Hi Dr Sher,
I was wondering if you could tell me if you think that I have any chance of getting pregnant with a 3-day transfer off all embryos produced during Ivf given the following information:
-I am now 43 years old
-My fsh is 10.4
-My amh is .9
-My antral follicle count is 10
-I will be on Clomid and Gonal F with Ganirelix and then hcg trigger.
-I had twins at 39 with a follistim iui
Just curious if you think this is worth pursuing or not.
Yes I dobut very respectfully, in my opinion, the use of clomiphene (in any combination)by increasing pituitary output of LH is not ideal for women undergoing IVF in general and especially not for woman with diminished ovarian reserve (DOR) and who are older.
In my opinion, the protocol used for ovarian stimulation, against the backdrop of age, and ovarian reserve are the drivers of egg quality and egg quality is the most important factor affecting embryo “competency”.
Older women as well as those who (regardless of age) have diminished ovarian reserve (DOR) tend to produce fewer and less “competent” eggs, the main reason for reduced IVF success in such cases. The compromised outcome is largely due to the fact that such women tend to have increased LH biological activity which often results in excessive LH-induced ovarian testosterone production which in turn can have a deleterious effect on egg/embryo “competency”.
Certain ovarian stimulation regimes either promote excessive LH production (e.g. short agonist/Lupron- “flare” protocols, clomiphene and Letrozole), augment LH/hCG delivered through additional administration (e.g. high dosage menotropins such as Menopur), or fail to protect against body’s own/self-produced LH (e.g. late antagonist protocols where drugs such as Ganirelix/Cetrotide/Orgalutron that are first administered 6-7 days after ovarian stimulation has commenced).
I try to avoid using such protocols/regimes (especially) in older women and those with DOR, favoring instead the use of a modified, long pituitary down-regulation protocol (the agonist/antagonist conversion protocol-A/ACP) augmented by adding supplementary human growth hormone (HGH). I further recommend Staggered IVF with embryo banking of PGS (next generation gene sequencing/NGS)-normal blastocysts in such cases. This type of approach will in my opinion, optimize the chance of a viable pregnancy per embryo transfer procedure and provide an opportunity to capitalize on whatever residual ovarian reserve and egg quality still exists, allowing the chance to “make hay while the sun still shines”.

Hi Dr. Sher,
Thank you for this opportunity to ask questions.
My wife (just turned 36, we already have a 5 year old boy) is now pregnant following IUI #20, after 3 IVF cycles that resulted in 2 MCs and 1 biochem. She is pretty sure she ovulated late afternoon on the day of the IUI (Nov 27). Her first bHCG result on 12/12 (DPO15) was 60. The 2nd one today (12/14, DPO17) was 95. According to what I read (mainly papers from Human Repro like Poikkeus 2002, Bjercke 1999 and Sugantha 2000), there is still hope but not too much of it. I would be very grateful if you could let me know what your own experience is with such numbers.
Thank you very much.
Very guarded optimism here Jeff!
Repeat the hCG blood test again in 2 days to see if it doubles.

I forgot to mention one thing:
The morning of my retrieval, my partner brought in a half hour fresh semen sample and the jar was closed, but slipped from my hands and dropped onto the desk about a foot or two when I handed it to the front desk. Nothing leaked out. The pre-processing sperm report showed: 0.9cc and 50M/cc, motility 53% and progression 2-3 and the post processing showed: 0.4cc, 12M/cc, motility 93% and progression 3. Do you think it being dropped had any impact and do you think the post processing numbers were still ok to have been able to fertilize the egg? Do you think it is possible that there could have been a lab error and if so if there is a way to go about finding out? Thank you for your time.
It would have no ill-effects whatsoever.
Good luck and Merry Xmas!

