Hi Doctor
I am 34 and TTC. I have PCOS and very irregular cycles that have ranged from 26 to 40 days in the last year. Took the pill for 5 days that helps you ovulate (forgot the name). Cycle day 1 was Sept, 15 2020. I was advised to make sure to have intercourse every other day from Sept 24 (cycle day 10) to Oct 4th (cycle day 20) and we did. Ultrasound on Sept 29th (cycle day 15) said I was going to ovulate. October 6th ultrasound said I ovulated. But when exactly is unknown.
I started to feel crampy, bloated, and gassy a week ago. I also think I am hungrier than usual and am using the washroom more. I usually never get cramps before a period. Only on the first day of flow.
I did a blood test Oct 15th and it was negative, results <1. My progesterone level was 28. I thought progesterone was supposed drop after ovulation? Should my progesterone levels be that high on cycle day 31?
Oct 16th, light spotting today and still having cramps. Usually day 1 of my period is the heaviest and I can't recall that spotting is a part of that.
Could I have tested too early for HCG to show up in my blood? Could I have ovulated on Oct 4th and it's just too early to tell? (Wishful thinking probably). Or could it be that the ovulation pills have raised my progesterone?
Your comments will be greatly appreciated!
Please read on PCOS, below!
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 small collections of fluid — called follicles — located in each ovary as seen during an ultrasound. 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. The ovaries of women with PCOS characteristically contain multiple micro-cysts often arranged like a “string of pearls” immediately below the ovarian surface (capsule).interspersed by an overgrowth of ovarian connective tissue (stroma).
PCOS is one of the most common causes of menstrual irregularities, infertility, and hirsutism, Despite an enormous effort to define its cause, the etiology of PCOS remains unclear, and there is no definite cure at this time. PCOS is clearly a heterogeneous disorder which often has a familial (genetic) basis. Infertility associated with PCOS has been attributed to numerous factors, including dysfunctional gonadotropin pituitary secretion, peripheral insulin resistance, elevated adrenal and/or ovarian androgen (male hormone) levels, and dysfunction of several growth factors. Women with this condition are often obese and insulin resistant. The compensatory hyperinsulinemia further stimulates ovarian androgen production which may be detrimental to egg maturation and there is a clear link between the degree of insulin resistance and anovulation. PCOS is also a significant long-term health risk for women, thus necessitating vigilance through regular annual examinations (non-insulin dependent diabetes mellitus, hypertension, hypercholesterolemia, cardiovascular disease and endometrial cancer). Whereas PCOS-related infertility is usually manageable through the use of fertility drugs, lifestyle changes (diet and exercise) remain a mainstay of long-term therapy. More recently, ovulation rates, circulating androgens, pregnancy rates and perhaps even first-trimester miscarriage rates have been shown to improve when insulin sensitizers like metformin are used to correct the underlying insulin resistance.
Most patients with PCOS are young and have excellent pregnancy rates with oral clomiphene. Those that require more aggressive treatments with injectable medications probably represent a subgroup of PCOS patients with severe ovarian dysfunction. These women often have explosive response to gonadotropins which can result in serious complications like Severe Ovarian Hyperstimulation Syndrome (OHSS…see below) and high order multiple births. In those women, the ability to perform “prolonged coasting” (see below) and selectively transfer fewer embryos during IVF offers a clear advantage over standard gonadotropin injections.
Egg quality in PCOS
The potential for a woman’s eggs to undergo orderly maturation, successful fertilization and subsequent progression to “good quality embryos” is in large part genetically determined. However, the expression of such potential is profoundly susceptible to numerous influences, especially intra-ovarian hormonal changes during the pre-ovulatory phase of the cycle. Proper follicular stimulation as well as precise timing of egg maturation with LH (Luteinizing Hormone) or hCG (human chorionic gonadotropin) is crucial to optimal egg maturation, fertilization and ultimately embryo quality. Both pituitary gonadotropins, LH and FSH (follicle stimulating hormone) play a pivotal but different role in follicular development. The action of FSH is mainly directed toward granulosa cell (cells lining the inside of the follicle) proliferation and estrogen production (E2). LH, on the other hand, acts primarily on the ovarian stroma (the connective tissue that surrounds the follicle) to produce androgens. While small amounts of ovarian androgens, such as testosterone, enhance egg and follicle development, over-exposure to them can have a deleterious effect. Furthermore, excessive ovarian androgens can also compromise estrogen-induced endometrial growth and development.
