We had an IVF cycle which ended being an ectopic. Our concern is if the tube doesn’t work to push the embryo back in uterus if it try’s to escape next cycle we have a high chance of another ectopic?
There is a chance of another ectopic but it is not inevitalde by any means.
Approximately 1 out of every 100 embryos will implant and grow outside of the uterine cavity (almost always) in a fallopian tube. This is defined as an ectopic pregnancy. Infrequently, an ectopic pregnancy attaches to an ovary or to one or more other pelvic organs. On very rare occasions (1;1,000), one twin attaches and grows in the uterine cavity with the other growing outside the uterus (i.e. a heterotopic pregnancy).
There is an ever present risk that a tubal (ectopic) pregnancy might rupture causing potentially catastrophic internal hemorrhage. Accordingly any symptoms suggesting that such bleeding has started, requires immediate confirmation of the diagnosis followed by emergency treatment.
While on rare occasions, an extrauterine (ectopic) can proceed well into pregnancy, it almost always happens prior to the 8th week. There is an increase in the incidence of ectopic pregnancy after IVF conceptions where it reportedly occurs in about 3% of cases and a woman who has had one ectopic pregnancy has almost four times as great a risk of an ectopic in a future pregnancy. In fact with every subsequent ectopic this risk of a recurrence increases dramatically.
The fertilization of the human egg normally takes place in the fallopian tube. The embryo then travels into the uterus, where it implants into the endometrial lining 5-6 days after ovulation. Anything that delays the passage of the embryo down the fallopian tube can result in the embryo hatching and sending its “root system” into the wall of the fallopian tube and initiating growth within the tube. One of the most common predisposing factors is pelvic inflammatory disease (PID) in which microorganisms, such as Chlamydia, and Gonococcus damage the inner lining (endosalpinx) and eventually also the muscular walls of the tube(s) by the formation of scar tissue. The endosalpinx has a very complex and delicate internal architecture, with small hairs and secretions that help to propel the embryo toward the uterine cavity. Once damaged, this lining can never regenerate. This is one of the reasons why women who manage to conceive following surgery to unblock fallopian tubes damaged by PID, have about a 1:4 chance of a subsequent pregnancy developing within the fallopian tube (ectopic).
Congenital malformations of the fallopian tube, associated with shortening of, or small pockets and side channels within, the tube are capable of interrupting the smooth passage of the embryo down the fallopian tube, is another cause of an ectopic pregnancy.
Since the lining of the fallopian tube does not represent an optimal site for healthy implantation, a large percentage of pregnancies that gain early attachment to its inner lining will usually be absorbed before the woman even knows that she is pregnant. This is often referred to as a tubal abortion.
The advent of advanced sonographic and hormonal monitoring technology now makes it possible to detect an ectopic pregnancy much earlier than previously, …usually well in advance of it rupturing. A decade or two ago, the diagnosis of an ectopic pregnancy, ruptured or not, was an indication for immediate laparotomy to avoid the risk of catastrophic hemorrhagic shock. This often resulted in the affected fallopian tube having to be completely removed, sometimes along with the adjacent ovary. In the late 1980’s, early conservative surgical intervention by laparoscopy began replacing laparotomy (a wide incision made in the abdominal wall) for the treatment of ectopic pregnancy, often allowing the affected fallopian tube to be preserved and shortening the period of post-surgical convalescence. In the 90’s, early detection combined with the advent of medical management with methotrexate (MTX) has all but eliminated the need for surgical intervention in the majority of patients. If administered early enough, MTX will allow spontaneous resorbtion of the pregnancy and a dramatic reduction in the incidence of catastrophic bleeding. This was especially true in ectopic pregnancies arising from In Vitro Fertilization, where the early progress of pregnancy is usually carefully monitored with hormone levels and ultrasound.
Classically women with an ectopic pregnancy present with the following symptoms:
•Missed menstrual period: Although some patients will have spotting or other abnormal bleeding. The pregnancy test will be positive in such cases.