Hi Dr. Sher,
I am a 40 year old female who just had my first IVF last month for embryo banking only and it failed. I’m shocked this happened since my Day 3 stats were: FSH-8.11 E2:61.1 LH: 7.27 AMH: 4.42 Inhibin B 175.0 ERS 16 and my partner, age 34, semen analysis result was: volume: 1.7 ml 39.5M/ml 71% motile Strict morphology 4.5% normal form . The doc said we both had EXCELLENT numbers. I had 18 antral follicles (9 on each side) seen on US on Day 3. I was given an Antagon cycle and put on Gonal F 300 and Menopur 75(2 of them a night) and then every few days the doc decreased these meds and started cetrotide. I was stimulated for 11 days and my trigger was 1cc of Lupron and also given 0.3cc Novarel. I had a good response to all of the meds. My estradiol levels were measured a few times during the 11 days and the numbers were: 1177, 1666 and 5477.0,pg/mL three days before extraction. My final US follicle measurements I have to ask for , but the measure for them four days before retrieval was: Right ovary: 7/13,14,18,13,14,13,11 mm, Left ovary: 10/14,13,17,22,19,18,17,17,16,17 mm, Doc extracted 22 eggs, 15 mature. Embryologist summary: 4 2pn, 9 M2 rescue ICSI, none made it to day 5. On first day 4 fertilized 2PN and 11 had to be rescue ICSI. Day 2 showed from the 4 2pn ( 6c, 2c,2pn,1c) and the 11 rescue ICSi (5 at 2pn,4 at 3pn, 1 at 4pn and 1 at zero pn. Day 3 and 4 the embryologist did not check them?as there are no notes for those days. Day 5 showed 7c, 3c, 2c, complete fragment, 3c, 2c, 2c, 1c and day 6 says: No blasts. made on day 6 and 9 embryos were discarded. Do you know why I ended up with ZERO embryos, being that my partner and I had great fertility testing results and 15 mature eggs were extracted?
No doubt that age plays a significant role but so does the protocol used for ovarian stimulation. Also, in my opinion, a Lupron trigger is also ill advised…see below.
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. Failure to “trigger” with 10,000U hCGu or 500mcg hCGr, will in my opinion increase the likelihood of disorderly meiosis, “incompetent (aneuploid) eggs” and the risk of follicles not yielding eggs at egg retrieval (“empty follicles”). 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 hyperstimulation hyperstimulated, with one important proviso…that being that is 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”.
In my opinion, the protocol used for ovarian stimulation, against the backdrop of age, and ovarian reserve are the drivers of egg quality and egg quality is the most important factor affecting embryo “competency”.
Older women) tend to produce fewer and less “competent” eggs, the main reason for reduced IVF success in such cases. The compromised outcome is largely due to the fact that such women tend to have increased LH biological activity which often results in excessive LH-induced ovarian testosterone production which in turn can have a deleterious effect on egg/embryo “competency”.
Certain ovarian stimulation regimes either promote excessive LH production (e.g. short agonist/Lupron- “flare” protocols, clomiphene and Letrozole), augment LH/hCG delivered through additional administration (e.g. high dosage menotropins such as Menopur), or fail to protect against body’s own/self-produced LH (e.g. late antagonist protocols where drugs such as Ganirelix/Cetrotide/Orgalutron that are first administered 6-7 days after ovarian stimulation has commenced).

Hello Dr.Sher. I am 27 years old and I have had irregular periods since stopping birth control in May of 2015 in hopes of achieving pregnancy. Unfortunately not pregnant. Some months my period can last ranging from 3-4 weeks and some months I don’t have a period at all . Went to my obgyn and had a transvaginal ultrasound and everything came back normal and I had a blood test and the only abnormality was my testosterone level ( which was 59 I think ) . So she wants to me take clomid and provera to achieve pregnancy . I’m told to wait to take provera on January 1 , 2017 to jumpstart another period because I had a period already in November that lasted until about the first week in December. Today is December 14 and for two days now I have been bleeding. So my question is should I take the clomid without prover if I bleed for three days or should I wait because it’s almost like a had two periods in a month ? Also the dr said I may have PCOS because of my high level of testosterone (59) but she says its mild PCOS and I’m wondering how is that if I have no cyst and had a normal ultrasound ? Thank you in advance.
