Hello Dr Scher, I had a 5 day embryo transfer. My 14 day HCG was 572 and my 16 day was 1074, is this worrisome to you since it has not quite doubled?
Thank you for your time.
I doubt that there is a problem. It is close enough!

Hi Dr. Sher,
I went for my last appointment with my RE yesterday and found out on my ultra sound that my gestational sac is measuring small but the baby is measuring right on time 7 weeks 5 days with a heart beat of 138.
The sac measured 17 mm and the weeks measured 6 wk 4 days.
The CRL is 14mm and the gestational age is 7 wks 5 days.
My RE told me I have a slightly higher chance of miscarriage but not to worry. Should I be worried? I’m finding in my reading that a small gestational sac only happens in 1% of pregnancies and the sac must be at least 5 mm bigger than the baby or the chance for miscarriage is 80%- my gestational sac is only 3 mm bigger.
I don’t know if it matters but it was a pgs tested embryo.
I’m so worried as I have already had 3 miscarriages.
It will probably catch uup. Check in 1 week!

My daughter has gone through 3 cycles of IVF w the assistance of PGD d/t a 25%chance of having a child w nonsyndromic hearing loss Each time she was implanted w perfect blastocyst she became pregnant but lost them all before 6 weeks. The last one really did not implant. She just had surgery for some mild endometriosis and the dr said this should improve her chance of implantation She has two perfect embryo left which will be implanted at end of Jan. Is it true that her early miscarriages could have been caused by her mild endometriosis
Yes it is possible that endometriosis could be causing an immunologic Implantation dysfunction (IID)…see below.
Whenever a patient fails to achieve a viable pregnancy following embryo transfer (ET), the first question asked is why! Was it simply due to, bad luck?, How likely is the failure to recur in future attempts and what can be done differently, to avoid it happening next time?.
It is an indisputable fact that any IVF procedure is at least as likely to fail as it is to succeed. Thus when it comes to outcome, luck is an undeniable factor. Notwithstanding, it is incumbent upon the treating physician to carefully consider and address the causes of IVF failure before proceeding to another attempt:
1.Age: The chance of a woman under 35Y of age having a baby per embryo transfer is about 35-40%. From there it declines progressively to under 5% by the time she reaches her mid-forties. This is largely due to declining chromosomal integrity of the eggs with advancing age…”a wear and tear effect” on eggs that are in the ovaries from birth.
2.Embryo Quality/”competency (capable of propagating a viable pregnancy)”. As stated, the woman’s age plays a big role in determining egg/embryo quality/”competency”. This having been said, aside from age the protocol used for controlled ovarian stimulation (COS) is the next most important factor. It is especially important when it comes to older women, and women with diminished ovarian reserve (DOR) where it becomes essential to be aggressive, and to customize and individualize the ovarian stimulation protocol.
We used to believe that the uterine environment is more beneficial to embryo development than is the incubator/petri dish and that accordingly, the earlier on in development that embryos are transferred to the uterus, the better. To achieve this goal, we used to select embryos for transfer based upon their day two or microscopic appearance (“grade”). But we have since learned that the further an embryo has advanced in its development, the more likely it is to be “competent” and that embryos failing to reach the expanded blastocyst stage within 5-6 days of being fertilized are almost invariably “incompetent” and are unworthy of being transferred. Moreover, the introduction into clinical practice about a decade ago, (by Levent Keskintepe PhD and myself) of Preimplantation Genetic Sampling (PGS), which assesses for the presence of all the embryos chromosomes (complete chromosomal karyotyping), provides another tool by which to select the most “competent” embryos for transfer. This methodology has selective benefit when it comes to older women, women with DOR, cases of unexplained repeated IVF failure and women who experience recurrent pregnancy loss (RPL).
3.The number of the embryos transferred: Most patients believe that the more embryos transferred the greater the chance of success. To some extent this might be true, but if the problem lies with the use of a suboptimal COS protocol, transferring more embryos at a time won’t improve the chance of success. Nor will the transfer of a greater number of embryos solve an underlying embryo implantation dysfunction (anatomical molecular or immunologic).Moreover, the transfer of multiple embryos, should they implant, can and all too often does result in triplets or greater (high order multiples) which increases the incidence of maternal pregnancy-induced complications and of premature delivery with its serious risks to the newborn. It is for this reason that I rarely recommend the transfer of more than 2 embryos at a time and am moving in the direction of advising single embryo transfers …especially when it comes to transferring embryos derived through the fertilization of eggs from young women.
4.Implantation Dysfunction (ID): Implantation dysfunction is a very common (often overlooked) cause of “unexplained” IVF failure. This is especially the case in young ovulating women who have normal ovarian reserve and have fertile partners. Failure to identify, typify, and address such issues is, in my opinion, an unfortunate and relatively common cause of repeated IVF failure in such women. Common sense dictates that if ultrasound guided embryo transfer is performed competently and yet repeated IVF attempts fail to propagate a viable pregnancy, implantation dysfunction must be seriously considered. Yet ID is probably the most overlooked factor. The most common causes of implantation dysfunction are:
a.A“ thin uterine lining”
b.A uterus with surface lesions in the cavity (polyps, fibroids, scar tissue)
c.Immunologic implantation dysfunction (IID)
d.Endocrine/molecular endometrial receptivity issues
Certain causes of infertility are repetitive and thus cannot readily be reversed. Examples include advanced age of the woman; severe male infertility; immunologic infertility associated with alloimmune implantation dysfunction (especially if it is a “complete DQ alpha genetic match between partners plus uterine natural killer cell activation (NKa).
My answer to patients who ask me when is the time to stop undergoing IVF is ….Aside from the weight of the financial burden, the time to stop is when in spite of thorough and comprehensive evaluation, there is no remediable and treatable explanation for repeated failure.

