• IMPLANTATION DYSFUNCTION

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. Anatomical irregularities of the inner uterine surface:

1. •  Surface lesions such as polyps/fibroids/ scar tissue
   • endometrial thickness

1.  Immunologic Implantation Dysfunction ( IID)lesions

1. • Autoimmune IID
   • Alloimmune IID

 ANATOMICAL IMPLANTATION DYSFUNCTION

1. 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.

1. 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:

1. • Inflammation of the endometrium (endometritis), often resulting from retained products of conception after abortion, miscarriage, or childbirth.
   • Surgical trauma caused by aggressive dilatation and curettage (D&C).

1. Insensitivity of the basal endometrium to estrogen due to:

1. • Prolonged (back to back) use of clomiphene citrate for ovarian stimulation or…
   • Prenatal exposure to diethylstilbestrol (DES), a drug given to prevent miscarriage in the 1960s.

1. Overexposure of the uterine lining to male hormones produced by the ovaries or administered during ovarian stimulation (primarily testosterone):

1. • 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.

1. Reduced blood flow to the basal endometrium caused by:

1. • Multiple uterine fibroids, especially if they are located beneath the endometrium (submucosal).
   • 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.
6. 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.
7. 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. Humans have 23 pairs of chromosomes: one set from the sperm and one set from the egg that created us. Our sixth pair of chromosomes each contain DQ alpha genes. Again, one of these genes is from the sperm and one is from the egg that created us.

Like the genes for eye color, DQ alpha/HLA gene combinations differ between people. Thus, the male (whose  sperm created an embryo is likely to have different DQ alpha/HLA gene combinations than the potential mother . However, there are rare situations in which the male and the female partners have  DQ-alpha/HLA gene combinations are the same.

The endometrial immune system is programmed to accept embryos with different DQ alpha/HLA gene combinations than its own. This is known as “alloimmune recognition.” So, if the man shares a similar DQ alpha/HLA gene combination with the woman, and his sperm creates an embryo that tries  to implant , her endometrial immune system will see the embryo’s DQ alpha/HLA gene as “too similar” to its own and assume it is a foreign body.

Usually, this will lead to NK/T cell activation, the overproduction of TH-1 cytokines, and reproductive failure (i.e., infertility, and pregnancy loss). The severity with which this occurs is an important determinant of whether total implantation failure will occur or whether there would remain enough residual trophoblastic activity that would allow the pregnancy to limp along until the nutritional supply can no longer meet the demands of the pregnancy, at which point pregnancy loss occurs.

In cases of paternal-maternal DQ alpha/HLA matching, it will often take several pregnancies for NK cell activation to build to the point that women with alloimmune implantation dysfunction will present with clinical evidence of implantation dysfunction. Sometimes it starts off with one or two live births, whereupon NK/T cell activity starts to build, leading to one or more early miscarriages. Eventually the NK/T cell activation is so high that subsequent pregnancies can be lost before the woman is even aware that she was pregnant at all. At this point, she is often diagnosed with secondary, “unexplained” infertility and/or “unexplained” IVF failure.

Alloimmune Implantation Dysfunction is diagnosed by testing the blood of both the male and female partners for matching DQ alpha genes and NK/T cell activation.

There are two types of DQ alpha/HLA genetic matching: 

• 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.

• ENDOMETRIOSIS AND INFERTILITY: A RATIONAL BASIS FOR TREATMENT.

 Women who have endometriosis are much more likely to be infertile. There are several reasons for this:

• First, endometriosis is associated with the presence of toxins in peritoneal secretions. As sperm and egg(s) travel towards the fallopian tubes they are exposed to these toxins which compromise the fertilization process
• Second, in about 25 – 30% of cases, endometriosis is associated with ovulation dysfunction.
• Third, in its most severe form, the condition is associated with scarring and adhesions in the pelvis, resulting in damage to, or blockage of the fallopian tubes, thereby preventing the union of sperm and eggs.
• Fourth, endometriosis is associated with abnormalities of the woman’s immune system which interfere with the ability of the fertilized egg to attach (implant) to the uterine wall.

