“Triggering” Egg Maturation in IVF: Comparing urine-derived hCG, Recombinant DNA-hCG and GnRH-agonist

Ideal egg development sets the scene for optimal egg maturation that occurs 36-42h prior to ovulation or egg retrieval. Without prior optimal egg development (ovogenesis), egg maturation will be dysfunctional and most eggs will be rendered “incompetent” and unable upon fertilization to propagate viable embryos. In IVF, optimal ovogenesis requires the selection and implementation of an individualized approach to controlled ovaria stimulation (COS). Thereupon, at the ideal time, maturational division of the egg’s chromosomes (i.e. meiosis) is “triggered” through the administration of hCG or an agonist such as Lupron, which induces an LH surge. The dosage and timing of the “trigger shot” profoundly affects the efficiency of meiosis, the potential to yield “competent” (euploid) mature (M2) eggs, and as such represents a rate-limiting step in the IVF process.

Triggering meiosis with Urine-derived hCG (Pregnyl/Profasi/Novarel) versus recombinant hCG (Ovidrel): Until quite recently, the standard method used to “trigger” egg maturation was through the administration of 10,000 units of hCGu. Subsequently, a DNA recombinant form of hCGr (Ovidrel) was introduced and marketed in 250 mcg doses. But clinical experience strongly suggests that 250 mcg of Ovidrel is most likely not equivalent in biological potency to 10,000 units of hCG.  It probably only has 50%-70% of the potency of a 10,000U dose of hCGu and as such might not be sufficient to fully promote meiosis, especially in cases where the woman has numerous follicles. For this reason, I firmly believe that when hCGr  is selected as the “trigger shot” the dosage should best  be doubled to 500 mcg at which dosage it will probably have an equivalent effect on promoting meiosis as would 10,000 units of hCGu. Having said this, it is my personal opinion that it is unnecessary to supplant hCGu with hCGr since the latter is considerably more expensive and is probably no more biopotent than the latter.  

Some clinicians, when faced with a risk of OHSS developing will deliberately elect to reduce the dosage of hCG administered as a trigger in the hope that by doing so the risk of critical OHSS developing will be lowered. It is my opinion, that such an approach is not optimal because a low dose of hCG (e.g., 5000 units, hCGu or 25omcg hCGr) is likely inadequate to optimize the efficiency of meiosis  particularly when it comes to cases such as this where there are  numerous follicles.  

It has been suggested that the preferential use of an “agonist (Lupron) trigger” in women at risk of developing severe ovarian hyperstimulation syndrome could potentially reduce the risk of the condition becoming critical and thereby placing the woman at risk of developing life-endangering complications. It is with this in mind that many RE’s prefer to trigger meiosis by way of an “agonist (Lupron) trigger rather than through the use of hCG.  The agonist promptly causes the woman’s pituitary gland to expunge a large amount of LH over a short period of time and it is this LH “surge” that triggers meiosis. The problem with using this approach, in my opinion, is that it is hard to predict how much LH will be released in by the pituitary gland.  For this reason, I personally prefer to use hCGu for the trigger, even in cases of ovarian hyper stimulation with one important proviso – she underwent “prolonged coasting” in order to reduce the risk of critical OHSS, prior to the 10,000 unit hCGu “ trigger”.

The timing of the “trigger shot” to initiate meiosis:  This should coincide with the majority of ovarian follicles being >15 mm in mean diameter with several follicles having reached 18-22 mm. Follicles of larger than 22 mm will usually harbor overdeveloped eggs which in turn will usually fail to produce good quality eggs. Conversely, follicles less than 15 mm will usually harbor underdeveloped eggs that are more likely to be aneuploid and incompetent following the “trigger”.  




Dear Dr Sher,
Thank you for all your posts and your answers to many questions. I really need your insights for my most recent devastating cycle which failed so mysteriously- because everything looked good on paper.
I started estrace pills(6mg/day)and testosterone gel on CD3, which lasted for about a month, immediately followed by the stim.
The protocol my doctor used is as follows:
day 1&day2 AM Gonal-F 175iu,+omnitrope1/2 vial+dexamethasone 1 pill
PM clomiphene 1pill +menopur 75iu, day 3 to day 10 : AM GonalF 250iu+ omnitrope 1/2 vial+ dexamethasone 1pill PM clomiphene 1pill + menopur 75iu

Citrotide was added to the protocol since day 5, but i was advised to only do 1/7-1/8 of a vial each day in the AM all the way to before trigger. The last citrotide shot was increased to 1/2 vial before trigger.

