Hello Dr. Sher,
I am32 years old with an FSH of 5 and an AMH of 13. I’ve had 5 iui’s with clomid/letrozole with one pregnancy from it that ended in a miscarriage. I did not respond very well to clomid so my dr is trying follistim and iui , which they had previously said they would not do injectibles with me unless I was doing Ivf since my amh is so high, but have since decided it would be ok to try. What is the likelyhood that I will overstim or get to many follicles for iui and have to cancel? I have PCOS and hostile cervical fluid (hence the iui’s) my dr will cancel if more than 3 mature follicles.
Side note: we have been to Ivf orientation and have discussed moving to Ivf if this doesn’t work , but I’d rather avoid Ivf if possible.
Unless very carefully applied, there is a significant risk of OHSS as well as high-order multiple pregnancy.There is nothing that can be done to absolutely avoid either from happening.
Geoff Sher
Respected sir,
I am a doctor myself. I practice in Pakistan. My wife has PCOS and Endometriosis. We tried ICSI ,only 3 ovum were retrieved and 2 were fertilized. On day 3rd my embryologist called and said your embryo didn’t cleave so we will have to halt the procedure.
They said Zona pellucida of my wife’s ovum was extra thickened and nucleus was relatively small.
I asked them that in ICSI zona is actually bypassed,so it’s thickness shouldn’t be an issue. But they said it didn’t grow so they need to stop it
Kindly guide me what should I do? I am actually very down. My wife already had a laproscopy and the doctor corrected a blocked tube and took out few cysts and polyps.
Regards
In my opinion, central to success in women with PCOS is the protocol used for ovarian stimulation (see below. As far as the endometriosis, this also introduces additional challenges…such as immunologic implantation dysfunction (IID)….SEE BELOW!!
1. PCOS:
Polycystic ovary syndrome (PCOS) is a common hormonal system disorder among women affecting between 5% and 10% of women of reproductive age worldwide. Women with PCOS may have enlarged ovaries that contain multiple small collections of fluid (subcapsular microcysts) that are arranged like a “string of pearls” immediately below the ovarian surface (capsule).interspersed by an overgrowth of ovarian connective tissue (stroma). The condition is characterized by abnormal ovarian function (irregular or absent periods, abnormal or absent ovulation and infertility, androgenicity (increased body hair or hirsutism, acne) and increased body weight –body mass index or BMI.
Women with PCOS are at increased risk that ovarian stimulation with gonadotropins will result in the, of development of severe ovarian hyperstimulation syndrome (OHSS), a life-endangering condition that is often accompanied by a profound reduction in egg “competency” and on fertilization often yield an inordinately high percentage of “incompetent” embryos which have a reduced potential to propagate viable pregnancies.
Concern and even fear that their PCOS patients will develop of OHSS often leads the treating RE to take measures aimed at reducing the risk of this life-endangering condition. One such measures is to “trigger” egg maturation prematurely in the hope of arresting further follicular growth and the other, is to initiate the “trigger” with a reduced dosage of hCG (i.ed. 5,000U rather than the usual 10,000U of of Pregnyl/Profasi/Novarel, to use or 250mcg rather than 500mcg of Ovidrel or to supplant the hCG “trigger” with a Lupron “trigger” which causes a prompt LH surge from the woman’s pituitary gland to take place. While such measures do indeed reduce the risk of OHSS to the mother, this often comes at the expense of egg quantity and “competency”. Fewer than the anticipated number of eggs are harvested and those that are retrieved are far more likely to be “immature” and chromosomally abnormal (aneuploid”), or “immature” , thereby significantly compromising IVF outcome.
