Respectfully, in my experience day 7 blastocysts are not worthy of transfer. They rarely iuf ever, will propagate viable pregnancies.

• IVF FAILURE WITH “NORMAL” EMBRYOS: EXAMINING AND ADDRESSING ANATOMICAL AND IMMUNOLOGIC CAUSES.

Implantation dysfunction is often overlooked as a significant reason for IVF failure. This is especially true when IVF failure is unexplained, or when there are recurring pregnancy losses or underlying issues with the uterus, such as endo-uterine surface lesions, thin uterine lining (endometrium), or immunological factors.
IVF success rates have been improving in the past decade. Currently, in the United States, the average live birth rate per embryo transfer for women under 40 years old using their own eggs is about 2:5 per woman undergoing embryo transfer. However, there is a wide range of success rates among different IVF programs, varying from 20% to almost 50%. Based on these statistics, most women in the United States need to undergo two or more IVF-embryo transfer attempts to have a baby. Many IVF practitioners in the United States attribute the differences in success rates to variations in expertise among embryology laboratories, but this is not entirely accurate. Other factors, such as differences in patient selection, the failure to develop personalized protocols for ovarian stimulation, and the neglect of infectious, anatomical, and immunological factors that affect embryo implantation, are equally important.
Approximately 80% of IVF failures occur due to “embryo incompetency,” mainly caused by ( irregularities in chromosome number (aneuploidy), which is often related to the advancing age of the woman, diminished ovarian reserve ( DOR) but can also be influenced by the ovarian stimulation protocol chosen, and sperm dysfunction (male infertility). However, in around 20% of cases with dysfunction, failure is caused by problems with embryo implantation.
This section will focus on embryo implantation dysfunction and IVF failure which in the vast majority of cases is caused by:
1. 1. Anatomical irregularities of the inner uterine surface:
2. a) Surface lesions such as polyps/fibroids/ scar tissue
3. b)endometrial thickness
4.
5. 2. Immunologic Implantation Dysfunction ( IID)lesions
6. a)Autoimmune IID
7. b) Alloimmune IID