Suppressing pituitary secretion of LH with gonadotropin releasing hormone (GnRH) agonists such as Lupron®, is particularly useful in PCOS. In that condition, serum LH levels are elevated, leading to stromal overgrowth, follicular arrests (so-called cysts) and high levels of androgens synthesis. It is therefore not surprising that these follicles often yield poorly developed (“immature”) eggs” at the time of egg retrieval (ET) and that “poor egg/embryo quality”, inadequate endometrial development and high miscarriage rates are common features of this condition. However, contrary to popular belief, this is not due to an intrinsic deficit in “egg quality”. Stimulation protocols geared toward optimizing follicle and egg development and avoiding over exposure to androgens correct these problems ad result in pregnancy rates similar to those of non-PCOS women. Whereas the overuse of LH-containing preparations such as Menopur® and Luveris® further aggravates this effect. In conclusion, to maximize ultimate oocyte maturation, we strongly recommend against the exclusive use of such products in PCOS patients, preferring FSH-dominant products such as Folistim®, Gonal F® or Bravelle® over a period of at least 9 days following pituitary suppression with Lupron®.
PCOS women often have a family history of diabetes and demonstrable insulin resistance (evidenced by high blood insulin levels and an abnormal 2-hour glucose tolerance test).This underlying Diabetes mellitus tendency could play a role in the development of PCOS and contribute to the development of obesity, an abnormal blood lipid profile, and a predisposition to coronary vascular disease. Women with PCOS are slightly more at risk of developing uterine, ovarian and possibly also breast cancer in later life and accordingly should be evaluated for these conditions on a more frequent basis than would ordinarily be recommended to non-PCOS women.
Most women with PCOS either do not ovulate at all or they ovulate irregularly. As a consequence thereof they in addition usually experience delayed, absent or irregular menstruation. In addition, an inordinate percentage of the eggs produced by PCOS women following ovulation induction, tend to be chromosomally abnormal (aneuploid). Rather than being due to an intrinsic egg defect being inherent in PCOS women, the poor egg quality more than likely the result of over-exposure to male hormones (predominantly, testosterone) produced by the ovarian stroma. These two factors (ovulation dysfunction and poor egg quality) are the main reasons for the poor reproductive performance (infertility and an increased miscarriage rate) in PCOS women.
PCOS patients are at an inordinate risk of severely over-responding fertility drugs, both oral varieties (e.g. Clomiphene, Serophene & Femara) and especially the injectables (e.g. Follistim, Puregon, Gonal F, Menopur and Bravelle) by forming large numbers ovarian follicles. This can lead to life endangering complications associated with sever ovarian hyperstimulation (OHSS). In addition PCOS women receiving fertility drugs often experience multiple ovulations putting them at severe risk (40%+) of high order multiple pregnancy (i.e. triplets or greater) with often devastating consequences.
VARIETIES OF POLYCYSTIC OVARIAN SYNDROME:
1) Hypothalamic-pituitary-PCOS: This is the commonest form of PCOS and is often genetically transmitted and is characteristically associated with a blood concentration of Luteinizing Hormone (LH) that is uncharacteristically much higher than the Follicle Stimulating Hormone (FSH) level (FSH is normally higher than the LH concentration) as well as high-normal or blood androgen ( male) hormone concentrations (e.g. androstenedione, testosterone and dehydroepiandrosterone -DHEA).Hypothalamic-pituitary-ovarian PCOS is also often associated with insulin resistance and in about 40%-50% of the cases.
2) Adrenal PCOS: Here the excess of male hormones are derived from overactive adrenal glands rather than from the ovaries. Blood levels of testosterone and/or androstenedione raised but here, but here, the blood level of dehydroepiandrosterone (DHEAS) is also raised, clinching the diagnosis.
