Hi Dr Sher,
I’m 11w3days pregnant and have been taking 20mg of prednisone since before transfer. My doctor is going to start weening me off. Out of interest, what would be your weening off protocol for 20mg prednisone? 10mg then 5mg?
Thanks as always!
Yes! That would be appropriate.

Hi Dr. Sher,
Wondering if you have any suggestions on our case, our poor fertilization rate, our protocol and/ or next steps.
Brief history:
– I just turned 40
-I had first child with my husband in 2014 (at 34); fell pregnant very quickly and easy pregnancy, except for c-section due to breech baby
– I had second child with my husband 23 months later, in 2016 at age 36 (again, so pregnant very easily and very easy pregnancy, v-bac)
-I fell pregnant again within first month of trying for third child in early 2018, at 37 (almost 38) but miscarried at 14 weeks, after seeing heartbeat etc. (no previous miscarriages)
– since then have had 7 consecutive miscarriages (ranging from 5 week miscarriages to 12 week miscarriages), all with my husband (same partner). I get pregnant very very quickly but then lose the pregnancy time and time again now; testing of products of conception has shown 2 of these miscarriages were trisomies
– have had all the standard recurrent loss work ups at recurrent loss clinic in Vancouver, Canada
– decided to try ivf with PGT testing after my last miscarriage in May of this year
– 1st cycle in June/July 2020: estrace priming month followed by 225 puregon/225 Menopur for 9.5 days; this produced 16 eggs (15 mature) but only 4 fertilized by natural fertilization (and of those only 2 for testing, resulting in 1 abnormal and 1 mosaic)
-2nd cycle this September 2020 (back to back with first cycle): Same protocol: again, priming month with estrace followed by 225 puregon and 225 Menopur for 11.5 days; this produced 18 eggs (17 mature); used ICSI hoping for better fertilization, but of the 18, only 9 fertilized.
Wondering if the bad fertilization rates were are seeing, with of without ICSI, is just purely an age issue for me. I seem to respond very well to drugs and produce lots of eggs. I also have never had trouble getting pregnant. Could it be that I am very fertile but with all bad eggs (despite me having 2 kids relatively recently and with ease)? Could my protocol somehow be affecting fertilization rate? Any links that can be drawn between my ivf results and my history of recurrent losses?
Any advice is greatly appreciated.

Although it is true that age and diminishing ovarian reserve (DOR) have a detrimental effect on egg quality and that sporadic miscarriages are more often than not due to embryo “incompetency”, this general rule does not apply when the miscurriaged are recurrent. In such cases, the cause is more likely to be an implantation dysfunction. Accordingly, I believe it to be far more likely that you have developed an anatomical or immunologic implantation dysfunction (IID):
When it comes to reproduction, humans are the poorest performers of all mammals. In fact we are so inefficient that up to 75% of fertilized eggs do not produce live births, and up to 30% of pregnancies end up being lost within 10 weeks of conception (in the first trimester). RPL is defined as two (2) or more failed pregnancies. Less than 5% of women will experience two (2) consecutive miscarriages, and only 1% experience three or more.
Pregnancy loss can be classified by the stage of pregnancy when the loss occurs:
•Early pregnancy loss (first trimester)
•Late pregnancy loss (after the first trimester)
•Occult “hidden” and not clinically recognized, (chemical) pregnancy loss (occurs prior to ultrasound confirmation of pregnancy)
•Early pregnancy losses usually occur sporadically (are not repetitive).
In more than 70% of cases the loss is due to embryo aneuploidy (where there are more or less than the normal quota of 46 chromosomes). Conversely, repeated losses (RPL), with isolated exceptions where the cause is structural (e.g., unbalanced translocations), are seldom attributable to numerical chromosomal abnormalities (aneuploidy). In fact, the vast majority of cases of RPL are attributable to non-chromosomal causes such as anatomical uterine abnormalities or Immunologic Implantation Dysfunction (IID).
