Hello Dr Sher I have just completed my 2nd ivf which failed due to my 13 follicles in egg collection being empty. The consultant diagnosed me with genuine empty follicle syndrome.
I am 36 years old with a AMH of 15. I had a short protocol this time with ovaleap and fyremadel firstly. All my follicles were roughly between 19-22 mm before egg collection. They triggered me this time with 250 ovitrelle and 1ml of buserelin. I had a reaction to the buserelin as it brought my stomach instantly into a lump. I found it strange how my last scan I literally felt like I was going to pop , however the following morning after I double triggered the night before I woke up to no more pain or uncomfortable bloating. I contacted my nurse and she said it could be due to the follicles being told to stop growing so to speak. But I felt odd how the pain had gone completely.
My previous 1st cycle if ivf was a long protocol. Again they used Ovitrelle 250 and again could only get 1 egg out,the rest where again empty. This one egg resulted in my 21 month old daughter.
They took a blood test after the 1st egg collection and found the trigger shot had absorbed. But not at the normal rate.
This cycle they didn’t take a blood test after and the consultant said that re-triggering after 36 hours would not work. In hindsight I wish I pushed this but due to the shock and groggyness of the drugs. I didn’t push it. Do you think this may have worked?
Do you think I should change the trigger shot or dosage? I don’t have pcos, endo or heavy periods. I have a regular 26-28 cycle. But I only have a 2-3 day cycle now. My husband is 38 and his results have always come back fine.
Any advice would be much appreciated, thank you,
Laura

Frequently, when following vigorous and often repeated flushing of follicles at egg retrieval they fail to yield eggs, it is ascribed to “Empty Follicle Syndrome.” This is a gross misnomer, because all follicles contain eggs. So why were no eggs retrieved from the follicles? Most likely it was because they would/could not yield the eggs they harbored.
This situation is most commonly seen in older women, women who have severely diminished ovarian reserve, and in women with polycystic ovarian syndrome (PCOS). In my opinion it is often preventable when an optimal, individualized and strategic protocol for controlled ovarian stimulation (COS) is employed and the correct timing and dosage is applied to the “hCG trigger shot.”
Normally, following optimal ovarian stimulation, the hCG “trigger shot” is given for the purpose of it triggering meiosis (reproductive division) that is intended to halve the number of chromosomes from 46 to 23 within 32-36 hours. The hCG trigger also enables the egg to signal the “cumulus cells” that bind it firmly to the inner wall of the follicle (through enzymatic activity), to loosen or disperse, so that the egg can detach and readily be captured at egg retrieval (ER).
Ordinarily, normal eggs (and even those with only one or two chromosomal irregularities) will readily detach and be captured with the very first attempt to empty a follicle. Eggs that have several chromosomal numerical abnormalities (i.e., are “complex aneuploid”) are often unable to facilitate this process. This explains why when the egg is complex aneuploid, its follicle will not yield an egg…and why, when it requires repeated flushing of a follicle to harvest an egg, it is highly suggestive of it being aneuploid and thus “incompetent” (i.e., incapable of subsequently propagating a normal embryo).
Older women, women with diminished ovarian reserve, and those with polycystic ovarian syndrome, tend to have more biologically active LH in circulation. LH causes production of male hormone (androgens, predominantly testosterone), by ovarian connective tissue (stroma/theca). A little testosterone is needed for optimal follicle development and for FSH-induced ovogenesis (egg development). Too much LH activity compromises the latter, and eggs so affected are far more likely to be aneuploid following meiosis.
Women with the above conditions have increased LH activity and are thus more likely to produce excessive ovarian testosterone. It follows that sustained, premature elevations in LH or premature luteinization (often referred to as a “premature LH surge”) will prejudice egg development. Such compromised eggs are much more likely to end up being complex aneuploid following the administration of the hCG trigger, leading to fruitless attempts at retrieval and the so called “empty follicle syndrome.”