3) Severe pelvic adhesive disease secondary to severe endometriosis, chronic pelvic inflammatory disease and/or extensive pelvic surgery: Women who have this type of PCOS tend to less likely to hyperstimulate in response to ovulation induction . Their. DHEAS is also is not raised.
TREATMENT OF INFERTILITY DUE TO ASSOCIATED OVULATION DYSFUNCTION:
Hypothalamic-pituitary-/ovarian PCOS: Ovulation induction with fertility drugs such as clomiphene citrate, Letrozole (Femara) or gonadotropins, with or without intrauterine insemination (IUI) is often highly successful in establishing pregnancies in PCOS women. However, IVF is fast becoming a treatment of choice (see below).
In about 40% of cases, 3-6 months of oral Metformin (Glucophage) treatment results in a significant reduction of insulin resistance, lowering of blood androgen levels, an improvement in ovulatory function, and/or some amelioration of androgenous symptoms and signs.
Surgical treatment by “ovarian drilling” of the many small ovarian cysts lying immediately below the envelopment (capsule) of the ovaries, is often used, but is less successful than alternative non-surgical treatment and is only temporarily effective. The older form of surgical treatment, using ovarian wedge resection is rarely used any longer as it can produce severe pelvic adhesion formation.
Adrenal PCOS is treated with steroids such as prednisone or dexamethasone which over a period of several weeks will suppress adrenal androgen production, allowing regular ovulation to take place spontaneously. This is often combined with clomiphene, Letrozole and/or gonadotropin therapy to initiate ovulation.
PCOS attributable to Pelvic Adhesive Disease is one variety which often is associated with compromised ovarian reserve, a raised FSH blood level and ovarian resistance to fertility drugs. In many such cases, high dosage of gonadotropins (FSH-dominant) with “estrogen priming” will often elicit an ovarian response necessary for successful ovulation induction and/or IVF. Neither steroids nor Metformin are helpful in the vast majority of such cases.
PCOS women undergoing ovulation induction usually release multiple eggs following the hCG trigger and are thus at inordinate risk of twin or higher order multiple pregnancies. They are also at risk of developing OHSS. Many now believe that IVF should be regarded as a primary and preferential treatment for PCOS. The reason is that it is only through this approach that the number of embryos reaching the uterus can be controlled and in this manner the risk of high-order multiples can be minimized and it is only in the course of IVF treatment that a novel treatment method known as “prolonged coasting” ( see below) which prevents OHSS, can be implemented
SEVERE OVARIAN HYPERSTIMULATION SYNDROME (OHSS):
As indicated above, there is an inordinate propensity for women with PCOS to hyper-respond to gonadotropin fertility drugs and in the process produce large numbers of ovarian follicles. If left unchecked this can lead to OHSS, a potentially life endangering condition. The onset of OHSS is signaled by the development of a large number of ovarian follicles (usually more than 25 in number). This is accompanied by rapidly rising plasma estradiol (E2) levels, often exceeding 3000pg/ml within 7 or 9 days of stimulation, often rapidly peaking above 6,000 pg/ml prior to hCG administration. When this happens, the risk of OHSS developing is above 80%.
Symptoms and signs of OHSS include: abdominal distention due to fluid collection (ascites), fluid in the chest cavity (hydrothorax), rapid weight gain (of a pound or more per day) due to tissue fluid retention, abdominal pain, lower back ache, nausea, diarrhea, vomiting, visual disturbances such as blurred vision and spots in front of the eyes (scotomata), a rapidly declining urine output, cardiovascular collapse and failure of blood to clot which sometimes results in severe bruising (echymosis) and frank bleeding. These symptoms and signs may appear before pregnancy can be diagnosed. If pregnancy occurs, the condition is likely to worsen progressively over a period of 3-5 weeks whereupon it rapidly resolves spontaneously over a few days. If no pregnancy occurs, the symptoms and signs all disappear spontaneously within 10-12 days of the hCG injection.