Since most sporadic early pregnancy losses are induced by chromosomal factors and thus are non-repetitive, having had a single miscarriage the likelihood of a second one occurring is no greater than average. However, once having had two losses the chance of a third one occurring is double (35-40%) and after having had three losses the chance of a fourth miscarriage increases to about 60%. The reason for this is that the more miscarriages a woman has, the greater is the likelihood of this being due to a non-chromosomal (repetitive) cause such as IID. It follows that if numerical chromosomal analysis (karyotyping) of embryonic/fetal products derived from a miscarriage tests karyotypically normal, then by a process of elimination, there would be a strong likelihood of a miscarriage repeating in subsequent pregnancies and one would not have to wait for the disaster to recur before taking action. This is precisely why we strongly advocate that all miscarriage specimens be karyotyped.
There is however one caveat to be taken into consideration. That is that the laboratory performing the karyotyping might unwittingly be testing the mother’s cells rather than that of the conceptus. That is why it is not possible to confidently exclude aneuploidy in cases where karyotyping of products suggests a “chromosomally normal” (euploid) female.
Late pregnancy losses (occurring after completion of the 1st trimester/12th week) occur far less frequently (1%) than early pregnancy losses. They are most commonly due to anatomical abnormalities of the uterus and/or cervix. Weakness of the neck of the cervix rendering it able to act as an effective valve that retains the pregnancy (i.e., cervical incompetence) is in fact one of the commonest causes of late pregnancy loss. So also are developmental (congenital) abnormalities of the uterus (e.g., a uterine septum) and uterine fibroid tumors. In some cases intrauterine growth retardation, premature separation of the placenta (placental abruption), premature rupture of the membranes and premature labor can also causes of late pregnancy loss.
Much progress has been made in understanding the mechanisms involved in RPL. There are two broad categories:
1.Problems involving the uterine environment in which a normal embryo is prohibited from properly implanting and developing. Possible causes include:
•Inadequate thickening of the uterine lining
•Irregularity in the contour of the uterine cavity (polyps, fibroid tumors in the uterine wall, intra-uterine scarring and adenomyosis)
•Hormonal imbalances (progesterone deficiency or luteal phase defects). This most commonly results in occult RPL.
•Deficient blood flow to the uterine lining (thin uterine lining).
•Immunologic implantation dysfunction (IID). A major cause of RPL. Plays a role in 75% of cases where chromosomally normal preimplantation embryos fail to implant.
•Interference of blood supply to the developing conceptus can occur due to a hereditary clotting disorder known as Thrombophilia.
2.Genetic and/or structural chromosomal abnormality of the embryo.Genetic abnormalities are rare causes of RPL. Structural chromosomal abnormalities are slightly more common but are also occur infrequently (1%). These are referred to as unbalanced translocation and they result from part of one chromosome detaching and then fusing with another chromosome. Additionally, a number of studies suggest the existence of paternal (sperm derived) effect on human embryo quality and pregnancy outcome that are not reflected as a chromosomal abnormality. Damaged sperm DNA can have a negative impact on fetal development and present clinically as occult or early clinical miscarriage. The Sperm Chromatin Structure Assay (SCSA) which measures the same endpoints are newer and possibly improved methods for evaluating.
IMMUNOLOGIC IMPLANTATION DYSFUNCTION
Autoimmune IID: Here an immunologic reaction is produced by the individual to his/her body’s own cellular components. The most common antibodies that form in such situations are APA and antithyroid antibodies (ATA).
But it is only when specialized immune cells in the uterine lining, known as cytotoxic lymphocytes (CTL) and natural killer (NK) cells, become activated and start to release an excessive/disproportionate amount of TH-1 cytokines that attack the root system of the embryo, that implantation potential is jeopardized. Diagnosis of such activation requires highly specialized blood test for cytokine activity that can only be performed by a handful of reproductive immunology reference laboratories in the United States.
Alloimmune IID, i.e., where antibodies are formed against antigens derived from another member of the same species, is believed to be a relatively common immunologic cause of recurrent pregnancy loss.