Until quite recently, we really had no clue as to how reproductive problems associated with endometriosis evolve. Recent medical research has helped shed light on the subject and offers promise with regard to the future treatment of infertility/ reproductive failure associated with this condition. A few examples of recent breakthroughs include the following:

Endometriosis appears to have a genetic (familial) component .In the future, the development of genetic markers might provide an important diagnostic tool.

 Patients with endometriosis have immunologic abnormalities. The most significant of these involve the presence of harmful antibodies known as antiphospholipid antibodies (APA) are in the bloodstream of about 66 percent of women with endometriosis. In about half such cases (i.e., about 1/3 of all cases of endometriosis…regardless of severity) the immunologic implantation is profoundly aggravated by the presence of activated (i.e.  “toxic”) natural killer cells (Nka) and activated cytotoxic lymphocytes (CTLa) in the uterine lining (endometrium). These NKa/CTLa attack the invading trophoblast cells (developing “root system” of the embryo/early conceptus) as soon as it tries to gain attachment to the uterine wall. In most cases, this results in death of the embryo even before the pregnancy is diagnosed and sometimes, in a chemical pregnancy or even an early miscarriage. . As such, many women with endometriosis, rather than being infertile, in the strict sense of the word, often actually experience repeated undetected “mini miscarriages”.

Endometriosis often goes unnoticed for many years. Such patients are frequently erroneously labeled as having “unexplained infertility”, until the diagnosis is finally clinched through direct visualization of the lesions at the time of laparoscopy or laparoscopy. Not surprisingly, many patients with so called “unexplained” infertility, if followed for a number of years, will ultimately reveal endometriosis.

Advanced Endometriosis: In its most advanced stage, anatomical disfiguration is causally linked to infertility. In such cases, inspection at laparoscopy or laparoscopy will usually reveal severe pelvic adhesions, scarring and “chocolate cysts”. However, the quality of life of patients with advanced endometriosis is usually so severely compromised by pain and discomfort, that having a baby is often low on the priority list. Accordingly, such patients are usually often more interested in relatively radical medical and surgical treatment options (might preclude a subsequent pregnancy), such as removal of ovaries, fallopian pubis and even the uterus, as a means of alleviating suffering.

 Moderately Severe Endometriosis. These patients have a modest amount of scarring/ adhesions and endometriotic deposits which are usually detected on the ovaries, fallopian tubes, bladder surface and low in the pelvis, behind the uterus. In such cases, the fallopian tubes are usually opened and functional.

 Mild Endometriosis: These patients who at laparoscopy or laparotomy are found to have a few visible e3ndometrial “implants” but minimal distortion of pelvic anatomy are often erroneously labeled as having “unexplained” infertility. To hold that the there can only infertility can only be attributed to endometriosis if significant anatomical disease can be identified, is to ignore the fact that, biochemical, hormonal and immunological factors profoundly impact fertility. Failure to recognize this salient fact continues to play havoc with the hopes and dreams of many infertile endometriosis patients.

Endometriotic implants produce a toxic “peritoneal factor”

As mentioned above, toxins that impair fertilization are present in the peritoneal secretions of most patients with endometriosis. Impaired fertilization is a feature of endometriosis regardless of its severity. This explains why women with endometriosis three times are less likely to conceive per month of trying and why controlled ovarian stimulation with fertility drugs and/or procedures such as intrauterine insemination probably do not increase the chances of pregnancy over no treatment at all. It also explains why in vitro fertilization (which relies upon removing eggs through aspiration of the ovarian follicles before they can be affected by peritoneal toxins), by bypassing this handicap improves pregnancy rates dramatically and accordingly is the treatment of choice for most endometriosis patients with infertility.

 Ovarian Endometriomas

  Advanced endometriosis is often associated with ovarian cysts (endometriomas/chocolate cysts) that are filled with altered blood and can be large and multiple.  When these are sizable (>1cm) they can activate surrounding ovarian connective tissue causing production of excessive male hormones (androgens) such as testosterone and androstenedione. Excessive ovarian androgens can compromise egg development in the affected ovary(ies) resulting in an increased likelihood of numerical chromosomal abnormalities (aneuploidy) and reduced egg/embryo competency”. In my opinion large ovarian endometriomas need to be removed surgically or rough sclerotherapy before embarking on IVF.