The trigger was given on the 11th day at 7:45 pm . I was instructed to do a combination of Lupron 40iu + Ovidrel 250.

The retrieval day was at 6:30am on the 13th day. Tragically, 5 of the expected follicles were empty and the only 2 collected were GV and M1. So in the end NOT one mature egg was obtained.

I was shattered.

As I was going through the cycle I was always told everything looked good- my estrodial growth, my follicle growth, and I was told I responded well to the drugs. My estrodial was about 2400 one day before trigger. My baseline AFC was 8ish , after the stim the doctor was expecting 7ish eggs . Follicle sizes before trigger were: 14+16 (L) ,14+16×4 (R).

Dr Sher could you please tell me in your opinion what was wrong? Could you please point out what in your opinion was bad in this treatment? I did take DHEA low dose on/off more than 2 months bofore the cycle , was that inappropriate as well? I really really appreciate your opinions and help.
PS, my baseline FSH was 5 , LH 2.8 AMH 1.66, AFC7-8 age 39


Dr. Geoffrey Sher

Very respectfully, I would need much more information to comment authoritatively. What I can tell you however, is that aside from age and ovarian reserve, in my opinion, the protocol used for ovarian stimulation is the most important consideration, and respectfully (again) the overall protocol used in your case was in my opinion, not optimal. I also find fault with the use of testosterone supplementation as well as DHEA (see below).

One of the commonest questions asked by patients undergoing IVF relates to the likelihood of their eggs fertilizing and the likely “quality of their embryos. This is also one of the most difficult questions to answer. On the one hand many factors that profoundly influence egg quality; such as the genetic recruitment of eggs for use in an upcoming cycle, the woman’s age and her ovarian reserve, are our outside of our control. On the other hand the protocol for controlled ovarian stimulation (COS) can also profoundly influence egg/embryo development and this is indeed chosen by the treating physician.

First; it should be understood that the most important determinant of fertilization potential, embryo development and blastocyst generation, is “competency” of the embryo that is mostly affected by the numerical chromosomal integrity (ploidy) of the egg. While sperm quality does play a role, in the absence of moderate to severe sperm dysfunction this is (moderate or severe male factor infertility a relatively small one). Human eggs have the highest rate of numerical chromosomal irregularities (aneuploidy) of all mammals. In fact only about half the eggs of women in their twenties or early thirties, have the required number of chromosomes (euploid), without which upon fertilization they cannot propagate a normal pregnancy. As the woman advances into and beyond her mid-thirties, the percentage of eggs euploid eggs declines progressively such that by the age of 40 years, only about one out of six are likely to be chromosomally normal. By her mid-only about forties one in ten of her eggs will be euploid and by 4r years of age, fewer than one in twenty will be euploid.

Second; embryos that fail to develop into blastocysts are almost always aneuploid and not worthy of being transferred to the uterus because they will either not implant, will miscarry or could even result in a chromosomally abnormal baby (e.g. Down syndrome). However, it is incorrect to assume that all embryos reaching the blastocyst stage are will be euploid (“competent”). ). It is true that since many aneuploid embryos are lost during development and that those failing to survive to the blastocyst stage are far more likely to be competent than are earlier (cleaved) embryos. What is also true is that the older the woman who produced the eggs, the less likely it is that a given blastocyst will be “competent”. As an example, a morphologically pristine blastocyst derived from the egg of a 30 year old woman would have about a 50:50 chance of being euploid and such a microscopically normal embryo would have 25%-30% chance of propagating a healthy, normal baby, while a microscopically comparable blastocyst derived through fertilization of the eggs from a 40 year old, would be about half as likely to be euploid and/or propagate a healthy baby and by 45 years of age…less than 5%. .

While the effect of species on the potential of eggs to be euploid at ovulation is genetically preordained and nothing we do can alter this equation, there is unfortunately a lot we can (often unwittingly) do to worsen the situation by selecting a suboptimal protocol of controlled ovarian stimulation (COS). This, by creating an adverse intraovarian hormonal environment will often disrupt normal egg development and lead to a higher incidence of egg aneuploidy than otherwise might have occurred. Older women, women with diminished ovarian reserve (DOR) and those with polycystic ovarian syndrome are especially vulnerable in this regard.