•Vaginal bleeding. When a pregnancy inadvertently implants in the fallopian tube the lining of the uterus undergoes profound hormonal changes associated with pregnancy (primarily associated with the hormone progesterone). When the embryo dies, the lining of the uterus separates. Initially, vaginal bleeding is dark and usually is quite scanty, even less than with a normal menstrual period. In some cases, of ectopic pregnancy will bleeding is more severe, similar to that experienced in association with a miscarriage. This sometimes leads to an ectopic pregnancy initially being misdiagnosed as a miscarriage and is the reason to examine the material that is passed vaginally, for evidence of products of conception.
•Pain. In the early stages this is typically cramp-like in nature, located on one or another side of the lower abdomen. It is caused by spasm of the muscular wall of the fallopian tube(s). When a tubal pregnancy ruptures the woman will usually experience an abrupt onset of severe abdominal followed by light headedness, coldness and clamminess and will often collapse due to shock. Her pulse will become rapid and thready and her blood pressure will drop. Miscarriage. Sometimes the woman will experience pain in the right shoulder. The reason for this is that that blood which tracts along the side of the abdominal cavity finds its way to the area immediately below the diaphragm, above the liver (on the patient’s right side), irritates the endings of the phrenic nerve, which supplies that part of the diaphragm. This results in the referral of the pain to the neck and the right shoulder. The clinical picture is often so typical that making the diagnosis usually presents no difficulty at all. However, with less typical presentations the most important conditions to differentiate from an ectopic pregnancy are: a ruptured ovarian cyst, appendicitis, acute pelvic inflammatory disease (PID), or an inevitable
•Vaginal bleeding. When a pregnancy inadvertently implants in the fallopian tube the lining of the uterus undergoes profound hormonal changes associated with pregnancy (primarily associated with the hormone progesterone). When the embryo dies, the lining of the uterus separates. Initially, vaginal bleeding is dark and usually is quite scanty, even less than with a normal menstrual period. In some cases, of ectopic pregnancy will bleeding is more severe, similar to that experienced in association with a miscarriage. This sometimes leads to ectopic pregnancy initially being misdiagnosis as a miscarriage and is the reason that we often want to examine the material that is passed vaginally, for evidence of products of conception.
The easiest and most common method of diagnosing an ectopic pregnancy is by tracking the rate of rise in the blood levels of hCG. With a normal intrauterine pregnancy, these usually double every two days throughout the first few weeks. While a slow rate of increase in blood hCG usually suggests an impending miscarriage, it might also point to an ectopic pregnancy. Thus the hCG blood levels should be followed serially until a clear pattern emerges.
A vaginal ultrasound examination usually will clinch the diagnosis by showing the ectopic pregnancy within a fallopian tube and if the tube has already ruptured or internal bleeding has occurred, ultrasound examination will inevitably detect the presence of free fluid into the abdominal cavity.
If there has been a significant amount of intra-abdominal bleeding, irritation of the peritoneal membrane will cause the abdominal wall to become hard tense and, depending on the amount of internal bleeding abdominal distention will be evident. Palpation of the abdominal wall will evoke significant pain and when a vaginal examination is done, movement of the cervix will produce excruciating pain, especially on the side of the affected fallopian tube.
Surgical Treatment: In questionable situations laparoscopy is usually performed for diagnostic purposes. If an ectopic pregnancy is in fact detected, a small longitudinal incision over the tubal pregnancy will allow its removal, without necessitating removal of the tube. (linear salpingectomy). Bleeding points on the fallopian tube can usually be accessed directly and appropriately ligated (tied) via the laparoscope. Sometimes the damage to the fallopian tube has been so extensive that the entire tube will require removal.
On occasions where very severe intra-abdominal bleeding heralds a potential catastrophe, a laparotomy (an incision made to open the abdominal cavity) is performed to stop the bleeding post haste. In such cases a blood transfusion is usually required and may be life saving.
Medical Treatment: The introduction of Methotrexate (MTX) therapy for the treatment of ectopic pregnancy has profoundly reduced the need for surgery in most patients. MTX is a chemotherapeutic that kills rapidly dividing cells, such as those present in the “root system” of the conceptus. Extremely low doses of MTX are used to treat ectopic pregnancy. Accordingly the side effects that are often associated with such chemotherapy used for the treatment of other conditions are seldom seen. It is important to confirm that the ectopic pregnancy has not yet ruptured prior to administering MTX.
