Wondering About Follicle Size And Ovidrel Shot

Question:

Hi, I am on Gonal-f and my US (ultra-sound) yesterday showed I had 2 follicles measuring at 17mm and 14mm, my doctor told me to take one more shot of 75ui Gonal-f last night and to trigger with ovidrel tonight.

Do you think my eggs will be mature enough to ovulate???
Thanks! N. from the U.S.

Answer:

Hello N. from the U.S.,

If the follicles grow normally, they should increase by 2 mms each day. That means that they will be 19 and 16 mms the next day. I NEVER trigger without knowing the follicle size for sure. That is sloppy care. In addition, I would want you to be able to ovulate both follicles so I would probably wait one extra day and use the gonal-f another day. That way the follicle sizes should be 21 and 18 mms, so that both would be ovulatory size. Since follicles don't always follow the expected growth rate, I feel you have to look each day to know for sure.

In terms of your question, if the follicles grow to 19 mms and 16 mms the next day, then the 19 mm follicle definitely should ovulate and the 16 mm follicle may or may not.

After Failing IVF Three Times 45 Yr Old Wonders, Higher Stim or Lower Stim? Use BCP?: I Recommend A High Stim Mixed Protocol & BCP

Question:

Hi Dr. Ramirez,

I am 44 turning 45 this June. I have had 3 failed IVFs - 1 didn't go beyond retrieval because I pre-ovulated so no eggs to retrieve. My recent failed ivf cycle I had 3 follicles 19mm, 18mm and 16.5mm. The biggest follicle had no egg, the second largest had a degenerative cell and the third an immature egg. I took 300 iu's of follistim and 1 vial of menopur increased to two mid cycle.

Can taking too little or too much meds (follistim/menopur) cause this outcome?

We are trying a gentler dose and using follistim instead of gonal f. My first few cycles I was taking 600 iu's of gonal f and 150 iu;s of menopur. They had me doing this protocol for months and I started to respond poorly to it. I insisted on changing the meds or trying a gentler dose.

We interviewed with a new doctor here and his approach is less is more, less meds and get better quality vs. quantity eggs. And is it true that the smaller follicles esp. women my age will have bad eggs? My last cycle debunked that whole theory because the dominant follicle or the two largest didn't have any eggs. The smallest follicle did have an egg but it was immature.

I know that on the average I produce 5-8 follicles per cycle. I think it's important to save as many of the follicles we can, we can't afford not to even if they have bad eggs in them. I am not young and producing 20 follicles. How much do you recommend women my age take in meds (follistim/menopur)? The new doctor wanted to put me on 150iu's of follistim every other day or maybe everyday? That did not seem enough? He only wants to stimulate the dominant follicle or larger follicles. I don't want to take so little that it doesn't stimulate enough or take too much that I can get overstimulated and not respond well. I know my body and I am very sensitive to the drugs. I have also used micro-dose lupron and I responded poorly to it.

What protocol do you at your clinic use on women my age? My recent baseline fsh is 8.6, E2 is 30 and my AMH 0.27. It started low and increased up to 0.7 taking dhea and in the last few months started to decrease. I have no other issues other than my age and thyroid disease but it's under control. Do you change dosage depending on blood levels, number and size of follicles? The doctors I went to never did that.

Do you use clomid or birth control pills? I am not fond of either of them but I have heard and read that if you are on clomid you third ivf cycle will be successful? I prefer to use estrace or patches over the birth control pill to suppress. Why do clinics use birth control pills? I have read clomid was found to give cancer to lab rats?

Your help is greatly appreciated. I don't have time to waste anymore.

Thank you, C. from New York

Answer:

Hello C. from New York,

In general I don't comment on specific protocols because each doctor has their personal preferences and there are none that are perfect or better than others. However, I don't think I like your new doctor's recommendations or protocols and I'll explain why.

