on the remaining 3 frozen embryos (2 day5 and 1 day6) or just continue to transfer them?
2) Similarly, should I thaw and do PGS on the frozen embryos in Taiwan?
3) In your experience, is it uncommon to miscarry a normal viable embryo? Is it possibly related to immune as I am tested APS positive though I have already used heparin/immunosuppresents..any tests I should do further? Dr says its not common
4) Or should I go for another round of ivf cycle with PGS
Dear chelseywong,
Do you mean you have already done your 2nd IVF with egg retrieval, in HK?
From your questions 1 and 2, and if I understand correctly, you have 3 frozen embryos from this second IVF and 5 frozen embryos from the first IVF in Taiwan, is that correct?
To answer your questions 1 and 2, you may consider doing PGS on all your embryos in one lot. Since they are all frozen, you can transport the 5 embryos from Taiwan to HK, then request to do PGS on all of them.
For question 3, depending on how the abortus tissues were obtained, it is not uncommon to also contain contamination from maternal source (i.e. your tissues), and therefore, the karyotyping result will be normal (46,XX). There could be other genetic abnormalities of the embryo even though its karyotype was normal, although we cannot rule out your APS from being a cause. So, it is important to know the embryo is a euploid (normal) when it is transferred into your uterus.
Yes, I have 3 remaining frozen embryos left in HK and 5 in Taiwan. Due to clinic restrictions, those embryos cannot be transported back to HK. In this case, do you recommend I do PGS on those 3 embryos first in HK? Will thawing and refreezing the embryos do more harm than good?
Dear chelseywong,
Is it the clinic in Taiwan which does not want to ship, or HK which does not want to receive? Other than these clinics' own policies, it is legally and logistically feasible to ship from Taiwan to HK.
Anyhow, depending on the quality of the 3 embryos in HK, you may choose to do PGS on them first before doing another IVF cycle. Based on published data, embryos that had been frozen-thawed twice but biopsied once, their survival and success rate were similar to those that had been frozen-thawed once; if the embryos had been biopsied twice and frozen-thawed twice, the rates were slightly lower.
Generally speaking, there should be 1 euploid (normal embryo) in every 3-4 blastocysts; the chance of having a euploid often correlates with age. I am not sure if you may consider another IVF cycle to bank more euploids before FET. If so, you can proceed with a new IVF cycle first, and at the same time have the lab to thaw out the 3 frozen embryos so that they can be tested together with the fresh blastocysts from the new cycle.
Hi Cutecutetown,
見左醫生準備放第三次胎 (recap返我係33, 第一次ivf, 16 eggs -> 10 Day 5 + 3 Day 6 Blastocysts -> transferred 2 times -> 1 no implantation + 1 chemical preg). 見醫生時佢strongly against putting 2 embryos as he think i'm young and he said there are complications associated with multiple pregnancy. At the same time, I asked if my third transfer still do not result in a viable pregnancy, is there further tests that can be done (such as PGT).
His opinion is that even if we do PGT for the remaining blastocysts, there is no guarantee that those normal ones will surely implant and the success rate may still be similar to as if we keep transferring the remaining. He said judging from the number of good grade blastocysts that we have, we should just keep transferring... until a viable pregnancy happens.
He mentioned that there are some patients who (and we may also) need to do second or third round ivf (implying that they may have transferred 10 times or more of embryo transfer) before getting a baby home.
The thought of having to transfer 1x times + even need to do a second IVF after all 1x times failure is killing me.
But I know there is no way I can get a second opinion from another doctor, if i still have that many embryos in this specific lab? not that I want to change to another doctor, but this is already bringing me a couple of sleepless nights...
Dear jmbk2,
Just like my answer back in post #5818, you will need to do a third time FET, whether transferring 1 or 2 embryos. Only if you fail again in this 3rd transfer, the doctor will investigate further if the possible cause is your body or the embryos.
You need to DO one thing at a time, not thinking so much ahead because there are simply too many possibilities. Perhaps you will bingo in this 3rd FET, then all your worries will be unnecessary. If you fail and the current doctor still refuses to offer you additional options, seek another doctor. It is also feasible to transport your embryos to another lab.
A positive attitude helps a long way. Good luck on your next FET.