The “immunologic connection”

More than two thirds of patients with endometriosis have APA’s in their blood. These antibodies, given certain conditions, are capable of attacking the embryo and preventing implantation. There are at least 21 varieties of APA. Treatment requires prior and specific identification of all 21 sub-types and their gammaglobulin isotypes. Unfortunately, only a handful of Laboratories in the United States are capable of adequately testing for APAs. But it is probably not APAs that cause infertility in endometriosis patients. Rather it is the coexistence activated NK cells (Nka) and (to a lesser extent) activated T-cells (cytotoxic lymphocytes-CTL)that attack the early embryo’s root system as soon as it tries to attach to the uterine wall that causes the problem. The presence of APAs probably represents a marker which identifies those endometriosis patients who have immunologic problems requiring immunotherapy (approximately 30% of women with endometriosis (regardless of its severity) test positive for Nka cells). Optimal treatment is predicated upon an accurate diagnosis (see below).

 How endometriosis CAN BE Diagnosed:

 Endometriosis should be suspected when symptoms such as painful menstruation (dysmenorrhea), Pain with deep penetration with intercourse (dyspareunia and painful ovulation occur in women during the 2^nd half of their reproductive lives. The diagnosis is even more probable when there is associated infertility or recurrent pregnancy (RPL). Digital pelvic examination tends to be painful because of endometriotic deposits behind the cervix or adjacent to the uterus, which is often in fixed retroversion (tilted backwards and fixed in this position because of adhesions). Sometimes the ovaries are enlarged because of c cysts filled with decomposed blood (endometriotic or “chocolate” cysts).

 Ultrasound examination is usually not helpful in diagnosing early endometriosis. However, in more severe cases, ovarian endometriomas have a characteristic appearance by ultrasound examination and can be diagnosed this way.

 A new method , known as the BCL-6 (or Receptiva) test done on an endometrial biopsy sample, if positive is highly suggestive (but not absolutely diagnostic) of underlying endometriosis and might be worth doing in cases where the diagnosis is unclear and in cases of “unexplained infertility which is often due to undiagnosed mild to moderately sever endometriosis.

In the final analysis, the diagnosis of endometriosis can only be confirmed through direct visualization of endometrial deposits at the time of pelvic surgery (laparoscopy / laparotomy) or through histopathologic microscopic analysis of affected tissue.

Note: Endometriosis can be the master of disguise. Many women with mild disease are often asymptomatic , presenting with so called “unexplained infertility”. If the endometriosis is at a very early stage, even attempted visualization (at surgery) will often fail to identify the condition. Such women, will often, upon repeat laparoscopy, reveal the condition.

 How should infertility associated with endometriosis be managed?

 The following basic concepts apply to management of endometriosis-related infertility:

• Ovulation induction with/without intrauterine insemination: Toxins in the peritoneal secretions of women with endometriosis exert a negative effect on fertilization potential regardless of how sperm reaches the fallopian tubes. It follows that intrauterine insemination will not improve the chances of pregnancy (over no treatment at all) in women with endometriosis.

• Pelvic Surgery aimed at restoring the anatomical integrity of the fallopian tubes does not counter the negative influence of toxic peritoneal factors that inherently reduce the chances of conception in women with endometriosis approximately three-fold. Nor does it address the immunologic dysfunction commonly associated with this condition. Pelvic surgery is relatively contraindicated for the treatment of infertility associated with endometriosis, when the woman is more than 35 years of age. With the pre-menopause approaching, such women do not have the time to waste on such less efficacious alternatives. In contrast, younger women who have time on their side might consider surgery as a viable option. Sizeable ovarian endometriomas should in my opinion, be removed in their entirety. Aspirating the content of such lesions is not adequate as they will return in time

