  1. Evening Dr Sher,
    I am residing in Australia and have a question regarding Viagra use for endometrial thickness. I conceived after my first ovulation induction cycle with Letrozole, pregnyl trigger and pregnyl luteal support. Lining pre ovulation 9.5mm. Unfortunately this resulted in a partial molar pregnancy. I had 2 D&C’s to resolve this. I had one period after this and then went back on the pill as I also have endometriosis and was symptomatic with pain and headaches. I was on the pill for 5 months and then stopped and started my next ovulation induction cycle with the withdrawal bleed. Good cycle in terms of follicle and hormone levels but lining only reached 7.5 mm . My period was light and now I’m Day 12 of my next cycle with a 14mm follicle (usually ovulate on day 17- 21) but lining is 5mm. My specialist has started me on Viagra today ( Day 12).
    1. Do you think the Viagra will help even though I’m starting late in the cycle?
    2. Do you think my thinner lining is associated with going onto the OCP almost straight after D+C and not having time to re-establish my lining before starting treatment again? Or do you think this could be damage as a result of 2 D&C’s

    • 1. Do you think the Viagra will help even though I’m starting late in the cycle?

      A: No doubt, the earlier you start, the better.

      2. Do you think my thinner lining is associated with going onto the OCP almost straight after D+C and not having time to re-establish my lining before starting treatment again? Or do you think this could be damage as a result of 2 D&C’s

      A: I doubt it has anything to do with OC. The D&C’s might have contributed.

      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. Hello doctor, I just had an embryo transfer yesterday, we were doing a natural frozen embryo transfer. They drew blood yesterday and called with results today saying my progesterone is perfect but my estrogen dropped from last weeks 250 to a very low number and they need to put me on oral tablets and patches. Are my chances of this embryo transfer working completely gone now? I have been crying all day. This is my fourth transfer…

    • It does not necessarily spell disaster. However, you willneed to be tough and hang in and wait for the test results when due!

      Good luck!

  3. Hi Dr. Sher,
    I had immunology test after one FET failure.
    Anti nuclear Antibodies is positive & there is NK cell deficiency.
    Is it treatable within 6 months?
    Thanks in advance.

    • If there is no increased NK cell activation the rest is not really relevant to reproductive potential.However, make certain that they tested NK cell activation and NOT concentration in the blood!

      Unless tests for immunologic implantation dysfunction (IID) are performed correctly and conducted by a one of the few reliable reproductive immunology reference laboratory in the United States, treatment will likely be unsuccessful. . In this regard it is most important that the right tests be ordered and that these be performed by a competent laboratory. There are in my opinion only a handful of reliable Reproductive Immunology Laboratories in the world and most are in the U.S.A. Also, it is my opinion that far too often, testing is inappropriate with the many redundant and incorrect tests being requested from and conducted by suboptimal laboratories. Finally for treatment to have the best chance of being successful, it is vital that the underlying type of IID (autoimmune IID versus alloimmune) be identified correctly and that the type, dosage, concentration and timing of treatments be carefully devised and implemented. I recommend that my patients be tested by ReproSource Reproductive Immunology Reference Laboratory, Boston, MA.
      WHO SHOULD UNDERGO IID TESTING?
      When it comes to who should be evaluated, the following conditions should in always raise a suspicion of an underlying IID, and trigger prompt testing:
      •A diagnosis of endometriosis or the existence of symptoms suggestive of endometriosis (heavy/painful menstruation and pain with ovulation or with deep penetration during intercourse) I would however emphasize that a definitive diagnosis of endometriosis requires visualization of the lesions at laparoscopy or laparotomy)
      •A personal or family history of autoimmune disease such as hyper/hypothyroidism (as those with elevated or depressed TSH blood levels, regardless of thyroid hormonal dysfunction), Lupus erythematosus, Rheumatoid arthritis, dermatomyositis, scleroderma etc.)
      •“Unexplained” infertility
      •Recurrent pregnancy loss (RPL)
      •A history of having miscarried a conceptus that, upon testing of products of conception, was found to have a normal numerical chromosomal configuration (euploid).
      •Unexplained IVF failure
      • “Unexplained” intrauterine growth retardation due to placental insufficiency or late pregnancy loss of a chromosomally normal baby
      What Parameters should be tested?
      In my opinion, too many Reproductive Immunologists unnecessarily unload a barrage of costly IID tests on unsuspecting patients. In most cases the initial test should be for NK cell activation, and only if this is positive, is it necessary to expand the testing.
      The parameters that require measurement include:
      oFor 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 uterine cytokine measurement. As far as the ideal environment for performing such tests, it is important to recognize that currently there are only about 5 or 6, Reproductive Immunology Reference Laboratories in the U.S capable of reliably analyzing the required elements with a sufficient degree of sensitivity and specificity (in my opinion).
      oFor Alloimmune implantation Dysfunction: While alloimmune Implantation usually presents with a history of unexplained (usually repeated) miscarriages or secondary infertility (where the woman conceived initially and thereupon was either unable to conceive started having repeated miscarriages 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 IID when there is concomitant NK/CTL activation (see elsewhere on this blog).

      How should results be interpreted?
      Central to making a diagnosis of an immunologic implantation dysfunction is the appropriate interpretation of natural killer cell activity (NKa) .In this regard, one of the commonest and most serious errors, is to regard the blood concentration of natural killer cells as being significant. Rather it is the activity (toxicity) of NK cells that matters as mentioned. Then there is the interpretation of reported results. 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 my opinion, trying to interpret the effect of adding IVIG or Intralipid to the sample in order assess whether and to what degree the use of these products would have a therapeutic benefit is seriously flawed and of little benefit. Clinically relevant NK cell deactivation can only be significantly effected in vivo and takes more than a week following infusion to occur. Thus what happens in the laboratory by adding these products to the sample prior to K-562 target cell testing is in my opinion likely irrelevant.
      There exists a pervasive but blatant misconception on the part of many, that the addition of Intralipid (IL) /immunoglobulin-G 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, which 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, in reality it 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, by which 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 10-14 several 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. In addition, to be effective, IL/IVIG therapy needs to be combined with steroid (dexamethasone/prednisone/prednisolone) therapy to down-regulates (often) concomitantly activated T-cells.

  4. Dear Dr. Sher,

    I went in today for baseline testing for a FET. I have two cysts, one of which is a hemorrhagic cyst that was discovered in July during my mock cycle. The sizes are 21mm and 14mm. Is it safe to proceed with the FET? The literature seems to say that my chances would be lowered. But my clinic says it’s fine to proceed. Thoughts?

    • I agree with your clinic!

      Geoff Sher

  5. Dear Doctor Sher

    I have done 4 IVF cycles and ovulated before they could surgically remove the eggs two times. All four cycles have been on the protocol where you start with birth control and then cross with lupron the last few days, then lower the dose of lupron by 5 units and then stay on that dose until trigger. The only difference between the two times I ovulated and the two times I didn’t, was the times I did ovulate, my RE instructed me to take the FSH 200 unites and menopur 75 units the same day as trigger. Do you think the dose of FSH before trigger caused this, because it’s the only difference .

    Is it possible for the lupron to mask the rise of LH & progesterone? In both cycles where I ovulated my bloodwork showed no rise either hormone.

    Thank you .

    • I think it was a matter of timing of the hCG trigger and length of time between trigger and proposed ER. I do not think it had to do with taking gonadotropins on the day of the “trigger”.