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 (tissue surrounding ovarian follicles) during the pre-ovulatory phase of the cycle enhance late follicle development, estrogen production by the granulosa 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 COS protocols should be individualized and geared toward optimizing follicle growth and development time while avoiding excessive ovarian androgen (testosterone) production and that the hCG “trigger shot” should be carefully timed.

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.

1. 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.

2. 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.

3. The agonist/antagonist conversion protocol (A/ACP):
With the A/ACP, GnRH antagonist (Ganirelix, Cetrotide, and Orgalutron) is administered by daily injection from the onset of COS. The A/ACP COS-cycle is launched with the woman coming off a monophasic birth control pill that was administered starting in the 1st 5 days of the preceding cycle and continued for at least 10 days. The BCP is then overlapped with an agonist (e.g. Lupron/buserelin) for three days, whereupon the BCP is stopped and the agonist (Lupron/buserelin) is continued until the onset of menstruation. At or around this point, the agonist (Lupron/Buserelin) is supplanted by an antagonist (Cetrotide/Ganirelix/Orgalutron) and concurrently COS is initiated using an FSH-dominant bias (mainly Follistim/Gonal-F/ Puregon + a small dosage of a menotropins such as Menopur). The combined antagonist/gonadotropin therapy is continued until the hCG trigger. For the reasons cited above, I prescribe some form of the A/ACP for my older IVF patients and those with DOR. ]
A/ACP with estrogen priming: The A/ACP can be modified for women with very severe DOR through incorporation of “estrogen priming”. We have reported on the fact that the administration of intramuscular estradiol starting about a week prior to commencement of COS. This often markedly enhances ovarian response (presumably by “estrogen priming” enhancing the sensitivity of ovarian FSH-receptors).
There is one draw-back to the use of the A/ACP. This is the fact that prolonged administration of GnRH antagonist throughout the stimulation phase of the COS cycle compromises the predictive use of serial plasma estradiol measurements as an indication of ovarian response to COH. The blood estradiol levels tend to be much lower in comparison with cases where GnRHa alone is used.The reason for the lower blood concentration of estradiol seen with prolonged exposure to GnRH-antagonist might be due to the result of subtle, antagonist-induced alterations in the configuration of the estradiol molecule, such that currently available commercial test used to measure estradiol levels are rendered less sensitive/specific. Accordingly, when the A/ACP protocols are employed, we rely much more heavily on the measurement of follicle growth by ultrasound than on the estradiol levels. Because of this downside, I refrain from using this approach in “high responders” who may be at risk of developing of severe ovarian hyperstimulation syndrome (OHSS) and in whom the accurate measurement of plasma estradiol plays a very important role in the safe management of their COS cycles.
4. The “Trigger”: hCG (Profasi/Pregnyl/Novarel) versus agonist (Lupron/Buserelin/Superfact):
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) can obviate this effect

Sher-Fertility Solutions (SFS) will be officially launched in April 2019. Through SFS I will provide fertility consultations (via SKYPE) to an ever-growing number of patients (from >40 countries) with complex Reproductive Dysfunction (RD) who seek access to my input and guidance.

In the past, I have limited my consultations with patients from afar to those who expressed a willingness to travel to Las Vegas for treatment by me. But now with the “birth” of SFS, all this is about to change. With one notable exception I will, as of April, 2019, no longer be conducting and performing hands-on IVF treatments. Rather, I will focus on providing SKYPE consultations and guidance to as many patients as possible. The one important exception will apply to approximately 1,000 existing patients who, following IVF previously performed by me, have remaining eggs or embryos stored (cryopreserved) at SIRM-LV and wish for me to perform their Frozen Embryo Transfers (FETs). I have agreed to accommodate such patients…..but only through August, 2019.

Patients will have ready access online, to SFS: by going to http://www.SherIVF.com; by phone (1-800-780-7437 or 702-533-2691) and via email (sher@sherivf.com or concierge@sherIVF.com). A onetime fee of $400.00, will provide enrollees with access to: a full review of all their medical records (+ assistance in requisitioning additional records, as needed); a comprehensive initial 1 hour, SKYPE consultation with me; additional SKYPE consultations (as might be required); a written medical report (which will include a recommended plan of action) that you can share with a Physician(s) of choice. I would, subject to your approval and a request by such Physician(s), also be willing to discuss your case with him/her/them. I will in due course post on my website, a list of Fertility Physicians in key locations all over the United States and abroad, whom I endorse and to whom I would be willing to direct SFS patients for subsequent treatment.