1. ANATOMICAL IMPLANTATION DYSFUNCTION
a) Surface lesions such as polyps/fibroids/ scar tissue
When there are problems with the structure of the uterus, it can lead to difficulties in getting pregnant. While uterine fibroids usually don’t cause infertility, they can affect fertility when they distort the uterine cavity or protrude through the lining. Even small fibroids located just beneath the lining and protruding into the cavity can decrease the chances of the embryo attaching. Multiple fibroids within the uterine wall that encroach upon the cavity can disrupt blood flow, impair estrogen delivery, and prevent proper thickening of the lining. These issues can be identified through ultrasound during the menstrual cycle’s proliferative phase. Any lesion on the uterine surface, such as submucous fibroids, adhesions, endometrial polyps, or placental polyps, can interfere with implantation by causing a local inflammatory response similar to the effect of an intrauterine contraceptive device (IUD).
Clearly, even small uterine lesions can have a negative impact on implantation. Considering the high costs and emotional toll associated with in vitro fertilization (IVF) and related procedures, it is reasonable to perform diagnostic tests like hysterosalpingography (HSG), fluid ultrasound examination (hysterosonogram), or hysteroscopy before starting IVF. Uterine lesions that can affect implantation often require surgical intervention. In most cases, procedures like dilatation and curettage (D&C) or hysteroscopic resection are sufficient. Rarely a laparotomy may be needed. Such interventions often lead to an improvement in the response of the uterine lining.
Hysterosonogram( HSN/saline ultrasound) is a procedure where a sterile saline solution is injected into the uterus through the cervix using a catheter. Vaginal ultrasound is then used to examine the fluid-filled cavity for any irregularities that might indicate surface lesions like polyps, fibroid tumors, scarring, or a septum. When performed by an expert, HSN is highly effective in detecting even the smallest lesions and can supplant hysteroscopy in certain cases. HSN is less expensive, less invasive/traumatic, and equally effective as hysteroscopy. The only drawback is that if a lesion is found, hysteroscopy may still be needed for treatment.
Hysteroscopy is a diagnostic procedure performed in an office setting with minimal discomfort to the patient. It involves inserting a thin, lighted instrument called a hysteroscope through the vagina and cervix into the uterus to examine the uterine cavity. Normal saline is used to distend the uterus during the procedure. Like HSN, hysteroscopy allows for direct visualization of the inside of the uterus to identify defects that could interfere with implantation. We have observed that around one in eight IVF candidates have lesions that need attention before undergoing IVF to optimize the chances of success. I strongly recommend that all patients undergo therapeutic surgery, usually hysteroscopy, to correct any identified issues before proceeding with IVF. Depending on the severity and nature of the problem, hysteroscopy may require general anesthesia and should be performed in a surgical facility equipped for laparotomy if necessary.
b) Thickness of the uterine lining (endometrium)
As far back as In 1989, I and my team made an important discovery about using ultrasound to assess the thickness of the endometrium during the late proliferative phase of both “ natural” and hormone-stimulated cycles. The assessment helped predict the chances of conception. We found that an ideal thickness of over 9mm at the time of ovulation , egg retrieval or with the commencement of progesterone therapy in embryo recipient cycles ( e.g., IVF with egg donation, gestational, surrogacy and embryo adoption) was associated with optimal implantation rates, while an endometrial thickness of less than 8 mm was associated with failure to implant or early pregnancy loss in the vast majority of cases. An endometrium measuring <8mm was almost invariably associated with failure to implant or early pregnancy loss in the while an endometrium measuring 8 to 9 mm was regarded as being intermediate, and while pregnancies did occur in this range, the rates were only slightly lower than with an optimal lining of 9 mm
A "poor" uterine lining typically occurs when the innermost layer of the endometrium (basal or germinal endometrium) is unable to respond to estrogen by developing a thick enough outer "functional" layer to support successful embryo implantation and placental development. The “functional” layer, which accounts for two-thirds of the total endometrial thickness, is shed during menstruation if pregnancy does not occur.
The main causes of a poor uterine lining are:
1. Damage to the basal endometrium due to:
o Inflammation of the endometrium (endometritis), often resulting from retained products of conception after abortion, miscarriage, or childbirth.
o Surgical trauma caused by aggressive dilatation and curettage (D&C).
2. Insensitivity of the basal endometrium to estrogen due to:
o Prolonged (back to back) use of clomiphene citrate for ovarian stimulation or…
o Prenatal exposure to diethylstilbestrol (DES), a drug given to prevent miscarriage in the 1960s.
3. Overexposure of the uterine lining to male hormones produced by the ovaries or administered during ovarian stimulation (primarily testosterone):
o Older women, women with DOR (poor responders), and women with polycystic ovarian syndrome (PCOS) often have increased biological activity of luteinizing hormone (LH), leading to testosterone overproduction by the ovarian connective tissue (stroma/theca). This effect can be further amplified when certain ovarian stimulation protocols were high doses of menotropins ( e.g., Menopur) are used.
4. Reduced blood flow to the basal endometrium caused by:
o Multiple uterine fibroids, especially if they are located beneath the endometrium (submucosal).
o Uterine adenomyosis, which involves extensive abnormal invasion of endometrial glands into the uterine muscle.
In 1996 I introduced the Vaginal administration of Sildenafil (Viagra) to improve endometrial thickening. The selective administration of Sildenafil has shown great promise in improving uterine blood flow and increasing endometrial thickening in cases of thin endometrial linings. When administered vaginally, it is quickly absorbed and reaches high concentrations in the uterine blood system, diluting as it enters the systemic circulation. This method has been found to have minimal systemic side effects. However, it is important to note that Viagra may not be effective in all cases, as some cases of thin uterine linings may involve permanent damage to the basal endometrium, rendering it unresponsive to estrogen.
Severe endometrial damage leading to poor responsiveness to estrogen can occur in various situations. These include post-pregnancy endometritis (inflammation after childbirth), chronic granulomatous inflammation caused by uterine tuberculosis (rare in the United States), and significant surgical injury to the basal endometrium (which can happen after aggressive D&C procedures).