Yes, clomiphene is usually the 1st line of treatment with irregular ovulation and irregular bleeding, often associated with PCOS.
Polycystic ovary syndrome (PCOS) is a common hormonal system disorder among women affecting between 5% and 10% of women of reproductive age worldwide. Women with PCOS may have enlarged ovaries that contain small collections of fluid — called follicles — located in each ovary as seen during an ultrasound. The condition is characterized by abnormal ovarian function (irregular or absent periods, abnormal or absent ovulation and infertility), androgenicity (increased body hair or hirsutism, acne) and increased body weight –body mass index or BMI. The ovaries of women with PCOS characteristically contain multiple micro-cysts often arranged like a “string of pearls” immediately below the ovarian surface (capsule).interspersed by an overgrowth of ovarian connective tissue (stroma).
PCOS is one of the most common causes of menstrual irregularities, infertility, and hirsutism, Despite an enormous effort to define its cause, the etiology of PCOS remains unclear, and there is no definite cure at this time. PCOS is clearly a heterogeneous disorder which often has a familial (genetic) basis. Infertility associated with PCOS has been attributed to numerous factors, including dysfunctional gonadotropin pituitary secretion, peripheral insulin resistance, elevated adrenal and/or ovarian androgen (male hormone) levels, and dysfunction of several growth factors. Women with this condition are often obese and insulin resistant. The compensatory hyperinsulinemia further stimulates ovarian androgen production which may be detrimental to egg maturation and there is a clear link between the degree of insulin resistance and anovulation. PCOS is also a significant long-term health risk for women, thus necessitating vigilance through regular annual examinations (non-insulin dependent diabetes mellitus, hypertension, hypercholesterolemia, cardiovascular disease and endometrial cancer). Whereas PCOS-related infertility is usually manageable through the use of fertility drugs, lifestyle changes (diet and exercise) remain a mainstay of long-term therapy. More recently, ovulation rates, circulating androgens, pregnancy rates and perhaps even first-trimester miscarriage rates have been shown to improve when insulin sensitizers like metformin are used to correct the underlying insulin resistance.
Most patients with PCOS are young and have excellent pregnancy rates with oral clomiphene. Those that require more aggressive treatments with injectable medications probably represent a subgroup of PCOS patients with severe ovarian dysfunction. These women often have explosive response to gonadotropins which can result in serious complications like Severe Ovarian Hyperstimulation Syndrome (OHSS…see below) and high order multiple births. In those women, the ability to perform “prolonged coasting” (see below) and selectively transfer fewer embryos during IVF offers a clear advantage over standard gonadotropin injections.
Egg quality in PCOS
The potential for a woman’s eggs to undergo orderly maturation, successful fertilization and subsequent progression to “good quality embryos” is in large part genetically determined. However, the expression of such potential is profoundly susceptible to numerous influences, especially intra-ovarian hormonal changes during the pre-ovulatory phase of the cycle. Proper follicular stimulation as well as precise timing of egg maturation with LH (Luteinizing Hormone) or hCG (human chorionic gonadotropin) is crucial to optimal egg maturation, fertilization and ultimately embryo quality. Both pituitary gonadotropins, LH and FSH (follicle stimulating hormone) play a pivotal but different role in follicular development. The action of FSH is mainly directed toward granulosa cell (cells lining the inside of the follicle) proliferation and estrogen production (E2). LH, on the other hand, acts primarily on the ovarian stroma (the connective tissue that surrounds the follicle) to produce androgens. While small amounts of ovarian androgens, such as testosterone, enhance egg and follicle development, over-exposure to them can have a deleterious effect. Furthermore, excessive ovarian androgens can also compromise estrogen-induced endometrial growth and development.