• In Vitro Fertilization (IVF): Not all women who have endometriosis require IVF! However, this treatment is in my opinion, advisable in the following circumstances:

 women who have advanced endometriosis

• where surgery and prior  treatment with fertility agents and/or IUI has proven to be unsuccessful.
• Women older than 35 years and those with   diminished ovarian reserve-DOR regardless of their age)) and women with endometriosis (regardless of age)
• Women with endometriosis (regardless of its severity who have an  IID (see below)
• The role of selective immunotherapy: In about 33% of cases, endometriosis, (regardless of its severity) is associated with an immunologic implantation dysfunction (IID) linked to activation of uterine natural killer cells (NKa), cytotoxic uterine lymphocytes (CTLa) and to a much lesser extent to APA.  This is diagnosed by testing the woman’s blood for APA and for NKa using the K-562 target cell test. NKa and CTLa activation  can also be determined by endometrial biopsy for cytokine analysis. NKa/CTLa  attack the embryo’s  invading trophoblast cells (developing “root system”) as soon as begins to  attach to the uterine lining. In most cases, this results in death of the embryo even before the pregnancy is diagnosed. Sometimes it presents as a chemical pregnancy or as an early miscarriage. . As such, many women with endometriosis, rather than being infertile, in the strict sense of the word, actually experience repeated undetected “mini miscarriages”.

 Women who harbor APA’s often experience improved IVF birth rates when heparinoids (Clexane/Lovenox) are administered from the onset of ovarian stimulation with gonadotropins until the 10th week of pregnancy. NKa is treated with a combination of Intralipid (IL) and steroid therapy: Intralipid (IL) is a solution of small lipid droplets suspended in water. When administered intravenously, IL provides essential fatty acids, linoleic acid (LA), an omega-6 fatty acid, alpha-linolenic acid (ALA), an omega-3 fatty acid.IL is made up of 20% soybean oil/fatty acids (comprising linoleic acid, oleic acid, palmitic acid, linolenic acid and stearic acid) , 1.2% egg yolk phospholipids (1.2%), glycerin (2.25%)  and water (76.5%).IL exerts a modulating effect on certain immune cellular mechanisms largely by down-regulating NKa.

While the exact cause of endometriosis remains an enigma, it is now apparent that immunologic dysfunction is likely to be a significant feature of this disease. Whether immunopathology is causally linked to this condition or whether it occurs in response to endometriosis is unknown. Regardless, the underlying immunologic disorder adversely impacts on implantation of the embryo/early conceptus. It is possible, through thorough and meticulous evaluation, to quantify, typify and thereupon, selectively treat the underlying IID.. In so doing, IVF pregnancy rates can be significantly improved.

  Adenomyosis is a condition where endometrial glands, which normally line the uterus (endometrium), grow into the muscular wall of the uterus (myometrium). This can cause the uterus to become enlarged, soft, and tender.

   

  Symptoms of Adenomyosis

   

  Women with adenomyosis may experience:

  • Pelvic pain (often chronic)
  • Heavy and painful periods (menorrhagia and dysmenorrhea)
  • Pain during deep penetration during intercourse (dyspareunia)
  • Unexplained infertility or difficulty conceiving
  • Repeated miscarriages

   

  If a woman presents with these symptoms and has an enlarged, soft, and tender uterus during a pelvic exam, adenomyosis should be suspected.

   

  Diagnosing Adenomyosis

   

  Diagnosing adenomyosis can be challenging because there is no single test that confirms it definitively. However, imaging studies like MRI and ultrasound (sonogram) can provide strong evidence.

   

  Ultrasound Features Suggestive of Adenomyosis

  • Generalized enlargement of the uterus
  • Asymmetrical thickening of the myometrium (one side thicker than the other)
  • Thickened junctional zone (>12mm) with increased blood flow
  • Blurred boundary between the endometrium and myometrium
  • Cysts in the myometrium
  • Non-encapsulated tumors (adenomyomas) in the uterine muscle

   

  Adenomyosis and Infertility

   

  Adenomyosis does not directly affect egg or embryo quality, but it can cause implantation dysfunction due to changes at the endometrial-myometrial junction. Many women with adenomyosis conceive naturally, but for some, the condition can lead to infertility or recurrent pregnancy loss.

