Dear Dr Asher,
I have one boy via donor egg. From a second cycle with a proven donor, I have 5 frozen blastocysts. Two are graded as 4ab. The remaining 3 are early blasts.
How many should I transfer during my FET cycle?
Many Thanks
Ashley
Apologies Dr Sher (iPhone changed your name to Asher)
One or two. But that decision is up to you whether you are willing to countenance having twins . The risk if that having is probably around 1:4.
Good luck!

I transferred 2 5 day blasts FET. I found out I was pregnant 10 days post FET with a BETA HCG level of 206 Progesterone 109. Day 15 I repeated bloodwork and my HCG had jumped appropriately to 1537 but progesterone has fallen to 29.75. Doc assuremed me not to worry as this was still in an ok range. That same night I started bleeding. I bled for about 3 hours lightly and passed a blood clot and white tissue like substance. I went for bloodwork the next morning and found my HCG had dropped but only to 1153 and my progesterone had jumped to 75.90. Very conflicting blood results. I have been instructed to be on bedrest and come back in 3 days (after the weekend) and check levels again. Bleeding stopped totally after I passed the clot. This is my second FET the first resulted in miscarriage at 6 weeks. Am I having a miscarriage again? Doctor said I could have lost 1 embryo but not the other? Any answers you can give would be great! Thanks
I would do a repeat hCG test on Monday + an ultrasound examination to see what is going on.It could be that you started with a twin pregnancy and have just lost one.
Good luck!

Hi Dr. Sher,
We just completed our second unsuccessful IVF cycle. From the two cycles, a total of 7 embryos were frozen and PGS tested – they all tested abnormal. I just turned 39, have severe endometriosis and had my right ovary and tube removed due to endo last year during laparoscopic surgery. Despite these negatives, my AMH is still decent, antral follicle count high, and I was a high responder in both cycles, leaving my doctor pleasantly surprised. During the first cycle my E2 got dangerously high (11,000) and my doctor thought that his too-aggressive stimulation approach may have compromised egg quality. So on the second cycle, we began with 150 IU Follistim and tapered off from there (first round had started with 300 IU). Even at 150, my E2 quickly got high immediately, so he backed off more and added in Menopur for what I understood to be continued but gentle stimulation. (Both cycles brought in Menopur and Ganirelix.) Still, our 3 embryos that “looked” good at day 5 still came back abnormal.
My question – if we can afford another IVF cycle, besides lowering the stimulation further, is there anything else you suggest we investigate?
Endometriosis is a condition that occurs when the uterine lining (endometrium) grows not only in the interior of the uterus but in other areas, such as the fallopian tubes, ovaries and the bowel. Endometriosis is a complex condition where, the lack or relative absence of an overt anatomical barrier to fertility often belies the true extent of reproductive problem(s).
All too often the view is expounded that the severity of endometriosis-related infertility is inevitably directly proportionate to the anatomical severity of the disease itself, thereby implying that endometriosis causes infertility primarily by virtue of creating anatomical barriers to fertilization. This over-simplistic and erroneous view is often used to support the performance of many unnecessary surgeries for the removal of small innocuous endometriotic lesions, on the basis of such “treatment” evoking an improvement in subsequent fertility.
It is indisputable that even the mildest form of endometriosis can compromise fertility. It is equally true that, mild to moderate endometriosis is by no means a cause of absolute “sterility”.
Rather, when compared with normally ovulating women of a similar age who do not have endometriosis, women with mild to moderate endometriosis are about four to six times less likely to have a successful pregnancy.
Endometriosis often goes unnoticed for many years. Such patients are frequently, erroneously labeled as having “unexplained infertility”, until the diagnosis is finally clinched through direct visualization of the lesions at the time of laparoscopy or laparoscopy. Not surprisingly, many patients with so called “unexplained” infertility, if followed for a number of years, will ultimately reveal endometriosis.
Women who have endometriosis are much more likely to be infertile. There are several reasons for this:
•First-Ovulation Dysfunction: In about 25 – 30% of cases, endometriosis is associated with ovulation dysfunction. Treatment requires controlled ovarian stimulation (COS). The problem is that the toxic pelvic environment markedly reduces the likelihood that anything other than IVF will enhance pregnancy potential.