Against this background, It is my considered opinion that when it comes to performing IVF in women with PCOS, the most important consideration must be the selection and proper implementation of an individualized or customized ovarian stimulation protocol. Thereupon, rather than prematurely initiating the “trigger” to arrest further follicle growth, administering a reduced dosage of hCG or “triggering with a GnRH agonist (e.g. Lupron/Buserelin) that can compromise egg “competency”….. use of one of the following techniques will often markedly reduce the risk of OHSS while at the same time protecting egg quality:
1. PROLONGED COASTING…my preferred approach: My preferred approach is to use a long pituitary down-regulation protocol coming off the BCP which during the last 3 days is overlapped with the agonist, Lupron/Buserelin/Superfact. The BCP is intended to lower LH and thereby reduce stromal activation (hyperthecosis) in the hope of controlling LH-induced ovarian androgen (predominantly, testosterone) production and release. I then stimulate my PCOS patients using a low dosage of recombinant FSH-(FSHr) such as Follistim/Gonal-F/Puregon. On the 3rd day of such stimulation a smidgeon of LH/hCG (Luveris/Menopur) is added. Thereupon, starting on day 7 of ovarian stimulation, I perform serial blood estradiol (E2) and ultrasound follicle assessments, watching for the number and size of the follicles and the blood estradiol concentration [E2]. I keep stimulating (regardless of the [E2] until 50% of all follicles reach 14mm. At this point, provided the [E2] reaches at least >2,500pg/ml, I stop the agonist as well as gonadotropin stimulation and track the blood E2 concentration daily. The [E2] will almost invariably increase for a few days. I closely monitor the [E2] as it rises, plateaus and then begins to decline. As soon as the [E2] drops below 2500pg/ml (and not before then), I administer a “trigger” shot of 10,000U Profasi/ Novarel/Pregnyl or 500mcg Ovidrel/Ovitrel. This is followed by an egg retrieval, performed 36 hours later. Fertilization is accomplished using intracytoplasmic sperm injection (ICSI) because “coasted” eggs usually have little or no cumulus oophoris enveloping them and eggs without a cumulus will not readily fertilize naturally. Moreover, they also tend to have a “hardened” envelopment (zona pellucida), making spontaneous fertilization problematic in many cases. All fertilized eggs are cultured to the blastocyst stage (up to day 5- 6 days) and thereupon are either vitrified and preserved for subsequent transfer in later hormone replacement cycles or (up to 2) blastocysts are transferred to the uterus, transvaginally under transabdominal ultrasound guidance. The success of this approach depends on precise timing of the initiation and conclusion of “prolonged coasting”. If started too early, follicle growth will arrest and the cycle will be lost. If commenced too late, too many follicles will be post-mature/cystic (>22mm) and as such will usually harbor abnormal or dysmature eggs. Use of “Coasting” almost always prevents the development of severe OHSS, optimizes egg/embryo quality and avoids unnecessary cycle cancellation. If correctly implemented, the worst you will encounter is moderate OHSS and this too is relatively uncommon.
2. EMBRYO FREEZING AND DEFERMENT OF EMBRYO TRANSFEDR (ET): OHSS is always a self-limiting condition. In the absence of continued exposure to hCG, symptoms and signs as well as the risk of severe complications will ultimately abate. Thus, in the absence of pregnancy, all symptoms, signs and risks associated with OHSS will disappear within about 10-14 days of the hCG trigger. Conversely, since early pregnancy is always accompanied by a rapid and progressive rise in hCG , the severity of OHSS will increase until about the 9th or tenth gestational week whereupon a transition from ovarian to placental hormonal dominance occurs, the severity of OHSS rapidly diminishes and the patient will be out of risk. Accordingly, in cases where in spite of best effort to prevent OHSS, the woman develops symptoms and signs of progressive overstimulation prior to planned ET, all the blastocysts should be vitrified and cryostored for FET in a subsequent hormone replacement cycle. In this way women with OHSS can be spared the risk of the condition spiraling out of control.
2.ENDOMETRIOSIS:
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 blog!