   

  Link Between Adenomyosis and Endometriosis

  • 30%–70% of women with adenomyosis also have endometriosis, a known cause of infertility.
  • Endometriosis can create a toxic pelvic environment that affects egg fertilization and implantation.
  • Women with suspected adenomyosis-related infertility should also be evaluated for endometriosis and immunologic implantation dysfunction (IID).

   

  Treatment Options for Adenomyosis

   

  Surgical Treatments

  • Conservative surgery: Removing affected portions of the uterus (adenomyomas) can help, but surgery is difficult because adenomyosis does not have clear borders.
  • Robot-assisted laparoscopic surgery is becoming more common for focal or nodular adenomyosis, as long as the disease is not widespread.

   

  Medical Treatments

   

  Three main medical treatments are used to manage adenomyosis:

  1. Hormonal Therapy (GnRH Agonists)
  • Medications like Buserelin or Lupron suppress estrogen and shrink adenomyosis lesions.
  • Commonly used as a three-month depot injection before embryo transfer in IVF.
  2. Aromatase Inhibitors (e.g., Letrozole)
  • Sometimes used, but with limited success in treating adenomyosis.
  3. Immunotherapy for Implantation Issues
  • If immunologic implantation dysfunction (IID) is suspected, treatment may include:
  • Intralipid or IVIG therapy
  • Steroids
  • Heparin (a blood thinner)
  • These treatments are often combined with IVF for women struggling with repeated implantation failure.

   

  Adenomyosis and Pregnancy

  • Not all women with adenomyosis are infertile.
  • Even with IVF, women with adenomyosis face an increased risk of miscarriage.
  • Since the condition does not affect egg or embryo quality, women with severe adenomyosis-related infertility may consider gestational surrogacy as an option.

   

  Conclusion

   

  Adenomyosis can cause pain, heavy periods, infertility, and pregnancy loss, but it does not affect egg or embryo quality. Diagnosis relies on imaging studies like MRI and ultrasound, and treatment options range from hormonal therapy and immunotherapy to surgery. Women struggling with infertility due to adenomyosis should also be evaluated for endometriosis and immune-related implantation dysfunction to determine the best treatment approach.

Very respectfully, I would not enter an FET until the cyst is gone and you have had at least one interim natural cycle. I would also strongly recommend a medicated FET.

• FROZEN EMBRYO TRANSFER : ONE PREFERRED APPROACH AT SFS.

Two decades ago, when women went through IVF (in vitro fertilization), they usually had their embryos put in the uterus right after the eggs were collected in the same cycle (known as “Fresh” Embryo Transfer). Freezing embryos at that time was risky, with about 30% not surviving the process, and those that did had lower chances of successfully implanting and growing a healthy pregnancy compared to fresh embryos. This was because the slow freezing process led to ice forming within the embryo’s cells, harming them.

But things changed with a new, faster freezing method called vitrification. With vitrification, embryos are frozen so quickly that ice crystals don’t have a chance to form. More than 90% of embryos survive this process in excellent condition, just like they were before freezing, giving them a better chance to develop into healthy pregnancies.

Modern advancements in frozen embryo transfers (FET) have shown great promise, possibly even surpassing the success rates of transferring “fresh” embryos. This improvement likely isn’t because of the freezing process itself, but rather due to two key factors:

1. a) FET often involves transferring blastocysts that have been carefully tested and selected through preimplantation genetic screening (PGS)/preimplantation genetic testing for aneuploidy ( PGT-A) , increasing the chances of a successful pregnancy compared to “fresh” transfers where such selection is not done.
2. b) The hormone replacement therapy (HRT) used for FET helps prepare the uterus optimally for implantation, improving the overall conditions for a healthy pregnancy compared to the ovarian stimulation with fertility drugs used in Fresh IVF cycles.

Considering these factors, FET offers several clear advantages:

• Safe storage of extra embryos for future transfers.
• Flexibility to delay transfers for additional testing or to avoid complications.
• Preserving embryos for selective transfer in cases of advanced maternal age or diminished ovarian reserve (DOR).
• Convenience in assisted reproductive services involving third-party parenting, like egg donation or gestational surrogacy.