The developing eggs of women who have increased LH activity (older women, women with diminished ovarian reserve, and those with PCOS) are inordinately vulnerable to the effects of protracted exposure to LH-induced ovarian testosterone. Because of this, the administration of medications that provoke further pituitary LH release (e.g., clomiphene and Letrozole), drugs that contain LH or hCG (e.g., Menopur), or protocols of ovarian stimulation that provoke increased exposure to the woman’s own pituitary LH (e.g., “flare-agonist protocols”) and the use of “late pituitary blockade” (antagonist) protocols can be prejudicial.
The importance of individualizing COS protocol selection, precision with regard to the dosage and type of hCG trigger used, and the timing of its administration in such cases cannot be overstated. The ideal dosage of urinary-derived hCG (hCG-u) such as Novarel, Pregnyl and Profasi is 10,000U. When recombinant DNA-derived hCG (hCG-r) such as Ovidrel is used, the optimal dosage is 500mcg. A lower dosage of hCG can, by compromising meiosis, increase the risk of egg aneuploidy, and thus of IVF outcome.
There is in my opinion no such condition as “Empty Follicle Syndrome.” All follicles contain eggs. Failure to access those eggs at ER can often be a result of the protocol used for controlled ovarian stimulation.

Name: Tracy W
In 2020 (age 42), we had 2 natural pregnancies at 6-8 weeks and miscarried naturally. In 2021, we tried IVF, we had 2 cycles that gave us 11 embryos, only 1 grew and it was abnormal. In July of 2022, we decided to use an egg donor and travel to South Africa to do this. We did a fresh transfer with 1 embryo and froze the rest. All 11 were graded really high but untested. I got pregnant but at my 1st & 2nd ultrasound, there was just an empty sack. I miscarried around 10 weeks after a D&C. In Nov we tried a FET again with 2 embryos. Lining was too thin, 6mm so they increased my estrogen to 6mg orally in AM and 6mg in PM. In 2 days it jumped to 7.3mm and we transferred 2 but they didn’t stick. My doctor then suggested a hysteroscopy and testing the embryos. We tested and have 3 normal embryos (out of 7). The hysteroscopy was performed on day CD 17 (Jan 24 2023) by my OBGYN here in the US and he removed some adhesions. We tried again recently in March 2023 but my lining only got to 5.6mm after 3 extra days with added estrogen (6mg in AM and 6mg in PM plus I was taking a patch every other day from the beginning) so we had to cancel. Why would my lining get thinner after a hysteroscopy and with added estrogen? My SA doctor thinks I need another hysteroscopy between day 1-10 of my cycle and wants to test for chronic endometritis. My OBGYN here doesn’t think I would benefit from another one. I’m also having issues hearing back from him on whether or not he had tested for chronic endometritis. What would you suggest at this point?
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:
Examples include;
“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”.

Hi Dr. Sher , I have scheduled a robotic assisted laparoscopy to remove the endometriomas off of my ovaries based on your advice last year . My procedure description is “robotic assisted laparoscopy , lysis of adhesions , resection / fulgerartion of endometriosis, bilateral cysectomy , chromopertubation, and resection of villar nodule . My question is do you think that is an appropriate technique? I read so many posts against that kind of heat , and I don’t necessarily know if “burning “ it out would help my chances of ivf success in the future. This is being performed by a doctor recommended by my fertility doctor . I’m 40 years old with 3 failed cycles behind me . Any thoughts on this style of surgery for endometriosis? I have pain sometimes but I am mostly doing this to get the cysts off my ovaries for future IVF . Thank for your time , Mindy D .
I think we should talk!
Please call my assistant, Patti Converse at 702-533-2691 and set up an online consultation with me to discuss!
When women with infertility due to endometriosis seek treatment, they are all too often advised to first try ovarian stimulation (ovulation Induction) with intrauterine insemination (IUI) ………as if to say that this would be just as likely to result in a baby as would in vitro fertilization (IVF). Nothing could be further from reality It is time to set the record straight. And hence this communication!