Suppressing pituitary secretion of LH with gonadotropin releasing hormone (GnRH) agonists such as Lupron®, is particularly useful in PCOS. In that condition, serum LH levels are elevated, leading to stromal overgrowth, follicular arrests (so-called cysts) and high levels of androgens synthesis. It is therefore not surprising that these follicles often yield poorly developed (“immature”) eggs” at the time of egg retrieval (ET) and that “poor egg/embryo quality”, inadequate endometrial development and high miscarriage rates are common features of this condition. However, contrary to popular belief, this is not due to an intrinsic deficit in “egg quality”. Stimulation protocols geared toward optimizing follicle and egg development and avoiding over exposure to androgens correct these problems ad result in pregnancy rates similar to those of non-PCOS women. Whereas the overuse of LH-containing preparations such as Menopur® and Luveris® further aggravates this effect. In conclusion, to maximize ultimate oocyte maturation, we strongly recommend against the exclusive use of such products in PCOS patients, preferring FSH-dominant products such as Folistim®, Gonal F® or Bravelle® over a period of at least 9 days following pituitary suppression with Lupron®.
PCOS women often have a family history of diabetes and demonstrable insulin resistance (evidenced by high blood insulin levels and an abnormal 2-hour glucose tolerance test).This underlying Diabetes mellitus tendency could play a role in the development of PCOS and contribute to the development of obesity, an abnormal blood lipid profile, and a predisposition to coronary vascular disease. Women with PCOS are slightly more at risk of developing uterine, ovarian and possibly also breast cancer in later life and accordingly should be evaluated for these conditions on a more frequent basis than would ordinarily be recommended to non-PCOS women.
Most women with PCOS either do not ovulate at all or they ovulate irregularly. As a consequence thereof they in addition usually experience delayed, absent or irregular menstruation. In addition, an inordinate percentage of the eggs produced by PCOS women following ovulation induction, tend to be chromosomally abnormal (aneuploid). Rather than being due to an intrinsic egg defect being inherent in PCOS women, the poor egg quality more than likely the result of over-exposure to male hormones (predominantly, testosterone) produced by the ovarian stroma. These two factors (ovulation dysfunction and poor egg quality) are the main reasons for the poor reproductive performance (infertility and an increased miscarriage rate) in PCOS women.
PCOS patients are at an inordinate risk of severely over-responding fertility drugs, both oral varieties (e.g. Clomiphene, Serophene & Femara) and especially the injectables (e.g. Follistim, Puregon, Gonal F, Menopur and Bravelle) by forming large numbers ovarian follicles. This can lead to life endangering complications associated with sever ovarian hyperstimulation (OHSS). In addition PCOS women receiving fertility drugs often experience multiple ovulations putting them at severe risk (40%+) of high order multiple pregnancy (i.e. triplets or greater) with often devastating consequences.
VARIETIES OF POLYCYSTIC OVARIAN SYNDROME:
1) Hypothalamic-pituitary-PCOS: This is the commonest form of PCOS and is often genetically transmitted and is characteristically associated with a blood concentration of Luteinizing Hormone (LH) that is uncharacteristically much higher than the Follicle Stimulating Hormone (FSH) level (FSH is normally higher than the LH concentration) as well as high-normal or blood androgen ( male) hormone concentrations (e.g. androstenedione, testosterone and dehydroepiandrosterone -DHEA).Hypothalamic-pituitary-ovarian PCOS is also often associated with insulin resistance and in about 40%-50% of the cases.
2) Adrenal PCOS: Here the excess of male hormones are derived from overactive adrenal glands rather than from the ovaries. Blood levels of testosterone and/or androstenedione raised but here, but here, the blood level of dehydroepiandrosterone (DHEAS) is also raised, clinching the diagnosis.