MTX is given by intramuscular injection. Prior to its administration, blood is drawn to get a baseline blood hCG level. After the injection of MTX the patient is allowed to return home with strict instructions that she should always have someone with her and never be alone in the ensuing week. The concern is that were the patient to be on her own and an intraabdominal bleed were to occur, she might not readily be able to access someone who could get her to the hospital immediately. Instructions are also given to look for early signs that might point towards severe intra-abdominal bleeding such as the sudden onset of severe pain, light-headedness or fainting.
The patient returns to the doctor’s office four days later to check the blood hCG level. Three days later (7 days after MTX), the level is checked again. By this time the hCG level should have dropped at least 15% from the value on day 4. If not, a second MTX injection is given and the blood levels are tested twice weekly until hCG level is undetectable. Once this occurs, vaginal bleeding will usually ensue within a week or two.
It is important to note, especially in cases where more than one embryo or blastocyst has been transferred to the uterine cavity or fallopian tube (as with Tubal embryo transfer –TET/ZIFT), that implantation may occur in two sites simultaneously (i.e. in the fallopian tube as well as inside the uterine cavity). This is referred to as a heterotopic pregnancy. It is therefore important that before administering MTX, which will cause the death and absorption of any early pregnancy, that the physician makes certain that he/she is not dealing with a heterotopic pregnancy. In such cases, surgery is required to treat the tubal ectopic, while every precaution is taken to protect the pregnancy growing within the uterine cavity.
When an ectopic pregnancy occurs following infertility treatment, there is the added advantage that the physician will be on the lookout for the earliest possible signs of trouble. The performance of a vaginal ultrasound within two weeks of a positive blood pregnancy (HCG) test following IVF allows for early detection of the unruptured pregnancy and timely intervention with MTX and/or laparoscopy.

Hi Dr Sher,
I am 44 years old and have had infertility since my mid-twenties. I lost my first pregnancy at 26 years old at 16 weeks. My first attempt at IVF was in 2013 (at 41 years old) when I had 19 eggs retrieved and only 6 fertilized. 2 were transferred and none made it to freeze. That cycle ended in a blythed ovum. In March of this year I did IVF#2 which ended in a negative (no implantation). For IVF#2 I was placed on a cocktail of supplements which included Coq10, l’argenine, Vitamin E, DHEA, Folic Acid and prescription drug Metformin (two weeks prior to beginning stimulation drugs). The cycle yielded 15 eggs, 9 of which fertilized and were described as “beautiful” by both the embryologist and my FS. 4 were transferred and 5 frozen. I am now preparing for FET in June. However, at my post cycle evaluation I was examined and told I needed to undergo a hysteroscopy to determine why my uterus was not expanding as it should. Hysteroscopy revealed I had Asherman’s Syndrome and a procedure to reduce/remove the adhesions was done and I was fitted with a balloon catheter and prescribed progynova for two weeks. Post-operation visit 2 weeks later showed that my lining had thickened to 11 mm (according to my FS, the best she has seen it since we began our IVF cycle). At transfer the lining measured 8.5mm. Dr, I am just asking your opinion on whether I would stand a good chance of implantation and a viable pregnancy based on the information I have provided here. I know my age is a huge factor.
Thank you.
Hi Julie,
respectfully, I am sure you know rthat egg and thus embryo quality (chromosomal) declines with age. So, even if the embryos/blastocysts look good microscopically, the likelihood that any such given embryo will be “competent” to propagate a viable pregnancy is no better than 1: 10. That is why at age 44Y you should preferentially be considering egg donor IVF. However, if that is not an option for you, then the only way I know of that you could have a chance with own eggs is through the banking of PGS-normal blastocysts and thereupon the selective transfer of euploid (“competent” embryos to your uterus. However, at 44y,m even more relevant is the fact that you would need a very individualized protocol for ovarian stimulation.In my opinion, . a modified, robust, long pituitary down-regulation protocol would be advisable. I would use an agonist/antagonist conversion protocol with human growth hormone (HGH) augmentation and would recommend Staggered IVF with embryo banking of PGS (next generation gene sequencing)-normal blastocysts, to make hay while the sun still shines.