2. IMMUNOLOGIC IMPLANTATION DYSFUNCTION (IID)
There is a growing recognition that problems with the immune function in the uterus can lead to embryo implantation dysfunction. The failure of proper immunologic interaction during implantation has been implicated as a cause of recurrent miscarriage, late pregnancy fetal loss, IVF failure, and infertility. Some immunologic factors that may contribute to these issues include antiphospholipid antibodies (APA), antithyroid antibodies (ATA) , and activated natural killer cells (NKa).
• Activated natural Killer Cells (NKa):
During ovulation and early pregnancy, the uterine lining is frequented by NK cells and T-cells, which together make up more than 80% of the immune cells in the uterine lining. These cells travel from the bone marrow to the endometrium where they proliferate under hormonal regulation. When exposed to progesterone, they produce TH-1 and TH-2 cytokines. TH-2 cytokines help the trophoblast (embryo's "root system") to penetrate the uterine lining, while TH-1 cytokines induce apoptosis (cell suicide), limiting placental development to the inner part of the uterus. The balance between TH1 and TH-2 cytokines is crucial for optimal placental development. NK cells and T-cells contribute to cytokine production. Excessive TH-1 cytokine production is harmful to the trophoblast and endometrial cells, leading to programmed cell death and ultimately to implantation failure. Functional NK cells reach their highest concentration in the endometrium around 6-7days after ovulation or exposure to progesterone, which coincides with the time of embryo implantation. It’s important to note that measuring the concentration of blood NK cells doesn't reflect NK cell activation (NKa). The activation of NK cells is what matters. In certain conditions like endometriosis, the blood concentration of NK cells may be below normal, but NK cell activation is significantly increased.
There are several laboratory methods to assess NK cell activation (cytotoxicity), including immunohistochemical assessment of uterine NK cells and measuring TH-1 cytokines in the uterus or blood. However, the K-562 target cell blood test remains the gold standard. In this test, NK cells isolated from a woman's blood are incubated with specific "target cells," and the percentage of killed target cells is quantified. More than 12% killing indicates a level of NK cell activation that usually requires treatment. Currently, there are only a few Reproductive Immunology Reference Laboratories in the USA capable of reliably performing the K-562 target cell test.
There is a common misconception that adding IL (intralipid) or Intravenous gammaglobulin (IVIg) to NK cells can immediately downregulate NK cell activity. However, neither IL and IVIg cannot significantly suppress already activated NK cells. They are believed to work by regulating NK cell progenitors, which then produce downregulated NK cells. To assess the therapeutic effect, IL/IVIg infusion should be done about 14 days before embryos are transferred to the uterus to ensure a sufficient number of normal functional NK cells are present at the implantation site during embryo transfer. Failure to recognize this reality has led to the erroneous demand from IVF doctors for Reproductive Immunology Reference Laboratories to report on NK cell activity before and immediately after exposure to IVIg or IL at different concentrations. However, since already activated NK cells cannot be deactivated in the laboratory, assessing NKa suppression in this way has little clinical benefit. Even if blood is drawn 10-14 days after IL/IVIg treatment, it would take another 10-14 days to receive the results, which would be too late to be practically advantageous.
• Antiphospholipid Antibodies:
Many women who struggle with IVF failure or recurrent pregnancy loss, as well as those with a personal or family history of autoimmune diseases like lupus erythematosus, rheumatoid arthritis, scleroderma, and dermatomyositis, often test positive for antiphospholipid antibodies (APAs). Over 30 years ago, I proposed a treatment for women with positive APA tests. This involved using a low dose of heparin to improve the success of IVF implantation and increase birth rates. Research indicated that heparin could prevent APAs from affecting the embryo's "root system" ( the trophoblast), thus enhancing implantation. We later discovered that this therapy only benefits women whose APAs target specific phospholipids (phosphatidylethanolamine and phosphatidylserine). Nowadays, longer-acting low molecular weight heparinoids like Lovenox and Clexane have replaced heparin.
• Antithyroid Antibodies ( thyroid peroxidase -TPO and antithyroglobulin antibodies (TGa)
Between 2% and 5% of women of the childbearing age have reduced thyroid hormone activity (hypothyroidism). Women with hypothyroidism often manifest with reproductive failure i.e., infertility, unexplained (often repeated) IVF failure, or recurrent pregnancy loss (RPL). The condition is 5-10 times more common in women than in men. In most cases hypothyroidism is caused by damage to the thyroid gland resulting from thyroid autoimmunity (Hashimoto’s disease) caused by damage done to the thyroid gland by antithyroglobulin and antimicrosomal auto-antibodies. The increased prevalence of hypothyroidism and thyroid autoimmunity (TAI) in women is likely the result of a combination of genetic factors, estrogen-related effects, and chromosome X abnormalities. This having been said, there is significantly increased incidence of thyroid antibodies in non-pregnant women with a history of infertility and recurrent pregnancy loss and thyroid antibodies can be present asymptomatically in women without them manifesting with overt clinical or endocrinologic evidence of thyroid disease. In addition, these antibodies may persist in women who have suffered from hyper- or hypothyroidism even after normalization of their thyroid function by appropriate pharmacological treatment. The manifestations of reproductive dysfunction thus seem to be linked more to the presence of thyroid autoimmunity (TAI) than to clinical existence of hypothyroidism and treatment of the latter does not routinely result in a subsequent improvement in reproductive performance. It follows that if antithyroid autoantibodies are associated with reproductive dysfunction they may serve as useful markers for predicting poor outcome in patients undergoing assisted reproductive technologies. Some years back, I reported on the fact that 47% of women who harbor thyroid autoantibodies, regardless of the absence or presence of clinical hypothyroidism, have activated uterine natural killer cells (NKa) cells and cytotoxic lymphocytes (CTL) and that such women often present with reproductive dysfunction. We demonstrated that appropriate immunotherapy with IVIG or intralipid (IL) and steroids subsequently often results in a significant improvement in reproductive performance in such cases.