When increasing fluid collection in the abdominal cavity (ascites) starts to compromise breathing raising the head of the bed rose slightly by placing a 4-6 inch block at the base of each head post and using a few additional pillows, will sometimes help ameliorate the problem. In cases where this does not help or symptoms become severe, all or most of the fluid can readily and safely be drained through t transvaginal sterile needle aspiration (vaginal paracentesis-performed once or sometimes twice a week) can be performed once or twice weekly . The problem will usually self corrects within 10-12 days of the hCG shot if pregnancy does not occur or, by the 8th week of pregnancy.
Urine output should be monitored daily to see if it drops below about 500ml a day (about two cups and a half). A chest X-ray, to evaluate for fluid collection in the chest and around the heart should be done weekly along with blood tests for hematocrit, BUN, electrolytes, creatinine, platelet count and fibrin split products (FSP). If indicated on the basis of a deteriorating clinical situation, hospitalization might be needed for close observation and if necessary, to provide intensive care.
In all case of OHSS, the ovaries will invariably be considerably enlarged. This is irrelevant to the final outcome, unless ovarian torsion (twisting of the ovary on its axis), an extremely rare complication occurs. The latter would usually require surgical emergency surgical intervention.
It is important to know that symptoms and signs of OHSS are severely aggravated by rising hCG levels. Thus such patients should not receive additional hCG injections.
Does PCOS cause poor egg/embryo quality? It is an undeniable fact that women with PCOS undergoing IVF are commonly found to have poorly developed (“dysmorphic”) eggs, with reduced fertilization potential and yielding “poor quality embryos”. However, in the author’s opinion (which admittedly runs contrary to popular opinion), this is unlikely to be due to an intrinsic deficit in egg quality. Rather, it more likely relates to intra-ovarian hormonal changes brought about by hyperstimulation and which compromise egg development. This effect, in the author’s opinion, can often be significantly reduced through implementation of an individualized or customized ovarian stimulation protocols that minimize exposure of the developing follicles and eggs to excessive LH-induced ovarian androgens. This can be best achieved by limiting the use of LH-containing gonadotropins such as Menopur through selective institution of “prolonged coasting” (see below).
In the past, the onset of OHSS, heralded by the presence of large numbers of developing ovarian follicles and rapidly rising plasma estradiol levels often led the treating physician to prematurely administer hCG in an attempt to abruptly arrest the process and prevent escalation of risk to the patient. However the premature administration of hCG, while abruptly arresting further proliferation of estrogen producing granulosa cells in the follicles, unfortunately also prematurely arrests egg development. Since the ability of an egg to achieve optimal maturation upon hCG triggering is largely predicated upon it having achieved prior optimal development, the untimely administration of hCG which triggers meiosis, probably increases the risk of numerical chromosomal abnormalities (aneuploidy) of the egg. This in turn would lead to reduced fertilization potential, poor egg/embryo quality and low embryo implantation potential.
In women with PCOS the connective tissue that surrounding the follicles (ovarian stroma) is often characteristically overgrown (stromal hyperplasia). It is the stroma that produces androgens (mainly testosterone) in response to LH. It is this, coupled with the fact that PCOS women also often have elevated blood LH concentrations (see above) results in the excessive production of androgen hormones, which is so characteristic in PCOS. While excessive exposure of developing eggs to ovarian androgens compromises follicle and egg growth it also impairs endometrial response to estrogen, which could explain the common finding of poor endometrial thickening in many PCOS women undergoing IVF.
The obvious remedy for these adverse effects on egg and endometrial development is to employ stimulation protocols that limit ovarian over-exposure to LH and allowing the time necessary for the follicles/eggs to develop optimally, prior to administering hCG through the judicious implementation of “Prolonged coasting” (PC).
