  1. Dear Dr. Sher,
    I am taking HRT medications and scheduled for fet in two days. However, yesterday, I had diarrhea and stomach acid attack. I took nexium, maalox and loperamide to address this. In spite of this, I still took my HRT medications ( progynova and duphaston). I am ok now. Do you think it affected the efficacy of my HRT medications? Do I need to take additional HRT meds because of my diarrhea yesterday? Please enlighten me as I am worried since my fet will be in two days from now.

    • No I do not believe there should be a problem. However, discuss with your RE.

  2. Hi Dr. Sher. Are PGS normal day 6 blastocysts even worth transferring in a FET cycle? I have two day 6 and I’m worried about them. Thanks for the time, as always.

    • Absolutely they are worth transferring!

  3. Dear Dr. Sher,

    1) A few days before the start of FSH stimulation, the ultrasound shows that there are four follicles with sizes (13mm, 6.6mm, 3.8mm, 2.9mm) and the estradiol level is at 16.6 pg/mL. Do you think it is advisable to start my IVF cycle with lead follicle already at 13mm at the start of FSH? Will the FSH stimulation days be shortened due to the lead follicle and the remaining three follicles being immature and not able to catch up with the lead follicle?

    2) I am currently taking my Birth Control Pill, 14 pills with lead follicle at 13mm. Should I continue taking the birth control pill for one more week in order that the lead follicle will be released by itself?

    Thanks for your comment and guidance!

    • Hi CR,

      Truthfully, I cannot advise here. You need to discuss this with your personal RE.

  4. I had my son a little over 2.5 years ago. My husband and I conceived him with no trouble. After he was born my cycles came back around 4.5 months and were shorter (25 days) and my menses were much lighter, almost watery at times. I figured it was due to nursing. We have been trying for baby #2 for a year. My cycles have gotten a little heavier but nothing like pre-baby and they for the past five months they fluctuate between 25-29 days (they were consistent 25 days for the two years prior). I went to my doc and had my fsh, thyroid, estrogen, LH checked and it all came back fine. I’ve done home ovulation tests and a few months I never got a positive result, but they were sometimes hard to read. Sorry for the ramble. Any ideas what I should do?

    I was 33 when I had my son and I’m 36 now. Also, I have gained weight so I’m not sure if the combo of those two things are the culprit or if it’s something else.

    Feeling very discouraged.

    • Hi Amie,
      This is secondary infertility and it requires a careful evaluation.

      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.

  5. Hi Doctor, I am in my 2nd pregnancy attempt after first miscarriage in 11-12th week 6 months ago. In my current pregnancy, i am in 7th week per last cycle. Last week (after 45 days) i had the BhCG test done and the result of 658 mIU/ml and i got another blood test done yesterday (after 50 days) and the result is 730mIU/ml. My Gynaecologist told me last week that the hCG level should go up faster and double every two days during this period but I am not able to see this in the result I got today. Doctor also suggested that a lower hCG indicate possibility of weak pregnancy and possible miscarriage.

    • Hi Sammy,

      This does not look good. I think you are heased for a very early loss (chemical pregnancy).

      henever 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).