Almost 50% of women with antithyroid antibodies do not have activated cytotoxic T lymphocytes (CTL) or natural killer cells (NK cells). This suggests that the antibodies themselves may not be the direct cause of reproductive dysfunction. Instead, the activation of CTL and NK cells, which occurs in about half of the cases with thyroid autoimmunity (TAI), is likely an accompanying phenomenon that damages the early "root system" (trophoblast) of the embryo during implantation.
Treating women who have both antithyroid antibodies and activated NK cells/CTL with intralipid (IL) and steroids improves their chances of successful reproduction. However, women with antithyroid antibodies who do not have activated NK cells/CTL do not require this treatment.
• Treatment Options for IID:
1. Intralipid (IL) Therapy: IL is a mixture of soybean lipid droplets in water, primarily used for providing nutrition. When administered intravenously, IL supplies essential fatty acids that can activate certain receptors in NK cells, reducing their cytotoxic activity and enhancing implantation. IL, combined with corticosteroids, suppresses the overproduction of pro-inflammatory cytokines by NK cells, improving reproductive outcomes. IL is cost-effective and has fewer side effects compared to other treatments like IVIg.
2. Intravenous immunoglobulin-G (IVIg) Therapy: In the past, IVIg was used to down-regulate activated NK cells. However, concerns about viral infections and the high cost led to a decline in its use. IVIg can be effective, but IL has become a more favorable and affordable alternative.
3. Corticosteroid Therapy: Corticosteroids, such as prednisone and dexamethasone, are commonly used in IVF treatment. They have an immunomodulatory effect and reduce TH-1 cytokine production by CTL. When combined with IL or IVIg, corticosteroids enhance the implantation process. Treatment typically starts 10-14 days before embryo transfer and continues until the 10th week of pregnancy.
4. Heparinoid Therapy: Low molecular weight heparin (Clexane, Lovenox)can improve IVF success rates in women with antiphospholipid antibodies (APAs) and may prevent pregnancy loss in certain thrombophilias when used during treatment. It is administered subcutaneously once daily from the start of ovarian stimulation.
5. TH-1 Cytokine Blockers (Enbrel, Humira): TH-1 cytokine blockers have limited effectiveness in the IVF setting and, in my opinion, no compelling evidence supports their use. They may have a role in treating threatened miscarriage caused by CTL/NK cell activation, but not for IVF treatment. TH-1 cytokines are needed for cellular response, during the early phase of implantation, so completely blocking them could hinder normal implantation.
5. Baby Aspirin and IVF: Baby aspirin doesn't offer much value in treating implantation dysfunction (IID) and may even reduce the chance of success. This is because aspirin thins the blood and increases the risk of bleeding, which can complicate procedures like egg retrieval or embryo transfer during IVF, potentially compromising its success.
6. Leukocyte Immunization Therapy (LIT):LIT involves injecting the male partner's lymphocytes into the mother to improve the recognition of the embryo as "self" and prevent rejection. LIT can up-regulate Treg cells and down-regulate NK cell activation, improving the balance of TH-1 and TH-2 cells in the uterus. However, the same benefits can be achieved through IL (Intralipid) therapy combined with corticosteroids. IL is more cost-effective, and the use of LIT is prohibited by law in the USA.
Types of Immunologic Implantation Dysfunction (IID) and NK Cell Activation:
1. Autoimmune Implantation Dysfunction: Women with a personal or family history of autoimmune conditions like Rheumatoid arthritis, Lupus Erythematosus, thyroid autoimmune disease (Hashimoto's disease and thyrotoxicosis), and endometriosis (in about one-third of cases) may experience autoimmune IID. However, autoimmune IID can also occur without any personal or family history of autoimmune diseases. Treatment for NK cell activation in IVF cases complicated by autoimmune IID involves a combination of daily oral dexamethasone from the start of ovarian stimulation until the 10th week of pregnancy, along with 20% intralipid (IL) infusion 10 days to 2 weeks before embryo transfer. With this treatment, the chance of a viable pregnancy occurring within two completed embryo transfer attempts is approximately 70% for women <40 years old who have normal ovarian reserve.
2. Alloimmune Implantation Dysfunction: NK cell activation occurs when the uterus is exposed to an embryo that shares certain genotypic (HLA/DQ alpha) similarities with the embryo recipient.
• Partial DQ alpha/HLA genetic matching: Couples who share only one DQ alpha/HLA gene are considered to have a "partial match." If NK cell activation is also present, this partial match puts the couple at a disadvantage for IVF success. However, it's important to note that DQ alpha/HLA matching, whether partial or total, does not cause IID without associated NK cell activation. Treatment for partial DQ alpha/HLA match with NK cell activation involves IL infusion and oral prednisone as adjunct therapy. IL infusion is repeated every 2-4 weeks after pregnancy is confirmed and continued until the 24th week of gestation. In these cases, only one embryo is transferred at a time to minimize the risk of NK cell activation.
• Total (Complete) Alloimmune Genetic Matching: A total alloimmune match occurs when the husband's DQ alpha genotype matches both that of the partner. Although rare, this total match along with NK cell activation significantly reduces the chance of a viable pregnancy resulting in a live birth at term. In some cases, the use of a gestational surrogate may be necessary.
It should be emphasized that poor embryo quality is not always the main cause of reproductive dysfunction and that the complex interaction between embryonic cells and the lining of the uterus plays a critical role in successful implantation. Women with personal or family histories of autoimmune disease or endometriosis and those with unexplained (often repeated) IVF failure or recurrent pregnancy loss, often have immunologic implantation dysfunction (IID as the underlying cause . For such women, it is important to understand how IID leads to reproductive failure and how selective treatment options such as intralipid (IL), corticosteroid and heparinoid therapy, can dramatically improve reproductive outcomes. Finally, there is real hope that proper identification and management of IID can significantly improve the chance of successful reproduction and ultimately contribute to better quality of life after birth.

