Hi Dr. Sher,
I am 29 years old and have been diagnosed with PCOS and endometriosis. I have had two laparoscopies one of which I had a large cyst removed from my ovary and lost a significant portion of that ovary. I have a low AMH and after 3 years of trying to conceive naturally, and using clomid, my Dr. Suggested ivf. We had our first cycle in April. I was put on menopur and gonal and we got 4 eggs. Of the 4, all fertilized and 2 made it to blastocyst. We transferred one, it failed. We then did a FET, it failed.
We decided to try again and this time they added lupron, and human growth hormone to try to improve our embryos. We got 6 eggs, 5 were mature, 4 fertilized, 3 made it to blastocyst. We transferred two embryos, and the cycle failed. My doctor said the embryo’s are a good quality and did a hysteroscopy and saw no issues in my uterus. Also before our last cycle we did an endometrial scratching to improve chance of implantation. I feel so defeated and devastated. We have invested nearly 50k and still no baby. We have one frozen embryo left, I’m curious if you think it’s even worth trying again or if it’s time to give up. Also, if you do think it’s worth trying again, my doctor said she suggests a blood thinner and a medication to lower my estrogen levels to improve chances of implantation since she feels this is the main problem.
I welcome any and all feedback and advice and I so appreciate it!

This sounds like an implantation dysfunction to me…possibly immunologic, in view of the endometriosis. This needs to be assessed carefully. Also, b=ear in mind that women with DOR require a very individualized approach to ovarian stimulation…see below:
1. Endometriosis and immunologic implantation dysfunction:
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.
2. Why did IVF fail?
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).
Women who (regardless of age) have DOR have a reduced potential for IVF success. Much of this is due to the fact that such women tend to have increased production of LH biological activity which can result in excessive LH-induced ovarian male hormone (predominantly testosterone) production which in turn can have a deleterious effect on egg/embryo “competency”.
While it is presently not possible by any means, to reverse DOR, certain stimulation regimes, by promoting excessive LH production (e.g. short agonist/Lupron- “flare” protocols, clomiphene and Letrozole), can make matters worse. Similarly, the amount/dosage of certain fertility drugs that contain LH/hCG (e.g. Menopur) can have a negative effect on the development of the eggs of older women who have DOR and should be limited.
I try to avoid using such protocols/regimes (especially) in women with DOR, favoring instead the use of the agonist/antagonist conversion protocol (A/ACP), a modified, long pituitary down-regulation regime, augmented by adding supplementary human growth hormone (HGH). I further recommend that such women be offered access to embryo banking of PGS (next generation gene sequencing/NGS)-selected normal blastocysts, the subsequent selective transfer of which by allowing them to capitalize on whatever residual ovarian reserve and egg quality might still exist and thereby “make hay while the sun still shines” could significantly enhance the opportunity to achieve a viable pregnancy

Dr. Sher,
I am just curious on your opinion regarding weight and fertility. I am 5’2″ and 105lbs. I have completed one IVF cycle, where I got one embryo. I had a positive pregnancy test and lost it approx 1 week later. Our specialist believes we have an egg quality issue.
My doctor has stated that he would like me to gain weight for our next IVF cycle. He basically stated he wanted me to ‘pig out’. I am curious what role weight has in egg quality and fertility? Do you believe that ‘pigging out’ to gain weight is a good idea? Does it matter what types of foods I use to increase my weight, as our doctor suggested that the fattier the better. He has joked with us that he wants a ‘banana-split diet’. I am traditionally a very healthy eater. I have had my blood tested, and the only deficiency I show is B12 (which I have been on shots on for years). Thanks in advance.
Hi Katie,
If you do not have an eating disorder or a medical condition causing you to lose weight, I do not believe that this should be an issue that would directly impact egg/embryo “competency”. You need to look for other factors that could be causing IVF failure.

Hello Dr. Sher,
I am currently going through my 4th and final attempt for my IVF cycle. It seems to get worse and worse every attempt. Currently I am on a microdose lupron protocol. I was on estrace for a about a week before I started my lupron and taking 20 units twice a day. I am also taking Gonal-F 300 units, menopur and omnitrope every other day. After 7 days of stim, nothing! My follicles are not responding. Currently I have 7 follicles at around 7mm. Anyways, I am concern this estrace priming and microdose lupron has over suppressed my ovaries, but my doctor doesn’t think so. I have been on a similiar protocol before, with the exception of adding omnitrope this time, and a similiar outcome like this happened. Any advice?
It sounds as if you have diminished ovarian reserve (DOR). Women who (regardless of age) have DOR have a reduced potential for IVF success. Much of this is due to the fact that such women tend to have increased production of LH biological activity which can result in excessive LH-induced ovarian male hormone (predominantly testosterone) production which in turn can have a deleterious effect on egg/embryo “competency”.

Hello, I am new to this site and to this journey. My story is a little bit different. I’m 38 and have never tried to conceive naturally because the timing wasn’t right. My SO and I have been together a little over a year and made the decision to PGS and freeze embryos to use in a year or 2 when we were ready. I had 15 eggs retrieved, 10 were mature and another matured in vitro. 11 fertilized through ICSI and all made it to day 3. Only a few made it to blastocyst and they were all considered very poor quality. There were none to biopsy or freeze. We are devastated. My RE says he can’t rule out a sperm factor but thinks most likely my eggs are just too old (more like a 42-43 year-old). He recommended not trying again (I have to pay all out of pocket).
Is it completely hopeless? Should we try naturally or try a second round ASAP (can’t afford more than one more at this time)? Any recommendation for supplements? Thank you!
I absolutely do not believe that this is likely to be an egg issue at 38y. It is in my opinion, more likely to be a stimulation protocol issue.
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.
I hope this helps!

