  1. Dear Dr. Sher,
    I’m currently 37 (38 in 2 months), and have been undergoing fertility treatments for just over a year, TTC for almost 3 years. My doctor believed it was a male factor issue initially: slightly below average samples + varicocele. We tried IUI 3x and none worked. My husband went on Clomid which improved his samples, but we had to do IUI 3x because of Insurance mandate. All failed. Because of the holidays & plans to move onto IVF, we then tried one “last-ditch” timed effort with Clomid (both of us) + trigger: It worked! Sadly I had a missed miscarriage at 7-8 weeks (no heartbeat). The karyotype came back normal/female, but our doctor believed it was inconclusive & that there must’ve been something wrong that was undetected. (I also tested positive for elevated parvovirus antibodies, which was interesting because I did have an odd virus around week 4-5 of pregnancy. Wondering if that could’ve caused the miscarriage? No way to really know, although I’ve never had parvovirus/Fifth’s Disease otherwise to my knowledge.) We finally just tried IVF, antagonist cycle at highest doses, last month. I ended up with 10 follicles, 9 eggs retrieved, 4 fertilized, 3 made it to day 3, 2 blasts at day 5: 4AB, 3CB. We transferred both, but neither implanted. All along throughout IUIs, the pregnancy & this IVF, my uterine lining has been thick (9-11 mm), E2 & progesterone within normal ranges. My AMH is 2.84, my FSH has typically been 7-8 (10 once), and LH also always normal. We are meeting with our doctor this week to get an assessment of why he thinks the IVF failed and what our next steps should be. Insurance will only cover 1 more IVF for us (lifetime), so we’re really anxious to “get it right” next time. I know there are no guarantees, but any advice you can give considering these particulars & what questions I should be asking right now would be so appreciated. Thank you!! SLC

    • I certainly understand your frustration. With normal ovarian reserve (AMH= >2), The ability to generate embryos that are capable of propagating a chromosomally normal conceptus, the ability to propagate a normal uterine lining and numerous failed IUI’s + a failed IVF, this sounds very much like an implantation issue to me.

      Notwithstanding the above, 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. Hi Dr. Sher
    Little background, just turned 42, three Ivf cycles, 4 normal pgs tested embryos from cycle one and two, Just finished 3rd cycle and awaiting testing results. I have fibroids. Pedunculated from post uterine 7x5x5.6 cm, w a 1.7 cm neck. Second is exophytic located right anterior lower uterin 5.3x6x4 cm. left anterior fundal and penduculated 3×3.2×4.8. Had a hysteroscopy last month with normal findings normal contour no impegment. Now the question is should I remove the fibroids before any transfer? If so. How long after surgery can I start FET. At my age I don’t want to Daley getting pregnant as I am hoping for more than one child. Further I have not had any problems with clots or excessive bleeding during my menstural cycle.
    Thank you for your time and advice.

    • I would have the fibroids removed before the FET.