PS:I am not a big believer in the value of Alice/Emma testing!

The blastocyst and the endometrium are in a constant state of cross-talk. In order for successful implantation to take place, the blastocyst must be at the appropriate stage of development and needs to signal a well synchronized endometrium to ‘accept it”. This dialogue between embryo and endometrium involves growth factors, cytokines, immunologic accommodations, cell adhesion molecules, and transcription factors. These are all mostly genetically driven but are also heavily influenced by numerous physiologic, pathophysiologic, hormonal and molecular mechanisms capable of profoundly affecting the receptivity of the secretory endometrium to the overtures made by the embryo, to implant.
Embryo implantation takes place 6-9 days after ovulation. This period is commonly referred to as the “window of implantation (WOI)”. In the past it was believed that as long as the embryo reached the uterus in this 4 day time frame, its chance of implanting would not be affected.
In 2013, after evaluating 238 genes in the secretory endometrium and applying bioformatics, Ruiz-Alonzo, et all introduced the Endometrial Receptivity Array (ERA) . Using this test, they categorized mid-secretory endometria into 4 categories: “a) proliferative, b) pre-receptive, c) receptive or d) post-receptive”. They claimed that women with pre-receptive or post-receptive endometria were more likely to experience failed implantation post-embryo transfer (ET).
It was in large part this research which suggested that the concept of a relatively “wide” (4day) WOI, was flawed, that an optimal WOI is likely much narrower and could be a critical factor in determining the success or failure of implantation post-ET. Ruiz-Alonzo also reported that about 25% of women with recurrent IVF failure (RIF), have pre, or post-receptive endometria. They presented data suggesting that viable IVF pregnancy rates could be enhanced,
by deferring FET by about 24 hours in women who had pre-receptive endometria and bringing ET forward by the same amount of time, in women with post-receptive endometria,

Another key question relates to the reproducibility of ERA test results. We have noted that when performed on the same subject multiple times results can vary from “pre-receptive” to “post-receptive,” even when done on consecutive cycles. This raises doubts about how a test conducted before the actual embryo transfer cycle can accurately predict the ideal implantation window for a future transfer.