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), iIncreasing 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. 3. EGG-EMBRYO QUALITY: The potential for a woman’s eggs to undergo orderly development and maturation, while in large part being genetically determined can be profoundly influenced by the woman’s age, her “ovarian reserve” and proximity to menopause. It is also influenced by the protocol used for controlled ovarian stimulation (COH) which by fashioning the intra-ovarian hormonal environment, profoundly impacts egg development and maturation. After the menarche (age at which menstruation starts) a monthly process of repeatedly processing eggs continues until the menopause, by which time most eggs will have been used up, and ovulation and menstruation cease. When the number of eggs remaining in the ovaries falls below a certain threshold, ovarian function starts to wane over a 5 to10-years. This time period is referred to as the climacteric. With the onset of the climacteric, blood Follicle Stimulating Hormone (FSH) and later also Luteinizing Hormone (LH) levels begin to rise…. at first slowly and then more rapidly, ultimately culminating in the complete cessation of ovulation and menstruation (i.e. menopause). One of the early indications that the woman has entered the climacteric and that ovarian reserve is diminishing DOR) , is the detection of a basal blood FSH level above 9.0 MIU/ml and/ or an AMH level og <2.0ng/ml. Prior to the changes that immediately precede ovulation, virtually all human eggs have 23 pairs (i.e. 46) of chromosomes. Thirty six to forty hours prior to ovulation, a surge occurs in the release of LH by the pituitary gland. One of the main e purposes of this LH surge is to cause the chromosomes in the egg to divide n half (to 23 in number) in order that once fertilized by a mature sperm ends up having 23 chromosomes) the resulting embryo will be back to having 46 chromosomes. A “competent” mature egg is one that has precisely 23 chromosomes, not any more or any less. It is largely the egg, rather than the sperm that determines the chromosomal integrity of the embryo and only an embryo that has a normal component of 46 chromosomes (i.e. euploid) is “competent” to develop into a healthy baby. If for any reason the final number of chromosomes in the egg is less or more than 23 (aneuploid), it will be incapable of propagating a euploid, “competent” embryo. Thus egg/embryo aneuploidy (“incompetence”) is the leading cause of human reproductive dysfunction which can manifest as: arrested embryo development and/or failed implantation (which often presents as infertility), early miscarriage or chromosomal birth defects (e.g. Down’s syndrome). While most aneuploid (“incompetent”) embryos often fail to produce a pregnancy, some do. However, most such pregnancies miscarry early on. On relatively rare occasions, depending on the chromosome pair involved, aneuploid embryos can develop into chromosomally defective babies (e.g. Down’s syndrome). Up until a woman reaches her mid- thirties, at best, 1:2 of her eggs will likely be chromosomally normal. As she ages beyond her mid-thirties there will be a a progressive decline in egg quality such that by age 40 years only about 15%-20% of eggs are euploid and, by the time the woman reaches her mid-forties, less than 10% of her eggs are likely to be chromosomally normal. While most aneuploid embryos do appear to be microscopically abnormal under the light microscope, this is not invariably so. In fact, many aneuploid embryos a have a perfectly normal appearance under the microscope. This is why it is not possible to reliably differentiate between competent and incompetent embryos on the basis of their microscopic appearance (morphologic grade) alone. The process of natural selection usually precludes most aneuploid embryos from attaching to the uterine lining. Those that do attach usually do so for such only a brief period of time. In such cases the woman often will not even experience a postponement of menstruation. There will be a transient rise in blood hCG levels but in most cases the woman will be unaware of even having conceived (i.e. a “chemical pregnancy”). Alternatively, an aneuploid embryo might attach for a period of a few weeks before being expelled (i.e. a “miscarriage”). Sometimes (fortunately rarely) an aneuploid embryo will develop into a viable baby that is born with a chromosomal birth defect (e.g. Down’s syndrome). The fact that the incidence of embryo aneuploidy invariably increases with advancing age serves to explain why reproductive failure (“infertility”, miscarriages and birth defects), also increases as women get older. It is an over-simplification to represent that diminishing ovarian reserve as evidenced by raised FSH blood levels (and other tests) and reduced response to stimulation with fertility drugs is a direct cause of “poor egg/ embryo quality”. This common misconception stems from the fact that poor embryo quality (“incompetence”) often occurs in women who at the same time, because