Hi Dr. Sher,
I am doing a natural FET cycle, and on the day of LH surge documented by blood test my lining was only 4.9 mm. If I don’t proceed with the cycle what would you recommend as my next step? Had 2 fresh cycles both of which resulted in pregnancy with a good lining ( one was a miscarriage, d&c and chronic endometritis, Treated with doxy for 7 days. Had a biopsy after that which was normal. Previous medicated FET lining on estrace 3 mg bid intravaginally was at most 6.8 mm, transferred 1 good quality embryo, that cycle did not work.
I am a 39 yo with one child via IVF, have several embryos frozen from 4- 5 months ago. Also when I did my last fresh cycle had 14 or so follicles with lining of 10.2 2 days before retrieval.
Thank you!
A lining of <8mm is fraught with risk of failed implantation. Treatment depends on the cause...see below!

Hi Dr. Sher,
I am a 30 year old healthy female with PCO like ovaries that cause me not to ovulate but no other PCOS like symptoms. I have no other fertility issues and my husband has normal sperm. My husband and I underwent 3 IUIs before moving on to IVF. We completed our IVF retrieval and although did not get pregnant that cycle, it was an overall success where we made a ton of eggs that made it to day 5 and were healthy enough to freeze. We took out all the stops on our 1st retrieval doing ICSI, assisted hatching and PGD testing. We ended up with 17 normal embryos for freezing. We subsequently completed 3 FET with no success at all, never having a positive pregnancy test. For my last cycle, we switched clinics and they put me on daily low dose aspirin, prednisone starting before the transfer, antihistamine protocol (daily Claritin, Pepcid and then Lovenox starting day of transfer). Each transfer we’ve done has been only 1 embryo. We are at a point where we are trying to understand if we just keep trying, maybe with two embryos or consider doing ERA tests (endo receptivity). The ERA tests just require a lot of investment of time given it is a trial and error type test. What recommendations do you think I should take to my RE?
One thing to add – my lining has always been on the very low side, never resulting in a cancelled cycle but it has been as thin as 6.8mm and never above 8mm during all four transfers.
I am not a fan of ERA testing and have not found it to be helpful.
Whenever a patient fails to achieve a viable pregnancy following embryo transfer (ET), the first question asked is why! Was it simply due to, bad luck?, How likely is the failure to recur in future attempts and what can be done differently, to avoid it happening next time?.