The biggest hurdle that you are facing is an age related decline in egg quality AND a decreased ovarian reserve. There is nothing that can be done about the egg quality but the goal with IVF is to increase the number of eggs recruited and available in the hope that a good egg is still present and we can find it. So, the protocol is always to try to stimulate an increased number of follicles and hopefully eggs.

I have read studies where the argument is if you use a natural cycle (no stimulation or decreased stim cycle), the egg quality will be better, but I believe that to be nonsense. Why would decreasing the number of follicles or relying on a natural cycle (only one follicle) produce better eggs? That is illogical. The quality of the eggs are already predetermined. Stimulation or lack thereof does not influence its quality. Again, I believe that the only way to overcome the age factor is to try to get the maximum number of eggs out at a time. For this I use a high protocol or mixed protocol that is 450IU of follistim and 150IU of Menopur. I also Do Not Use Lupron (called the long protocol) because I think it is inhibiting the ovaries too much at the time of follicle recruitment. Instead I use an antagonist protocol where the antagonist is given for only 1-3 days.

The only time I will decrease the amount of medication is if the patient has gone through one or two IVF cycles and still the number of follicles encountered or eggs retrieved are few. I decrease the protocol because I don't want her to spend lots of money on medications if the increased amount is really not doing too much. The ovaries do get to a point where they won't stimulate much despite increased dosage of medications. Unfortunately, your ovaries sound like they are there already. Again, the reason for doing this is to reduce the cost of medications.

I do alter my dosages as the cycle goes on, but only if I am starting from a lower dose and the patient is not stimulating, in which case I increase the dosage, or if I start on a higher dosage protocol and she is stimulating too strongly, in which case I decrease the dosage. Other than that, the dosage stays the same for most of the cycle without alterations.

I would not even consider Clomid for an IVF cycle. Some clinics do again to decrease the cost of medications but multiple studies show that the injectables are superior to Clomid.

Finally, in terms of the birth control pill, I do use it. Several studies have shown a better response if preceded by birth control pills. It suppresses the ovaries in the cycle preceding the IVF cycle and there may be a rebound effect so that the ovaries stimulate better. Estrogen does not suppress the ovaries unless given in very high amounts such as with the birth control pill. I have read of clinics trying to do IVF after a natural "unsuppressed" cycle, but I don't think it makes much difference. The other reason to use the birth control pill is that it allows us to take control of your cycle so that we can be sure that timing is correct. Timing is absolutely critical with IVF. There is a very small window of opportunity for the embryo to implant and if you miss it, then the cycle will fail. Also, using the birth control pill helps with scheduling if you batch patients (put them in the same group).

I think it is meritorious that you are trying to achieve pregnancy with your own eggs at 45 years old, but you have to understand that pregnancies rarely occur after 43 even with IVF unless donor eggs are used. However, I always remind my patient that the oldest woman to achieve pregnancy through IVF using her own eggs was 49 years old. It did take her two years of doing IVF, so persistence can count if you can afford it and want to wait that long to have a child. But you also have to be realistic and not let your expectations be too high. I hope that your journey will go well nonetheless, and that you achieve your goal of having a child.

Possible PCO Patient Adjusting IVF Antagonist Protocol For Fear Of OHSS: Decrease Gonal-F Dosage?

Question:

I am about to start my first IVF protocol (today is CD2). I am concerned about the recombinant FSH dosage prescribed and would like your opinion regarding appropriate dosage. I believe I am at higher risk for OHSS for several reasons (described below), however my recent ultrasounds are not showing definitive signs of PCO. Here is the protocol prescribed by my doc:

No pre-cycle BCPs (they make me very ill)
CD2: gonal-f 225
CD3: gonal-f 225
CD4: gonal-f 150
CD5: gonal-f 150
ultrasound on day 6
addition dosing determined following this ultrasound
Gonarilex to prevent premature ovulation

I called the doctor today because I was nervous about taking the first two days of 225IU gonal because of the risk of OHSS. After very little discussion, he switched me to 150IU for 4 days.