These advancements provide hope and options for couples seeking successful IVF journeys and healthy outcomes for growing families.

The advent of PGS/PGT heralded a major advance in IVF as it enables us to choose the healthiest embryos for transfer to the uterus, thereby significantly boosting the chances of a successful pregnancy. The performance of PGS/PGTA virtually mandates that advanced embryos ( blastocysts) be biopsied 5-6 days after fertilization and that an additional period of 10 days be allowed for genetic testing to be performed. It follows that such blastocysts be vitrified and stored for FET to be performed in a later cycle. 

For women who are older or have a lower number of eggs (diminished ovarian reserve-DOR ), as well as those who have faced repeated pregnancy loss or IVF failure, PGS/ PGT-A can be a game-changer. It helps identify the best embryos for successful transfer. However, for younger women who tend to have normal egg reserves, and because of their youth produce a larger number of quality eggs/ embryos the benefits of PGS might not be necessary.

When it comes to creating a reserve of embryos through “Embryo Banking,” FET is mandatory and ground-breaking. Here, multiple IVF cycles are conducted over an extended period of time allowing for the collection and banking of a good number of advanced ( usually PGS/PGT-A tested)  embryos ( blastocysts) for future dispensation. Once we’ve gathered a promising group of such embryos, well-timed FETs can be undertaken, significantly improving the chances of a successful pregnancy and reducing the risk of miscarriage.

Through these advancements, we are able to offer greater  hope and possibilities to those on their journey to parenthood, making IVF an even more effective and accessible option.

Let’s break down the process to prepare the uterus for a frozen embryo transfer (FET) in simpler terms:

• Cycle Start: To begin, the recipient takes birth control pills (like Marvelon, Desogen ,Lo-Estrin etc.,)for about 10 days. The patient commences 0.75mg Dexamethasone daily OR 10mg prednisone BID at cycle start. This is continued to the 10^th week of pregnancy (tailed off from the 8^th to 10^th week) or as soon as pregnancy is ruled out
• Hormone Kickstart: After 10 days, they start another medication called Lupron/Lucrin/decapeptyl/ Superfact/ Buserelin  through a shot.
•  Monitoring Progress: The doctors keep an eye on the progress by doing ultrasounds and blood tests to make sure things are on track.
• Boosting Hormones: Delestrogen 4mg IM is injected, twice weekly (on Tuesday and Friday), commencing within a few days of Lupron/Lucrin/Superfact, Decapeptyl-induced menstruation. Blood is drawn on Monday and Thursday for measurement of blood [E2].  This allows for planned adjustment of the E2V dosage scheduled for the next day. The objective is to achieve a plasma E2 concentration of 500-1,000pg/ml and an endometrial lining of >8mm, as assessed by ultrasound examination done after 10 days of estrogen exposure i.e., a day after the 3^rd dosage of Delestrogen.  The twice weekly, final (adjusted) dosage of E2V is continued until the 10^th week of pregnancy or until  pregnancy is discounted by blood testing or by an ultrasound examination. Dexamethasone/Prednisone is  0.75 mg is taken (as above) and oral folic acid (1 mg) is taken daily commencing with the first E2V injection and is continued throughout gestation.
• Antibiotic prophylaxis: Patients also receive Ciprofloxin 500mg BID orally starting with the initiation of Progesterone therapy and continuing for 10 days.
• Luteal support: commences on day-1 , 6 days prior to the FET, with intramuscular progesterone in oil (PIO) at an initial dose of 75-100  mg (-Day 1). Daily administration- is continued until late in  the evening of Day 5 ( I suggest 10.00PM-11.00PM) . Daily PIO (75mg-100mg) is continued until the 10^th week of pregnancy, or until a blood pregnancy test/negative ultrasound (after the 6-7^th gestational week), discounts a viable pregnancy. Also, commencing on the day following the FET, the patient inserts one (1) vaginal progesterone suppository (100 mg) in the morning  + 2mg E2V vaginal suppository (in the evening) and this is continued until the 10^th week of pregnancy or until pregnancy is discounted by blood testing or by an ultrasound examination after the 6-7^th gestational week.

