I know of no medical announcement associated with the degree of emotional anticipation and anguish as that associated with a pending diagnosis/confirmation of pregnancy following infertility treatment. In fact, hardly a day goes by where I am not confronted by a patient anxiously seeking interpretation of a pregnancy test result.

Testing urine or blood for the presence of human chorionic gonadotropin (hCG) is the most effective and reliable way to confirm conception. The former, is far less expensive than the latter and is the most common method used. It is also more convenient because it can be performed in the convenience of the home setting. However, urine hCG testing for pregnancy is not nearly as reliable or as sensitive e as is blood hCG testing. Blood testing can detect implantation several days earlier than can a urine test. Modern pregnancy urine test kits can detect hCG about 16-18 days following ovulation (or 2-3 days after having missed a menstrual period), while blood tests can detect hCG, 12-13 days post-ovulation (i.e. even prior to menstruation).

The ability to detect hCG in the blood as early as possible and thereupon to track its increase, is particularly valuable in women undergoing controlled ovarian stimulation (COS) with or without intrauterine insemination (IUI) or after IVF. The earlier hCG can be detected in the blood and its concentration measured, the sooner levels can be tracked serially over time and so provide valuable information about the effectiveness of implantation, and the potential viability of the developing conceptus.

There are a few important points that should be considered when it comes to measuring interpreting blood hCG levels. These include the following:

• All modern day blood (and urine) hCG tests are highly specific in that they measure exclusively for hCG. There is in fact no cross-reactivity with other hormones such as estrogen, progesterone or LH.
• Post conception hCG levels, measured 10 days post ovulation or egg retrieval can vary widely (ranging from 5mIU/ml to above 400mIU/ml. The level will double every 48–72 hours up to the 6th week of gestation whereupon the doubling rate starts to slow down to about 96 hours. An hCG level of 13,000-290, 0000 mIU/ml is reached by the end of the 1st trimester (12 weeks) whereupon it slowly declines to approximately 26,000– 300,000 mIU/ml by full term. Below are the average hCG levels during the first trimester:

• • 3 weeks LMP: 5 – 50 mIU/ml
  • 4 weeks LMP: 5 – 426 mIU/ml
  • 5 weeks LMP: 18 – 7,340 mIU/ml
  • 6 weeks LMP: 1,080 – 56,500 mIU/ml
  • 7 – 8 weeks LMP: 7, 650 – 229,000 mIU/ml
  • 9 – 12 weeks LMP: 25,700 – 288,000 mIU/ml

• A single hCG blood level is not sufficient to assess the viability of an implanting embryo. Caution should be used in making too much of an initial hCG level. This is because a normal pregnancy can start with relatively low hCG blood levels. It is the rate of the rise of the blood hCG level that is relevant.
• In some cases the initially hCG level is within the normal range, but then fails to double in the ensuing 48-72hours. In some cases it might even plateau or decline, only to start doubling appropriately thereafter. When this happens, it could be due to:
  • A recovering implantation, destined to develop into a clinical gestation
  • A failing implantation (a chemical pregnancy)
  • A multiple pregnancy which is spontaneously reducing (i.e., one or more of the concepti is being lost) or,
  • An ectopic pregnancy which will either absorb spontaneously (a chemical-tubal gestation), or evolve into a full blown tubal pregnancy continue and declare itself through characteristic symptoms and signs of an intraperitoneal bleed.
• The blood hCG test needs to be repeated at least once after 48h and in some cases it will need to be repeated one or more times (at 48h intervals) thereafter, to confirm that implantation is progressing normally.
• Ultimately the diagnosis of a viable pregnancy requires confirmation of the presence of an intrauterine gestational sac by ultrasound examination. The earliest that this can be achieved is when the beta hCG level exceeds 1,000mIU/ml (i.e., around 5-6 weeks).
• Most physicians prefer to defer the performance of a routine US diagnosis of pregnancy until closer to the 7th week. This is because by that time, cardiac activity should be clearly detectable, allowing for more reliable assessment of pregnancy viability.
• There are cases where the blood beta hCG level is extraordinarily high or the rate of rise is well above the normal doubling rate. The commonest explanation is that more than one pregnancy has implanted. However in some cases it can point to a molar pregnancy
• Finally, there on rare occasions, conditions unrelated to pregnancy can result in detectable hCG levels in blood and urine. They include ovarian tumors that produce hCG, such as certain types of cystic teratomas (dermoid cysts) and some ovarian cancers such as dysgerminomas.

