  1. They are rising sluggishly. I am afraid you will need to undergo an US at 6-7 weeks for a definitive answer.

    Good luck!

  2. Dear Dr Sher,

    Thank you for your willingness to share the knowledge and experience with us. I have a few questions

    1. Is poorly layered lining is an issue? I was having trouble for growing lining after priming with BCP due to endometriosis. This cycle, my lining is 8.6 in one dimension and 8.26 mm in other on CD15. On CD12 it was layered, although it was hard to see at my local OB’s office. My ultrasound technician on CD15 said it is poorly layered and slightly ecogenic. Is this a concern in the embryo transfer? I have only 1 PGS normal embryo after multiple retrieval and
    2. Transfer on CD22. Since I did a monitoring on CD15 and my ERA results shows receptivity at 134hrs, I am planning to transfer my embryo on CD22. Is this too late for a medicated cycle?
    3. HCG wash: Do you think there is any benefit for the HCG wash? If yes, when is the ideal time? Intrauterine vs SC?
    4. My FSH = 19 and LH = 18 is relatively high in this transfer cycle, is this a concern? Estrogen around 173 and Progesteron 0.2

    Please advice. Thank you so much

      A: The most important factor is thickness of the lining. Layering/echogenicity is not important.

      It was as far back as 1989, when I first published a study that examined the correlation between the thickness of a woman’s uterine lining (the endometrium), and the subsequent successful implantation of embryos in IVF patients. This study revealed that when the uterine lining measured <8mm in thickness by the day of the “hCG trigger” (in fresh IVF cycles), or at the time of initiating progesterone therapy (in embryo recipient cycles, e.g. frozen embryo transfers-FET, egg donation-IVF etc.) , pregnancy and birth rates were substantially improved. Currently, it is my opinion, that an ideal estrogen-promoted endometrial lining should ideally measure at least 9mm in thickness and that an endometrial lining measuring 8-9mm is “intermediate”. An estrogenic lining of <8mm is in most cases unlikely to yield a viable pregnancy.

      A “poor” uterine lining is usually the result of the innermost layer of endometrium (the basal or germinal endometrium from which endometrium grows) ) not being able to respond to estrogen by propagating an outer, “functional” layer thick enough to support optimal embryo implantation and development of a healthy placenta (placentation). The “functional” layer ultimately comprises 2/3 of the full endometrial thickness and is the layer that sheds with menstruation in the event that no pregnancy occurs.

      The main causes of a “poor” uterine lining are:

      1.Damage to the basal endometrium as a result of:
      a.Inflammation of the endometrium (endometritis) most commonly resulting from infected products left over following abortion, miscarriage or birth
      b.Surgical trauma due to traumatic uterine scraping, (i.e. due to an over-aggressive D & C)
      2.Insensitivity of the basal endometrium to estrogen due to:
      a.Prolonged , over-use/misuse of clomiphene citrate
      b.Prenatal exposure to diethylstilbestrol (DES). This is a drug that was given to pregnant women in the 1960’s to help prevent miscarriage
      3.Over-exposure of the uterine lining to ovarian male hormones (mainly testosterone): Older women, women with diminished ovarian reserve (poor responders) and women with polycystic ovarian syndrome -PCOS tend to have raised LH biological activity.. This causes the connective tissue in the ovary (stroma/theca) to overproduce testosterone. The effect can be further exaggerated when certain methods for ovarian stimulation such as agonist (Lupron/Buserelin) “flare” protocols and high dosages of menotropins such as Menopur are used in such cases.
      4.Reduced blood flow to the basal endometrium:
      Examples include;
      a.Multiple uterine fibroids - especially when these are present under the endometrium (submucosal)
      b.Uterine adenomyosis (excessive, abnormal invasion of the uterine muscle by endometrial glands).