of the advent of the climacteric also have elevated basal blood FSH/LH levels and reduced AMH. But it is not the elevation in FSH or the low AMH that causes embryo “incompetence”. Rather it is the effect of advancing age (the “biological clock”) resulting a progressive increase in the incidence of egg aneuploidy, which is responsible for declining egg quality. Simply stated, as women get older “wear and tear” on their eggs increases the likelihood of egg and thus embryo aneuploidy. It just so happens that the two precipitating factors often go hand in hand. The importance of the IVF stimulation protocol on egg/embryo quality cannot be overstated. This factor seems often to be overlooked or discounted by those IVF practitioners who use a “one-size-fits-all” approach to ovarian stimulation. My experience is that the use of individualized/customized COS protocols can greatly improve IVF outcome in patients at risk – particularly those with diminished ovarian reserve (“poor responders”) and those who are “high responders” (women with PCOS , those with dysfunctional or absent ovulation, and young women under 25 years of age). While no one can influence underlying genetics or turn back the clock on a woman’s age, any competent IVF specialist should be able to tailor the protocol for COS to meet the individual needs of the patient. During the normal ovulation cycle, ovarian hormonal changes are regulated to avoid irregularities in production and interaction that could adversely influence follicle development and egg quality. As an example, small amounts of androgens (male hormones such as testosterone) that are produced by the ovarian stroma (the tissue surrounding ovarian follicles) during the pre-ovulatory phase of the cycle enhance late follicle development, estrogen production by the granulosa cells (cells that line the inner walls of follicles), and egg maturation. However, over-production of testosterone can adversely influence the same processes. It follows that protocols for controlled ovarian stimulation (COS should be geared toward optimizing follicle growth and development (without placing the woman at risk from overstimulation), while at the same time avoiding excessive ovarian androgen production. Achievement of such objectives requires a very individualized approach to choosing the protocol for COS with fertility drugs as well as the precise timing of the “trigger shot” of hCG. It is important to recognize that the pituitary gonadotropins, LH and FSH, while both playing a pivotal role in follicle development, have different primary sites of action in the ovary. The action of FSH is mainly directed towards the cells lining the inside of the follicle that are responsible for estrogen production. LH, on the other hand, acts primarily on the ovarian stroma to produce male hormones/ androgens (e.g. androstenedione and testosterone). A small amount of testosterone is necessary for optimal estrogen production. Over-production of such androgens can have a deleterious effect on granulosa cell activity, follicle growth/development, egg maturation, fertilization potential and subsequent embryo quality. Furthermore, excessive ovarian androgens can also compromise estrogen-induced endometrial growth and development. In conditions such as polycystic ovarian syndrome (PCOS), which is characterized by increased blood LH levels, there is also increased ovarian androgen production. It is therefore not surprising that “poor egg/embryo quality” is often a feature of this condition. The use of LH-containing preparations such as Menopur further aggravates this effect. Thus we recommend using FSH-dominant products such as Follistim, Puregon, and Gonal-F in such cases. While it would seem prudent to limit LH exposure in all cases of COS, this appears to be more vital in older women, who tend to be more sensitive to LH It is common practice to administer gonadotropin releasing hormone agonists (GnRHa) agonists such as Lupron, and, GnRH-antagonists such as Ganirelix and Orgalutron to prevent the release of LH during COS. GnRH agonists exert their LH-lowering effect over a number of days. They act by causing an initial outpouring followed by a depletion of pituitary gonadotropins. This results in the LH level falling to low concentrations, within 4-7 days, thereby establishing a relatively “LH-free environment”. GnRH Antagonists, on the other hand, act very rapidly (within a few hours) to block pituitary LH release, so as achieve the same effect. Long Agonist (Lupron/Buserelin) Protocols: The most commonly prescribed protocol for Lupron/gonadotropin administration is the so-called “long protocol”. Here, Lupron is given, starting a week or so prior to menstruation. This results in an initial rise in FSH and LH level, which is rapidly followed by a precipitous fall to near zero. It is followed by uterine withdrawal bleeding (menstruation), whereupon gonadotropin treatment is initiated while daily Lupron injections continue, to ensure a “low LH” environment. A modification to the long protocol which