The difference between 225 and 150 is a big change. I wonder if I will get good results with a dosage that is this low. What is your opinion? I feel like there might be some sort of middle ground that is more appropriate? I would appreciate any thoughts. I would like to get the "best" results without complications of OHSS.

I believe I am at higher risk for OHSS than the normal woman for many reasons:

1) my ultrasound yesterday (on CD1) shows 9 follicles on right and 16 on left

2) I responded well to low doses of gonadotropins (6 IUI cycles some with letrozol/femera at 5mg/day?, others with clomid at 25mg/day all cycles gave 3-5 mature follicles on CD12),

3)I am petite (5'2", 100 lb.s)

4) in 2006 a doctor told me I had PCOS based on ultrasound results, a history of severe PMS, and moderate acne(two additional doctors I consulted with gave no diagnosis - I am not hairy or pear-shaped)

5) cancelled IUI due to elevated estrogen associated with a small complex cyst on cd2 (and another very uncomfotable IUI cycle when a different OBGYN proceeded with an IUI when I had a cyst at the start of my cycle).

6) grandma had type 2 diabetes

7)early male baldness runs in my family.

Answer:

Hello J. from the U.S.,

First of all, I have to caution you about trying to second guess your doctor. Sometimes that may not be good. I would presume that your doctor had a logical reason for selecting your protocol.

You were originally scheduled to be on a 3 down protocol (75IU x 3 for two days then decrease). That is a standard protocol and is on the low side. Because of your concern, your doc decreased you to 150IU and will make adjustments based on the response. The only down side to the lower protocol is that you may not recruit as many follicles as the higher dose, but there is no way to know this when it is the very first cycle. In most cases we determine the protocol based on an educated guess. The adjustment at CD#6 is still early enough to increase the dosage and recruit more follicles if necessary, and if you are indeed a PCO, then you will already have an increased number of follicles and the decreased dosage will be safer for you.

I am glad to see that your doc is using the "antagonist" protocol with ganerelix. I am a firm believer in this medication and its ability to decrease the risks of OHSS. With the antagonist, instead of using HCG to trigger ovulation, Lupron can be used to trigger and because of its shorter half-life, the risk of OHSS is dramatically reduced. This is the protocol I use with my PCOD patients to reduce their risk, in addition to careful monitoring, lowered FSH dosage, Drifting (if necessary) and Coasting (if necessary). My goal is to keep the Estradiol level less than 4000 at the time of trigger. With this protocol, I have had no incidence of OHSS in my center for the past 5 years. Most the reasons that you gave for being PCOD are not valid criteria, but my concern would be the same as yours based on the high number of antral follicles seen on ultrasound. I treat patients as a PCO patient if they have PCO-appearing ovaries even if they don't meet the strict criteria for PCO. And, I find that they do stimulate like a PCO ie have a high number of follicles (>25).

In your case, I think that being safe is better than being sorry and the lower dose is probably the way to go. I call your new protocol a 2up protocol and it is a standard protocol that I use with my PCO patients. I check estradiols at CD#5, however, and adjust from there.

45 Year Old Danish Couple On Sixth IVF Attempt: Should They Alter Meds & Blastocyst Transfer?

Question:

Dear Dr. Ramirez,

We are a 45 year old couple from Denmark on our sixth IVF attempt. The first three attempts produced 5/5/9 eggs with 225-275 units of Gonal-F and a fertility rate of 100%/60%/60% respectively. Eggs for transfer were three 8-cells on try one on day three, two 8-cells and one 10-cell on try two on day three and two morulas and a 10-cell on the third attempt on day five.