As for your treated Asherman syndrome…Provided that the scar tissue is gone and you are capable of propagating a trilaminal endometrium measuring >9mm by the time of the hCG trigger or (with FET) the initiation of progesterone therapy, that should not present a problem.

How does estrace help a stimulation cycle? Thank you?
I do not prescribe oral estrace for a variety of reasons. But seen more broadly, parenteral (intramuscular) or transdermal estradiol [I prescribe parenteral estradiol valerate (Delestrogen) preferentially] can prime (enhance) response to FSH stimulation in certain candidates who have severely diminished ovarian reserve.

Dear Doctor,
I would like to share with you my first IVF experience and get your opinion. I am 38 years old, with a very regular cycle and always able to find a LH peak with ovulation tests. Further, no other tests were performed. I’ve been pregnant 3 times unfortunately the first one had to be stopped due to malformation and the other 2 ended in a early miscarriage. We have started this year with IVF and we followed a flare up protocol. On day 2 only 5 follicles were observed, and I started with decapeptyl. On day 3 and until day 14 I used decapeptyl and menopur 225. In between 6 follicles were observed to grow but at the end (day 14) only 2 were of sufficient size ( 21 en 19 mm). The extraction took place on day 16 in which 3 follicles were extracted, only 1 with an egg present. Via ICSI a top quality embryo was formed and on day 18 the transfer took place. Unfortunately I did not get pregnant. I will be having an evaluation appointment at the end of the month and I am afraid they will not want to follow given the low response I showed. I am seeking for your opinion on whether you think there might be other medications (different sorts of the ones I used) or combinations (dosages) possible that could lead to a better results. We used a flare up protocol to speed up things and because they mentioned is better in situations in which overstimulation is not a problem. I have also read that decapeptyl might be too strong in women above 35 not allowing for menopur to compensate enough to allow for a nice growing response? I will very much appreciate your opinion on this. Kindly,
Marina.
Respectfully, it sounds as if you might have developed diminished ovarian reserve (DOR) and if so, then in my opinion, using a “flare protocol” approach is less than ideal. I think the drop off from follicles to eggs as well as the quality issues could be related to the protocol chosen to stimulate your ovaries…(see below).
Doing IVF with own eggs when there is also DOR is really not a good idea. The chance of success is so low as to render egg donor-IVF by far the best option. However, when in spite the decision to use own eggs is absolutely then I would say that again, in my opinion, “microdose” (“flare”) Lupron protocols, the use of clomiphene or Letrozole, high dosage Menopur protocols and even late antagonist protocols, are best avoided because they all result in increased LH-like activity. This in turn results in increased ovarian testosterone and and this can have a deleterious effect on egg quality/competency and this is particularly the case in older women and in women of any age who have DOR. You would in my opinion need a modified, robust, long pituitary down-regulation protocol. I would use an agonist/antagonist conversion protocol with human growth hormone (HGH) augmentation and would recommend Staggered IVF with embryo banking of PGS (next generation gene sequencing)-normal blastocysts, to make hay while the sun still shines.

Dr Sher,
Do complex abnormal embryo indicate anything about the cause of the abnormality. On day three 14 all had normal cell division. By day 5-9 9 made it to blast but were complex abnormal. Is it usually the egg which is causing the problem?
The potential for a woman’s eggs to undergo orderly development and maturation, while in large part being genetically determined can be profoundly influenced by the woman’s age, her “ovarian reserve” and proximity to menopause. It is also influenced by the protocol used for controlled ovarian stimulation (COH) which by fashioning the intra-ovarian hormonal environment, profoundly impacts egg development and maturation.
After the menarche (age at which menstruation starts) a monthly process of repeatedly processing eggs continues until the menopause, by which time most eggs will have been used up, and ovulation and menstruation cease. When the number of eggs remaining in the ovaries falls below a certain threshold, ovarian function starts to wane over a 5 to10-years. This time period is referred to as the climacteric. With the onset of the climacteric, blood Follicle Stimulating Hormone (FSH) and later also Luteinizing Hormone (LH) levels begin to rise…. at first slowly and then more rapidly, ultimately culminating in the complete cessation of ovulation and menstruation (i.e. menopause).