      “The Viagra Connection”

      Eighteen years ago years ago, after reporting on the benefit of vaginal Sildenafil (Viagra) for to women who had implantation dysfunction due to thin endometrial linings I was proud to announce the birth of the world’s first “Viagra baby.” Since the introduction of this form of treatment, thousands of women with thin uterine linings have been reported treated and many have gone on to have babies after repeated prior IVF failure.

      For those of you who aren’t familiar with the use of Viagra in IVF, allow me to provide some context. It was in the 90’s that Sildenafil (brand named Viagra) started gaining popularity as a treatment for erectile dysfunction. The mechanism by which it acted was through increasing penile blood flow through increasing nitric oxide activity. This prompted me to investigate whether Viagra administered vaginally, might similarly improve uterine blood flow and in the process cause more estrogen to be delivered to the basal endometrium and thereby increase endometrial thickening. We found that when Viagra was administered vaginally it did just that! However oral administration was without any significant benefit in this regard. We enlisted the services of a compound pharmacy to produce vaginal Viagra suppositories. Initially, four (4) women with chronic histories of poor endometrial development and failure to conceive following several advanced fertility treatments were evaluated for a period of 4-6 weeks and then underwent IVF with concomitant Viagra therapy. Viagra suppositories were administered four times daily for 8-11 days and were discontinued 5-7 days prior to embryo transfer in all cases.

      Our findings clearly demonstrated that vaginal Viagra produced a rapid and profound improvement in uterine blood flow and that was followed by enhanced endometrial development in all four cases. Three (3) of the four women subsequently conceived. I expanded the trial in 2002 and became the first to report on the administration of vaginal Viagra to 105 women with repeated IVF failure due to persistently thin endometrial linings. All of the women had experienced at least two (2) prior IVF failures attributed to intractably thin uterine linings. About 70% of these women responded to treatment with Viagra suppositories with a marked improvement in endometrial thickness. Forty five percent (45%) achieved live births following a single cycle of IVF treatment with Viagra The miscarriage rate was 9%. None of the women who had failed to show an improvement in endometrial thickness following Viagra treatment achieved viable pregnancies.

      Following vaginal administration, Viagra is rapidly absorbed and quickly reaches the uterine blood system in high concentrations. Thereupon it dilutes out as it is absorbed into the systemic circulation. This probably explains why treatment is virtually devoid of systemic side effects

      It is important to recognize that Viagra will NOT be effective in improving endometrial thickness in all cases. In fact, about 30%-40% of women treated fail to show any improvement. This is because in certain cases of thin uterine linings, the basal endometrium will have been permanently damaged and left unresponsive to estrogen. This happens in cases of severe endometrial damage due mainly to post-pregnancy endometritis (inflammation), chronic granulomatous inflammation due to uterine tuberculosis (hardly ever seen in the United States) and following extensive surgical injury to the basal endometrium (as sometimes occurs following over-zealous D&C’s).

      Combining vaginal Viagra Therapy with oral Terbutaline;
      In my practice I sometimes recommend combining Viagra administration with 5mg of oral terbutaline. The Viagra relaxes the muscle walls of uterine spiral arteries that feed the basal (germinal) layer of the endometrium while Terbutaline, relaxes the uterine muscle through which these spiral arteries pass. The combination of these two medications interacts synergistically to maximally enhance blood flow through the uterus, thereby improving estrogen delivery to the endometrial lining. The only drawback in using Terbutaline is that some women experience agitation, tremors and palpitations. In such cases the terbutaline should be discontinued. Terbutaline should also not be used women who have cardiac disease or in those who have an irregular heartbeat.

      About 75% of women with thin uterine linings see a positive response to treatment within 2-3 days. The ones that do not respond well to this treatment are those who have severely damaged inner (basal/germinal) endometrial linings, such that no improvement in uterine blood flow can coax an improved response. Such cases are most commonly the result of prior pregnancy-related endometrial inflammation (endometritis) that sometimes occurs post abortally or following infected vaginal and/or cesarean delivery.

