  1. Hi Dr Sher, what is the difference between a saline sonogram and a hysteroscopy?

    • The former is a simple in-office procedure where a salt solution is injected via the cervix into the uterine cavity and thereupon an ultrasound examination displays the outline and regularity of the cavity. An hysteroscopy involves introducing a thin telescope like instrument via the vagina and cervix , into the uterine cavity to explore its contour. It is usually done under conscious sedation.

  2. Dear Dr Sher,

    I had a modified natural cycle FET (letrozol 5mg+ gonal f 75iu) and my lining grew to 9mm on the day of trigger. (Estrogen level: 3750). 5 days after trigger my blood levels were as follows: Progesterone: 190+ , estrogen: 1.700. On the day of transfer my lining shrunk to 6mm. Is this ok? Why did you think this happened and how can it be prevented?

    Ps: medicated cycles do not work for me as my lining does not get thick enough.

    • Hard to comment authoritativelywithout much more information.

      Sorry!

  3. Dear Dr. Sher
    I am 42 years old, have a 2.t years old son.
    Since then early RPL. 5 mc in 16 months.
    First fell at week 8 and the resr chemicals. On the last pregnancy I took prednison once I got positive beta and beta climbed nicely until stopped at blight ovlioum.
    On this last pregnancy I used my frozen eggs preserved at age 36 for social reasons.
    Managed to get tested for HLA-C, dq alpha match and nk cell activity etc.
    Got partial dq alpha match and 100% Hla-c match in allel Hla-c*12. My husbsnd is homozygot and I am hetero. As expected eleveted nk etc.
    We also took GC route, I wonder whether this hla-c match is an issue? Does it require special GC testing? I want to try to concieve naturally after some further embreyo banking. Do I need neupogen or any additional treatment on top of ivig or lit?
    I deeply appreciate your time and good advices. Thank you, Irit

  4. Hi Dr Sher, I had a polyp removed in 2016. Would this have been done via a hysteroscopy? Am I correct in thiking that if there were any issues it would have been flagged at the time? Is there any reason to do a repeat hysteroscopy?

    • Yes! However, 2016 was too long ago. You need another evaluation of your uterine cavity by hysteroscopy or sonohysterogram before undergoing another ET.

      Good luck!

  5. Hi Dr Sher, to clarify my earlier question about what your thoughts are on the endo immune biopsy.
    My NKC tests shows CD3 and CD19 to be high. My doctor said I will need steroids and intralipids in an FET.

    Another doctor had previously suggested doing the endo immune biopsy. Do you still think it is useful to do it if I am already going to be on intralipids? What is the prescription if issues are found? TIA!

    • Very respectfully,

      In my opinion, elevated CD3 and CD19 is alone not an indication for Intralipid/steroid therapy. Please see below:

      Central to making a diagnosis of an immunologic implantation dysfunction (IID) is a need for the appropriate interpretation of Natural Killer Cell Activity (NKa). In this regard, one of the commonest and most serious errors, is interpret the blood concentration of natural killer cells as being relevant. Rather it is the activity (toxicity) of NK cells that matters as mentioned. This activity can best be measured using the blood, K-562 target cell test (the gold standard). and/ or endometrial biopsy for cytokine activity.
      With the K-562 test, the most important consideration is the percentage of target cells “killed” in the “native state”. In most cases a level of >10% killing should be regarded with suspicion and >12% overtly abnormal. In addition to reporting the result of the K-562 test, in the “native state” (without adding, Immunoglobulin-G (IVIG) or Intralipid (IL) which many Laboratories erroneously do to try and determine whether either or both of these immune therapies would have a therapeutic benefit or is/are unlikely to be of clinical value. The entire premise upon which this assertion is based, is in my opinion flawed. Clinically such NK cell deactivation can only be significantly affected in vivo as it takes more than a week following infusion to occur. Thus, what happens to the percentage of target cells killed with the K-562 test, by adding IVIG or IL is in my opinion irrelevant
      Another way to assess endometrial NKa is by measuring TH-1 and TH-2 cytokines in endometrial tissue derived through biopsy.TH-1 cytokines kill the trophoblast (the root system of the embryo). Thus if is an excess of TH-1 cytokine activity is found with/without a disruption in the TH-1: TH-2 ratio, this points to NK cell activation.
      There are basically two causes of immunologic implantation dysfunction (IID), a) Autoimmune (85%) & , b) Alloimmune (15%). The former occurs when the body reacts to its own tissue and the latter (far less common) when the male and female partners share certain genotypic similarities involving DQ alpha and HLA genes. In both cases IID results in rejection of the pregnancy due to uterine Natural Killer (NK) Cell and T-cell activation leading to the release of an excessive amount of TH-1 cytokines. These, “toxins” attack the embryo’s root system (trophoblast), killing the cells and causing implantation to fail.
      Autoimmune Implantation Dysfunction: Autoimmune implantation dysfunction, most commonly presents with presumed “infertility” due to such early pregnancy losses that the woman did not even know she was pregnant in the first place. Sometimes there as an early miscarriage. Tests required are: a) blood levels of all IgA, IgG and IgM-related antiphospholipid antibodies (APA’s) directed against six or seven specific phospholipids, b) both antithyroid antibodies (antithyroid and antimicrosomal antibodies), c) a comprehensive reproductive immunophenotype (RIP) and, c) most importantly, assessment of Natural Killer (NK) cell activity (rather than concentration) by measuring by their killing, using the K-562 target cell test and/or endometrial cytokine activity tests.
      It is important to recognize that currently there are only about 3 or 4 Reproductive Immunology Reference Laboratories in the U.S.A that, are capable of reliably analyzing the required elements with a sufficient degree of sensitivity and specificity. I use a Reprosource, a laboratory located in Boston,MA.
      Patients with Alloimmune implantation Dysfunction usually present with a history of unexplained (usually repeated) miscarriages or secondary infertility (where the woman conceived initially and thereupon was either unable to conceive again or started having repeated early miscarriages. However, it can also present as “presumed” primary infertility. Alloimmune dysfunction is diagnosed by testing the blood of both the male and female partners for matching DQ alpha genes and NK/CTL activation. It is important to note that any DQ alpha match (partial or complete) will only result in an IID when there both a DQa/HLA match exists along with NK cell activation. With the exception of cases where both partners have a total (absolute DQa match and treatment requires the use of sperm from a non-matching sperm donor, about 90% of cases alloimmune implantation will have a partial match where 1: 2 embryos will match the woman’s DQa genotype and half will not. In cases of an alloimmune dysfunction (with associated NKa), treatment with IL or IVIG will in my opinion, will not protect against a matching embryo being rejected. It can only clear the NK environment for an embryo that does not match the woman’s DQa genotype. For this reason, it is my opinion that only 1 embryo should be transferred at a time because, given the fact that i:2 embryos will match, transferring >1 embryo at a time creates a risk that the matching embryo will evoke a local NKa/’cytokine response that will “muddy the water” for both. Thus, in cases of a “partial” DQa match I recommend against transferring more than a single embryo at a time.