“PROLONGED COASTING”:
In the early 90’s we were the first to report on “prolonged coasting” (PC), a novel approach that protects egg quality while preventing the development of OHSS. PC has since, gained widespread acceptance as a method of choice for preventing OHSS and has established itself as the “standard of care”. It involves withholding gonadotropin therapy while continuing the administration of the GnRHa and waiting until the plasma estradiol concentration drops below 2,500 pg/ml. Thereupon hCG is administered. In such cases, regardless of the number of developed follicles or the number of eggs retrieved, these women rarely, if ever develop OHSS. It has been reported that while PC virtually eliminates the risk of life-endangering complications associated with OHSS, there are reports in the literature that “the price to pay with PC” is often a poorer fertilization rate and reduced embryo implantation potential, compromising the pregnancy”. It is the author’s opinion an experience in the development of PC that egg/embryo quality deficit likely has little to do with the process of PC, itself and can be explained as follows: When PC is initiated too early, follicle growth and development may cease (as evidenced by the estradiol level plateauing or falling immediately, rather than showing an initial continued increase), and when PC is started too late, the follicles will often become cystic, measuring >21mm by the time the estradiol level falls below the safe threshold of 2500pg/ml, and so harbor dysmorphic eggs. Thus precise timing of the initiation of PC is critical. It should in pact be initiated preemptively in all cases when there are more than 25 follicles and the plasma estradiol reaches or exceeds 2,500pg/ml in association, provided that at least 50% of the follicles measuring 14-16mm in mean diameter. Not a day sooner or a day later. If PC is initiated with precise timing, it will usually be followed by a further progressive rise in the estradiol concentration. After a few days, the estradiol level will plateau and then it will start to fall (often rapidly). The temptation to trigger with hCG before the estradiol level falls below 3000picogtrams per milliliter must be resisted …even if the level falls below 1,000pg/ml by the time hCG is given.
Since when using agonist ( Cetrotide/Ganirelix/Orgalutron) pituitary suppression throughout the stimulation phase with gonadotropins, the plasma estradiol level often under expressed follicle growth, this method of pituitary blockade should not be used in cases ( such as with PCOS) where PC might be required.

Hello,
I suffered a miscarriage in June at 5.5 weeks so I’m nervous now being pregnant again. At what I think was 16dpo based on OPK, my HCG was 440 and progesterone 32. However, at 18dpo HCG didn’t double in 48 hours, it only went up to 789. Please share your insights.
It was a little short of doubling in 48h, but close enough for me to be guardedly optimistic for you. Repeat in 2 days and do an US in 2 weeks to get a definitive answer.
Good luck!
Geoff Sher
Hello Dr Sher,
I hope you’re well. I’ve been directed to your website by a friend and am so glad I have found it. Thank you for all your work.
My latest embryo transfer has just resulted in a negative pregnancy test. Over the last 18 months I have had, all with day 5 blastocysts:
1: fresh transfer – chemical
2: frozen – chemical
3: frozen – chemical
4: frozen – negative
5: frozen – cancelled (2 remaining embryos did not survive thaw)
6: fresh – negative
I was diagnosed with raised natural killer cells (with a blood test) in December, and consequently had intralipids with my last transfer. I have recently had an appointment with a miscarriage specialist who is sending me off for tests for autoimmune and histamine issues – I have an underactive thyroid (although we don’t believe it is Hashimotos as my antibodies seem normal), hyperflexible elbows and Raynaud’s disease. My AMH (6.9 pmol/l) is fairly low for my age (34), although I respond well to ovarian stimulation. We have had a lot of other tests – karyotyping, DNA fragmentation, MTHFR, thrombophilia, ERA, HSG… All were normal, except the ERA which showed I was pre-receptive, so I need another day of progesterone support before a FET. The latest miscarriage specialist is also recommending a hysteroscopy.
We now have three chromosomally normal embryos in the freezer.
I guess my question for you is – does this seem like a case of autoimmune implantation dysfunction to you? Our next plan is to use IVIg with my next transfer, would you recommend steroids as well?
Huge thanks and best wishes,
Alex
It does all sound like an implantation issue. I would definitely not proceed to FET until the reason for your recurrent pregnancy loss (RPL) has been identified and a rational strategy to address this, is defined….see below!
