  1. It usually doubles every 48h in the early stage of pregnancy.

  2. Usually every 2 days in the early part of pregnancy. Once the level exceeds 5,000 the rate of rise usually slows down.

  3. Dear Dr.Sher. What chances do we have to get pregnant with bacteriospermia? My husbands numbers are all the time normal in spermiogram, but he always has all these different bacteria found in his semen. Doctors say in IVF it doesnt matter but I am almost sure this is the reason for our infertilityz every year he takes 2-3 months of antobiotics but they won’t go away. Can we get pregnant under these circumstances?
    Thanks in advance!

    • It is important to determine the cause and treat it. It is often due to an organism , Ureaplasma urealyticum which requires special management.

      Ureaplasma urealyticum is a bacterium that belongs to the mycoplasma family. It can be detected in the reproductive tract of as many as 40% of individuals (male and female). Ureaplasma probably does not prevent normal conception in the majority of cases, because the uterine cavity remains sterile even in women whose cervical mucous cultures positive for the organism, however, when present in the woman’s cervical secretions, the organism can be unintentionally dragged into the uterine cavity through introduction of a catheter into the uterus at the time of embryo transfer (ET) or intrauterine insemination (IUI). Molecular biologists have shown that contamination of rapidly growing cell cultures, by this organism and its close “relative”, mycoplasma hominis rapidly destroys such cells. The implanting embryo is indeed an example of an organism that comprises rapidly growing cells in a biological culture medium, (the uterine lining), and as such, the cells of the trophoblast (that form the “root system of the embryo”) are vulnerable to intrauterine infection with Ureaplasma. However, even if the uterine cavity were to become infected with uterine cavity, the infection willl be purged with the shedding of the infected lining at the time of the next menstruation.

      While infection with Ureaplasma rarely produces symptoms in the woman, it sometimes causes symptomatic prostatitis or epydidimitis in men. Although ureaplasma can be transmitted from one partner to the other by sexual intercourse, it may also be acquired by other means, since a large percentage of couples in monogamous relationships will culture positive for the organism. It is very difficult for the organism to grow in the laboratory. Accordingly, the reproductive secretions of both partners should be evaluated (sperm and cervical mucus) individually. Successful culturing of ureaplasma, requires that a specialized media in which the specimens can be transported safely from the physician’s office to the microbiology laboratory. If both partners culture negative, we can assume that there is no infection present. However, if one partner cultures positive and the other negative, we would err on the side of caution, by assuming that the negative result was caused by the difficulty in culturing the organism. When ureaplasma is detected in the reproductive secretions of either partner, both should be treated concurrently, with the appropriate antibiotic, e.g; doxycycline, zithromax, erythromycin, ciprofloxin, or metranidazole).

      Unfortunately, approximately 30-40% of couples infected ureaplasma urealyticum the bacteria will have built resistance to mainstay traditional antibiotics such as tetracyclines (e.g. doxycycline) and erythromycin (e.g. Zythromax) derivatives. In such cases, ciprofloxin or metronidazole (Flagyl) therapy might be needed. This is the reason that we prefer to document cure by reculturing each partner prior to beginning ovarian stimulation for an IVF cycle.

      Several authors have shown a difference in pregnancy rates among patients with ureaplasma infection who were treated with antibiotics and those who were not. Other reports have not been able to identify an effect on outcome from ureaplasma infection. Thus, until the final verdict is in regarding the roll of ureaplasma with regard to its effect on IVF implantation we prefer to be cautious and err on the side of ensuring that this organism is absent in cervical secretions and semen before transferring embryos. To this end my patients all receive prophylactic antibiotic therapy around the time of embryo transfer. This is administered as oral ciprofloxin and a day or two prior to embryo transfer vaginal cleomycin suppositories are added.

  4. Doctor Sher what is the best day to start follistim for an ivf cycle? If you had to pick one day between day 1-5 which would you chose? Has the body already chosen a dominant follicle by cycle day 3 as it would it a normal cycle?

    Then, what is follicular exhaustion? I saw you mention this below. Thank you so much for your time.

    • The earlier the better. I would choose day 2.