Autoimmune IID is often genetically transmitted. Thus it should not be surprising to learn that it is more likely to exist in women who have a family (or personal) history of primary autoimmune diseases such as lupus erythematosus (LE), scleroderma or autoimmune hypothyroidism (Hashimoto’s disease), autoimmune hyperthyroidism (Grave’s disease), rheumatoid arthritis, etc. Reactionary (secondary) autoimmunity can occur in conjunction with any medical condition associated with widespread tissue damage. One such gynecologic condition is endometriosis. Since autoimmune IID is usually associated with activated NK and T-cells from the outset, it usually results in such very early destruction of the embryo’s root system that the patient does not even recognize that she is pregnant. Accordingly the condition usually presents as “unexplained infertility” or “unexplained IVF failure” rather than as a miscarriage.
Alloimmune IID, on the other hand, usually starts off presenting as unexplained miscarriages (often manifesting as RPL). Over time as NK/T cell activation builds and eventually becomes permanently established the patient often goes from RPL to “infertility” due to failed implantation. RPL is more commonly the consequence of alloimmune rather than autoimmune implantation dysfunction.
However, regardless, of whether miscarriage is due to autoimmune or alloimmune implantation dysfunction the final blow to the pregnancy is the result of activated NK cells and CTL in the uterine lining that damage the developing embryo’s “root system” (trophoblast) so that it can no longer sustain the growing conceptus. This having been said, it is important to note that autoimmune IID is readily amenable to reversal through timely, appropriately administered, selective immunotherapy, and alloimmune IID is not. It is much more difficult to treat successfully, even with the use of immunotherapy. In fact, in some cases the only solution will be to revert to selective immunotherapy plus using donor sperm (provided there is no “match” between the donor’s DQa profile and that of the female recipient) or alternatively to resort to gestational surrogacy.
DIAGNOSING THE CAUSE OF RPL
In the past, women who miscarried were not evaluated thoroughly until they had lost several pregnancies in a row. This was because sporadic miscarriages are most commonly the result of embryo numerical chromosomal irregularities (aneuploidy) and thus not treatable. However, a consecutive series of miscarriages points to a repetitive cause that is non-chromosomal and is potentially remediable. Since RPL is most commonly due to a uterine pathology or immunologic causes that are potentially treatable, it follows that early chromosomal evaluation of products of conception could point to a potentially treatable situation. Thus I strongly recommend that such testing be done in most cases of miscarriage. Doing so will avoid a great deal of unnecessary heartache for many patients.
Establishing the correct diagnosis is the first step toward determining effective treatment for couples with RPL. It results from a problem within the pregnancy itself or within the uterine environment where the pregnancy implants and grows. Diagnostic tests useful in identifying individuals at greater risk for a problem within the pregnancy itself include:
Karyotyping (chromosome analysis) both prospective parents
•Assessment of the karyotype of products of conception derived from previous miscarriage specimens
•Ultrasound examination of the uterine cavity after sterile water is injected or sonohysterogram, fluid ultrasound, etc.)
•Hysterosalpingogram (dye X-ray test)
•Hysteroscopic evaluation of the uterine cavity
•Full hormonal evaluation (estrogen, progesterone, adrenal steroid hormones, thyroid hormones, FSH/LH, etc.)
•Immunologic testing to include:
a)Antiphospholipid antibody (APA) panel
b)Antinuclear antibody (ANA) panel
c)Antithyroid antibody panel (i.e., antithyroglobulin and antimicrosomal antibodies)
d)Reproductive immunophenotype
e)Natural killer cell activity (NKa) assay (i.e., K562 target cell test)
f)Alloimmune testing of both the male and female partners
TREATMENT OF RPL
Treatment for Anatomic Abnormalities of the Uterus: This involves restoration through removal of local lesions such as fibroids, scar tissue, and endometrial polyps or timely insertion of a cervical cerclage (a stitch placed around the neck of the weakened cervix) or the excision of a uterine septum when indicated.
Treatment of Thin Uterine Lining: A thin uterine lining has been shown to correlate with compromised pregnancy outcome. Often this will be associated with reduced blood flow to the endometrium. Such decreased blood flow to the uterus can be improved through treatment with sildenafil and possibly aspirin.