We then increased Gonal-F to 375 units and got 12 and 13 eggs in the next two attempts and a fertility level of 85%-100% and decided to go for Blastocysts and had two BC's and a Morula in the fourth attempt on day six and one BC and a Morula transferred the last time on day six. On the recent attempts we've been supplementing with Ovitrelle prior to aspiration (as well as folic acid, acupuncture and considerate food and no alcohol of course). After aspiration a dose of 16mg Medrol was administered for four days, then 8mg and then 4mg, as well as 81mg of Aspirin for the duration.

Our questions are: 1)should we continue to go for Blastocysts for transfer, and 2) do you have any suggestions as to an altered protocol perhaps in terms of increasing the dose or frequency of Medrol or any other meds that might help us?

Thanks in advance for your reply. T. From Denmark

Answer:

Hello T. from Denmark,

The good news is that your wife's ovarian response is still good and strong. She has done very well on her current stimulation protocols. The problem that you have is not so much the external quality of the embryos formed, they have been good, but the internal quality of the embryos. We know that with age, the quality of the eggs and thus the embryo quality deteriorates. That is probably what is leading to your failure. We rarely see pregnancies after the age of 43 in a woman using her own eggs. However, there was a case in New York of a woman who was successful at 49 years old, and is currently the oldest to become pregnant with her own eggs using IVF. It did take her two and 1/2 years of trying, however. Statistically, your chances of pregnancy with IVF are less than 1% per attempt based on age factors alone.

In terms of whether to do D#3 or D#5 transfers, I don't think it makes any difference. One is not better than the other. The embryos that would make it to blastocyst would still have done so in the uterus. In fact, I think the uterus is a better culture environment than the lab. I generally transfer at D#3 for this reason. In fact, in your case if you were my patient, I would transfer ALL embryos back on D#3 to maximize your chances.

In terms of what other protocols, I use Medrol starting at the beginning of the cycle (D#2) taken as 16 mg until the transfer then decreasing to 8 mg thereafter. I stop with the pregnancy test. I also use aspirin 81 mg per day starting at the beginning of the cycle and heparin 2000 units twice per day injections starting at the beginning of the cycle. I also use a "mixed" protocol of Gonal-f or Follistim + Menopur/Repronex for a total FSH dose of 600IU to start. In most cases, the patients stay at that level but some will decrease based on their response. In your case, your wife does not need more meds since she stimulated well, but a mixed protocol might be advised.

Your only option is to keep trying or move to donor. I am amazed that you have done so many cycles already. Most in the U.S. will not do that many cycles due to cost issues.

Good luck with this upcoming cycle & never lose sight of your goal...it can be achieved if you are open to options.

Follow Up Question From 30 Yr Old Austrian Who Failed 5 IVF Cycles & Is Trying Once Again

This is a follow-up question from a young woman with possible PCOS in Austria, who first wrote me in March. Please view the first two questions she posed in order to fully understand the problems she and her husband face. See the March 18th blog post: http://bit.ly/cqXqAp

QUESTION:

Dear Dr. Ramirez,

I had asked you a couple of questions two months ago, and thought of you now as we are preparing to do another IVF. I copy below what you suggested in terms of protocol for me (PCO-like stimulator), since I discussed it with my doctor and he is not sure that this kind of protocol can be done with the medicines available in Austria. You said:"Patients start at a low dose of Follistim 150IU for three days then the estradiol level is checked for response. If there is not a high response then I step up the dosage to Follistim 150IU + Menopur 75. We continue the same pattern of checking and adjusting the dosage as needed. I don't use Lupron agonist suppression (long protocol), but instead use the Antagonist Ganerelix. When the follicles are appropriate sized, I trigger with Lupron 0.5 mg instead of Ovidrel. These combination and protocol has been shown to be effective in preventing hyperstimulation syndrome"

The protocol he gave me last time (Dec. 2009) (starting on day 3 of cycle) was:Day 3-5 Gonal-f (150IU)Day 6 Gonal-f (112 IU)Day 7 Gonal-f (112 IU) + Cetrotide (one shot 0,25 mg)Day 8 Cetrotide (0,25mg) + Pergoveris shotDay 9 Cetrotide (0,25 mg) + Pergoveris shotDay 10 Cetrotide (0,25 mg) + Pergoveris shotDay 11 Cetrotide (0,25 mg) + Pergoveris shot Triggering with OvitrelleEven though this protocol was substantially reduced in quantity of medication, I still had 15 eggs and mild-hyperstimulation (enough for being 3-4 days uncomfortable to breathe and in pain and swollen all around).