I prefer using in cases of DOR, is the Agonist/Antagonist Conversion Protocol (A/ACP) where, upon the onset of a Lupron-induced bleed , this agonist is supplanted by an antagonist (Ganirelix/Cetrotide/Orgalutron) and this is continued until the hCG trigger. In many such cases I supplement with human growth hormone (HGH) to try and further enhance response and egg development. Lupron Flare/Micro-Flare Protocol: Another approach to COS is by way of so-called “(micro) flare protocols”. This involves initiating gonadotropin therapy simultaneous with the administration of GnRH agonist (e.g. Lupron/Buserelin). The intent here is to deliberately allow Lupron to elicit an initial surge (“flare”) in pituitary FSH release in order to augment FSH administration by increased FSH production. Unfortunately, this “spring board effect” represents “a double edged sword” because while it indeed increases the release of FSH, it at the same time causes a surge in LH release. The latter can evoke excessive ovarian stromal androgen production which could potentially compromise egg quality, especially in older women and women with PCOS, whose ovaries have increased sensitivity to LH. I am of the opinion that by evoking an exaggerated ovarian androgen response, such “(micro) flare protocols” can harm egg/embryo quality and reduce IVF success rates, especially in older women, and in women with diminished ovarian reserve. Accordingly, I do not prescribe them at all. Estrogen Priming – My approach for “Poor Responders” Our patients who have demonstrated reduced ovarian response to COS as well as those who by way of significantly raised FSH blood levels are likely to be “poor responders”, are treated using a “modified” long protocol. The approach involves the initial administration of GnRH agonist for a number of days to cause pituitary down-regulation. Upon menstruation and confirmation by ultrasound and measurement of blood estradiol levels that adequate ovarian suppression has been achieved, the dosage of GnRH agonist is drastically lowered and the woman is given twice-weekly injections of estradiol for a period of 8. COS is thereupon initiated using a relatively high dosage of FSH-(Follistim, Bravelle, Puregon or Gonal F) which is continued along with daily administration of GnRH agonist until the “hCG trigger.” By this approach we have been able to significantly improve ovarian response to gonadotropins in many of hitherto “resistant patients”. The “Trigger”: hCG (Profasi/Pregnyl/Novarel) versus Lupron: With ovulation induction using fertility drugs, the administration of 10,000U hCGu (the hCG “trigger”) mimics the LH surge, sending the eggs (which up to that point are immature (M1) and have 46 chromosomes) into maturational division (meiosis) This process is designed to halve the chromosome number , resulting in mature eggs (M2) that will have 23 chromosomes rather that the 46 chromosomes it had prior to the “trigger”. Such a chromosomally normal, M2 egg, upon being fertilized by mature sperm (that following maturational division also has 23 chromosomes) will hopefully propagate embryos that have 46 chromosomes and will be “:competent” to propagate viable pregnancies. The key is to trigger with no less than 10,000U of hCGu (Profasi/Novarel/Pregnyl) and if hCGr (Ovidrel) is used, to make sure that 500mcg (rather than 250mcg) is administered. In my opinion, any lesser dosage will reduce the efficiency of meiosis, and increase the risk of the eggs being chromosomally abnormal. . I also do not use the agonist (Lupron) “trigger”. This approach which is often recommended for women at risk of overstimulation, is intended to reduce the risk of OHSS. The reason for using the Lupron trigger is that by inducing a surge in the release of LH by the pituitary gland it reduces the risk of OHSS. This is true, but this comes at the expense of egg quality because the extent of the induced LH surge varies and if too little LH is released, meiosis can be compromised, thereby increasing the percentage of chromosomally abnormal and of immature (M1) eggs.

Dear Dr Sher,
After repeated unexplained IUI failures and one IVF failure, I went to have IVF treatment to London at a clinic specializing in difficult cases, including autoimmune problems. I have now had IVF treatment with them. Before and after implantation I have been treated for overactive natural killer cells. The treatment included IVIG before and after implantation, dexamethasone and clexane injections. I am now 12 weeks pregnant. My doctor in London wants me to continue having tests for natural killer cells until week 20. However, I actually live in Texas with my husband. I’ve been staying with my parents, who live in England, during this treatment, but I would like to go home to Texas now. Do you know of any clinics in the USA which could continue testing me for natural killer cells until week 20 and provide IVIG treatment if necessary? I will be paying for it privately, so would not need to solve any insurance issues and could go to a different state if necessary.