3) Severe pelvic adhesive disease secondary to severe endometriosis, chronic pelvic inflammatory disease and/or extensive pelvic surgery: Women who have this type of PCOS tend to less likely to hyperstimulate in response to ovulation induction . Their. DHEAS is also is not raised.
TREATMENT OF INFERTILITY DUE TO ASSOCIATED OVULATION DYSFUNCTION:
Hypothalamic-pituitary-/ovarian PCOS: Ovulation induction with fertility drugs such as clomiphene citrate, Letrozole (Femara) or gonadotropins, with or without intrauterine insemination (IUI) is often highly successful in establishing pregnancies in PCOS women. However, IVF is fast becoming a treatment of choice (see below).
In about 40% of cases, 3-6 months of oral Metformin (Glucophage) treatment results in a significant reduction of insulin resistance, lowering of blood androgen levels, an improvement in ovulatory function, and/or some amelioration of androgenous symptoms and signs.
Surgical treatment by “ovarian drilling” of the many small ovarian cysts lying immediately below the envelopment (capsule) of the ovaries, is often used, but is less successful than alternative non-surgical treatment and is only temporarily effective. The older form of surgical treatment, using ovarian wedge resection is rarely used any longer as it can produce severe pelvic adhesion formation.
Adrenal PCOS is treated with steroids such as prednisone or dexamethasone which over a period of several weeks will suppress adrenal androgen production, allowing regular ovulation to take place spontaneously. This is often combined with clomiphene, Letrozole and/or gonadotropin therapy to initiate ovulation.
PCOS attributable to Pelvic Adhesive Disease is one variety which often is associated with compromised ovarian reserve, a raised FSH blood level and ovarian resistance to fertility drugs. In many such cases, high dosage of gonadotropins (FSH-dominant) with “estrogen priming” will often elicit an ovarian response necessary for successful ovulation induction and/or IVF. Neither steroids nor Metformin are helpful in the vast majority of such cases.
PCOS women undergoing ovulation induction usually release multiple eggs following the hCG trigger and are thus at inordinate risk of twin or higher order multiple pregnancies. They are also at risk of developing OHSS. Many now believe that IVF should be regarded as a primary and preferential treatment for PCOS. The reason is that it is only through this approach that the number of embryos reaching the uterus can be controlled and in this manner the risk of high-order multiples can be minimized and it is only in the course of IVF treatment that a novel treatment method known as “prolonged coasting” ( see below) which prevents OHSS, can be implemented
SEVERE OVARIAN HYPERSTIMULATION SYNDROME (OHSS):
As indicated above, there is an inordinate propensity for women with PCOS to hyper-respond to gonadotropin fertility drugs and in the process produce large numbers of ovarian follicles. If left unchecked this can lead to OHSS, a potentially life endangering condition. The onset of OHSS is signaled by the development of a large number of ovarian follicles (usually more than 25 in number). This is accompanied by rapidly rising plasma estradiol (E2) levels, often exceeding 3000pg/ml within 7 or 9 days of stimulation, often rapidly peaking above 6,000 pg/ml prior to hCG administration. When this happens, the risk of OHSS developing is above 80%.
Symptoms and signs of OHSS include: abdominal distention due to fluid collection (ascites), fluid in the chest cavity (hydrothorax), rapid weight gain (of a pound or more per day) due to tissue fluid retention, abdominal pain, lower back ache, nausea, diarrhea, vomiting, visual disturbances such as blurred vision and spots in front of the eyes (scotomata), a rapidly declining urine output, cardiovascular collapse and failure of blood to clot which sometimes results in severe bruising (echymosis) and frank bleeding. These symptoms and signs may appear before pregnancy can be diagnosed. If pregnancy occurs, the condition is likely to worsen progressively over a period of 3-5 weeks whereupon it rapidly resolves spontaneously over a few days. If no pregnancy occurs, the symptoms and signs all disappear spontaneously within 10-12 days of the hCG injection.