I have good news for those of you who are interested in traveling to Las Vegas for IVF. Dr Russel Foulk, Medical Director of SIRM-LV has expressed a willingness to be receptive to, treatment plans that I recommend for SFS patients Moreover, Dr Foulk has graciously agreed to interact with me during such treatments. I highly recommend Dr Foulk to those of you who, following consultation with me, wish to have me remain involved in the implementation of your treatment. This having been said, the final say in any management decision is always up to the treating physician.

It is both my objective and commitment to serve as a resource to SFS patients on complex RD issues such as: Unexplained IVF failure; Recurrent Pregnancy loss (RPL); Immunologic Implantation Dysfunction-IID; Genetic/chromosomal issues; effects of Diminished Ovarian Reserve (DOR) and advancing age on reproductive performance, etc.

I hope to ultimately expand the National and International reach of SFS, through my website (www.sherIVF.com) , through online webinars as well as Town hall- type consumer-based seminars, workshops and through social media. At the same time I will continue blogging on my website and doing bi-weekly Live-feed Facebook presentations (at “Dr Geoffrey Sher”) on a variety of subjects and topical issues.

For me this is a very exciting venture. Please become part of the SFS family and help spread the word!

I was very recently greatly honored in receiving an award by the prestigious; International Association of Top Professionals (IAOTP). For more information, go to the press release on my website, http://www.sherIVF.com .


I’ve done 3 rounds of IVF and have had difficulty retrieving eggs in all 3 cycles. I’m 36 years old with a 3.9 AMH level. My protocol was 150u of Menopur, 150u or 175u of Gonal F (went up to 175u in the 3rd cycle) and 5u of Lupron while on stims. I start with 10u of Lupron when I start the birth control pill and decrease it to 5u when stims are introduced. For cycles 1 and 3, my trigger has been Ovidrel and for cycle 2, my trigger was Pregnyl. First cycle yielded 2 eggs (expecting 8), second cycle yielded 11 eggs (expecting 13-15) and third cycle yielded 4 eggs (expecting 15-17). Each time, we get far fewer eggs than we’re expecting. Estradiol levels have been good too – 3400 in cycle 2, 3641 in cycle 3. Basically, everything looks great on paper and then we have such poor results during retrievals. Do you have any thoughts on what is causing the retrieval problems? Do you think it has to do with the drug protocol or trigger shot? I’ve been on stims for 9 days in each cycle.

Dr. Geoffrey Sher

Hi Abbey,

In my opinion, your protocol for ovarian stimulation needs to be reviewed and revised. This is likely where the problem lies. It is my opinion that you might be getting too low a dosage of Ovidrel or Pregnyl.

Here is the protocol I advise for women, who have adequate ovarian reserve.
My advice is to use a long pituitary down regulation protocol starting on a BCP, and overlapping it with Lupron 10U daily for three (3) days and then stopping the BCP but continuing on Lupron 10u daily (in my opinion 20U daily is too much) and await a period (which should ensue within 5-7 days of stopping the BCP). At that point an US examination is done along with a baseline measurement of blood estradiol to exclude a functional ovarian cyst and simultaneously, the Lupron dosage is reduced to 5U daily to be continued until the hCG (10,000u) trigger. An FSH-dominant gonadotropin such as Follistim, Puregon or Gonal-f daily is started with the period for 2 days and then the gonadotropin dosage is reduced and a small amount of menotropin (Menopur—no more than 75U daily) is added. This is continued until US and blood estradiol levels indicate that the hCG trigger be given, whereupon an ER is done 36h later. I personally would advise against using Lupron in “flare protocol” arrangement (where the Lupron commences with the onset of gonadotropin administration.

I am on my 4th cycle and have always had 250mg of ovidril as my trigger. I am 41yrs old with Amh of 10 ( which I’m sure has reduced after 2 failed cycles in a row) I have only had 3 mature eggs from my last 2 cycles. ( 1st cycle elenova/menopur 250mg & 2nd cycle gonal f 275mg/luverus)
This cycle I am on decapeptyl & 450 menopur with 250mg ovidril trigger. Would you suggest I ask my for a double trigger? I am doing ivf in Australia

Dr. Geoffrey Sher

In my opinion, 250mcg Ovidrel is not an optimal trigger dosage. I believe it should be doubled.