Bear in mind that the cost of treatment comprises both financial and emotional components and that it is the cost of having a baby rather than cost of a procedure. Then consider the fact that regardless of her age or the severity of the condition, women with infertility due to endometriosis are several fold more likely to have a baby per treatment cycle of IVF than with IUI. It follows that there is a distinct advantage in doing IVF first, rather than as a last resort.
So then, why is it that ovulation induction with or without IUI is routinely offered proposed preferentially to women with mild to moderately severe endometriosis? Could it in part be due to the fact that most practicing doctors do not provide IVF services but are indeed remunerated for ovarian stimulation and IUI services and are thus economically incentivized to offer IUI as a first line approach? Or is because of the often erroneous belief that the use of fertility drugs will in all cases induce the release (ovulation) of multiple eggs at a time and thereby increase the chance of a pregnancy. The truth however is that while normally ovulating women (the majority of women who have mild to moderately severe endometriosis) respond to ovarian stimulation with fertility drugs by forming multiple follicles, they rarely ovulate > 1 (or at most 2) egg at a time. This is because such women usually only develop a single dominant follicle which upon ovulating leaves the others intact. This is the reason why normally ovulating women who undergo ovulation induction usually will not experience improved pregnancy potential, nor will they have a marked increase in multiple pregnancies. Conversely, non-ovulating women (as well as those with dysfunctional ovulation) who undergo ovulation induction, almost always develop multiple large follicles that tend to ovulate in unison. This increases the potential to conceive along with an increased risk multiple pregnancies.
So let me take a stab at explaining why IVF is more successful than IUI or surgical correction in the treatment of endometriosis-related infertility:
I am not suggesting that all women with infertility-related endometriosis should automatically resort to IVF. Quite to the contrary…. In spite of having reduced fertility potential, many women with mild to moderate endometriosis can and do go on to conceive on their own (without treatment). It is just that the chance of this happening is so is much lower than normal.
IN SUMMARY: For young ovulating women (< 35 years of age ) with endometriosis, who have normal reproductive anatomy and have fertile male partners, expectant treatment is often preferable to IUI or IVF. However, for older women, women who (regardless of their age) have any additional factor (e.g. pelvic adhesions, ovarian endometriomas, male infertility, IID or diminished ovarian reserve-DOR) IVF should be the primary treatment of choice.

Name: Alexandra C
Dear doctor Sher,
I am 33 years old and my husband is 36. After 5 months of trying to conceive (that was back in November 2022), we decided to visit a fertility specialist in
Switzerland where we are currently located. He ran the basic hormonal exams on the 4th day of my cycle (4th day from flow, 5th day from light spotting) identifying a low AMH (0.56 ng/ml). For reference my estradiol levels were 723 pmol/l, my FSH was 4.5 IU (I know high estradiol could have suppressed this hormone) and my LH was 7.4 IU. He did not check for testosterone or DHEA levels. AFC on day 8 of the cycle was 5 (only in one ovary – I should probably mention that only one ovary has a normal size while the other is small which I know is another indication of a reduced ovarian reserve). I did ovulate slightly earlier than what I am used to that month and had my period earlier as well. Ovulation was confirmed on day 10 (through ovulation kits I have confirmed that I am ovulating between the 11th-14th day). Follicle was of mature size. Progesterone levels after ovulation were normal (luteal phase duration is also normal – 15-16 days long).Thickness of uterus was good as well. In the following months, I also did a hysteroscopy and everything appeared normal. I should probably mention that my husband had 1% of normal sperm morphology (everything else is good). Thus, we decided to proceed with IVF and more precisely, ICSI.