Sildenafil (Viagra) Therapy. Viagra has been used successfully to increase uterine blood flow. However, to be effective it must be administered starting as soon as the period stops up until the day of ovulation and it must be administered vaginally (not orally). Viagra in the form of vaginal suppositories given in the dosage of 25 mg four times a day has been shown to increase uterine blood flow as well as thickness of the uterine lining. To date, we have seen significant improvement of the thickness of the uterine lining in about 70% of women treated. Successful pregnancy resulted in 42% of women who responded to the Viagra. It should be remembered that most of these women had previously experienced repeated IVF failures.
Use of Aspirin: This is an anti-prostaglandin that improves blood flow to the endometrium. It is administered at a dosage of 81 mg orally, daily from the beginning of the cycle until ovulation.
Treating Immunologic Implantation Dysfunction with Selective Immunotherapy: Modalities such as IL/IVIg, heparinoids (Lovenox/Clexane), and corticosteroids (dexamethasone, prednisone, prednisolone) can be used in select cases depending on autoimmune or alloimmune dysfunction.
The Use of IVF in the Treatment of RPL
In the following circumstances, IVF is the preferred option:
1.When in addition to a history of RPL, another standard indication for IVF (e.g., tubal factor, endometriosis, and male factor infertility) is superimposed.
2.In cases where selective immunotherapy is needed to treat an immunologic implantation dysfunction.
The reason for IVF being a preferred approach in such cases is that in order to be effective, the immunotherapy needs to be initiated well before spontaneous or induced ovulation. Given the fact that the anticipated birthrate per cycle of COS with or without IUI is at best about 15%, it follows that short of IVF, to have even a reasonable chance of a live birth, most women with immunologic causes of RPL would need to undergo immunotherapy repeatedly, over consecutive cycles. Conversely, with IVF, the chance of a successful outcome in a single cycle of treatment is several times greater and, because of the attenuated and concentrated time period required for treatment, IVF is far safer and thus represents a more practicable alternative
Since embryo aneuploidy is a common cause of miscarriage, the use of preimplantation genetic diagnosis (PGD), with tests such as CGH, can provide a valuable diagnostic and therapeutic advantage in cases of RPL. PGD requires IVF to provide access to embryos for testing.
There are a few cases of intractable alloimmune dysfunction due to absolute DQ alpha matching where Gestational Surrogacy or use of donor sperm could represent the only viable recourse, other than abandoning treatment altogether and/or resorting to adoption. Other non-immunologic factors such as an intractably thin uterine lining or severe uterine pathology might also warrant that last resort consideration be given to gestational surrogacy.
The good news is that if a couple with RPL is open to all of the diagnostic and treatment options referred to above, a live birthrate of 70%–80% is ultimately achievable.

I had a quick question on ICSI vs Petri dish or natural method of fertilization. My Nurse was asking me to choose the number of eggs I would like to fertilize using ICSI and number of eggs with normal method(petri dish). I am not sure on what basis do I choose the number of eggs for these 2 methods. I would like your inputs or suggestions, please. Also, does implantation of these 2 methods impact in any way? does embryo quality decrease in either of the method? I am planning to do the PGD PGS testing of the embryos too.
Appreciate your response. Thank you!
This is a controversial issue. However, I personally recommend universal ICSI for my patients (all eggs).

Hello Dr Sher,
A quick history before I ask my question.
My partner and I have the sickle cell trait, we were lucky enough to get pregnant within the first month of trying on both occasions Jan & Dec 2011 when we started TTC but as luck would have it both were homozygous for SCD so I had a D&C. After the 2nd D&C we started experincing secondary infertility and tried on and off for some years until we decided to start fertility treatment with PGS/PGD embryos. That’s when I discovered that I have scarring and a stubborn thin endo-lining issue mostlikely due to the D&Cs.. My previous clinic had tried Gonal F injections to boost my lining but it never got up to 7mm, i asked my RE about Sildenafil but he wasnt open to it – my transfers were not succesful there.. I swicthed clinics and my new RE was very open minded. We tried a viagra and oral estrace protocol and my lining got to over 8mm, there was fluid found mid-way but my Dr gave me confidence that he wasnt worried about it and he was sure it would dry up and it did while i was on PIO. I had a final U/S check a day before transfer just to make sure.. I tranfered 1 embyo in July 2019 and it worked.. unfortunately I lost the baby due to anencephaly but she was genetically normal. In between that time and being prepared to try again my RE had left my fertility clinic. My new RE canceled my FET in July and August due to the fluid issue.. I was already over 7mm when she cancelled in July and said we should try Gonal because estrace can cause fluid side effects.. She put me on provera for 10 days and I had a sono and she said all looked fine. We tried gonal F along with viagra suppositories in August. The fluid still appeared plus my linning didnt even get up to 6mm. So it didnt work as i had suspected.