•Second- Toxic Pelvic environment that compromises Fertilization Endometriosis is associated with the presence of toxins in peritoneal secretions while it is tempting to assert that normally ovulating women with mild to moderate endometriosis would have no difficulty in conceiving if their anatomical disease is addressed surgically or that endometriosis-related infertility is confined to cases with more severe anatomical disease…nothing could be further from the truth. The natural conception rate for healthy ovulating women in their early 30’s (who are free of endometriosis) is about 15% per month of trying and 70% per year of actively attempting to conceive. Conversely, the conception rate for women of a comparable age who have mild or moderate pelvic endometriosis (absent or limited anatomical disease) is about 5-6% per month and 40% after 3 years of trying. As sperm and egg(s) travel towards the fallopian tubes they are exposed to these toxins which compromise the fertilization process. In fact it has been estimated that there is a 5-6 fold reduction in fertilization potential because of these toxins which cannot be eradicated. Frankly, it really does not matter whether an attempt is made to remove endometriosis deposits surgically as this will not improve pregnancy potential. The reason is that for every deposit observed, there are numerous others that are in the process of developing and are not visible to the naked eye and whether visible or not, such translucent deposits still produce toxins. This also explains why surgery to remove visible endometriosis deposits, controlled ovarian stimulation with or without intrauterine insemination will usually not improve pregnancy potential. Only IVF, through removing eggs before they are exposed to the toxic pelvic environment, fertilizing them in-vitro and then transferring the embryos to the uterus represents the only way to enhance pregnancy potential.
•Third-Pelvic adhesions and Scarring: In its most severe form, endometriosis is associated with scarring and adhesions in the pelvis, resulting in damage to, obstruction or fixation of the fallopian tubes to surrounding structures, thereby preventing the union of sperm and eggs.
•Fourth-Ovarian Endometriomas, Advanced endometriosis is often associated with ovarian cysts (endometriomas/chocolate cysts) that are filled with altered blood and can be large and multiple. When these are sizable (>1cm) they can activate surrounding ovarian connective tissue causing production of excessive male hormones (androgens) such as testosterone and androstenedione. Excessive ovarian androgens can compromise egg development in the affected ovary (ies) resulting in an increased likelihood of numerical chromosomal abnormalities (aneuploidy) and reduced egg/embryo competency”. In my opinion large ovarian endometriomas need to be removed surgically or rough sclerotherapy before embarking on IVF.
•Fifth- Immunologic Implantation Dysfunction (IID). Endometriosis, regardless of its severity is associated with immunologic implantation dysfunction linked to activation of uterine natural killer cells (NKa) and cytotoxic uterine lymphocytes (CTL) in about 30 of cases. This is diagnosed by testing the woman’s blood for NKa using the K-562 target cell test or by endometrial biopsy for cytokine analysis, and, for CTL by doing a blood immunophenotype. These NKa attack the invading trophoblast cells (developing “root system” of the embryo/early conceptus) as soon as it tries to gain attachment to the uterine wall. In most cases, this results in death of the embryo even before the pregnancy is diagnosed and sometimes, in a chemical pregnancy or even an early miscarriage. . As such, many women with endometriosis, rather than being infertile, in the strict sense of the word, often actually experience repeated undetected “mini-miscarriages”.
Advanced Endometriosis: In its most advanced stage, anatomical disfiguration is causally linked to the infertility. In such cases, inspection at laparoscopy or laparoscopy will usually reveal severe pelvic adhesions, scarring and “chocolate cysts”. However, the quality of life of patients with advanced endometriosis is usually so severely compromised by pain and discomfort, that having a baby is often low on the priority list. Accordingly, such patients are usually often more interested in relatively radical medical and surgical treatment options (might preclude a subsequent pregnancy), such as removal of ovaries, fallopian pubis and even the uterus, as a means of alleviating suffering.
Moderately Severe Endometriosis. These patients have a modest amount of scarring/ adhesions and endometriotic deposits which are usually detected on the ovaries, fallopian tubes, bladder surface and low in the pelvis, behind the uterus. In such cases, the fallopian tubes are usually opened and functional.
Mild Endometriosis: These patients who at laparoscopy or laparotomy are found to have no significant distortion of pelvic anatomy are often erroneously labeled as having “unexplained” infertility. To hold that the there can only infertility can only be attributed to endometriosis if significant anatomical disease can be identified, is to ignore the fact that, biochemical, hormonal and immunological factors profoundly impact fertility. Failure to recognize this salient fact continues to play havoc with the hopes and dreams of many infertile endometriosis patients.
TREATMENT:
The following basic concepts apply to management of endometriosis-related infertility:
1.Controlled Ovulation stimulation (COS) with/without intrauterine insemination (IUI): Toxins in the peritoneal secretions of women with endometriosis exert a negative effect on fertilization potential regardless of how sperm reaches the fallopian tubes. This helps explain why COS with or without IUI will usually not improve the chances of pregnancy (over no treatment at all) in women with endometriosis. IVF is the only way by which to bypass this problem.
2.Laparoscopy or Laparotomy Surgery aimed at restoring the anatomical integrity of the fallopian tubes does not counter the negative influence of toxic peritoneal factors that inherently reduce the chances of conception in women with endometriosis four to six fold. Nor does it address the immunologic implantation dysfunction (IID) commonly associated with this condition. Pelvic surgery is relatively contraindicated for the treatment of infertility associated with endometriosis, when the woman is more than 35 years of age. With the pre-menopause approaching, such women do not have the time to waste on such less efficacious alternatives. In contrast, younger women who have time on their side might consider surgery as a viable option. Approximately 30 -40 percent of women under 35 years of age with endometriosis will conceive with in two to three years following corrective pelvic surgery.
