Hi Dr Sher. I reconstituted the whole cetrotide (cetrotide 250mcg powder for injection vial with diluent syringe) and only used half of it. You’ve said before it’s ok to use the other half the next day provided it’s refrigerated and used within 24 hours. The piece of paper that comes with the product says it must be used immediately after reconstituting. Do you have your patients discard the rest immediately after reconstitution or do you still allow your patients to refrigerate the remaining 0.125 mcg and re-use 24 hours later? I am not sure what to do and thought to ask you because you routinely prescribe 1/2 dose. Please help!
I advise my patients refrigerate the 2nd half and use it the following day. So far, no problems.

I also forgot to ask, is ANA 1:80 (speckled) a problem? My RE says it’s only an issue it is goes above 1:360. I have been tested for natural killer cells and they were normal. Is there any link between ANA 1:80(speckled) and implantation issues? or are they unrelated? Many thanks.
It is important to note that an ANA of is suggestive of a primary autoimmune state that could be linked to NKa. Please note that it is NOT the concentration of blood NK cells that matters. Rather, it is NK call activation (NKa as measured by the K-562 target cell test by ]endometrial cytokine measurement). These tests can only be conducted in a few Reproductive Immunology Reference Laboratories in the U.S.A.
There is an ever growing realization, recognition and acceptance of the fact that uterine immunologic dysfunction can lead to immunologic implantation dysfunction (IID) with “unexplained infertility”, “unexplained IVF failure” and “recurrent pregnancy loss (RPL)”. Although many factors that contribute to such implantation dysfunction, in the final analysis it is activated “functional” uterine natural killer cells (NKa) in association with cytotoxic-T cells (CTL), which through the production of cytotoxic cytokines (see below) damage the “root system” (trophoblast) of the embryo causing the pregnancy either to be immediately rejected, or so compromising placentation that early pregnancy loss occurs. Both immunoglobulin-G (IVIG) and intralipid (IL) therapy given in combination with corticosteroids (e.g. dexamethasone, prednisone, and prednisolone) are used to effectively reduce/down-regulate activated NK cells.
NK cells” reach the uterus from the woman’s bone marrow, early in the menstrual cycle, as so called “parental” or “progenitor” cells. There these early NK cells proliferate under the effect of estrogens. Only upon being exposed to progesterone do they begin to propagate “functional” NK cells that release cytokines and promote implantation. The concentration of functional NK cells in the endometrium is maximal about 7 days after exposure to natural(endogenous), or synthetic (exogenous) progesterone ….i.e. corresponding to the time the time when the embryo implants into the uterine lining (endometrium).
Functional uterine natural killer (NK) cells as well as T-helper cells are immune cells that frequent the uterine lining. They produce growth factors known as cytokines that regulate orderly implantation of the embryo and facilitate placentation (development of a functional placenta……the baby’s life line).There are of two varieties of uterine cytokines: a) TH-2 (humoral) cytokines that promote permeation of the uterine wall by the embryo’s trophoblast (“root system and, b) TH-1 (cellular) cytokines that oppose trophoblastic proliferation and permeation of the uterine wall by culling interstitial trophoblastic cells. Orderly implantation and formation of a functional placenta (lifeline of the baby) requires that TH-1 and TH2 activity be in equilibrium
There are two categories of immunologic implantation dysfunction (IID) linked to NK cell activation (NKa).
•Autoimmune IID. Here, there is often a personal or family history of autoimmune conditions such as Rheumatoid arthritis, Lupus Erythematosus, and thyroid autoimmune activity (e.g. Hashimoto’s hypothyroidism) etc. Autoimmune IID also occurs in about one third of cases of endometriosis (regardless of its severity).
•Alloimmune IID. Here uterine NK cell activation results from uterine exposure to an embryo derived through fertilization of an egg by a spermatozoon which shares certain genetic (HLA/DQ alpha)characteristics with that of the mother or embryo recipient.
In both autoimmune and alloimmune IID, the end point is excessive NKa/CTL, TH-1 release that damages the embryos trophoblast, resulting in failed implantation or early pregnancy loss.
It is important to bear in mind that measurement of the concentration of blood NK cells has little or no relevance when it comes to assessing NK cell activation (NKa). Rather it is the degree of NK cell activation (cytotoxicity) that matters. In fact there are certain conditions (such as with endometriosis) where the NK cell blood concentrations is normal or well below normal and NK cell activation is markedly increased.
There are several methods by which NK cell activation (cytotoxicity) can be assessed in the laboratory. Methods such as immunohistochemical assessment of uterine NK cells and/or TH-1 and TH-2 cytokines have been used with some success. However, use of the K-562 target cell test remains the gold standard. With this test, NK cells are isolated from the woman’s blood using Flow Cytometry and are incubated in the presence of specific “target cells”. These are then incubated together. The percentage (%) of “target cells” killed through exposure to NKa/CTL-TH1 cytokines is then quantified.
Currently, there are less than a half dozen Reproductive Immunology Reference Laboratories in the U.S.A that are capable of performing the K-562 Target cell test reliably. I have for 20 + years been working with Reproductive Immunology Associates (RIA) in Van Nuys, CA and preferentially recommend them to my patients.
There exist a pervasive but blatant misconception on the part of many, that the addition of IL/IVIG can have an immediate down-regulatory effect on NK cell activity. This has established a demand that Reproductive Immunology Reference Laboratories report on NK cell activity before and following exposure to IVIG and/or IL. However, the fact is that activated “functional” NK cells (NKa) cannot be deactivated in the laboratory. Effective down-regulation of activated NK cells can only be adequately accomplished if their activated “progenitor/parental” NK cells are first down-regulated. Thereupon once these down-regulated “precursor” NK cells are exposed to progesterone, they will begin spawning normal and functional NK cells. This process takes about 10-14 days. It follows that to assess for a therapeutic response to IVIG/IL therapy would require that the patient first be treated (10-14 days prior to embryo transfer) and thereupon, about 2 weeks later, be retested. While at 1st glance this might seem to be a reasonable approach, it is in reality would be of little clinical benefit because even if blood were to be drawn 10 -14 days after IL/IVIG treatment it would require an additional 10 days to receive results from the laboratory and by that time it would be far too late to be of practical advantage.
Neither IVIG nor IL is capable of significantly suppressing already activated “functional NK cells”. For this to happen, the IL/IVIG would have to down-regulate progenitor (parent) NK cell” activity. Thus it should be infused several days prior to ovulation or progesterone administration so that the down-regulated “progenitor/precursor” NK cells” can propagate a sufficient number of normally regulated “functional NK cell” to be present at the implantation site 7 days later.
It is very regrettable that so many patients are being denied the ability to go from “infertility to family” simply because (for whatever reason) so many reproductive specialists refuse to embrace the role of immunologic factors in the genesis of intractable reproductive dysfunction. Hopefully this will change …and the sooner the better.