When increasing fluid collection in the abdominal cavity (ascites) starts to compromise breathing raising the head of the bed rose slightly by placing a 4-6 inch block at the base of each head post and using a few additional pillows, will sometimes help ameliorate the problem. In cases where this does not help or symptoms become severe, all or most of the fluid can readily and safely be drained through t transvaginal sterile needle aspiration (vaginal paracentesis-performed once or sometimes twice a week) can be performed once or twice weekly . The problem will usually self corrects within 10-12 days of the hCG shot if pregnancy does not occur or, by the 8th week of pregnancy.
Urine output should be monitored daily to see if it drops below about 500ml a day (about two cups and a half). A chest X-ray, to evaluate for fluid collection in the chest and around the heart should be done weekly along with blood tests for hematocrit, BUN, electrolytes, creatinine, platelet count and fibrin split products (FSP). If indicated on the basis of a deteriorating clinical situation, hospitalization might be needed for close observation and if necessary, to provide intensive care.
In all case of OHSS, the ovaries will invariably be considerably enlarged. This is irrelevant to the final outcome, unless ovarian torsion (twisting of the ovary on its axis), an extremely rare complication occurs. The latter would usually require surgical emergency surgical intervention.
It is important to know that symptoms and signs of OHSS are severely aggravated by rising hCG levels. Thus such patients should not receive additional hCG injections.
Does PCOS cause poor egg/embryo quality? It is an undeniable fact that women with PCOS undergoing IVF are commonly found to have poorly developed (“dysmorphic”) eggs, with reduced fertilization potential and yielding “poor quality embryos”. However, in the author’s opinion (which admittedly runs contrary to popular opinion), this is unlikely to be due to an intrinsic deficit in egg quality. Rather, it more likely relates to intra-ovarian hormonal changes brought about by hyperstimulation and which compromise egg development. This effect, in the author’s opinion, can often be significantly reduced through implementation of an individualized or customized ovarian stimulation protocols that minimize exposure of the developing follicles and eggs to excessive LH-induced ovarian androgens. This can be best achieved by limiting the use of LH-containing gonadotropins such as Menopur through selective institution of “prolonged coasting” (see below).
In the past, the onset of OHSS, heralded by the presence of large numbers of developing ovarian follicles and rapidly rising plasma estradiol levels often led the treating physician to prematurely administer hCG in an attempt to abruptly arrest the process and prevent escalation of risk to the patient. However the premature administration of hCG, while abruptly arresting further proliferation of estrogen producing granulosa cells in the follicles, unfortunately also prematurely arrests egg development. Since the ability of an egg to achieve optimal maturation upon hCG triggering is largely predicated upon it having achieved prior optimal development, the untimely administration of hCG which triggers meiosis, probably increases the risk of numerical chromosomal abnormalities (aneuploidy) of the egg. This in turn would lead to reduced fertilization potential, poor egg/embryo quality and low embryo implantation potential.
In women with PCOS the connective tissue that surrounding the follicles (ovarian stroma) is often characteristically overgrown (stromal hyperplasia). It is the stroma that produces androgens (mainly testosterone) in response to LH. It is this, coupled with the fact that PCOS women also often have elevated blood LH concentrations (see above) results in the excessive production of androgen hormones, which is so characteristic in PCOS. While excessive exposure of developing eggs to ovarian androgens compromises follicle and egg growth it also impairs endometrial response to estrogen, which could explain the common finding of poor endometrial thickening in many PCOS women undergoing IVF.

The obvious remedy for these adverse effects on egg and endometrial development is to employ stimulation protocols that limit ovarian over-exposure to LH and allowing the time necessary for the follicles/eggs to develop optimally, prior to administering hCG through the judicious implementation of “Prolonged coasting” (PC).