      Fibroids or leiomyomas are non-malignant muscle tumors that grow in the uterine wall. They can be found in about one out of every five (1:5) women >30Y of age. Fibroids are far more prevalent in African Americans and women and less frequent in other ethnic groups (i.e. Caucasians and Asians).
      Fibroids, enlarge and/or distort uterine configuration. They can produce symptoms such as heavy, painful and prolonged menstrual periods. Other symptoms include pain with intercourse, backache, severe abdominal pain when large fibroids run out of blood supply or when superficial fibroids on a stem (pedunculated) undergo twisting (torsion). Sometimes fibroids will protrude into the uterine cavity, cause severe cramping and bleeding and so irritate the uterine lining as to compromise embryo attachment (anatomical implantation dysfunction). Women with fibroids are also at greater risk of miscarriage, premature delivery, malposition of the baby (mandating cesarean delivery) and an increased risk of bleeding after birth (post-partum hemorrhage)
      Diagnosis can be made by one or more of the following symptoms/presentations: Symptomatology, pelvic examination pelvic ultrasound, hysterosalpingogram (HSG), sonohysterogram (HSN), CT-scan or MRI..
      Fibroids are classified as:
      •Submucosal: Here the fibroid grows just under the lining of the uterine cavity (mucosa) or protrudes into the uterine cavity. They might mold into the underlying uterine muscle (sessile) or be on a stalk (pedunculated). Submucosal fibroids can change the shape of the uterine cavity, irritate the lining and prevent implantation, cause miscarriage. These lesions must be removed in their entirety prior to undertaking embryo transfer, usually hysteroscopically. (see below)
      •Subserosal: – Here the tumors grow under the outer layer (serosa) of the uterus. These fibroids will not compromise implantation, but if they are large, causing severe pain, and especially if they are multiple, pedunculated and thus at risk of undergoing torsion (twisting) the3y should be removed, usually laparoscopically. (See below).
      •Intramural: – when the fibroids develop within the muscular wall of the uterus. This is the commonest presentation. Unless they are large and multiple and do not encroach on the uterine cavity, they can be left alone Surgical removal is usually by laparoscopy or laparotomy/abdominal open incision (See below)
      The uterus is composed of a thick layer of smooth muscle (myometrium) surrounding the endometrial lining into which the embryo implants and which serves to protect and nourish a growing pregnancy. These tumors are rarely malignant (see below). Fibroid tumors, even large ones, can occur without producing any symptoms at all.
      For the most part, only those fibroids that impinge upon the uterine (endometrial) cavity (submucosal) affect fertility. Exceptions include large fibroids in the muscle wall of the uterus (intramural) that can block the openings of the fallopian tubes as they enter the uterus, and where multiple fibroids cause abnormal uterine contraction patterns.
      In some cases multiple uterine fibroids may so deprive the uterine lining (endometrium) of blood flow, that the delivery of estrogen to the endometrium is curtailed to the point that the lining cannot thicken sufficient to support a pregnancy. This can result in early 1st trimester (prior to the 13th week of pregnancy) miscarriages. Large or multiple fibroids, by curtailing the ability of the uterus to stretch in order to accommodate the spatial needs of a rapidly growing pregnancy, may precipitate 2nd trimester (beyond the 13th week) miscarriages and/or trigger the onset of premature labor.
      Sizable fibroid tumors are usually easily identified by simple vaginal examination. However, even the smallest fibroid can be identified by transvaginal ultrasound. Sometimes it is difficult to tell if the fibroid is impinging on the uterine cavity. In such cases, a hysteroscopy (where a telescope like instrument, inserted via the vagina into the uterine cavity) or a sonohysterogram where injected fluid, distends the uterine cavity allowing for examination of its inner configuration can help distinguish between intramural and submucosal fibroids. CT scan and MRI can also be used to distinguish between fibroid tumors and another condition that also involves affects the uterine muscular wall, known as adenomyosis. This condition is characterized by endometrial tissue growing deeply into the uterine wall.. Given the often-diffuse nature of adenomyosis, it can be very difficult to remove surgically. This contrasts with fibroid tumors, which are well defined and are usually easily removed.
      Surgical Treatment: The mainstay for the treatment of fibroid tumors is surgical removal (myomectomy). Small, asymptomatic fibroids that do not impinge upon the endometrial cavity will usually not require treatment other than observation and vigilance. Large fibroids and submucosal fibroids should be removed prior to starting fertility treatments such as In Vitro Fertilization (IVF) in order to decrease the chance of implantation failure, miscarriage, pregnancy complications and premature labor. Intramural and subserosal fibroids are readily removable by laparoscopic resection or via an abdominal incision. The former allows for a more rapid convalescence and is ideal for the removal of small and accessible superficial fibroid tumors, while the latter approach is preferred for treating larger and less accessible fibroids.
      Myomectomy can affect fertility in several ways. If the endometrial cavity is entered during the surgery, there is a possibility of post adhesions forming within the uterine cavity. This should always be checked by the performance of a hysteroscopy or through a sonohysterogram, prior to beginning fertility treatment. Because myomectomy can be bloody, there is a high likelihood of post-operative abdominal adhesion formation, which could bind down or encase the ovaries, preventing the release of the eggs, or block the ends of the fallopian tubes. For this reason, it is important that myomectomies be formed only by accomplished surgeons, who are familiar with techniques to limit blood loss and prevent adhesion formation.
      Regardless of whether the laparoscopic or abdominal approach is employed, adequate closure of the uterine wall is essential in order to reduce the subsequent risk of uterine rupture during pregnancy or labor. This is one of the main arguments used against the use of laparoscopic removal of large, multiple or remotely situated fibroids. While laparoscopic myomectomy requires but a few days (at most) for post-operative convalescence, abdominal myomectomy usually requires 6-8 weeks of recovery time. When myomectomy necessitates or results in the uterine cavity being entered (purposefully or inadvertently), it should always be followed up with a “2nd look” hysteroscopy to rule out scar tissue formation, which occurs frequently in the presence of submucosal fibroids.
      Uterine polyps (and in some cases, also submucosal fibroids), can usually be removed hysteroscopically (through the vagina). This eliminates the need for abdominal surgery and greatly reduces the recovery time. Hysteroscopic surgery is only useful if the majority of the fibroid protrudes into the endometrial cavity, ensuring that the tumor defect will not be too large. This surgery is often done under laparoscopic guidance, to reduce the risk of uterine perforation. After hysteroscopic surgery it is often advisable to prescribe cyclical hormonal therapy for a few months to encourage regeneration of the endometrial lining over the area of tumor defect and healing of the uterine muscle. A 2nd look hysteroscopy should be performed a few months later in all cases, to rule out scar tissue formation even if it means delaying or deferring the initiation of definitive fertility treatment.
      Medical Treatment: The growth of fibroid tumors is estrogen-dependent. Thus when a woman enters menopause and stops making female hormones, fibroids tend to shrink in size on their own. Conditions that mimic menopause can also reduce the size of fibroid tumors. The most common of theses treatment is with a medication such as leuprolide acetate (Lupron), which shuts off the communication of the brain with the ovaries, preventing hormone production. However, this type of medication can only be taken for a limited period (usually 6 months) and once the medication is stopped the fibroids will usually regain their original size within a few months. The medication is therefore only a “temporary fix,” used mostly to decrease the size of large fibroids in order to make their ultimate surgical removal easier, or to help a woman bridge the gap until spontaneous menopause sets in. For the majority of women there is no major benefit from Lupron therapy prior to surgery.
      Embolization of Fibroid Tumors: Myomectomy always carries the small (although infrequent) risk that severe, uncontrollable intra-operative bleeding could require the performance of a hysterectomy (complete removal of the uterus) as a life saving measure. Moreover, some women are poor candidates for surgery. This is where a new procedure known as embolization comes in. Embolization is a procedure in which small particles are injected into the arteries of the uterus under radiological guidance to shut off the blood supply to the fibroids, in the hope that they will “shrink” and perhaps, even disappear.
      Embolization is relatively new to the field of gynecology and little is known about its potential effects on future fertility. We are concerned that in the process of shutting off the blood supply to the uterus, it will permanently so reduce endometrial blood flow, as to compromise embryo implantation. For this reason, I do not currently recommend this therapy for women who still wish to conceive and carry a baby in their uterus. At present, it seems best suited for symptomatic women who are finished with their childbearing or who are planning to use a gestational surrogate.