Presently, available data is inconclusive. As an example, here following recent studies are 2 dissenting opinions regarding the value for ERA:
• Basil and Casper (2018) state: “Performing the ERA test in a mock cycle prior to a FET does not seem to improve the ongoing pregnancy rate in good prognosis patients. Further large prospective studies are needed to elucidate the role of ERA testing in both good prognosis patients and in patients with recurrent implantation failure”
• Churchill and Comstock (2017) conclude:” In our preliminary observations, the non-receptive ERA group had similar live birth rates compared to the receptive ERA group. It appears the majority of the pregnancies conceived in the non-receptive group occurred during ovulatory cycles and thus a non-receptive ERA in a medicated cycle likely does not have prognostic value for ovulatory cycles. Larger studies are needed to assess the prognostic value of ERA testing in the gen-eral infertility population.”
There are additional negatives that relate to the considerable emotional and financial cost of doing ERA testing:
1. The process costs $600-$1500
2. It requires that the patient undergo egg retrieval, vitrify (cryobank) all blastocysts, for 1 or more cycles to allow their hormonal equilibrium to restore, do an ERA biopsy to determine the synchronicity of the endometrium, wait a few weeks for the results of the test and thereupon engage in undertaking an additional natural or hormonal preparation cycle for timed FET. This represents a significant time lapse, emotional cost and additional expense.
Presently, ERA testing is advocated selectively for women who have experienced several IVF failures or repeated pregnancy losses. However, some authorities advocate that it become routine for women undergoing all IVF.
The additional financial cost inherent in the performance of the ERA test), the considerable time delay in getting results, the fact that awaiting results of testing and preparing the patient for embryo transfer (ET), of necessity extends the completion of the IVF/ET process by at least a few months, all serve to increase the emotional and financial hardship confronting patients undergoing ERA. Such considerations, coupled with the current absence of conclusive data that confirm efficacy, are arguments against the widespread use of ERA .
Gold standard statistical analyses require that all confounding variables be controlled while examining the effect of altering the one under assessment. There is an obvious interplay of numerous, ever-changing variables involved in outcome following ET, e.g., embryo competency, anatomical configuration of the uterus and the contour of the endometrial cavity, endometrial thickness, immunologic and molecular factors as well as the very important effect of technical skill/expertise in performing the ET procedure …(to mention but a few). It follows that it is virtually impossible to draw reliable conclusions from IVF-related randomized controlled studies that rely solely on outcome as the end-point. This applies equally to results reported following “ gold standard” testing on the efficacy of ERA and, is one of the main reasons why I question the reliability of reported data (positive or negative).
The fact is that IVF (and related technologies) constitute neither a “pure science” nor a “pure art”. Rather they represent an “art-science blend”, where scientific principles applied to longitudinal experience and technical expertise coalesce to produce a biomedical product that will invariably differ (to a greater or lesser degree) from one set of clinical circumstances to another.
Since, the ultimate goal of applied Assisted Reproductive Medicine is to safely achieve the birth of a viable and healthy baby, the tools we apply, that are aimed at achieving this endpoint, are honed through the adaptation of scientific principles and concepts, experience and expertise, examined and tested longitudinally over time. Needless to say, the entire IVF/ET process is of necessity subject to change and adaptation as new scientific and technical developments emerge.
This absolutely applies to the ERA .