Clomiphene (syn; Clomid , Serophene) is by far the most widely prescribed agent for the induction of human ovulation for women who do not ovulate, those with dysfunctional ovulation and women with ”unexplained” infertility. When used in young women (who have adequate ovarian reserve) with these problems the viable pregnancy rate is reported as being between 6% and 10% per cycle of treatment. Aside from conventional ovulation induction, clomiphene has been used in preparing women for intrauterine insemination and even for IVF. I personally rarely prescribe clomiphene because across the board, success rates are significantly lower than when gonadotropin therapy is used. The main reasons for clomiphene’s popularity is its low cost, simplicity of use and the low risk of dangerous complications such as severe ovarian hyperstimulation syndrome (OHSS).
Clomiphene treatment can be initiated at a dose of 50 mg (orally) daily for 5 days but it can be increased to as much as 200mg per day, starting on cycle 2, 3, 4, or 5. A spontaneous LH surge will usually follow within about 8-9 days of the last 50mg dosage. In some cases, 10,000U of hCG can be given as a trigger when there is at least one ovarian follicle of 18-20 mm in size. Routinely using the hCG trigger does tend to decrease pregnancy potential.
Clomiphene works by inducing ovulation through its “antiestrogen effect” which, by blocking estrogen receptors in an area of the brain known as the hypothalamus, tricks the brain into “thinking” that estrogen levels are low. In response, the hypothalamus prompts the pituitary gland to release an exaggerated amount of follicle-stimulating hormone (FSH), which in turn stimulates the growth and development of ovarian follicles, ultimately resulting in a surge in the release of pituitary LH. About 38-42 hours later, ovulation occurs from one or more of the larger follicles. As the follicles grow, they release more and more estrogen into the bloodstream, thus closing the feedback circle that the hypothalamus initiated in response to the anti-estrogen properties of Clomiphene.
There are several factors that need to be considered carefully before deciding to prescribe clomiphene to any woman:
•Clomiphene citrate therapy is less effective than gonadotropin therapy and its efficacy declines with advancing age: Many infertile couples undergoing ovulation induction believe that the success rate using clomiphene citrate is equivalent to what we see in fertile couples trying to get pregnant on their own and to what is encountered when gonadotropins (Menopur/Follistim/Gonal-F and Puregon) are used. This is not the case. The truth is that the rate of conception with clomiphene therapy is actually about 30% lower than the natural fertility rate for normally ovulating women, and about 25% lower than when gonadotropin stimulation is used for ovarian stimulation in similar patients. Moreover, the discrepancy is further magnified with advancing maternal age, where in women under 35 years, the pregnancy rate with clomiphene treatment is about 10% per cycle, about 5% between 35 and 40 years and <2% for women in their early to mid-forties.
•Clomiphene use should ideally be confined to younger women: Ideally the use of clomiphene should in my opinion be restricted to younger women (under 35 years) who have normal “ovarian reserve” (as assessed by basal blood FSH, and antimullerian hormone (AMH) levels). These are the women who are most likely to respond by producing multiple follicles. It is necessary that at least 3 sizeable follicles (>15mm) develop on clomiphene treatment, in order to override the “anti-estrogenic” effects of this drug and so insure adequate cervical mucus production as well as the development of a receptive endometrium.
•Clomiphene should usually not be administered for more than 3 consecutive (back-to- back) cycles: If used back-to-back for more than 3 consecutive cycles, clomiphene is not only ineffective, but actually starts to function as a “relative” contraceptive! This is often is a shocking revelation to many women. Clomiphene’s anti-estrogenic effect is not confined to the hypothalamus. Any cells that have a high concentration of estrogen receptors will also be so affected. Needless to say, the cervical glands (that produce estrogenic mucus to facilitate sperm transport and the endometrial lining (endometrium) that thickens under the effect of estrogen are also highly vulnerable to a buildup of antiestrogen effects over successive back-to back cycles of clomiphene therapy. This why with >3 consecutive back-to back clomiphene cycles cervical mucus tends to thicken and dry up and the endometrium will thin, seriously reducing the likelihood of success. These anti-estrogenic manifestations require that following 3 back-to back clomiphene cycles of stimulation there be at least 1 resting (non-clomiphene treated) cycle, before doing a 4th cycle.