When it comes to reproduction, humans are the poorest performers of all mammals. In fact we are so inefficient that up to 75% of fertilized eggs do not produce live births, and up to 30% of pregnancies end up being lost within 10 weeks of conception (in the first trimester). RPL is defined as two (2) or more failed pregnancies. Less than 5% of women will experience two (2) consecutive miscarriages, and only 1% experience three or more.
Pregnancy loss can be classified by the stage of pregnancy when the loss occurs:
•Early pregnancy loss (first trimester)
•Late pregnancy loss (after the first trimester)
•Occult “hidden” and not clinically recognized, (chemical) pregnancy loss (occurs prior to ultrasound confirmation of pregnancy)
•Early pregnancy losses usually occur sporadically (are not repetitive).
In more than 70% of cases the loss is due to embryo aneuploidy (where there are more or less than the normal quota of 46 chromosomes). Conversely, repeated losses (RPL), with isolated exceptions where the cause is structural (e.g., unbalanced translocations), are seldom attributable to numerical chromosomal abnormalities (aneuploidy). In fact, the vast majority of cases of RPL are attributable to non-chromosomal causes such as anatomical uterine abnormalities or Immunologic Implantation Dysfunction (IID).
Since most sporadic early pregnancy losses are induced by chromosomal factors and thus are non-repetitive, having had a single miscarriage the likelihood of a second one occurring is no greater than average. However, once having had two losses the chance of a third one occurring is double (35-40%) and after having had three losses the chance of a fourth miscarriage increases to about 60%. The reason for this is that the more miscarriages a woman has, the greater is the likelihood of this being due to a non-chromosomal (repetitive) cause such as IID. It follows that if numerical chromosomal analysis (karyotyping) of embryonic/fetal products derived from a miscarriage tests karyotypically normal, then by a process of elimination, there would be a strong likelihood of a miscarriage repeating in subsequent pregnancies and one would not have to wait for the disaster to recur before taking action. This is precisely why we strongly advocate that all miscarriage specimens be karyotyped.
There is however one caveat to be taken into consideration. That is that the laboratory performing the karyotyping might unwittingly be testing the mother’s cells rather than that of the conceptus. That is why it is not possible to confidently exclude aneuploidy in cases where karyotyping of products suggests a “chromosomally normal” (euploid) female.
Late pregnancy losses (occurring after completion of the 1st trimester/12th week) occur far less frequently (1%) than early pregnancy losses. They are most commonly due to anatomical abnormalities of the uterus and/or cervix. Weakness of the neck of the cervix rendering it able to act as an effective valve that retains the pregnancy (i.e., cervical incompetence) is in fact one of the commonest causes of late pregnancy loss. So also are developmental (congenital) abnormalities of the uterus (e.g., a uterine septum) and uterine fibroid tumors. In some cases intrauterine growth retardation, premature separation of the placenta (placental abruption), premature rupture of the membranes and premature labor can also causes of late pregnancy loss.
Much progress has been made in understanding the mechanisms involved in RPL. There are two broad categories:
1.Problems involving the uterine environment in which a normal embryo is prohibited from properly implanting and developing. Possible causes include:
•Inadequate thickening of the uterine lining
•Irregularity in the contour of the uterine cavity (polyps, fibroid tumors in the uterine wall, intra-uterine scarring and adenomyosis)
•Hormonal imbalances (progesterone deficiency or luteal phase defects). This most commonly results in occult RPL.
•Deficient blood flow to the uterine lining (thin uterine lining).
•Immunologic implantation dysfunction (IID). A major cause of RPL. Plays a role in 75% of cases where chromosomally normal preimplantation embryos fail to implant.
•Interference of blood supply to the developing conceptus can occur due to a hereditary clotting disorder known as Thrombophilia.
2.Genetic and/or structural chromosomal abnormality of the embryo.Genetic abnormalities are rare causes of RPL. Structural chromosomal abnormalities are slightly more common but are also occur infrequently (1%). These are referred to as unbalanced translocation and they result from part of one chromosome detaching and then fusing with another chromosome. Additionally, a number of studies suggest the existence of paternal (sperm derived) effect on human embryo quality and pregnancy outcome that are not reflected as a chromosomal abnormality. Damaged sperm DNA can have a negative impact on fetal development and present clinically as occult or early clinical miscarriage. The Sperm Chromatin Structure Assay (SCSA) which measures the same endpoints are newer and possibly improved methods for evaluating.