Understanding the impact of age and ovarian reserve on the success of in vitro fertilization (IVF) is crucial when it comes to reproductive health. This article aims to simplify and clarify these concepts, emphasizing their significance in the selection of ovarian stimulation protocols for IVF. By providing you with this information, we hope to shed light on the importance of considering these factors and making informed decisions regarding fertility treatments.
1. The Role of Eggs in Chromosomal Integrity: In the process of creating a healthy embryo, it is primarily the egg that determines the chromosomal integrity, which is crucial for the embryo’s competency. A competent egg possesses a normal karyotype, increasing the chances of developing into a healthy baby. It’s important to note that not all eggs are competent, and the incidence of irregular chromosome numbers (aneuploidy) increases with age.
2. Meiosis and Fertilization: Following the initiation of the LH surge or the hCG trigger shot, the egg undergoes a process called meiosis, halving its chromosomes to 23. During this process, a structure called the polar body is expelled from the egg, while the remaining chromosomes are retained. The mature sperm, also undergoing meiosis, contributes 23 chromosomes. Fertilization occurs when these chromosomes combine, resulting in a euploid embryo with 46 chromosomes. Only euploid embryos are competent and capable of developing into healthy babies.
3. The Significance of Embryo Ploidy: Embryo ploidy, referring to the numerical chromosomal integrity, is a critical factor in determining embryo competency. Aneuploid embryos, which have an irregular number of chromosomes, are often incompetent and unable to propagate healthy pregnancies. Failed nidation, miscarriages, and chromosomal birth defects can be linked to embryo ploidy issues. Both egg and sperm aneuploidy can contribute, but egg aneuploidy is usually the primary cause.
4. Embryo Development and Competency: Embryos that develop too slowly or too quickly, have abnormal cell counts, contain debris or fragments, or fail to reach the blastocyst stage are often aneuploid and incompetent. Monitoring these developmental aspects can provide valuable insights into embryo competency.
5. Diminished Ovarian Reserve (DOR): As women advance in their reproductive age, the number of remaining eggs in the ovaries decreases. Diminished ovarian reserve (DOR) occurs when the egg count falls below a certain threshold, making it more challenging to respond to fertility drugs effectively. This condition is often indicated by specific hormone levels, such as elevated FSH and decreased AMH. DOR can affect women over 40, but it can also occur in younger

Why IVF should be regarded as treatment of choice for older women an those who have diminished ovarian reserve ( DOR):
Understanding the following factors will go a long way in helping you to make an informed decision and thereby improve the chances of a successful IVF outcome.
1. Age and Ovarian Reserve: Chronological age plays a vital role in determining the quality of eggs and embryos. As women age, there is an increased risk of aneuploidy (abnormal chromosome numbers) in eggs and embryos, leading to reduced competency. Additionally, women with declining ovarian reserve (DOR), regardless of their age, are more likely to have aneuploid eggs/embryos. Therefore, it is crucial to address age-related factors and ovarian reserve to enhance IVF success.
2. Excessive Luteinizing Hormone (LH) and Testosterone Effects: In women with DOR, their ovaries and developing eggs are susceptible to the adverse effects of excessive LH, which stimulates the overproduction of male hormones like testosterone. While some testosterone promotes healthy follicle growth and egg development, an excess of testosterone has a negative impact. Therefore, in older women or those with DOR, ovarian stimulation protocols that down-regulate LH activity before starting gonadotropins are necessary to improve egg/embryo quality and IVF outcomes.
3. Individualized Ovarian Stimulation Protocols: Although age is a significant factor in aneuploidy, it is possible to prevent further decline in egg/embryo competency by tailoring ovarian stimulation protocols. Here are my preferred protocols for women with relatively normal ovarian reserve:
a. Conventional Long Pituitary Down Regulation Protocol:
• Begin birth control pills (BCP) early in the cycle for at least 10 days.
• Three days before stopping BCP, overlap with an agonist like Lupron for three days.
• Continue daily Lupron until menstruation begins.
• Conduct ultrasound and blood estradiol measurements to assess ovarian status.
• Administer FSH-dominant gonadotropin along with Menopur for stimulation.
• Monitor follicle development through ultrasound and blood estradiol measurements.
• Trigger egg maturation using hCG injection, followed by egg retrieval.
b. Agonist/Antagonist Conversion Protocol (A/ACP):
• Similar to the conventional long down regulation protocol but replace the agonist with a GnRH antagonist from the onset of post-BCP menstruation until the trigger day.
• Consider adding supplementary human growth hormone (HGH) for women with DOR.
• Consider using “priming” with estrogen prior to gonadotropin administration
c. Protocols to Avoid for Older Women or Those with DOR: Certain ovarian stimulation protocols may not be suitable for older women or those with declining ovarian reserve:
• Microdose agonist “flare” protocols
• High dosages of LH-containing fertility drugs such as Menopur
• Testosterone-based supplementation
• DHEA supplementation
• Clomiphene citrate or Letrozole
• Low-dosage hCG triggering or agonist triggering for women with DOR

Preimplantation Genetic Screening/Testing(PGS/T): PGS/T is a valuable tool for identifying chromosomal abnormalities in eggs and embryos. By selecting the most competent (euploid) embryos, PGS/T significantly improves the success of IVF, especially in older women or those with DOR.
Understanding the impact of advancing age and declining ovarian reserve on IVF outcomes is essential when making decisions about fertility treatments. Age-related factors can affect egg quality and increase the likelihood of aneuploid embryos with resultant IVF failure. Diminished ovarian reserve (DOR) further complicates the process. By considering these factors, you can make informed choices and work closely with fertility specialists to optimize your chances of success.