One of the early indications that the woman has entered the climacteric and that ovarian reserve is diminishing DOR) , is the detection of a basal blood FSH level above 9.0 MIU/ml and/ or an AMH level og <2.0ng/ml.
Prior to the changes that immediately precede ovulation, virtually all human eggs have 23 pairs (i.e. 46) of chromosomes. Thirty six to forty hours prior to ovulation, a surge occurs in the release of LH by the pituitary gland. One of the main e purposes of this LH surge is to cause the chromosomes in the egg to divide n half (to 23 in number) in order that once fertilized by a mature sperm ends up having 23 chromosomes) the resulting embryo will be back to having 46 chromosomes. A “competent” mature egg is one that has precisely 23 chromosomes, not any more or any less. It is largely the egg, rather than the sperm that determines the chromosomal integrity of the embryo and only an embryo that has a normal component of 46 chromosomes (i.e. euploid) is “competent” to develop into a healthy baby. If for any reason the final number of chromosomes in the egg is less or more than 23 (aneuploid), it will be incapable of propagating a euploid, “competent” embryo. Thus egg/embryo aneuploidy (“incompetence”) is the leading cause of human reproductive dysfunction which can manifest as: arrested embryo development and/or failed implantation (which often presents as infertility), early miscarriage or chromosomal birth defects (e.g. Down’s syndrome). While most aneuploid (“incompetent”) embryos often fail to produce a pregnancy, some do. However, most such pregnancies miscarry early on. On relatively rare occasions, depending on the chromosome pair involved, aneuploid embryos can develop into chromosomally defective babies (e.g. Down’s syndrome).
Up until a woman reaches her mid- thirties, at best, 1:2 of her eggs will likely be chromosomally normal. As she ages beyond her mid-thirties there will be a a progressive decline in egg quality such that by age 40 years only about 15%-20% of eggs are euploid and, by the time the woman reaches her mid-forties, less than 10% of her eggs are likely to be chromosomally normal. While most aneuploid embryos do appear to be microscopically abnormal under the light microscope, this is not invariably so. In fact, many aneuploid embryos a have a perfectly normal appearance under the microscope. This is why it is not possible to reliably differentiate between competent and incompetent embryos on the basis of their microscopic appearance (morphologic grade) alone.
The process of natural selection usually precludes most aneuploid embryos from attaching to the uterine lining. Those that do attach usually do so for such only a brief period of time. In such cases the woman often will not even experience a postponement of menstruation. There will be a transient rise in blood hCG levels but in most cases the woman will be unaware of even having conceived (i.e. a “chemical pregnancy”). Alternatively, an aneuploid embryo might attach for a period of a few weeks before being expelled (i.e. a “miscarriage”). Sometimes (fortunately rarely) an aneuploid embryo will develop into a viable baby that is born with a chromosomal birth defect (e.g. Down’s syndrome).
The fact that the incidence of embryo aneuploidy invariably increases with advancing age serves to explain why reproductive failure (“infertility”, miscarriages and birth defects), also increases as women get older.
It is an over-simplification to represent that diminishing ovarian reserve as evidenced by raised FSH blood levels (and other tests) and reduced response to stimulation with fertility drugs is a direct cause of “poor egg/ embryo quality”. This common misconception stems from the fact that poor embryo quality (“incompetence”) often occurs in women who at the same time, because of the advent of the climacteric also have elevated basal blood FSH/LH levels and reduced AMH. But it is not the elevation in FSH or the low AMH that causes embryo “incompetence”. Rather it is the effect of advancing age (the “biological clock”) resulting a progressive increase in the incidence of egg aneuploidy, which is responsible for declining egg quality. Simply stated, as women get older “wear and tear” on their eggs increases the likelihood of egg and thus embryo aneuploidy. It just so happens that the two precipitating factors often go hand in hand.
The importance of the IVF stimulation protocol on egg/embryo quality cannot be overstated. This factor seems often to be overlooked or discounted by those IVF practitioners who use a “one-size-fits-all” approach to ovarian stimulation. My experience is that the use of individualized/customized COS protocols can greatly improve IVF outcome in patients at risk – particularly those with diminished ovarian reserve (“poor responders”) and those who are “high responders” (women with PCOS , those with dysfunctional or absent ovulation, and young women under 25 years of age).