Hi Dr Sher, I just found out that I have 2 copies of A1298C MTHFR. Is this concerning? What do you normally prescribe for your patients with 2 copies of a1298c? I’ve never achieved a pregnancy and never had a miscarriage. I am told my egg quality is likely poor. I have an AMH of 0.99 (so nearly 1), but I am 40.2 years old. Is clexane routinely used for two copies of a1298c or is clexane not indicated for two copies of a1298C MTHFR?
I would recommend Clexane from the point that the beta hCG becomes +ve and continue until the 6th week of pregnancy. However, at 40Y of age with DOR, I would suggest the following for your consideration:
The older a woman becomes, the more likely it is that her eggs will be chromosomally/genetically “incompetent” (not have the potential upon being fertilized and transferred, to result in a viable pregnancy). That is why, the likelihood of failure to conceive, miscarrying and of giving birth to a chromosomally defective child (e.g. with Down Syndrome) increases with the woman’s advancing age. In addition, as women age beyond 35Y there is commonly a progressive diminution in the number of eggs left in the ovaries, i.e. diminished ovarian reserve (DOR). So it is that older women as well as those who (regardless of age) have DOR have a reduced potential for IVF success. Much of this is due to the fact that such women tend to have increased production of LH biological activity which can result in excessive LH-induced ovarian male hormone (predominantly testosterone) production which in turn can have a deleterious effect on egg/embryo “competency”.
While it is presently not possible by any means, to reverse the age-related effect on the woman’s “biological clock, certain ovarian stimulation regimes, by promoting excessive LH production (e.g. short agonist/Lupron- “flare” protocols, clomiphene and Letrozole), can make matters worse. Similarly, the amount/dosage of certain fertility drugs that contain LH/hCG (e.g. Menopur) can have a negative effect on the development of the eggs of older women and those who have DOR and should be limited.
I try to avoid using such protocols/regimes (especially) in older women and those with DOR, favoring instead the use of the agonist/antagonist conversion protocol (A/ACP), a modified, long pituitary down-regulation regime, augmented by adding supplementary human growth hormone (HGH). I further recommend that such women be offered access to embryo banking of PGS (next generation gene sequencing/NGS)-selected normal blastocysts, the subsequent selective transfer of which by allowing them to to capitalize on whatever residual ovarian reserve and egg quality might still exist and thereby “make hay while the sun still shines” could significantly enhance the opportunity to achieve a viable pregnancy

Dear Dr Sher, I read on this forum that if all goes well, you will consider retiring at the end of 2018. What would we do without you? Will you pass over the reigns to another RE within your clinic and train him/her sufficiently to take over or will you be closing your doors?? Would you consider retiring but staying on as a Consultant RE so that you can still be involved in reviewing cycles for those women considering a cycle with your clinic in 2019? I have seen my fair share of REs over my time, but you seem to be the most knowledgeable and you have an article explaining all the problems I’ve experienced during my failed IVF cycles. I fear that there is no one else that comes close to knowing exactly how the female reproductive system works in combination with IVF as well as you do. Your retirement, whilst I am sure you are very deserving of, will be a significant blow to all women worldwide.. could you please allay the concerns of the concerned woman about your plans for 2019? without your knowledge, women will continue to have failed IVF cycles without your help, especially DOR women..I am convinced that a lot of my failures were due to wrong protocols..
Thank you so kindly for your kind words. This is a very tough decision to reach. In fact, for me it is also very painful…… but there is a time an a season for every living being and I must be realistic. However, I do not intent to just disappear. I hoped to continue to write and advise as long as the need is there.
I truly believe that there is no greater blessing than to be born into a preordained role and thereupon have the good fortune of spending every single working day striving to fulfil that “mission”. But no individual can alone achieve true success. It invariably requires a dedicated team…… And it is to the team of loyal, talented and dedicated, Doctors, Nurses and Embryologists that I have been so fortunate to work with and befriend over the years that all credit must go. It was their selfless contributions, and unwavering loyalty/trust that made the journey so successful and incredibly meaningful

Hi Dr Sher, what would happen if a DOR woman with an AMH of 0.96 did a long down regulation cycle starting on CD21 and dropped the dose of lupron to 5u on day of menstruation and thereafter started stims? I know you favour A/ACP for DOR women, but what are the negative effects of lupron for DOR women if they use 5U lupron when stimulating? Is it too suppressive even with half dose lupron?
That should be OK, except for the possibility that you might respond more slowly than with the A/ACP.