When women with endometriosis-related infertility seek treatment, they are often advised to try ovarian stimulation with or without intrauterine insemination (IUI) as a first option. However, it’s important to clarify the reality and set the record straight. In vitro fertilization (IVF) offers distinct advantages and a higher chance of success compared to IUI. Let’s explore why IVF should often be considered as the primary approach for women with endometriosis.
1. The Toxic Pelvic Factor:
Endometriosis causes the lining of the uterus to grow outside the uterus. As these deposits bleed over time, they release toxins into the pelvic secretions. These toxins coat the peritoneum, the membrane that covers the abdominal and pelvic organs. When eggs are released from the ovaries, they must pass through these toxic secretions to reach the sperm in the fallopian tubes. The toxins alter the egg’s envelopment, making it less receptive to fertilization. This explains why women with endometriosis are far less likely to conceive naturally, following ovulation induction or after surgical attempts to eliminate the condition. Consider the following: .
• Ovulation induction with or without intrauterine insemination (IUI) is commonly recommended for women with mild to moderately severe endometriosis. However, while fertility drugs can stimulate the growth of multiple follicles, ovulatory women (including those with mild to moderately severe endometriosis) usually ovulate only one egg a time. Therefore, the use of fertility drugs in such cases doesn’t significantly improve pregnancy potential.
• Surgery to remove endometriotic deposits or adhesions: Surgical removal of visible endometriotic lesions in mild to moderate endometriosis does not usually improve pregnancy potential significantly. This is because endometriosis is an ongoing process, with new lesions constantly developing. Even after the visible lesions are removed, invisible lesions continue to release toxins that can compromise natural fertilization. In contrast, IVF bypasses the toxic pelvic environment by retrieving eggs from the ovaries, fertilizing them outside the body, and transferring resulting embryos to the uterus. This makes IVF the preferred treatment for endometriosis-related infertility.

2. The Immunologic Factor:

Approximately one third of women with endometriosis also have an immunologic implantation dysfunction (IID) related to the activation of uterine natural killer cells (NKa). This requires selective immunotherapy with Intralipid infusions or heparinoids, which can be effectively implemented in combination with IVF.

3. 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 inside the ovaries 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. Endometriomas of >1 cm in size should in my opinion be addressed because in my opinion, they can and do adversely affect the quality of eggs produced in the affected ovary. We confirmed this effect in a study where we evaluated egg quality in a number of women who had one or more endometriomas involving one ovary while the contralateral ovary was unaffected. We were able to show that those eggs aspirated from follicles in the endometrioma-affected ovary were of markedly reduced quality (and, the embryos and blastocysts they propagated were fewer in number and of markedly reduced quality as compared to those harvested from the un affected ovary.

• Conventional surgical treatment performed to remove endometriomas involvers laparoscopy or laparotomy with aspiration of the cyst content followed by complete removal and/or ablation/obliteration of the cyst wall. This should be done at least 6 weeks in advance of egg retrieval, in my opinion. Such treatment is associated with pain and a risk of surgical complications.
• An alternative approach which I and my colleagues first reported on more than 2 decades ago, known as Ovarian Sclerotherapy is a highly effective, inexpensive and safe outpatient method for treating endometriomas in women planning to undergo IVF. 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. It is in my opinion, unfortunate that Ovarian Sclerotherapy is not readily available in this country.

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.
IVF is by far the most successful approach to dealing with endometriosis-related infertility , especially when it comes to women above the age of 35 years, those who have moderate or severe disease and for women who have DOR. Understanding how endometriosis affects IVF outcomes can help make informed decisions about treatment. By providing a more favorable environment for fertilization and implantation. IVF offers much higher success rates when compared to ovulation induction with or without IUI or surgical correction. Simply put……If you’re facing infertility due to endometriosis, it’s worth considering IVF as the first line of treatment to increase your chances of having a baby.