While no one can influence underlying genetics or turn back the clock on a woman’s age, any competent IVF specialist should be able to tailor the protocol for COS to meet the individual needs of the patient.
During the normal ovulation cycle, ovarian hormonal changes are regulated to avoid irregularities in production and interaction that could adversely influence follicle development and egg quality. As an example, small amounts of androgens (male hormones such as testosterone) that are produced by the ovarian stroma (the tissue surrounding ovarian follicles) during the pre-ovulatory phase of the cycle enhance late follicle development, estrogen production by the granulosa cells (cells that line the inner walls of follicles), and egg maturation.
However, over-production of testosterone can adversely influence the same processes. It follows that protocols for controlled ovarian stimulation (COS should be geared toward optimizing follicle growth and development (without placing the woman at risk from overstimulation), while at the same time avoiding excessive ovarian androgen production. Achievement of such objectives requires a very individualized approach to choosing the protocol for COS with fertility drugs as well as the precise timing of the “trigger shot” of hCG.
It is important to recognize that the pituitary gonadotropins, LH and FSH, while both playing a pivotal role in follicle development, have different primary sites of action in the ovary. The action of FSH is mainly directed towards the cells lining the inside of the follicle that are responsible for estrogen production. LH, on the other hand, acts primarily on the ovarian stroma to produce male hormones/ androgens (e.g. androstenedione and testosterone). A small amount of testosterone is necessary for optimal estrogen production. Over-production of such androgens can have a deleterious effect on granulosa cell activity, follicle growth/development, egg maturation, fertilization potential and subsequent embryo quality. Furthermore, excessive ovarian androgens can also compromise estrogen-induced endometrial growth and development.
In conditions such as polycystic ovarian syndrome (PCOS), which is characterized by increased blood LH levels, there is also increased ovarian androgen production. It is therefore not surprising that “poor egg/embryo quality” is often a feature of this condition. The use of LH-containing preparations such as Menopur further aggravates this effect. Thus we recommend using FSH-dominant products such as Follistim, Puregon, and Gonal-F in such cases. While it would seem prudent to limit LH exposure in all cases of COS, this appears to be more vital in older women, who tend to be more sensitive to LH
It is common practice to administer gonadotropin releasing hormone agonists (GnRHa) agonists such as Lupron, and, GnRH-antagonists such as Ganirelix and Orgalutron to prevent the release of LH during COS. GnRH agonists exert their LH-lowering effect over a number of days. They act by causing an initial outpouring followed by a depletion of pituitary gonadotropins. This results in the LH level falling to low concentrations, within 4-7 days, thereby establishing a relatively “LH-free environment”. GnRH Antagonists, on the other hand, act very rapidly (within a few hours) to block pituitary LH release, so as achieve the same effect.
Long Agonist (Lupron/Buserelin) Protocols: The most commonly prescribed protocol for Lupron/gonadotropin administration is the so-called “long protocol”. Here, Lupron is given, starting a week or so prior to menstruation. This results in an initial rise in FSH and LH level, which is rapidly followed by a precipitous fall to near zero. It is followed by uterine withdrawal bleeding (menstruation), whereupon gonadotropin treatment is initiated while daily Lupron injections continue, to ensure a “low LH” environment. A modification to the long protocol which I prefer using in cases of DOR, is the Agonist/Antagonist Conversion Protocol (A/ACP) where, upon the onset of a Lupron-induced bleed , this agonist is supplanted by an antagonist (Ganirelix/Cetrotide/Orgalutron) and this is continued until the hCG trigger. In many such cases I supplement with human growth hormone (HGH) to try and further enhance response and egg development.