Now my confidence is really down and I am frustrated with this decade long journey. I have sent an email to my RE requesting that we use the protocol that has proven to work for me. Viagra + Oral Estrace.
What protocol would you recommend for a case like mine?
Looking forward to your feedback.

It was as far back as 1989, when I first published a study that examined the correlation between the thickness of a woman’s uterine lining (the endometrium), and the subsequent successful implantation of embryos in IVF patients. This study revealed that when the uterine lining measured <8mm in thickness by the day of the “hCG trigger” (in fresh IVF cycles), or at the time of initiating progesterone therapy (in embryo recipient cycles, e.g. frozen embryo transfers-FET, egg donation-IVF etc.) , pregnancy and birth rates were substantially improved. Currently, it is my opinion, that an ideal estrogen-promoted endometrial lining should ideally measure at least 9mm in thickness and that an endometrial lining measuring 8-9mm is “intermediate”. An estrogenic lining of <8mm is in most cases unlikely to yield a viable pregnancy.
A “poor” uterine lining is usually the result of the innermost layer of endometrium (the basal or germinal endometrium from which endometrium grows) ) not being able to respond to estrogen by propagating an outer, “functional” layer thick enough to support optimal embryo implantation and development of a healthy placenta (placentation). The “functional” layer ultimately comprises 2/3 of the full endometrial thickness and is the layer that sheds with menstruation in the event that no pregnancy occurs.
The main causes of a “poor” uterine lining are:
1.Damage to the basal endometrium as a result of:
a.Inflammation of the endometrium (endometritis) most commonly resulting from infected products left over following abortion, miscarriage or birth
b.Surgical trauma due to traumatic uterine scraping, (i.e. due to an over-aggressive D & C)
2.Insensitivity of the basal endometrium to estrogen due to:
a.Prolonged , over-use/misuse of clomiphene citrate
b.Prenatal exposure to diethylstilbestrol (DES). This is a drug that was given to pregnant women in the 1960’s to help prevent miscarriage
3.Over-exposure of the uterine lining to ovarian male hormones (mainly testosterone): Older women, women with diminished ovarian reserve (poor responders) and women with polycystic ovarian syndrome -PCOS tend to have raised LH biological activity.. This causes the connective tissue in the ovary (stroma/theca) to overproduce testosterone. The effect can be further exaggerated when certain methods for ovarian stimulation such as agonist (Lupron/Buserelin) “flare” protocols and high dosages of menotropins such as Menopur are used in such cases.
4.Reduced blood flow to the basal endometrium:
Examples include;
a.Multiple uterine fibroids - especially when these are present under the endometrium (submucosal)
b.Uterine adenomyosis (excessive, abnormal invasion of the uterine muscle by endometrial glands).
“The Viagra Connection”
Eighteen years ago years ago, after reporting on the benefit of vaginal Sildenafil (Viagra) for to women who had implantation dysfunction due to thin endometrial linings I was proud to announce the birth of the world’s first “Viagra baby.” Since the introduction of this form of treatment, thousands of women with thin uterine linings have been reported treated and many have gone on to have babies after repeated prior IVF failure.