      Viagra therapy has proven to be a god send to thousands of woman who because of a thin uterine lining would otherwise never have been able to successfully complete the journey “from infertility to family”.

      2. Transfer on CD22. Since I did a monitoring on CD15 and my ERA results shows receptivity at 134hrs, I am planning to transfer my embryo on CD22. Is this too late for a medicated cycle?

      A: I am personally not a believer in ERA. So you need to discuss this with your personal doctor.

      The blastocyst and the endometrium are in a constant state of cross-talk. In order for successful implantation to take place, the blastocyst must be at the appropriate stage of development, and needs to signal a well synchronized endometrium to ‘accept it”. This dialogue between embryo and endometrium involves growth factors, cytokines, immunologic accommodations, cell adhesion molecules, and transcription factors. These are all mostly genetically driven but are also heavily influenced by numerous physiologic, pathophysiologic, hormonal and molecular mechanisms capable of profoundly affecting the receptivity of the secretory endometrium to the overtures made by the embryo, to implant.
      Embryo implantation takes place 6-9 days after ovulation. This period is commonly referred to as the “window of implantation (WOI)”. In the past it was believed that as long as the embryo reached the uterus in this 4 day time frame, its chance of implanting would not be affected.
      In 2013, after evaluating 238 genes in the secretory endometrium and applying bioformatics, Ruiz-Alonzo, et all introduced the Endometrial Receptivity Array (ERA) . Using this test, they categorized mid-secretory endometria into 4 categories: “a) proliferative, b) pre-receptive, c) receptive or d) post-receptive”. They claimed that women with pre-receptive or post-receptive endometria were more likely to experience failed implantation post-embryo transfer (ET).
      It was in large part this research which suggested that the concept of a relatively “wide” (4day) WOI, was flawed, that an optimal WOI is likely much narrower and could be a critical factor in determining the success or failure of implantation post-ET. Ruiz-Alonzo also reported that about 25% of women with recurrent IVF failure (RIF), have pre, or post-receptive endometria. They presented data suggesting that viable IVF pregnancy rates could be enhanced,
      by deferring FET by about 24 hours in women who had pre-receptive endometria and bringing ET forward by the same amount of time, in women with post-receptive endometria,