• Timing the  FET: This  is performed as early as possible on the morning of Day-6
• Blood pregnancy Testing:  Blood pregnancy tests are performed 13 days and 15 days after the first PIO injection was given  

*Note: In cases where intramuscular progesterone administration is not well tolerated, we tend to use a vaginal  gel known as Crinone8%. This gel is used twice a day (morning and evening) until the day of the embryo transfer.

• Preparing for Transfer: On the morning of the embryo transfer, we pause using the gel but resume it in the evening. The day after the transfer, we continue using the gel twice a day. . If the blood pregnancy tests show a positive result and 2-3 weeks later an ultrasound examination confirms a viable pregnancy, the Crinone 8%  gel is continued twice daily up to the 10th week of pregnancy

Regime for Thawing and Transferring Cryopreserved Embryos/Blastocysts:

Patients undergoing FET with cryopreserved embryos/ blastocysts will have their embryos thawed and transferred by the following regimen.

• Monitoring Pregnancy: Regular check-ups and tests are done to confirm if the pregnancy is successful.

IVF surrogacy is a remarkable process that allows individuals and couples to fulfill their dreams of parenthood, offering a path to hope and happiness. Let’s explore this transformative journey, step by step, emphasizing the positive aspects and the incredible possibilities it holds.

The Gift of Surrogacy:

 IVF surrogacy is a beautiful partnership that involves the transfer of embryos into the womb of a surrogate mother, who generously offers her womb to nurture the baby. While she doesn’t contribute genetically, her role is invaluable in helping intended parents bring their child into the world. This collaborative approach, where the intended mother provides the eggs and the father contributes the sperm, or with the help of gamete donors, has gained social acceptance, promising a brighter future for those longing for a family.

 Who Can Benefit from IVF Surrogacy:

 IVF surrogacy can be a beacon of hope for two main groups:

1. Women who, due to reasons such as a hysterectomy, disease, or a congenital absence of the uterus, cannot carry a pregnancy to full term.
2. Women advised against pregnancy due to systemic illnesses like diabetes, heart disease, or hypertension.

Comprehensive Evaluation and Support:

 Before embarking on this journey, all parties involved – the intended parents, the surrogate, and any gamete donors – undergo thorough clinical, psychological, and laboratory assessments. This ensures the well-being of everyone involved and addresses concerns such as sexually transmitted diseases, multiple gestations, miscarriages, and ectopic pregnancies. Open and honest discussions are key.

 Choosing the Right Surrogate:

 Selecting the right surrogate is a crucial step. Many couples opt for surrogacy agencies, while others turn to empathetic friends or family members to act as surrogates. It’s a heartwarming testament to the power of love and support within a community.

 Screening and Support for Surrogates:

The health and well-being of the surrogate are paramount. Extensive medical and psychological evaluations, as well as counseling, are conducted to ensure her physical and emotional readiness. When friends or family members become surrogates, it’s essential to safeguard against any coercion, especially when younger family members are involved.

 The Road to Pregnancy:

 Once the surrogate is selected and prepared, the process continues with controlled ovarian stimulation for the egg provider and hormone therapy for the surrogate. The goal is to synchronize their cycles for a successful IVF treatment.

 Preimplantation Genetic Sampling (PGS)/ Preimplantation Genetic Testing for Aneuploidy(PGT-A):

 The use of PGS through next-generation gene sequencing is a groundbreaking approach. It involves a two-part process, allowing embryos to be tested while frozen, ensuring the highest chance of success when transferred.

 Management and Follow-up:

Following the embryo transfer, the surrogate receives ongoing care and support with hormone treatments. A positive pregnancy test brings joy and optimism, and ultrasound examinations provide definitive confirmation. In the event of a negative result, hope remains as embryos can be frozen for future attempts.

Toward a Bright Future:

IVF surrogacy offers a path to parenthood filled with hope and possibility. As the field continues to evolve, the ethical guidelines will catch up. In the meantime, the focus is on collaboration and ethical practices to ensure the best outcomes for all parties involved.

 The “two-out-of-three rule” –

 —-where  two of the three essential components (egg, sperm, and gestational component) should ideally come from the intended parents – guides the journey, ensuring the best chances of success and minimizing potential challenges.