For those of you who aren’t familiar with the use of Viagra in IVF, allow me to provide some context. It was in the 90’s that Sildenafil (brand named Viagra) started gaining popularity as a treatment for erectile dysfunction. The mechanism by which it acted was through increasing penile blood flow through increasing nitric oxide activity. This prompted me to investigate whether Viagra administered vaginally, might similarly improve uterine blood flow and in the process cause more estrogen to be delivered to the basal endometrium and thereby increase endometrial thickening. We found that when Viagra was administered vaginally it did just that! However oral administration was without any significant benefit in this regard. We enlisted the services of a compound pharmacy to produce vaginal Viagra suppositories. Initially, four (4) women with chronic histories of poor endometrial development and failure to conceive following several advanced fertility treatments were evaluated for a period of 4-6 weeks and then underwent IVF with concomitant Viagra therapy. Viagra suppositories were administered four times daily for 8-11 days and were discontinued 5-7 days prior to embryo transfer in all cases.
Our findings clearly demonstrated that vaginal Viagra produced a rapid and profound improvement in uterine blood flow and that was followed by enhanced endometrial development in all four cases. Three (3) of the four women subsequently conceived. I expanded the trial in 2002 and became the first to report on the administration of vaginal Viagra to 105 women with repeated IVF failure due to persistently thin endometrial linings. All of the women had experienced at least two (2) prior IVF failures attributed to intractably thin uterine linings. About 70% of these women responded to treatment with Viagra suppositories with a marked improvement in endometrial thickness. Forty five percent (45%) achieved live births following a single cycle of IVF treatment with Viagra The miscarriage rate was 9%. None of the women who had failed to show an improvement in endometrial thickness following Viagra treatment achieved viable pregnancies.
Following vaginal administration, Viagra is rapidly absorbed and quickly reaches the uterine blood system in high concentrations. Thereupon it dilutes out as it is absorbed into the systemic circulation. This probably explains why treatment is virtually devoid of systemic side effects
It is important to recognize that Viagra will NOT be effective in improving endometrial thickness in all cases. In fact, about 30%-40% of women treated fail to show any improvement. This is because in certain cases of thin uterine linings, the basal endometrium will have been permanently damaged and left unresponsive to estrogen. This happens in cases of severe endometrial damage due mainly to post-pregnancy endometritis (inflammation), chronic granulomatous inflammation due to uterine tuberculosis (hardly ever seen in the United States) and following extensive surgical injury to the basal endometrium (as sometimes occurs following over-zealous D&C’s).
Combining vaginal Viagra Therapy with oral Terbutaline;
In my practice I sometimes recommend combining Viagra administration with 5mg of oral terbutaline. The Viagra relaxes the muscle walls of uterine spiral arteries that feed the basal (germinal) layer of the endometrium while Terbutaline, relaxes the uterine muscle through which these spiral arteries pass. The combination of these two medications interacts synergistically to maximally enhance blood flow through the uterus, thereby improving estrogen delivery to the endometrial lining. The only drawback in using Terbutaline is that some women experience agitation, tremors and palpitations. In such cases the terbutaline should be discontinued. Terbutaline should also not be used women who have cardiac disease or in those who have an irregular heartbeat.
About 75% of women with thin uterine linings see a positive response to treatment within 2-3 days. The ones that do not respond well to this treatment are those who have severely damaged inner (basal/germinal) endometrial linings, such that no improvement in uterine blood flow can coax an improved response. Such cases are most commonly the result of prior pregnancy-related endometrial inflammation (endometritis) that sometimes occurs post abortally or following infected vaginal and/or cesarean delivery.
Viagra therapy has proven to be a god send to thousands of woman who because of a thin uterine lining would otherwise never have been able to successfully complete the journey “from infertility to family”.

Addendum:
I recommend that you discuss the protocol FET as below , with your RE. I personally do not agree with the use of oral estrogen for FET.
Until less than a decade ago, most women undergoing IVF would have embryos transferred to the uterus in the same cycle that the egg retrieval was performed (“Fresh” Embryo Transfer). This was because embryo cryopreservation (freezing) was a hazardous undertaking. In fact, it resulted in about 30% not surviving the freezing process and those that did, having about one half the potential of “fresh embryos to implant and propagate a viable pregnancy. The main reason for the high attrition rate associated with embryo cryopreservation is that the “conventional” freezing” process that was done slowly and this resulted in ice forming within the embryo’s cells, damaging or destroying them. The introduction of an ultra-rapid cryopreservation process (vitrification) freezes the embryos so rapidly as to avoid ice crystals from developing. As a result, >90% survive the freeze/thaw process in as good a condition as they were prior to being frozen and thus without being compromised in their ability to propagate a viable pregnancy.