  5. Question for Medication cycle for Endometrial receptivity assay.

    Background: I had done ERA twice 1. In Jan 2019, proper medicated cycle Lining 10.4 mm at the time of Biopsy and Progesteron 9.95. In that cycle I didn’t have to take increase lining, i.e. tamoxifen and Endometrial was receptive for transfer at 123 hrs. In my transfer cycle in Feb 2019, I had to take Tamoxifen as the lining was not proportionately increasing. With tamoxifen lining start increasing and it reached 10.4mm and Progesteron 22.1. I transferred exactly after 123 hrs and that PGS normal embryo didn’t implant. So, later on I had laproscopic surgery in March 2019, and they removed Stage II endometriosis. But had some visa issues, so couldn’t transfer sooner. I attempted a transfer cycle in July 2020 and again my lining was not increasing, so they have me take tamoxifen again and my lining was 7.0 mm, Progesteron: 14.5 and I converted to the ERA instead of transferring the embryo and my lining came as pre-receptive. My questions are as follows

    Q.1 Does Tamoxifen known to change the receptivity?
    Q.2 Does thin lining changes the Receptivity?
    Q.3 Does endometriosis surgery also changes the receptivity?
    Q.4 I was also taking 0.5mg of Dexamethasone this cycle as a part of my Immune-protocol, does that change receptivity?

    Please let me know your opinion. I highly value it and appreciate your help.

    • I am not a believer in the value of ERA. In my opinion you likely have an implantation dysfunction which because of associated endometriosis could readily be due to an immunologic implantation dysfunction. This is most likely the scenario with you.

      We should talk!

      When women with infertility due to endometriosis seek treatment, they are all too often advised to first try ovarian stimulation (ovulation Induction) with intrauterine insemination (IUI) ………as if to say that this would be just as likely to result in a baby as would in vitro fertilization (IVF). Nothing could be further from reality It is time to set the record straight. And hence this communication!
      Bear in mind that the cost of treatment comprises both financial and emotional components and that it is the cost of having a baby rather than cost of a procedure. Then consider the fact that regardless of her age or the severity of the condition, women with infertility due to endometriosis are several fold more likely to have a baby per treatment cycle of IVF than with IUI. It follows that there is a distinct advantage in doing IVF first, rather than as a last resort.
      So then, why is it that ovulation induction with or without IUI is routinely offered proposed preferentially to women with mild to moderately severe endometriosis? Could it in part be due to the fact that most practicing doctors do not provide IVF services but are indeed remunerated for ovarian stimulation and IUI services and are thus economically incentivized to offer IUI as a first line approach? Or is because of the often erroneous belief that the use of fertility drugs will in all cases induce the release (ovulation) of multiple eggs at a time and thereby increase the chance of a pregnancy. The truth however is that while normally ovulating women (the majority of women who have mild to moderately severe endometriosis) respond to ovarian stimulation with fertility drugs by forming multiple follicles, they rarely ovulate > 1 (or at most 2) egg at a time. This is because such women usually only develop a single dominant follicle which upon ovulating leaves the others intact. This is the reason why normally ovulating women who undergo ovulation induction usually will not experience improved pregnancy potential, nor will they have a marked increase in multiple pregnancies. Conversely, non-ovulating women (as well as those with dysfunctional ovulation) who undergo ovulation induction, almost always develop multiple large follicles that tend to ovulate in unison. This increases the potential to conceive along with an increased risk multiple pregnancies.