•Clomiphene should not be used in older women or in women who have diminished ovarian reserve (DOR): With clomiphene stimulation, the release of pituitary FSH is always accompanied by the concomitant release of Luteinizing Hormone (LH). LH causes the ovary to produce male hormone (androgens) and testosterone. The production by the ovaries of a modest amount of testosterone would not present a problem. However, an excessive production of ovarian testosterone prejudices egg development and thus ultimately compromises embryo competency. Older women and women with DOR are the most vulnerable because they tend to have overgrowth of ovarian connective tissue (stroma/theca) which is the site where androgens are produced. The concentration of androgens is always much higher at the site of production (the ovaries) than in the peripheral blood (a dilution effect). Thus in older women and those with DOR, there will be excessive ovarian androgens that can compromise egg quality and thus ultimately reduce the chance of having a baby. The older the woman and/or the more severe the DOR, the greater this adverse effect is likely to be.
•“Trapped” ovulation (LUF-Syndrome): About 20% of clomiphene cycles are associated with “trapped” ovulation (Luteinized Unruptured Follicle (LUF) Syndrome). This means that in spite of hormone changes suggesting that ovulation has occurred, the egg remains trapped in the ovary. Obviously this is not condusive to the establishment of a successful pregnancy.
•Endometriosis is a “relative contraindication” to the use of clomiphene: Women with endometriosis (regardless of its severity) have” toxic factors” in their pelvic peritoneal fluid. Eggs, as they pass from the ovaries to the Fallopian tubes to reach the awaiting sperm, become exposed to these “toxins” which renders the egg envelopment (zona pellucida) resistant to sperm penetration. This reduces fertilization potential by a factor of at least 3 or 4. This means that if, in the absence of endometriosis, an egg has a 15% chance of being fertilized and thereupon resulting in a baby, that same egg, in a woman with endometriosis would have no more than a 5% chance. Thus, if the overall chance of a having a baby per year of actively trying is about 12% then the chance in a woman with mild endometriosis (of the same age) would probably be no more than 3-4%. This serves to explain why normally ovulating women with endometriosis and patent Fallopian tubes do not benefit significantly from intrauterine insemination, with or without the use of fertility drugs, or from surgery to remove endometriotic lesions (since many endometriotic deposits are non-pigmented, thus invisible to the naked eye and cannot be removed surgically). Only IVF improves the chance of a baby per month of trying. Simply put…if a normally ovulating woman who has mild to moderate endometriosis conceives following IUI, surgery, or the use of fertility drugs, it is probably in spite of (rather than due) to such treatment.
•Women with long gaps between menstruation are often not ideal candidates for clomiphene: Women who consistently have >45 days between their periods will not respond well to clomiphene induction of ovulation and are better off going directly to injectable gonadotropins.
•Multiple pregnancy: The incidence of multiple pregnancies with clomiphene induction of ovulation is about 5%. This is much lower than the 25% rate encountered when gonadotropins are given to women with absent or dysfunctional ovulation.
Clomiphene therapy is often used as a first line approach to inducing ovulation in women with irregular or absent ovulation such as in women with polycystic ovarian syndrome (PCOS). Its use in my opinion is best confined to women who menstruate/ovulate irregularly (but who bleed at least every 45 days), younger women, women who do not have tubal disease or endometriosis, women under 40 years of age (preferably <35Y), and women who do not have DOR . It should also be avoided when there is co-existing male factor infertility. If pregnancy fails to occur after 3 consecutive cycles of clomiphene therapy, then in my opinion, it is time to move on to gonadotropin therapy, combined with IUI or IVF/ICSI depending on the underlying cause of the infertility.
Good luck and Merry Xmas.