My doctor had me on Primolut n for 5 days and on the 4th day after I stopped taking it, I got my period. On the second day of my period, I started taking Pergoveris
350 IU per day. I took it for 3 days and then I went in for blood work and an ultrasound (STIM DAY4). The ultrasound showed only 4 very small follicles, two in each
ovary. The doctor commented that they were still small and that the bloodwork corresponded to their small size. He augmented the dose to 400 IU per day for 3 days again. On STIM DAY7, I went again for bloodwork and an ultrasound. Still he could only see 4 follicles (13.5 mm, 10.8 mm, 10.9 mm, 9.8 mm). Oestradiol levels were around 1230 pmol/l while LH levels were more than 9 IU. On that day he increased the dose of Pergoveris to 450 IU and on that night I started taking Cetrotide 0,25 mg. Two days after, I went for another round of blood work and ultrasound (STIM DAY9) where he told me that estradiol was increased but did not mention how much. Ultrasound showed 5 follicles this time (two smaller than 10 mm, 1 at 11 mm, 1 at 12.5 mm and one at 18.5 mm). Thus, on that day I took another 450 IU of Pergoveris during the day, a Cetrotide 0.25 mg and Ovitrelle 250 μg during the night. He advised us to go through with the retrieval of eggs just to see also their quality, although in reality there was only one mature follicle (he also mentioned that my uterus was ready). I did go through the retrieval yesterday (36 hours after trigger shot) and they informed me that they had collected two eggs but both of them were immature. We were surprised as one of the follicles seemed to have had the appropriate size. The day of the retrieval would have been day 11 of stimulation. On day 10, I received no hormones.
I apologize for not having more details with regards to my blood exams but this is what I remember from what he had shown me at the office. I don’t have any of the blood work results from the ovarian stimulation phase. I am not sure if the protocol was the right one for my case or if I have an egg quality problem along with the poor response and the problem of the low ovarian reserve. I am starting to believe that I am a lost cause and that I should not proceed with another round of IVF. I always wanted to have at least one biological kid but I also wanted to adopt. We are not considering donor eggs. I would very much appreciate your expert opinion on my case. I did read your response here https://sherfertilitysolutions.com/ask-our-doctors/egg-immaturity/ and if I understood
correctly there were some things that the doctor could have done differently. Therefore, my question is am I a lost cause or some modifications to the protocol could bring better results?
P.S. Doctor mentioned that I may be a poor responder because the FSH receptors on my ovaries do not communicate properly with my pituitary gland which is shown from me not responding to high doses of FSH. Could that be a possibility and is there anything that can be done about it?
Also, I have been taking these vitamins – http://www.fol-ino.ch/women/fr/index.php – that my doctor prescribed but I wonder If I should have been taking something else (CoEnzyme Q10 and DHEA along with folic acid and Vitamin D?) as they seem to be appropriate only for people with PCOS. I have taken them for 2.5 months.
Thank you in advance for your response and thank you for taking the time to read my very long email.
Kind regards,
Alexandra
Hi Alexandra,
Yes indeed, based on your AMH blood level, you have prematurely developed diminished ovarian reserve (DOR) and this means you have very much reduced egg population (which cannot be replenished) and accordingly will propagate very few follicles. In addition, women with DOR often have an adverse ovarian hormonal environment that is not condusive to optimal egg development during ovarian stimulation. To avoid this you will need an individualized strategic approach to ovarian stimulation. A “Recipe / “one size fits alll” approach will likely not work (see below). However, because you are still relatively young, given the ideal protocol and implementation thereof, you should be able to do much better and yes, have a baby through IVF. The progressive decline in ovarian reserve will continue and can accelerate, so time is of the essence. You simply do not have time to waste on other alternatives than IVF.
You are absolutely NOT a hopeless case. In fact my practice is largely made up of patients like you who=se chances are even poorer because they are usually older.
Good luck!
Geoff Sher

__________________________________________________________________________________
It is primarily the egg (rather than the sperm) that determines the chromosomal integrity (karyotype) of the embryo, the most important determinant of egg/embryo competency”. A “competent” egg is therefore one that has a normal karyotype and has the best potential to propagate a “competent” embryo. In turn, a “competent embryo is one that possesses the highest potential to implant and develop into a normal, healthy, baby.