Recently, there have been several articles that have appeared in the literature suggest that an altered hormonal environment may be the reason for this effect. There have also been reports showing that when singletons (pregnancy with one baby) conceived naturally are compared to singletons conceived through a “fresh” embryo transfers they tend to have a greater chance of low birth weight/prematurity. This difference was not observed in babies born following FET. Hence, there is a suspicion that the altered hormonal environment during the fresh cycle may be the causative factor.
Available evidence suggests that FET (of pre-vitrified blastocysts) is at least as successful as is the transfer of “fresh” embryos and might even have the edge. The reason for this is certainly unlikely to have anything to do with the freezing process itself. It more than likely has to do with two factors:
a)An ever increasing percentage of FET’s involve the transfer of PGS-tested, fully karyotyped, euploid blastocysts that have a greater potential to propagate viable pregnancies, than is the case with “fresh” ET’s where the embryos have rarely undergone prior PGS selection for “competency”…and,
b) With targeted hormone replacement therapy for FET, one is far better able to better to optimally prepare the endometrium for healthy implantation than is the case where embryos are transferre3d following ovarian stimulation with fertility drugs.
There are additional factors other than method used for embryo cryopreservation that influence outcome following FET. These include
•An emerging trend towards selective transferring only advanced (day 5-6) embryos (blastocysts).
• (PGS) to allow for the selective transfer of genetic competent (euploid) embryos
•Addressing underlying causes of implantation dysfunction (anatomical and immunologic uterine factors) and
• Exclusive use of ultrasound guidance for delivery of embryos transferred to the uterus.
Against this background, the use of FET has several decided advantages:
•The ability to cryostore surplus embryos left over after fresh embryo transfer
•The ability to safely hold embryos over for subsequent transfer in a later frozen embryo transfer (FET) cycle (i.e. Staggered IVF) in cases where:
1.Additional time is needed to perform preimplantation Genetic testing for embryo competency.
2.In cases where ovarian hyperstimulation increases the risk of life-endangering complications associated with critically severe ovarian hyperstimulation syndrome (OHSS).
3.To bank (stockpile) embryos for selective transfer of karyotypically normal embryos in older women or those who are diminished ovarian reserve
4.The ability to store embryos in cases of IVF with third party parenting (Egg Donation; Gestational Surrogacy and Embryo donation) and so improve convenience for those couples seeking such services.
Preimplantation Genetic Sampling with FET:
The introduction of preimplantation genetic sampling (PGS) to karyotyping of embryos for selective transfer of the most “competent” embryos, requires in most cases that the tested blastocysts be vitribanked while awaiting test results and then transferred to the uterus at a later date. Many IVF programs have advocated the routine use of PGS in IVF purported to improve IVF outcome. But PGS should in my opinion should only be used selectively. I do not believe that it is needed for all women undergoing IVF. First there is the significant additional cost involved and second it will not benefit everyone undergoing IVF, in my opinion.
While PGS is a good approach for older women and those with diminished ovarian reserve (DOR) and also for woman who experience recurrent pregnancy loss (RPL) or “unexplained” recurrent IVF failure recent data suggests that it will not improve IVF success rates in women under 36Y who have normal ovarian reserve, who represent the majority of women seeking IVF treatment. Nor is it needed in women (regardless of their age) undergoing IVF with eggs donated by a younger donor. This is because in such women about 1:2/3 of their eggs/embryos are usually chromosomally normal, and in most cases will upon fertilization produce multiple blastocysts per IVF attempt, anyway. Thus in such cases the transfer of 2 blastocysts will likely yield the same outcome regardless of whether the embryos had been subjected to PGS or not. The routine use of
It is another matter when it comes to women who have diminished ovarian reserve and/or DOR contemplating embryo banking and for women with unexplained recurrent IVF failure, recurrent pregnancy loss and women with alloimmune implantation dysfunction who regardless of their age or ovarian reserve require PGS for diagnostic reasons.