In the realm of IVF surrogacy, there’s no shortage of hope, love, and optimism. It’s a journey that transforms lives and creates families, exemplifying the incredible potential of science and compassion.

• ADDRESSING ADVANCING AGE AND DIMINISHING OVARIAN RESERVE (DOR) IN IVF

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:

1. 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.

1. 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

1. 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. Remember, knowledge is power, and being aware of these aspects empowers you to take control of your reproductive journey.

For more than 50 years, scientists have been working to perfect the art of freezing and storing a woman’s eggs, also known as “egg banking”. Although there have been challenges, the progress has been both amazing and is promising. 

Since the birth of the first “frozen egg baby” in the mid-1980s, we’ve celebrated than 6,000 -7000 births worldwide from thawed eggs. However, this is a relatively a small number when compared to the 5-6 million IVF babies and 1.5- to 2 million babies born from transferred frozen embryos during the same time.

Recently, there have been significant improvements in using frozen eggs to create embryos. Presently,  success rates are comparable to that  using frozen embryos especially when the latter have been screened for competency, using preimplantation genetic testing (PGT/ preimplantation genetic testing for aneuploidy ( PGT-A). Interestingly, currently, eggs are not screened using these techniques before they are frozen.

Let’s talk about who can benefit from this incredible advancement:

• Fertility Preservation (FP) for Women: FP is like a beacon of hope for women looking to preserve their fertility for the future. The potential demand for FP using frozen eggs is estimated to be 4-6 times higher than traditional IVF. This can be a lifeline for:
  • Women facing the possibility of losing their ovarian function due to approaching menopause, planned ovary removal, or medical treatments like radiation or chemotherapy.
  • Women planning to delay childbearing due to career aspirations, not being ready for a permanent relationship, or concerns about their biological clock.
  • Couples Opposed to Embryo Freezing: For couples who have ethical or religious concerns about freezing embryos, the option of freezing eggs brings hope and aligns with their beliefs.

As technology continues to evolve, we are moving towards a future where egg freezing is both safe, reliable, and accessible to all. It allows individuals to make informed decisions about their future and family planning. However, a word of advice: Women should consider freezing their eggs at a younger age (below 35 years) when their eggs are at their healthiest. Older women, especially those over 39, should approach this with caution as the “competency” of their eggs declines with age.

Imagine having the chance to fulfill the dream of having a family through a wonderful solution called egg banking. This amazing process involves storing healthy eggs that are later used to help women struggling with infertility to have a baby through IVF and embryo transfer.

In the United States, around 20,000 IVF procedures using donated eggs happen each year, making up about 15% of all IVF cycles. People are seeking affordable options for IVF, with many traveling abroad \for lower-cost treatments.

• Donor Egg Banks: Recently, frozen egg banks have emerged, offering access to eggs that haven’t been genetically tested. While using fresh donor eggs is a bit more successful than using frozen ones (around 40-50% versus 30-35% success rate per embryo transfer), the difference is very small . However, many frozen eggs may not survive the thawing process to become embryos, which affects the success rate. To improve success rates, most egg banks suggest buying at least six eggs at a time, each costing about $3,000.

In the United States, the cost of IVF using frozen donor eggs is high, prompting many to seek treatment in other countries ( “Medical tourism”). A significant part of this cost is associated with donor stipends and agency fees. This is why there’s a real need for a better way to access healthy donated eggs for IVF.

Conclusion:

The in vitro fertilization (IVF) market in the United States is rapidly growing and is approaching a value of $25 billion. The demand for egg banking, especially for Fertility Preservation (FP), is expected to be two to three times greater than conventional IVF. If even 10% of this potential FP market is tapped within the next five years, it could result in an annual industry worth over $3.5 billion. This shows the incredible potential of egg banking in making family dreams come true.

This amazing  journey of advancements is paving the way for new hopes and dreams. It’s about giving people choices and the power to decide when and how to shape their families. Egg banking is not just about preserving eggs; it’s about preserving dreams and the possibility of a beautiful tomorrow.