Thank you for your time.
Best regards,
Elena
Congratulations Elena,
Very Respectfully E…this is my area of special interest and expertise and in my opinion you do not need further IVIG/Intralipid or other immunotherapy for autoimmune implantation dysfunction after the 12th week of pregnancy.
The implantation process begins six or seven days after fertilization of the egg. At this time, specialized embryonic cells (i.e., the trophoblast), which later becomes the placenta; begin growing into the uterine lining. When the trophoblast and the uterine lining meet, they, along with Immune cells in the lining, become involved in a “cross talk” through mutual exchange of hormone-like substances called cytokines. Because of this complex immunologic interplay, the uterus is able to foster the embryo’s successful growth. Thus, from the very earliest stage of implantation the trophoblast establishes a foundation for the future nutritional, hormonal and respiratory interchange between mother and baby. In this manner, the interactive process of implantation is not only central to survival in early pregnancy but also to the quality of life after birth.
Considering its importance, it is not surprising that failure of proper function of this immunologic interaction during implantation has been implicated as a cause of recurrent miscarriage, late pregnancy fetal loss, IVF failure, and infertility. A partial list of immunologic factors that may be involved in these situations includes anti-phospholipid antibodies (APA), antithyroid antibodies (ATA), and most importantly activation of uterine natural killer cells (NKa). Presently, these immunologic markers in the blood can be only adequately measured by a handful of highly specialized reproductive immunology laboratories in the United States. I personally use Reproductive Immunology Associates in Van Nuys, CA or Reprosource in Boston, MA.
The Central role of Natural Killer cells: After ovulation and during early pregnancy, NK cells comprise more than 70% of the immune cell population of the uterine lining. NK cells produce a variety of local hormones known cytokines. Uncontrolled, excessive release of certain cytokines (i.e. TH-1 cytokines) is highly toxic to the trophoblast (“root system”) of the embryo” leading to their programmed death (apoptosis) and, subsequently to failed or compromised/dysfunctional implantation. In the following situations NK cells become activated, and start to produce an excess of TH-1 cytokines:
•Autoimmune Implantation Dysfunction: This is most commonly seen in association with a personal or family history of autoimmune diseases such as ith conditions such as Rheumatoid arthritis, hypothyroidism endometriosis and Lupus Erythematosus, Scleroderma, Dermatomyositis etc. It is also encountered in one third of women who have endometriosis (regardless of its severity), and in cases of “unexplained infertility” as well as with recurrent pregnancy loss (RPL).
•Alloimmune implantation dysfunction where the male and female partners share specific genetic (DQ-alpha and/or HLA) similarities. This is commonly seen in cases of RPL and in cases of secondary infertility
Activated NK cells (NKa) can be detected through the K-562 target cell blood test and (more recently) through uterine biopsy for TH-1 cytokine activity. Treatment involves selective use of Intralipid (IL) or immunoglobulin (IVIG) therapy COMBINED WITH oral steroids, initiated more 10-14 days prior to embryo transfer and in most cases of alloimmune implantation dysfunction, the transfer of a single blastocyst at a time.

Hello Dr. Shre. I received my results back from a PGS testing saying that my only embryo is a low mosaic + 21. Do you think I could still transfer it and what are my chances of having a healthy child. Thank you in advance
Trisomy 21 causes Down syndrome . Yes it is possibly a “mosaic” but if you do the FET, you in my opinion need to commit to doing CVS or amnio if you conceive to rule out and addressx an affected pregnancy.
Good luck!

Hi Dr. Sher,
I would love your opinion on my PGS testing. After 5 egg retrievals I was able to send 3 embryos for testing. One is 46,XY del(7)(q21.11-qter.) I am not sure of the level of abnormality or if it is mosaic. Can you please provide me with any information on this type of issue and the possiblity of a successful transfer and healthy baby.
It could be a mosaic and I personally would do an FET. However, I xcaution that if you conceive, you should do amnio or CVS to confirm normalcy of any pregnancy that might arise so you can address the issue.