IMMUNOLOGIC IMPLANTATION DYSFUNCTION
Autoimmune IID: Here an immunologic reaction is produced by the individual to his/her body’s own cellular components. The most common antibodies that form in such situations are APA and antithyroid antibodies (ATA).
But it is only when specialized immune cells in the uterine lining, known as cytotoxic lymphocytes (CTL) and natural killer (NK) cells, become activated and start to release an excessive/disproportionate amount of TH-1 cytokines that attack the root system of the embryo, that implantation potential is jeopardized. Diagnosis of such activation requires highly specialized blood test for cytokine activity that can only be performed by a handful of reproductive immunology reference laboratories in the United States.
Alloimmune IID, i.e., where antibodies are formed against antigens derived from another member of the same species, is believed to be a relatively common immunologic cause of recurrent pregnancy loss.
Autoimmune IID is often genetically transmitted. Thus it should not be surprising to learn that it is more likely to exist in women who have a family (or personal) history of primary autoimmune diseases such as lupus erythematosus (LE), scleroderma or autoimmune hypothyroidism (Hashimoto’s disease), autoimmune hyperthyroidism (Grave’s disease), rheumatoid arthritis, etc. Reactionary (secondary) autoimmunity can occur in conjunction with any medical condition associated with widespread tissue damage. One such gynecologic condition is endometriosis. Since autoimmune IID is usually associated with activated NK and T-cells from the outset, it usually results in such very early destruction of the embryo’s root system that the patient does not even recognize that she is pregnant. Accordingly the condition usually presents as “unexplained infertility” or “unexplained IVF failure” rather than as a miscarriage.
Alloimmune IID, on the other hand, usually starts off presenting as unexplained miscarriages (often manifesting as RPL). Over time as NK/T cell activation builds and eventually becomes permanently established the patient often goes from RPL to “infertility” due to failed implantation. RPL is more commonly the consequence of alloimmune rather than autoimmune implantation dysfunction.
However, regardless, of whether miscarriage is due to autoimmune or alloimmune implantation dysfunction the final blow to the pregnancy is the result of activated NK cells and CTL in the uterine lining that damage the developing embryo’s “root system” (trophoblast) so that it can no longer sustain the growing conceptus. This having been said, it is important to note that autoimmune IID is readily amenable to reversal through timely, appropriately administered, selective immunotherapy, and alloimmune IID is not. It is much more difficult to treat successfully, even with the use of immunotherapy. In fact, in some cases the only solution will be to revert to selective immunotherapy plus using donor sperm (provided there is no “match” between the donor’s DQa profile and that of the female recipient) or alternatively to resort to gestational surrogacy.
DIAGNOSING THE CAUSE OF RPL
In the past, women who miscarried were not evaluated thoroughly until they had lost several pregnancies in a row. This was because sporadic miscarriages are most commonly the result of embryo numerical chromosomal irregularities (aneuploidy) and thus not treatable. However, a consecutive series of miscarriages points to a repetitive cause that is non-chromosomal and is potentially remediable. Since RPL is most commonly due to a uterine pathology or immunologic causes that are potentially treatable, it follows that early chromosomal evaluation of products of conception could point to a potentially treatable situation. Thus I strongly recommend that such testing be done in most cases of miscarriage. Doing so will avoid a great deal of unnecessary heartache for many patients.
Establishing the correct diagnosis is the first step toward determining effective treatment for couples with RPL. It results from a problem within the pregnancy itself or within the uterine environment where the pregnancy implants and grows. Diagnostic tests useful in identifying individuals at greater risk for a problem within the pregnancy itself include:
Karyotyping (chromosome analysis) both prospective parents
•Assessment of the karyotype of products of conception derived from previous miscarriage specimens
•Ultrasound examination of the uterine cavity after sterile water is injected or sonohysterogram, fluid ultrasound, etc.)