WE should talk! Feel free to call my assistant Patti Converse  to set up an onloine consultation.

Whenever a patient fails to achieve a viable pregnancy following embryo transfer (ET), the first question asked is why! Was it simply due to, bad luck?, How likely is the failure to recur in future attempts and what can be done differently, to avoid it happening next time?.

It is an indisputable fact that any IVF procedure is at least as likely to fail as it is to succeed. Thus when it comes to outcome, luck is an undeniable factor. Notwithstanding, it is incumbent upon the treating physician to carefully consider and address the causes of IVF failure before proceeding to another attempt:

1. Age: The chance of a woman under 35Y of age having a baby per embryo transfer is about 35-40%. From there it declines progressively to under 5% by the time she reaches her mid-forties. This is largely due to declining chromosomal integrity of the eggs with advancing age…”a wear and tear effect” on eggs that are in the ovaries from birth.
2. Embryo Quality/”competency (capable of propagating a viable pregnancy)”. As stated, the woman’s age plays a big role in determining egg/embryo quality/”competency”. This having been said, aside from age the protocol used for controlled ovarian stimulation (COS) is the next most important factor. It is especially important when it comes to older women, and women with diminished ovarian reserve (DOR) where it becomes essential to be aggressive, and to customize and individualize the ovarian stimulation protocol.

 We used to believe that the uterine environment is more beneficial to embryo development than is the incubator/petri dish and that accordingly, the earlier on in development that embryos are transferred to the uterus, the better. To achieve this goal, we used to select embryos for transfer based upon their day two or microscopic appearance (“grade”).  But we have since learned that the further an embryo has advanced in its development, the more likely it is to be “competent” and that embryos failing to reach the expanded blastocyst stage within 5-6 days of being fertilized are almost invariably “incompetent” and are unworthy of being transferred. Moreover, the introduction into clinical practice about 15y ago, (by Levent Keskintepe PhD and myself) of Preimplantation Genetic Sampling (PGS), which assesses for the presence of all the embryos chromosomes (complete chromosomal karyotyping), provides another tool by which to select the most “competent” embryos for transfer. This methodology has selective benefit when it comes to older women, women with DOR, cases of unexplained repeated IVF failure and women who experience recurrent pregnancy loss (RPL).

1. The number of the embryos transferred: Most patients believe that the more embryos transferred the greater the chance of success. To some extent this might be true, but if the problem lies with the use of a suboptimal COS protocol, transferring more embryos at a time won’t improve the chance of success. Nor will the transfer of a greater number of embryos solve an underlying embryo implantation dysfunction (anatomical molecular or immunologic).Moreover, the transfer of multiple embryos, should they implant, can and all too often does result in triplets or greater (high order multiples) which increases the incidence of maternal pregnancy-induced complications and of premature delivery with its serious risks to the newborn. It is for this reason that I rarely recommend the transfer of more than 2 embryos at a time and am moving in the direction of advising single embryo transfers …especially when it comes to transferring embryos derived through the fertilization of eggs from young women.

1. Implantation Dysfunction (ID): Implantation dysfunction is a very common (often overlooked) cause of “unexplained” IVF failure. This is especially the case in young ovulating women who have normal ovarian reserve and have fertile partners. Failure to identify, typify, and address such issues is, in my opinion, an unfortunate and relatively common cause of repeated IVF failure in such women. Common sense dictates that if ultrasound guided embryo transfer is performed competently and yet repeated IVF attempts fail to propagate a viable pregnancy, implantation dysfunction must be seriously considered. Yet ID is probably the most overlooked factor. The most common causes of implantation dysfunction are:

1. A“ thin uterine lining”
2. A uterus with surface lesions in the cavity (polyps, fibroids, scar tissue)
3. Immunologic implantation dysfunction (IID)
4. Endocrine/molecular endometrial receptivity issues
5. Ureaplasma Urealyticum (UU) Infection of cervical mucous and the endometrial lining of the uterus, can sometimes present as unexplained early pregnancy loss or unexplained failure following intrauterine insemination or IVF. The infection can also occur in the man, (prostatitis) and thus can go back and forth between partners, with sexual intercourse. This is the reason why both partners must be tested and if positive, should be treated contemporaneously.