Embryo Banking: Some IVF centers are doing embryo banking cycles with Preimplantation Genetic Screening (PGS). With Embryo Banking” several IVF cycles are performed sequentially (usually about 2 months apart), up to the egg retrieval stage. The eggs are fertilized and the resulting advanced embryos are biopsied. The biopsy specimens are held over until enough 4-8 blastocysts have been vitribanked, thus providing a reasonable likelihood that one or more will turn out to be PGS-normal. At this point the biopsy specimens (derived all banking cycles) are sent for PGS testing at one time (a significant cost-saver), the chromosomally normal blastocysts are identified and the women are scheduled for timed FET procedures….. with a good prospect of a markedly improved chance of success as well as a reduced risk of miscarriage.
Standard (proposed) Regimen for preparing the uterus for frozen embryo transfer FET) is as follows:
The recipient’s cycle is initiated with an oral contraceptive-OC (e.g. Marvelon/Lo-Estrin; Lo-Ovral etc) for at least 10 days. This is later overlapped with 0.5 mg. (10 units) Lupron/Lucrin (or Superfact/Buserelin) daily for 3 days. Thereupon the OC is withdrawn and daily 0.25 mg (5 units) of Lupron/Lucrin/Superfact injections are continued. Menstruation will usually ensue within 1 week. At this point, an ultrasound examination is performed to exclude ovarian cyst(s) and a blood estradiol measurement is taken (it needs to be <70pg/ml) until daily progesterone administration is initiated some time later. The daily Lupron/Lucrin/Superfact is continued until the initiation of progesterone therapy (see below).
Four milligram (4mg) Estradiol valerate (Delestrogen) IM is injected SC, twice weekly (on Tuesday and Friday), commencing within a few days of Lupron/Lucrin/Superfact-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 3rd dosage of Delestrogen.. The twice weekly, final (adjusted) dosage of E2V is continued until pregnancy is discounted by blood testing or an ultrasound examination. Dexamethasone 0.75 mg is taken orally, daily with the start of the Lupron/Lucrin/Superfact. Oral folic acid (1 mg) is taken daily commencing with the first E2V injection and is continued throughout gestation. Patients also receive Ciprofloxin 500mg BID orally starting with the initiation of Progesterone therapy and continuing for 10 days.
Luteal support commences 6 days prior to the ET, with intramuscular progesterone in oil (PIO) at an initial dose of 50 mg (P4-Day 1). Starting on progesterone administration-Day 2, PIO is increased to 100 mg daily continuing until the 10th week of pregnancy, or until a blood pregnancy test/negative ultrasound (after the 6-7th gestational week), discounts a viable pregnancy.
Also, commencing on the day following the ET, 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 10th week of pregnancy or until pregnancy is discounted by blood testing or by an ultrasound examination after the 6-7th gestational week. Dexamethasone o.75mg is continued to the 10th week of pregnancy (tailed off from the 8th to 10th week) or as soon as pregnancy is ruled out. With the obvious exception of the fact that embryo recipients do not receive an hCG injections, luteal phase and early pregnancy hormonal support and immuno-suppression is otherwise the same as for conventional IVF patients. Blood pregnancy tests are performed 13 days and 15 days after the first P4 injection was given.
Note: One (1) vaginal application of Crinone 8% is administered on the 1st day (referred to as luteal phase day 0 – LPO). On LP Day 1, they will commence the administration of Crinone 8% twice daily (AM and PM) until the day of embryo transfer. Withhold Crinone on the morning of the embryo transfer and resume Crinone administration in the PM. Crinone twice daily is resumed from the day after embryo transfer. Contingent upon positive blood pregnancy tests, and subsequently upon the ultrasound confirmation of a viable pregnancy, administration of Crinone twice daily are continued until the 10th week of pregnancy.

Hello dear Dr.
Is a grade 5AA embryo a good normal embryo?
Thanks.
Jess
Yes it likely is!
