  1. Hi Dr Sher, firstly it is so refreshing to find such an up to date informative blog. I am 38 next month, being trying for 4 years and had 3 failed IVF treatments. I have been diagnosed with unexplained infertility which of course I do not believe to be true. I respond well to pre treatment each time but obviously it then results in a negative. I had seven embryos, all 5 day blastocysts. I will be trying with the fourth in a month or so. I am very lucky to be having IVF on the UK NHS but I feel that they are just not digging deep enough as to why it’s not happening. They have given me no explanations or possible reasons. And certainly no options to try something else. I certainly don’t think I am unexplained. For example, before a period I can spot for up to 9 days. That to me is not normal. on my second attempt my hcg level was 10 which suggested something was trying to happen. I get a lot of pain and discomfort after transfer so I do think something is going on! Do you have any suggestions of what I should be asking the doctors before round four? Should I be pushing for them to investigate further? Thanks so much in advance. Lindsay

    • 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.

  2. Hello Dr. Sher,
    Unfortunately we got a negative result with our IVF fresh transfer last month. Now I am scheduled for a frozen embryo transfer in September. We have 12 frozen embryos that came back normal after PGS testing. My clinic has me scheduled for Neupogen insertion a week before transfer. Can you please tell me a bit about Neupogen and how this may help us? I am 29, PCOS type ovaries and adenomyosis, never been pregnant. Also we need to decide between transferring one or two embryos. I had very high quality hatched blastocysts, we really hoped the single embryo transfer would work last month. Hoping to do everything we can to be successful this time. Thank you for your advice.

    • Sorry! I do not believe in or use Neupogen insertions.

  3. Dear Doctor Sher,

    Thanks for working on the blog to answer my questions. My husband and I have been trying for a baby for almost 4 years. I was diagnosed as Diminishing Ovarian Reserve three years ago when my AMH was less than 0.16 and FSH 10.2. After that I have been seeing local fertility clinics and had Clomid Challenge test with FSH going up to 24. In the recent 1 year, I had 3 failed medicated IUI, with both letrozole and follistim usage in the last treatment, but only 2 leading follicles were produced. I was pregnant eight years ago and experienced a chemical pregnancy last November, a natural one between treatments. After that, I had HSG test done. Both the uterus and tubes look fine. The results of antiphoseholipid antibodies test show that 2 of them were on borderline and 10 negative. I have also been monitoring my basic body temperature for over a year. Mildly elevated temperature was seen in most of the cycles, which I think hints a normal ovulation.
    Currently I am seriously considering IVF to be my next step, but the local doctor says my body is not responsive to medication and the success rate would be only 1% at my age of 37. So I want to see your opinions on my case and if possible a couple of questions to be answered.
    1. What protocols do you think would be available in my case? (super low AMH, age of 37, maybe not responsive to medication?) What success rate do you estimate?
    2. I have heard of mini-IVF which might work better for DOR patients older than 35. What’s your opinion about it? If cost is not considered, do you think it would work better in my case?
    3. Will your clinic take patients similar to my case? I am living in Seattle. So if I am going to your clinic, how can we operate the process? how often do we need to fly to Vegas?
    Thanks again for your time and your help with my questions.

    Best,
    Kate

    • Hi Kate,

      In spite of your age being 37Y, the extent of your diminished ovarian reserve make it unlikely that IVF using your own eggs is the answer. You really need IVF with egg donation.

      If that is absolutely out of the question for you, then in my opinion,you would be best served using a modified, long pituitary down-regulation protocol (the agonist/antagonist conversion protocol-A/ACP) augmented by adding supplementary human growth hormone (HGH). I further recommend Staggered IVF with embryo banking of PGS (next generation gene sequencing/NGS)-normal blastocysts in such cases. This type of approach will in my opinion, optimize the chance of a viable pregnancy per embryo transfer procedure and provide an opportunity to capitalize on whatever residual ovarian reserve and egg quality still exists, allowing the chance to “make hay while the sun still shines”.

  4. taking letrizole. I plan on traveling out of town so will not be able to go in for a day 12 us. Will I ovulate without the trigger shot? Should I take the trigger when / if I get a + ovulation test or just skip it this month?

    • Mimi,

      This is definitely something you need to discuss and resolve with your own treating doctor. I cannot interject here.

      Sorry!

  5. Hello,
    I am 34 years old and have a son (3 years old) and daughter (21 months). Got pregnant with both on first try. Got pregnant a third time (11/2015) the first time as well. Carried baby for 12 weeks and ended up in miscarriage. I had a D&C last January and have been trying to get pregnant ever since. After 5 months of trying I started seeing a fertility specialist last month. We did all the tests….bloodwork, ultrasounds, ink test. sperm, bloodwork at start of period. Everything came back perfect. Just did an IUI a week ago. I’ve been trying to find success rates for unexplained secondary fertility and have not seen anything. Especially for people who had no problem getting pregnant 3 times. What do you think mu success rate is given my history. Doctor thinks it’s a matter of timing but who knows.