Help! Ok, I’m 36Y female who just started the IVF process in hopes to hire a surrogate because I have Ulcerative Colitis and Medically Induced Lupus due to a biological immunosuppressant medicine I was on.
Long story short, we started the IVF officially last week. All I have started doing was on day two of my period (last Tuesday) I began taking testosterone gel. I will take this for one month and then proceed with the actual IVF injections and egg retrieval. I, however am terrified I screwed things up by taking a medicine I probably should not have while being on the testosterone. Due to my illness, and probably stress of starting all of this I started flaring pretty bad last week. I decided to do what I always do and begin a round of my prednisone. (I usually always have some extra around and when I flare I mostly go to the docs but to save time and money I know what they will say/do so I sometimes just play doctor and treat myself – bad, I know! I can take a few pills of my prednisone for a few days and the flares subside. – I know…this is not great practice but I’m still waiting on the new biological Med I’m trying to start working.) Anyways, AFTER I took my usual pills of prednisone, (only took x2 10mg in 2 days) THEN my dumb butt looked up what pred does with testosterone/fertility and I saw it’s one of the drugs that is a “No-No!” when trying to get pregnant, because it can prevent your pituitary gland from releasing enough follicle-stimulating hormone (FSH) and luteinizing hormone (LH) for normal ovulation, – if you take these medications in high doses (which I did not but I take such a low dose bc it affects me so easily). So here we are, on a Sunday so I can’t reach my doctor’s office and I’m freaking out that I may of messed everything up! The reason I’m freaking out is bc after I started my period and then started testosterone my period got really light and wasn’t really coming, (this has happened in the past once or twice but I assumed it was the testosterone) but after taking the pred for two days, I noticed today that my period started for real and is extremely heavy! I’ve read everything I can online and cannot seem to figure out the physiology/reason behind taking the testosterone for this month. Was it meant to stop my period and I counteracted it with prednisone and shifted/messed up everything? My AMH hormone levels are 0.884 which the doc said at my age is extremely low and means I don’t have many eggs left compared to most 36Y olds. This why he chose putting me on testosterone instead of a month of birth control. These are the two main pre-IVF options he puts IVF patients on before beginning the injections for those 8-12 days before egg retrieval.
Please help! I just need a yes/no/maybe, will prednisone mess up the goal we are trying to accomplish with taking testosterone? Testosterone is suppose to make follicles, right? So of course I freaked out when I read prednisone prevents your petuitary gland from creating enough FSH. I still have about 3 weeks of taking testosterone so I’m hoping I can still achieve everything without having to start over. I should not of played my own doctor I know this. I should of gone to the ER when I was flaring and tell them everything and let them decide how to treat it. I’m SO sorry I did this, and of course I won’t be taking anymore “new” medications until after we retrieve a bunch of eggs. I’m so glad I found this site….thank you for taking time to do this. I read many of your blogs and you are extremely knowledgeable and I appreciate having somewhere to go on a day like today.

Hi Tracy,
Very respectfully, in my opinion the entire premise of using testosterone during stimulation for IVF is not ideal. The issue at hand is that you have diminished ovarian reserve and in my opinion, the last thing women with DOR need is excessive testosterone. Some testosterone (produced by the ovaries) is needed but too much testosterone can in my opinion compromise egg quality and thus embryo “competency”. I cannot comment on the self-medication aspect of your cycle because I do not agree with the construct thereof, in the first place. At 36y, with an AMH 0r +/- 0,9ng/ml, with an optimal stimulation protocol, you should still be able to produce some good quality eggs and “competent embryos”, but time is likely to be an issue. You cannot afford at this stage getting bogged down and spinning your wheels.
As women age beyond 35Y there is commonly a progressive diminution in the number of eggs left in the ovaries, i.e. diminished ovarian reserve (DOR). In some women, as in your case this occurs more rapidly than in others. So it is that older women as well as those who (regardless of age) have DOR have a reduced potential for IVF success. Much of this is due to the fact that women with DOR tend to have increased production of LH biological activity which can result in excessive LH-induced ovarian male hormone (predominantly testosterone) production which in turn can have a deleterious effect on egg/embryo “competency”.
While it is presently not possible by any means, to reverse DOR, certain ovarian stimulation regimes, by promoting excessive LH production (e.g. short agonist/Lupron- “flare” protocols, clomiphene and Letrozole), can make matters worse. Similarly, the amount/dosage of certain fertility drugs that contain LH/hCG (e.g. Menopur) can have a negative effect on the development of the eggs of women who have DOR and should be limited.
I try to avoid using such protocols/regimes (especially) in older women and those with DOR, favoring instead the use of the agonist/antagonist conversion protocol (A/ACP), a modified, long pituitary down-regulation regime, augmented by adding supplementary human growth hormone (HGH). I further recommend that such women be offered access to embryo banking of PGS (next generation gene sequencing/NGS)-selected normal blastocysts, the subsequent selective transfer of which by allowing them to to capitalize on whatever residual ovarian reserve and egg quality might still exist and thereby “make hay while the sun still shines” could significantly enhance the opportunity to achieve a viable pregnancy