Certain causes of infertility are repetitive and thus cannot readily be reversed. Examples include advanced age of the woman; severe male infertility; immunologic infertility associated with alloimmune implantation dysfunction (especially if it is a “complete DQ alpha genetic match between partners plus uterine natural killer cell activation (NKa).

ADENOMYOSIS:

Adenomyosis is a condition where endometrial glands develop outside the uterine lining (endometrium), within the muscular wall of the uterus (myometrium). Definitive diagnosis of adenomyosis is difficult to make. The condition should be suspected when a premenopausal woman (usually>25 years of age) presents with pelvic pain, heavy painful periods, pain with deep penetration during intercourse, “unexplained infertility” or repeated miscarriages and thereupon, when on digital pelvic examination she is found to have an often smoothly enlarged (bulky) soft tender uterus. Previously, a definitive diagnosis was only possible after a woman had her uterus removed (hysterectomy) and it this was inspected under a microscope. However the use of uterine magnetic resonance imaging (MRI) now permits reliable diagnosis. Ultrasound examination of the uterus on the other hand , while not permitting definitive diagnosis, is a very helpful tool in raising a suspicion of the existence of adenomyosis.

Criteria used to make a diagnosis of adenomyosis on transvaginal ultrasound:

• Smooth generalized enlargement of the uterus.
• Asymmetrical thickening of one side of the (myometrium) as compared to another side.
• Thickening (>12mm) of the junctional zone between the endometrium and myometrium with increased blood flow.
• Absence of a clear line of demarcation between the endometrium and the myometrium
• Cysts in the myometrium
• One or more non discrete (not encapsulated) tumors (adenomyomas) in the myometrium.

 Since there is no proven independent relationship between adenomyosis and egg/embryo quality any associated reproductive dysfunction (infertility/miscarriages) might be attributable to an implantation dysfunction. It is tempting to postulate that this is brought about by adenomyosis-related anatomical pathology at the endometrial-myometrial junction. However, many women with adenomyosis, do go on to have children without difficulty. Given that 30%-70% of women who have adenomyosis also have endometriosis…. a known cause of infertility, it is my opinion that infertility caused by adenomyosis is likely linked to endometriosis where infertility is at least in part due to a toxic pelvic environment that compromises egg fertilization potential and/or due to an immunologic implantation dysfunction (IID) linked to activation of uterine natural killer cells (NKa). Thus, in my opinion all women who are suspected of having adenomyosis-related reproductive dysfunction (infertility/miscarriages) should be investigated for endometriosis and for IID. The latter, if confirmed would make them candidates for selective immunotherapy (using intralipid/steroid/heparin) in combination with IVF.

Surgery: Conservative surgery to address adenomyosis-related infertility involves excision of portions of the uterus with focal or nodular adenomyosis and/or excision of uterine adenomyomas. It is very challenging and difficult to perform because adenomyosis does not have distinct borders that distinguish normal uterine tissue from the lesions. In addition, surgical treatment for adenomyosis-related reproductive dysfunction is of questionable value and of course is  not an option for diffuse adenomyosis.

Medical treatment: There are three approaches.

• GnRH agonists (Buserelin/Lupron) which is thought to work by lowering estrogen levels.
• Aromatase inhibitors such as Letrozole have also been tried with limited success
• Inhibitors of angiogenesis: The junctional zone in women with adenomyosis may grow blood vessels more readily that other women (i.e. angiogenesis). A hormone known as VEGF can drive this process. It is against this background that it has been postulated that use of drugs that reduce the action of VEGF and thereby counter blood vessel proliferation in the uterus could have a therapeutic benefit. While worth trying in some cases, thus far such treatment has been rather disappointing
• Immunotherapy to counter IID: The use of therapies such as Intralipid (or IVIG)/steroids/heparin in combination with IVF might well hold promise in those women with adenomyosis who have NKa.