    • It is one thing for a woman who has never been able to conceive (primary infertility) to come to grips with undergoing In Vitro Fertilization. It is quite another matter for someone who has successfully achieved a pregnancy in the past having to come to terms with a subsequent inability to conceive (secondary infertility). When this happens, it raises issues of guilt, a declining sense of self-worth and ultimately self-recrimination. The ramifications often impact family relationships involving partners and siblings. The truth is that secondary infertility can be just as difficult for individuals and family to deal with as primary infertility.
      There are many factors that contribute to the problem of secondary infertility. These include:
      Social and marital factors: In this modern day and age where at least one in two marriages ends in divorce, it is not surprising that there would be an inevitable hiatus in childbearing. This often results in a considerable delay in re-initiating family building. Since the biological clock keeps on ticking in the interim, advancing age can, and often does, have a profound affect on a woman’s ability to subsequently conceive and successfully complete a pregnancy. In my experience, this is one of the most common reasons for secondary infertility. In addition, by the time a decision is made to enter a new relationship, many men and women will have undergone a prior sterilization procedure which now needs to be addressed. To make matters worse, many such men and women first opt for surgical reversal of their occlusive surgery, only to learn in the end that the procedures were not successful, and they now need to consider in vitro fertilization (IVF) in one form or another.
      Financial factors: Here, the cost of raising a child often weighs heavily, especially in this present tough economic climate. This is becoming more of an issue as women playing an ever increasing role as a primary bread winner.
      Career demands: There can be little doubt that when it comes to climbing the career ladder, women are considerably disadvantaged by the fact that pregnancy and the immediate demands of child rearing take away from their ability to compete with men. As such, many women choose to delay having another child until such time as they have been able to make up for prior lost opportunity.
      Medical barriers to fertility: Certain common medical conditions, while not absolutely precluding pregnancy, make it much more difficult to conceive.
      Endometriosis: It is not uncommon for women with endometriosis to achieve a pregnancy, but find difficulty in doing so again at a later date. The reason for this is that while most women with endometriosis have patent fallopian tubes, the environment surrounding their tubes is compromised due to pelvic toxins that are produced by the endometriotic implants. These toxins compromise egg fertilization potential, making it more difficult for sperm in the fallopian tube to fertilize the egg upon its arrival there. As such, endometriosis is one of the commonest causes of secondary infertility.
      Tubal damage due to prior pelvic inflammatory disease: In first world countries, the early and often indiscriminate use of antibiotics for the slightest symptom has led to the point where an acute attack of pelvic inflammatory disease is often masked. As such, less than 30% of American women with tubal damage have knowledge that their tubes are compromised and that they might have subsequent difficulty in conceiving. Since, in many such cases the tubal damage will not have totally blocked both tubes, some of the women so affected might experience a pregnancy but have difficulty in conceiving again later down the line.
      Dysfunctional ovulation: Since ovulation as well as normal hormonal support of the early implanting embryo are both essential for a healthy pregnancy to occur, it follows that women with irregular or dysfunctional ovulation (e.g., polycystic ovarian syndrome – PCOS, persistent follicular luteal phase deficiencies or post birth control pill ovulatory problems) might sporadically conceive and thereupon find it difficult to do achieve another pregnancy later on.
      Immunologic Implantation Dysfunction (IID): has become ever more apparent that immunologic factors play an important role in achieving healthy implantation. Women with endometriosis (regardless of its severity), those with a personal or family history of autoimmune diseases such as lupus erythematosus, rheumatoid arthritis and thyroid autoimmunity (TAI), and some cases where the man and the woman share certain genetic similarities (alloimmune implantation dysfunction), will have activated CTL/NK cells that can inhibit or compromise healthy implantation. This is an often overlooked cause of secondary infertility. Most such autoimmune/alloimmune cases require selective immunotherapy and IVF.
      Antisperm Antibodies: Although infrequent, some cases of secondary infertility might also be caused by the woman harboring antisperm antibodies. In such cases IVF is mandated.
      Previous post-pregnancy uterine infection: Retention of products of conception after the birth of a child, miscarriage, or abortion can so damage the uterine lining as to result in subsequent implantation failure. Unless specifically looked for, this will usually be unknown to the patient, who will simply present with secondary infertility. Treatment is often difficult because such patients might not respond adequately to surgical removal of intrauterine scar tissue or to hormonal or Viagra therapy
      Male immunologic factors: Most men who have undergone a previous vasectomy more than 10 years earlier, will have antisperm antibodies that will interfere with fertilization. Such cases require IVF with intracytoplasmic sperm injection (ICSI). Here we offer a few words of caution to men who are considering undergoing surgical reversal of vasectomy. Always first have a test done to exclude the presence of circulating antisperm antibodies, because in such cases, even if the reversal is successfully performed, they will not be able to initiate a pregnancy without IVF/ICSI.
      Whatever the cause, secondary infertility often affects older couples disproportionately, creating a sense of urgency and even desperation in achieving a viable pregnancy before time runs out. It is for this reason that IVF becomes the treatment of choice in such cases. However, even IVF becomes progressively less successful with advancing age of the woman (whose eggs are being fertilized). In such cases it is important for the couple to be realistic with regard to their expectations. Here, options that include embryo banking and egg donation should be carefully considered.
      Another important point is that whenever a regularly ovulating younger woman (under 36 years of age) with patent fallopian tubes is diagnosed with secondary infertility, it is essential to consider underlying endometriosis or non-obstructive tubal disease as a possible cause. In such cases, IVF is again the treatment of choice.

      I hope this helps!