When it comes to reproductive performance, humans are the least efficient of all mammals. Even in young women under 35y, at best only 2 out of 3 eggs are chromosomally numerically normal (euploid). The remainder will have an irregular number of chromosomes (aneuploid) and are thus “incompetent”. The incidence of egg aneuploidy increases with age such by age 39 years, 3 in 4 are “competent”, and by the mid-forties, at best one in 10 are likely to be aneuploid. The fertilization of an aneuploid egg will inevitably lead to embryo aneuploidy (“incompetence”). As previously stated, an aneuploid embryo cannot propagate a normal pregnancy
Within 38-42 hours of the initiation of the spontaneous pre-ovulatory luteinizing hormone (LH) surge (and also following administration of the human chorionic gonadotropin (hCG) “trigger” shot, given to induce egg maturation after ovarian stimulation with fertility drugs), the egg embarks on a rapid maturational process that involves halving of its 46 chromosomes to 23. During this process, (known as meiosis) 23 chromosomes are retained within the nucleus of the egg while the remaining 23 chromosomes are expelled in a membrane envelopment, from the egg nucleus. This small structure known as the polar body, comes to lie immediately below the “shell” of the egg (the zona pellucida) and is known as the 1st polar body or PB-1. The sperm, in the process of its maturation also undergoes meiosis divides into two separate functional gametes, each containing 23 chromosomes (half its original number of 46 chromosomes). With subsequent fertilization, the 23 chromosomes of the egg now fuse with the 23 chromosomes of the mature sperm resulting in the development of an embryo with 46 chromosomes (the normal human genome) comprising a combination of the genetic material from both partners. For the embryo to have exactly 46 chromosomes (the euploid number), both the mature egg and mature spermatozoon must contain exactly 23 chromosomes. Only such euploid embryos are “competent” (capable of developing into healthy babies). Those with an irregular number of chromosomes (aneuploid embryos) are “incompetent” and are incapable of propagating healthy babies. While embryo “incompetence” can result from either egg or sperm aneuploidy, it usually stems from egg aneuploidy. However, in cases of moderate or severe male factor infertility, the sperm’s contribution to aneuploidy of the embryo can be significantly greater.
While embryo ploidy (numerical chromosomal integrity) is not the only determinant of its “competency, it is by far the most important and in fact is a rate-limiting factor in human reproduction. It is causal in the vast majority of cases of “failed nidation which in turn is responsible for most cases of a failed pregnancy (natural or assisted) and causes most sporadic early pregnancy losses (both chemical gestations and miscarriages) as well as many chromosomal birth defects such as Turner syndrome (X-monosomy ) Down syndrome (trisomy 21) and Edward syndrome (trisomy 18) .
In most cases, embryos that develop too slowly as well as those that grow too fast (i.e. ones that by day 3 post-fertilization comprise fewer than 6 cells or more than 9 cells) and/or embryos that contain cell debris or “fragments” are usually aneuploid and are thus unable to propagate a healthy pregnancy (“incompetent”). Additionally, embryos that fail to survive in culture to the blastocyst stage are also almost always aneuploid/”incompetent”.
At a certain point in the later stage of a woman’s reproductive career, the number of remaining eggs in her ovaries falls below a certain threshold, upon which she is unable to respond optimally to fertility drugs. Often times this is signaled by a rising day 3 basal blood follicle stimulating hormone (FSH) level (>9.0MIU/ml) and a falling blood anti-Mullerian hormone (AMH) level (<2.0ng/ml or <15nmol/L). Such women who have diminished ovarian reserve (DOR) produce fewer eggs in response to ovarian stimulation. While DOR is most commonly encountered in women over 40 years of age it can and indeed also can occur in much younger women.
A few important (but often overlooked concepts should be considered in this regard:
The introduction of preimplantation genetic testing/screening (PGT/PGS) for e permits identification of all the chromosomes in the egg and embryo (full karyotyping) allowing for the identification of the most “competent” (euploid) embryos for selective transfer to the uterus. This vastly improves the efficiency and success of the IVF process and renders us fare better equipped us to manage older women and those who regardless of their age, have DOR.