Fortunately, not all women with adenomyosis are infertile. For those who are, treatment presents a real problem. Even when IVF is used and the woman conceives, there is still a significant risk of miscarriage. Since the condition does not compromise egg/embryo quality, women with adenomyosis-related intractable reproductive dysfunction who fail to benefit from all options referred to above…(including IVF) might as a last resort consider  Gestational surrogacy.

Damage to the Fallopian tubes as a result of prior pelvic inflammation is one of the most common female causes of infertility. Commonly (as was the case with RL), this results blockage of the tubes at their ends, while leaving them open and  connected to the uterine cavity. In such cases the Fallopian tubes often progressively fill with fluid (hydrosalpinx), distending that contains dead cells and other noxious products….potentially toxic to embryos. Leakage of such fluid back wards into the uterus can severely compromise implantation of transferred embryos. This is why women with hydrosalpinges are strongly advised to have such diseased tubes removed or ligated (at the point that they emerge from the uterine wall), prior to undergoing embryo transfer. Admittedly, it is often hard for patients to accept that their tubes will be gone, as it means that future conception will require IVF. This is where it is necessary to be explain that  such tubes are functionless and that even if they could be rendered patent (opened) through surgery, the likelihood of pregnancy occurring would be remote.

Women with tubal occlusion who want to have a baby, will  invariably require IVF. In many such cases one or both of their tubes will, over time, have progressively filled with toxic fluid that can drain back into the uterine cavity and thwart post-ET implantation. It follows that all cases of tubal blockage be careful evaluated for hydrosalpinges before ET and that when detected,  this first  be  surgically addressed through tubal ligation or removal (salpingectomy).

Prolactin is a protein hormone (closely related to human growth hormone) that is secreted by specialized cells in the anterior part of the pituitary gland. In addition, the hormone is also produced and secreted by a broad range of other cells in the body, most prominently various immune cells, the brain and the lining of the uterus. Most cells respond to prolactin. In fact, it is hard to identify any tissue that does not have prolactin receptors.

Although prolactin’s major target organ is the breast where it stimulates development and milk production, the hormone has many other functions. Several hundred different actions have been reported for prolactin and

Immune cells are rich in prolactin receptors and certain types of lymphocytes in fact synthesize and secrete prolactin. These observations suggest that prolactin may to some extent act as a regulator of the body’s immune activity.

In an area in the brain known as the hypothalamus, a chemical called dopamine is released. Dopamine suppresses prolactin synthesis and release by the pituitary gland. As such it acts as a “hypothalamic brake set” causing prolactin only to be secreted when the “brake” is released. Treatment with dopamine agonists such as bromocriptine (Parlodel) and cabergoline (Dostinex) , by enhancing serotonin production lowers prolactin

Several other hypothalamic hormones, including thyroid releasing hormone (TRH) and gonadotropin releasing hormone (GnRH) cause an increase in prolactin secretion Stimulation of the nipples (including but not limited to nursing) leads to hypothalamic activation and prolactin release Estrogens also exerts a positive control over prolactin synthesis and secretion

Even modestly raised prolactin levels (20ng/ml-40ng/ml) can interfere with estrogen-induced endometrial proliferation as well as egg/ ovarian follicle growth and development. Accordingly treatment with dopamine agonists (bromocriptine/ Cabergoline) might be of benefit in such cases.

Increased PRL secretion reduces the pulsatility of GnRH impairing the pituitary production of FSH and LH and may directly impair the endocrine activity of ovarian follicles as well as endometrial response to estrogen. This can lead to dysfunctional or failed ovulation, a defective luteal phase, and a poorly developed endometrial response to estrogen (a thin endometrial lining). About n 5% of unselected, asymptomatic infertile women have hyperprolactinemia. In such cases long-term use of dopaminergic drugs such as bromocryptine and can normalized prolactin levels leading to reestablishment of functional ovulation and improved endometrial development. About half of the pregnancies occurring during dopaminergic therapy start after the first 6 months of this drug therapy. Treatment should continue for at least 1 year.