Lupron Flare/Micro-Flare Protocol: Another approach to COS is by way of so-called “(micro) flare protocols”. This involves initiating gonadotropin therapy simultaneous with the administration of GnRH agonist (e.g. Lupron/Buserelin). The intent here is to deliberately allow Lupron to elicit an initial surge (“flare”) in pituitary FSH release in order to augment FSH administration by increased FSH production. Unfortunately, this “spring board effect” represents “a double edged sword” because while it indeed increases the release of FSH, it at the same time causes a surge in LH release. The latter can evoke excessive ovarian stromal androgen production which could potentially compromise egg quality, especially in older women and women with PCOS, whose ovaries have increased sensitivity to LH. I am of the opinion that by evoking an exaggerated ovarian androgen response, such “(micro) flare protocols” can harm egg/embryo quality and reduce IVF success rates, especially in older women, and in women with diminished ovarian reserve. Accordingly, I do not prescribe them at all.
Estrogen Priming – My approach for “Poor Responders” Our patients who have demonstrated reduced ovarian response to COS as well as those who by way of significantly raised FSH blood levels are likely to be “poor responders”, are treated using a “modified” long protocol. The approach involves the initial administration of GnRH agonist for a number of days to cause pituitary down-regulation. Upon menstruation and confirmation by ultrasound and measurement of blood estradiol levels that adequate ovarian suppression has been achieved, the dosage of GnRH agonist is drastically lowered and the woman is given twice-weekly injections of estradiol for a period of 8. COS is thereupon initiated using a relatively high dosage of FSH-(Follistim, Bravelle, Puregon or Gonal F) which is continued along with daily administration of GnRH agonist until the “hCG trigger.” By this approach we have been able to significantly improve ovarian response to gonadotropins in many of hitherto “resistant patients”.
The “Trigger”: hCG (Profasi/Pregnyl/Novarel) versus Lupron: With ovulation induction using fertility drugs, the administration of 10,000U hCGu (the hCG “trigger”) mimics the LH surge, sending the eggs (which up to that point are immature (M1) and have 46 chromosomes) into maturational division (meiosis) This process is designed to halve the chromosome number , resulting in mature eggs (M2) that will have 23 chromosomes rather that the 46 chromosomes it had prior to the “trigger”. Such a chromosomally normal, M2 egg, upon being fertilized by mature sperm (that following maturational division also has 23 chromosomes) will hopefully propagate embryos that have 46 chromosomes and will be “:competent” to propagate viable pregnancies. The key is to trigger with no less than 10,000U of hCGu (Profasi/Novarel/Pregnyl) and if hCGr (Ovidrel) is used, to make sure that 500mcg (rather than 250mcg) is administered. In my opinion, any lesser dosage will reduce the efficiency of meiosis, and increase the risk of the eggs being chromosomally abnormal. . I also do not use the agonist (Lupron) “trigger”. This approach which is often recommended for women at risk of overstimulation, is intended to reduce the risk of OHSS. The reason for using the Lupron trigger is that by inducing a surge in the release of LH by the pituitary gland it reduces the risk of OHSS. This is true, but this comes at the expense of egg quality because the extent of the induced LH surge varies and if too little LH is released, meiosis can be compromised, thereby increasing the percentage of chromosomally abnormal and of immature (M1) eggs. The use of “coasting” in such cases (see below) can obviate this effect.
Severe Ovarian Hyperstimulation Syndrome (OHSS): Women with certain types of absent or dysfunctional ovulation as well as those who have polycystic ovarian syndrome (PCOS) are highly sensitive to gonadotropins and are at risk of developing OHSS. Such women are also more likely than others to produce poor quality eggs/embryos which, they are often led to believe is attributable to an intrinsic egg defect that is characteristic of their PCOS condition. This is not necessarily so. The most likely reason as to why many women with PCOS develop an excessive number of follicles and then go on to produce poor quality eggs/embryos has to do with the fact that, in an attempt to contain reduce the risk of OHSS they are often administered hCG prematurely – prior to the attainment of optimal egg maturation.
“Prolonged Coasting”: In the early nineties, we introduced “Prolonged Coasting”, a procedure which eliminates the risk of OHSS while allowing the hCG trigger to be deferred for long enough as to allow for optimal follicle/egg maturation to take place. Coasting involves withholding gonadotropin therapy while the administration of GnRH agonist/antagonist is continued. The daily measurement of blood estradiol is continued until the concentration drops below a safe threshold level, at which time HCG is administered (regardless of the number of follicles). When appropriately implemented “coasting” results in the production of good quality eggs/embryos, in circumstances where this might otherwise not have been possible.