      There is no doubt that ERA testing has opened the door to an intriguing arena for research. Presently however, available data is inconclusive. Here, following recent studies are 2 dissenting opinions regarding the value for ERA:
      •Basil and Casper (2018) state: “Performing the ERA test in a mock cycle prior to a FET does not seem to improve the ongoing pregnancy rate in good prognosis patients. Further large prospective studies are needed to elucidate the role of ERA testing in both good prognosis patients and in patients with recurrent implantation failure”
      •Churchill and Comstock (2017) conclude:” In our preliminary observations, the non-receptive ERA group had similar live birth rates compared to the receptive ERA group. It appears the majority of the pregnancies conceived in the non-receptive group occurred during ovulatory cycles and thus a non-receptive ERA in a medicated cycle likely does not have prognostic value for ovulatory cycles. Larger studies are needed to assess the prognostic value of ERA testing in the gen-eral infertility population.”
      There are additional negatives that relate to the considerable emotional and financial cost of doing ERA testing:
      1.First, the process costs $600-$1000 to undertake
      2., Second, it requires that the patient undergo egg retrieval, vitrify (cryobank) all blastocysts, res for 1 or more cycles to allow their hormonal equilibrium to restore, do an ERA biopsy to determine the synchronicity of the endometrium, wait a few weeks for the results of the test and thereupon engage in undertaking an additional natural or hormonal preparation cycle for timed FET. This represents a significant time lapse, emotional cost and additional expense.
      Presently, ERA testing is only advocated for women who have experienced several IVF failures. However, some authorities are beginning to advocate that it become routine for women undergoing all IVF.
      The additional financial cost inherent in the performance of the ERA test ($600-$1000), the considerable time delay in getting results, the fact that awaiting results of testing and preparing the patient for FET, of necessity extends the completion of the IVF/ET process by at least a few months, all serve to increase the emotional and financial hardship confronting patients undergoing ERA. Such considerations, coupled with the current absence of conclusive data that confirm efficacy, are arguments against the widespread use of ERA . In my opinion, ERA testing should presently be considered as being one additional diagnostic and be confined to women with “unexplained” RIF.
      Gold standard statistical analyses require that all confounding variables be controlled while examining the effect of altering the one under assessment. There is an obvious interplay of numerous, ever changing variables involved in outcome following ET, e.g. embryo competency, anatomical configuration of the uterus and the contour of the endometrial cavity, endometrial thickness, immunologic and molecular factors as well as the very important effect of technical skill/expertise in performing the ET procedure …(to mention but a few). It follows that it is virtually impossible to draw reliable conclusions from IVF-related randomized controlled studies that use outcome as the end-point. This applies equally to results reported following “ gold standard” testing on the efficacy of ERA and, is one of the main reasons why I question the reliability of reported data (positive or negative).
      The fact is that IVF (and related technologies) constitute neither a “pure science” nor a “pure art”. Rather they represent an “art-science blend”, where scientific principles applied to longitudinal experience and technical expertise coalesce to produce a biomedical product that will invariably differ (to a greater or lesser degree) from one set of clinical circumstances to another.
      Since, the ultimate goal of applied Assisted Reproductive Medicine is to safely achieve the birth of a viable and healthy baby, the tools we apply, that are aimed at achieving this end-point, are honed through the adaptation of scientific principles and concepts, experience and expertise, examined and tested longitudinally over time. Needless to say, the entire IVF/ET process is of necessity subject to change and adaptation as new scientific and technical developments emerge.
      This absolutely applies to the ERA as well!

      3. HCG wash: Do you think there is any benefit for the HCG wash? If yes, when is the ideal time? Intrauterine vs SC?

      A: I am not a believer!

      4. My FSH = 19 and LH = 18 is relatively high in this transfer cycle, is this a concern? Estrogen around 173 and Progesteron 0.2
      A: LH and FSH are not relevant to outcome in FET cycles.

  3. Hi Dr Sher,
    I wrote last week about a bleed during my 6th week of pregnancy after fet. After that bleed I had gone in and a fetal heartbeat was seen and recorded at 111. Today I had another bleed this time bright red and more, I went in for another scan and the heart rate was not easily visible and could not be recorded. Should I be prepared for the worst? My hcg today was 17000. Thank you in advance

    • Take it easy and repeat the US in 1 week. That would be definitive.

  4. Hello Dr. Sher,
    I started estrogen for an FET on Oct 7. After day 14 of estrogen, my endometrial lining is at 7.2 and triple. My RE thinks I’m ready to start progesterone tomorrow (day 15/16) of estrogen. Isn’t the lining too thin? Your website mentions it should be at 9mm, is that before progesterone or at transfer?

    Thank you!

    • In my practice, I do not start progesterone if the lining is <8mm.

  5. Hi Dr. Geoffrey,

    I went in today for my follow up scan from 6 weeks 0 days on 10/13 -where a heart flutter was visualized.
    As of today, embryo grew I believe to 6 plus 2 days and had a HB of 50 BPM. Fertility clinic NP advised me to call ob/gyn and get D & C scheduled. She recommended if we would like to have a baby IVF remains the best bet for us. I am 42 and this is 3rd loss in 3 months. I proceeded with her advice to call OB.

    My OB/GYN called and said he will not do a D & C with a HB and has seen many pregnancies (although this initially looks very grim) go on to have normal pregnancies. He is scheduling and referring me have a higher level ultrasound in 2 days with a perinatologist.

    What is your viewpoint and/or thoughts regarding this bad news?

    • I would give it a week and repeat the US, Kim.

      Good luck and G-d bless!