Common manifestations of significantly increased prolactin secretion (hyperprolactinemia):

• In women:
  • Oligo/amenorrhea (reduction or absence of menstrual flow) and galactorrhea (excessive or spontaneous breast secretion of milk).
  • A modest elevation in blood prolactin can also point to an underlying state of hypothyroidism
  • Markedly elevated prolactin levels (i.e. >60ng/ml) might point to a prolactin producing pituitary macroadenoma or microadenoma as well as other intracranial lesions such as craniopharyngiomas, meningiomas etc.
• In men: Such men rarely have galactorrhea
  • Hypogonadism,
  • Breast enlargement (gynecomastia)
  • Erectile dysfunction
  • Decreased Libido
  • Sperm dysfunction resulting in infertility and with impotence.

Causes of hyperprolactinemia: Main causes of pathologic hyperprolactinemia (40).

• Idiopathic (commonest variety) ….cause unknown Acromegaly
• Empty Sella Turcica
• Renal Failure
• Polycystic Ovarian Syndrome (PCOS)
• Certain drugs:
  • Antipsychotic drugs ( phenothiazines, haloperidol, monoamine oxidases (MAO) risperidone, fluoxetine, butyrophenones,
  • Anti-emetics: metoclopramide, domperidone,
  • Tricyclic antidepressants
  • Opiates
  • Verapamil
  • Antihypertensives and Ganglion blockers

Drug-induced hyperprolactinemia can be reversed by modifying or withdrawing the causative medication. In cases where this cannot safely be done, bromocryptine derivatives can be used.

• Pituitary adenomas (prolactinomas)
  •  Some pituitary adenomas are treated by surgical removal but in most case prolonged treatment with bromocryptine or cabergoline will effectively lower blood concentrations and lead to shrinkage/disappearance of the tumor. Such treatment is also safe during pregnancy.
  •  Intracranial lesions such as craniopharyngiomas, meningioma causing hyperprolactinemia are usually treated by surgical removal.

Hyperprolactinemia and Reproductive Dysfunction:

• Hypothyroidism in women is often caused by an autoimmune process where antithyroid antibodies progressively replace thyroid glandular tissue with functionless connective tissue. In roughly 50% of such cases there will be increased uterine natural killer cell activity (NKa) which may profoundly impair implantation leading to “perceived infertility” or recurrent pregnancy loss. Thus, ATA with NKa can be present prior to the development of clinically overt autoimmune hypothyroidism (Hashimoto’s disease). Since women with NKa are often infertile, or experience recurrent pregnancy loss, it is important that any unexplained hyperprolactinemia associated with reproductive failure or infertility be evaluated for an immunologic implantation dysfunction (IID) through testing  for the presence of antithyroid antibodies and if the ATA level is elevated, that an NKa test (K-562 target cell test) be done. What is not often commonly recognized is that even in cases where autoimmune hypothyroidism is clinically overt, treatment with thyroid hormone replacement will usually not solve the reproductive dysfunction which will usually require selective immunotherapy with Intralipid (IL) infusions plus steroid therapy. IL is administered intravenously about 4-7 days prior to ovulation or egg retrieval and then repeated one more time upon biochemical confirmation of early pregnancy. The steroids are continued to the 8^th  week of pregnancy and then tailed off over 2 weeks.

• Ovarian Hyperstimulation Syndrome (OHS): Prolactin facilitates production by ovarian follicle cells of VEGF (a vasoactive substance that increases vascular permeability of blood vessels) In cases of severe ovarian With severe ovarian hyperstimulation syndrome (OHSS) where there are a large number of follicles present (>25) and the blood estradiol level is markedly elevated (4,000pg/ml), even modestly elevated prolactin release can markedly worsen the situation. There is strong evidence to suggest that women with ovarian Hyperstimulation (>20 follicles and blood estradiol levels that peak above 3,000pg/ml) who receive O.5mg of oral administration Cabergoline daily for 7 days, starting on the day of the hCG trigger, experience a significant reduction in the risk and severity of severe ovarian stimulation syndrome (OHSS). This is thought to be due to Cabergoline suppressing the production of vascular vasoactive substances such as VEGF that are produced by luteinized follicular granulosa cells, that increase the vascular permeability of local pelvic blood vessels.