•Hysterosalpingogram (dye X-ray test)
•Hysteroscopic evaluation of the uterine cavity

TREATMENT OF RPL
Treatment for Anatomic Abnormalities of the Uterus: This involves restoration through removal of local lesions such as fibroids, scar tissue, and endometrial polyps or timely insertion of a cervical cerclage (a stitch placed around the neck of the weakened cervix) or the excision of a uterine septum when indicated.
Treatment of Thin Uterine Lining: A thin uterine lining has been shown to correlate with compromised pregnancy outcome. Often this will be associated with reduced blood flow to the endometrium. Such decreased blood flow to the uterus can be improved through treatment with sildenafil and possibly aspirin.
Sildenafil (Viagra) Therapy. Viagra has been used successfully to increase uterine blood flow. However, to be effective it must be administered starting as soon as the period stops up until the day of ovulation and it must be administered vaginally (not orally). Viagra in the form of vaginal suppositories given in the dosage of 25 mg four times a day has been shown to increase uterine blood flow as well as thickness of the uterine lining. To date, we have seen significant improvement of the thickness of the uterine lining in about 70% of women treated. Successful pregnancy resulted in 42% of women who responded to the Viagra. It should be remembered that most of these women had previously experienced repeated IVF failures.
Use of Aspirin: This is an anti-prostaglandin that improves blood flow to the endometrium. It is administered at a dosage of 81 mg orally, daily from the beginning of the cycle until ovulation.
Treating Immunologic Implantation Dysfunction with Selective Immunotherapy: Modalities such as IL/IVIg, heparinoids (Lovenox/Clexane), and corticosteroids (dexamethasone, prednisone, prednisolone) can be used in select cases depending on autoimmune or alloimmune dysfunction.
The Use of IVF in the Treatment of RPL
In the following circumstances, IVF is the preferred option:
1.When in addition to a history of RPL, another standard indication for IVF (e.g., tubal factor, endometriosis, and male factor infertility) is superimposed.
2.In cases where selective immunotherapy is needed to treat an immunologic implantation dysfunction.
The reason for IVF being a preferred approach in such cases is that in order to be effective, the immunotherapy needs to be initiated well before spontaneous or induced ovulation. Given the fact that the anticipated birthrate per cycle of COS with or without IUI is at best about 15%, it follows that short of IVF, to have even a reasonable chance of a live birth, most women with immunologic causes of RPL would need to undergo immunotherapy repeatedly, over consecutive cycles. Conversely, with IVF, the chance of a successful outcome in a single cycle of treatment is several times greater and, because of the attenuated and concentrated time period required for treatment, IVF is far safer and thus represents a more practicable alternative
Since embryo aneuploidy is a common cause of miscarriage, the use of preimplantation genetic diagnosis (PGD), with tests such as CGH, can provide a valuable diagnostic and therapeutic advantage in cases of RPL. PGD requires IVF to provide access to embryos for testing.
There are a few cases of intractable alloimmune dysfunction due to absolute DQ alpha matching where Gestational Surrogacy or use of donor sperm could represent the only viable recourse, other than abandoning treatment altogether and/or resorting to adoption. Other non-immunologic factors such as an intractably thin uterine lining or severe uterine pathology might also warrant that last resort consideration be given to gestational surrogacy.
The good news is that if a couple with RPL is open to all of the diagnostic and treatment options referred to above, a live birthrate of 70%–80% is ultimately achievable.

Hello, I had my first hcg draw at 5w4d and it was 835H, the second one was done at 5w6d and it is 1347H. Are these numbers good?
It could be OK!…….Repeat 2 days later to see of it doubles…then do an US in 1 week!
Good luck and G-d bless!

Hello Dr Sher,
Is a day 5 embryo good or day 6 embryo good to do a frozen embryo transfer? Both the embryos are normal euploid but I just wanted your inputs.
Thank you.
If they are euploid, both day 5 and day 6 blastocysts are good!
Good luck!
Geoff Sher