  3. Dear Dr. Sher,
    Why do some Drs recommend Estrogen after IVF transfer and some do not? Does E2 patches help after transfer?

    • Hi Rachael,

      IVF is an art-science blend and belief systems (from experience) play an important role. I use estrogen supplementation selectively.

  4. Dear Dr Sher,
    What causes feeling of heart beat like shock after an embryo transfer? For example feeling a strong heart beat off and on that you can feel near your throat almost or upper chest area like coming out of chest? Could anaesthesia cause it when transfers are done under sedation or could it be that the transfer had an issue?

    • It can be the effect of sedating medications, but in most cases it is apprehension…in my opinion.

  5. Hi Dr. Sher,

    1. We are thinking doing chromosome testing (both). But for my hubby, is it helpful to do a “sperm chromatin structure assay”? I mean, if his chromosome is normal, does it mean his sperm is normal? Does he need both tests done?

    2. Natural Killer Cells testing is for female? so my hubby doesn’t need to do?

    We are travelling to other country, we thought get some tests done since it’s way cheaper in north america.
    Thank you in advance!

    • 1. We are thinking doing chromosome testing (both). But for my hubby, is it helpful to do a “sperm chromatin structure assay”? I mean, if his chromosome is normal, does it mean his sperm is normal? Does he need both tests done?

      A: If there is no overt evidence of male factor (normal sperm parameters), doing the SCSA is in my opinion unnecessary!

      2. Natural Killer Cells testing is for female? so my hubby doesn’t need to do?

      A: Only your immune testing for NK cell activation.

      Good luck!