3.Sclerotherapy for ovarian endometriomas (“chocolate” cysts). About 15 years ago I introduced “sclerotherapy”, a relatively non-invasive, safe and effective outpatient method to permanently eliminate endometriomas without surgery being required. Sclerotherapy for ovarian endometriomas involves needle aspiration of the liquid content of the endometriotic cyst, followed by the injection of 5% tetracycline into the cyst cavity. Treatment results in disappearance of the lesion within 6-8 weeks, in more than 75% of cases so treated. Ovarian sclerotherapy can be performed under local anesthesia or under general anesthesia. It has the advantage of being an ambulatory office- based procedure, at low cost, with a low incidence of significant post-procedural pain or complications and the avoidance of the need for laparoscopy or laparotomy
4.The role of selective immunotherapy More than half of women who have endometriosis harbor antiphospholipid antibodies (APA) that can compromise development of the embryo’s root system (trophoblast). In addition and far more serious, is the fact that in about one third of cases endometriosis, regardless of its severity is associated with NKa and cytotoxic uterine lymphocytes (CTL) which can seriously jeopardize implantation. This immunologic implantation dysfunction (IID) is diagnosed by testing the woman’s blood for APA, for NKa (using the K-562 target cell test or by endometrial biopsy for cytokine activity) and, for CTL (by a blood immunophenotype). Activated NK cells attack the invading trophoblast cells (developing “root system” of the embryo/early conceptus) as soon as it tries to gain attachment to the uterine wall. In most cases, this results in rejection of the embryo even before the pregnancy is diagnosed and sometimes, in a chemical pregnancy or an early miscarriage. . As such, many women with endometriosis, rather than being infertile, in the strict sense of the word, often actually experience repeated undetected “mini-miscarriages”.
Women who harbor APA’s often experience improved IVF birth rates when heparinoids (Clexane/Lovenox) are administered from the onset of ovarian stimulation with gonadotropins until the 10th week of pregnancy. NKa is treated with a combination of Intralipid (IL) and steroid therapy: Intralipid (IL) is a solution of small lipid droplets suspended in water. When administered intravenously, IL provides essential fatty acids, linoleic acid (LA), an omega-6 fatty acid, alpha-linolenic acid (ALA), an omega-3 fatty acid.IL is made up of 20% soybean oil/fatty acids (comprising linoleic acid, oleic acid, palmitic acid, linolenic acid and stearic acid) , 1.2% egg yolk phospholipids (1.2%), glycerin (2.25%) and water (76.5%).IL exerts a modulating effect on certain immune cellular mechanisms largely by down-regulating NKa.
The therapeutic effect of IL/steroid therapy is likely due to an ability to suppress pro-inflammatory cellular (Type-1) cytokines such as interferon gamma and TNF-alpha. IL/steroids down-regulates NKa within 2-3 weeks of treatment the vast majority of women experiencing immunologic implantation dysfunction. In this regard IL is just as effective as Intravenous Gamma globulin (IVIg) but at a fraction of the cost and with a far lower incidence of side-effects. Its effect lasts for 4-9 weeks when administered in early pregnancy.
5.The role of IVF: The toxic pelvic environment caused by endometriosis, profoundly reduces natural fertilization potential. As a result normally ovulating infertile women with endometriosis and patent Fallopian tubes are much less likely to conceive naturally, or by using fertility agents alone (with or without intrauterine (IUI) insemination. The only effective way to bypass this adverse pelvic environment is through IVF. I am not suggesting here that all women who have endometriosis require IVF! Rather, I am saying that in cases where the condition is further compromised by an IID associated with NKa and/or for older women(over 35y) who have diminished ovarian reserve (DOR) where time is of the essence, it is my opinion that IVF is the treatment of choice.

My fet is due on 21st October. My e2 level has come back today and it is 500pmol and that’s on Day 2 of my period. I have had a scan and I don’t have any cysts and my lining is 1mm. My period is very light and I have just come off the bcp. Can I still start my cycle for FET in your opinion? Can you suggest any reasons why it would be high on day 2 of my period? Thank you for your help
In my opinion, provided this is an FET and you are not undergoing ovarian stimulation, you could start.
Geoff Sher
Do you believe that having one loss with a genetically normal embryo is indicative of having another? I’m trying to think that this was just our first transfer, and science isn’t perfect, and sometimes it’s just bad luck, so we still have the same shot at getting it right next time. But is there anything indicated for next time that it could be the same outcome?
Thank you so much.
Embryo competency as assessed by PGS is NOT the only issue when it comes to IVF outcome.
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 a decade 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).
3.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.
4.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:
a.A“ thin uterine lining”
b.A uterus with surface lesions in the cavity (polyps, fibroids, scar tissue)
c.Immunologic implantation dysfunction (IID)
d.Endocrine/molecular endometrial receptivity issues
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).