      So let me take a stab at explaining why IVF is more successful than IUI or surgical correction in the treatment of endometriosis-related infertility:
      1.The toxic pelvic factor: Endometriosis is a condition where the lining of the uterus (the endometrium) grows outside the uterus. While this process begins early in the reproductive life of a woman, with notable exceptions, it only becomes manifest in the 2ndhalf of her reproductive life. After some time, these deposits bleed and when the blood absorbs it leaves a visible pigment that can be identified upon surgical exposure of the pelvis. Such endometriotic deposits invariably produce and release toxins” into the pelvic secretions that coat the surface of the membrane (the peritoneum) that envelops all abdominal and pelvic organs, including the uterus, tubes and ovaries. These toxins are referred to as “the peritoneal factor”. Following ovulation, the egg(s) must pass from the ovary (ies), through these toxic secretions to reach the sperm lying in wait in the outer part the fallopian tube (s) tube(s) where, the sperm lie in waiting. In the process of going from the ovary(ies) to the Fallopian tube(s) these eggs become exposed to the “peritoneal toxins” which alter s the envelopment of the egg (i.e. zona pellucida) making it much less receptive to being fertilized by sperm. As a consequence, if they are chromosomally normal such eggs are rendered much less likely to be successfully fertilized. Since almost all women with endometriosis have this problem, it is not difficult to understand why they are far less likely to conceive following ovulation (whether natural or induced through ovulation induction). This “toxic peritoneal factor impacts on eggs that are ovulated whether spontaneously (as in natural cycles) or following the use of fertility drugs and serves to explain why the chance of pregnancy is so significantly reduced in normally ovulating women with endometriosis.
      2.The Immunologic Factor: About one third of women who have endometriosis will also have an immunologic implantation dysfunction (IID) linked to activation of uterine natural killer cells (NKa). This will require selective immunotherapy with Intralipid infusions, and/or heparinoids (e.g. Clexane/Lovenox) that is much more effectively implemented in combination with IVF.
      3.Surgical treatment of mild to moderate endometriosis does not usually improve pregnancy potential:. The reason is that endometriosis can be considered to be a “work in progress”. New lesions are constantly developing. So it is that for every endometriotic seen there are usually many non-pigmented deposits that are in the process of evolving but are not yet visible to the naked eye and such evolving (non-visible) lesions can also release the same “toxins that compromise fertilization. Accordingly, even after surgical removal of all visible lesions the invisible ones continue to release “toxins” and retain the ability to compromise natural fertilization. It also explains why surgery to remove endometriotic deposits in women with mild to moderate endometriosis usually will fail to significantly improve pregnancy generating potential. In contrast, IVF, by removing eggs from the ovaries prior to ovulation, fertilizing these outside of the body and then transferring the resulting embryo(s) to the uterus, bypasses the toxic pelvic environment and is therefore is the treatment of choice in cases of endometriosis-related infertility.
      4.Ovarian Endometriomas: Women, who have advanced endometriosis, often have endometriotic ovarian cysts, known as endometriomas. These cysts contain decomposed menstrual blood that looks like melted chocolate…hence the name “chocolate cysts”. These space occupying lesions can activate ovarian connective tissue (stroma or theca) resulting in an overproduction of male hormones (especially testosterone). An excess of ovarian testosterone can severely compromise follicle and egg development in the affected ovary. Thus there are two reasons for treating endometriomas. The first is to alleviate symptoms and the second is to optimize egg and embryo quality. Conventional treatment of endometriomas involves surgical drainage of the cyst contents with subsequent removal of the cyst wall (usually by laparoscopy), increasing the risk of surgical complications. We recently reported on a new, effective and safe outpatient approach to treating endometriomas in women planning to undergo IVF. We termed the treatment ovarian Sclerotherapy. The process involves; needle aspiration of the “chocolate colored liquid content of the endometriotic cyst, followed by the injection of 5% tetracycline hydrochloride into the cyst cavity. Such treatment will, more than 75% of the time result in disappearance of the lesion within 6-8 weeks. Ovarian sclerotherapy can be performed under local anesthesia or under conscious sedation. It is a safe and effective alternative to surgery for definitive treatment of recurrent ovarian endometriomas in a select group of patients planning to undergo IVF

      I am not suggesting that all women with infertility-related endometriosis should automatically resort to IVF. Quite to the contrary…. In spite of having reduced fertility potential, many women with mild to moderate endometriosis can and do go on to conceive on their own (without treatment). It is just that the chance of this happening is so is much lower than normal.
      IN SUMMARY: For young ovulating women (< 35 years of age ) with endometriosis, who have normal reproductive anatomy and have fertile male partners, expectant treatment is often preferable to IUI or IVF. However, for older women, women who (regardless of their age) have any additional factor (e.g. pelvic adhesions, ovarian endometriomas, male infertility, IID or diminished ovarian reserve-DOR) IVF should be the primary treatment of choice.