The doctor is now proposing a similar protocol to this, but reducing from 150 IU to 112 IU to start and see what happens. I showed him your suggestion and he was receptive but I don't know if the medicines you suggested can't be found here or if what he is suggesting is similar to what you suggested. We are thinking of not having a treatment here anymore and moving onto a treatment in the States. In an ultrasound on day 19 of my cycle, he saw that I had ovulated recently and noted that I have/had around 15 follicles (or left overs of follicles) in my two ovaries. I was really shocked since I have been medication free for 6 months, so I didn't expect that's normal to have so many follicles on a natural cycle, he said that could mean I have a high ovarian reserve and could be a sign of why I hyperstimulate every time no matter what medicine they have given me.

My questions:

Is the protocol he proposes similar to what you wrote above?

What do you think about this empty follicles in my ovaries now?

Also, he has me taking Thyrex for my thyroid (one pill of 50 mg per day) since I started treatment with him over 10 months ago because my TSH level was over 4, and he wants to keep it at around 1, but am I supposed to take this pill forever? for Hypothyroidism? That's what he said, that until I achieve a pregnancy and give birth, I should be taking that pill.

Another question: What do you think about that? My TSH has been at around 1 since i started taking the pill. Regarding my husband's sperm (CF gene), they have been using his frozen samples for all treatments, saying that the freezing and thawing act as natural selection, whatever survives is better for ICSI than trying with fresh sperm. Do you think is better to use fresh sperm for ICSI? or frozen?

Finally, we are thinking of going to a US clinic because in Austria PGD is prohibited, and for us they have been doing polar biopsy of my eggs to only transfer the embryos which fertilized with the better eggs, but as you noted in your previous emails, the embryos should be checked as well to eliminate any effect by my husband's sperm...correct?

So thank you so much for your answers, we are about to cancel the cycle here which starts in one week and move on to make an appointment in the States with you or another clinic which can take us.

Receive my warm regards, L. from Austria

Answer:

Hello Again,

I am happy, yet surprised to hear that your doctor was receptive to my suggestions. I do not dispense recommendations with the expectation that patients will share it with their Physicians. It is mainly for patient knowledge. I do not mean to intrude on that doctor-patient relationship, nor your doctor's judgement, since they usually know you better, and many doctors will be offended.

The medications Gonal-f and Follistim are the same, but made by different companies. Cetrotide is the same as Ganerelix. Gonal-f and Cetrotide are made by Serono, whereas, Follistim and Ganerelix are made by Organon. They are interchangeable. Based on the protocol you showed me, you were already on a pretty low dose protocol. Since, despite this, you hyperstimulated, I would reduce the dose further to a starting dose of 75IU or 37IU Gonal-f. I would probably fight the inclination to increase the dose above this because you seem pretty sensitive and 75IU may be all that you need to get an adequate number of mature eggs.

The Pergoveris is the same as Menopur (FSH/LH). If it is added, as your doctor did previously, he might want to reduce the dose to 37.5 IU (half-dose), but it isn't absolutely necessary. Some studies have shown decreased hyperstimulation in PCO patients when the FSH/LH is left off because PCO patients tend to have an elevation in LH production.

Once your lead follicles reach 15 mms (at least 20% of the follicles), Cetrotide should be started at 0.25 mg per day and continued until the trigger shot. The Gonal-f may need to be increased because of this ovarian suppression, and you should expect a decrease/drop in the estradiol level initially because some of the smaller follicles will stop developing due to the suppression and stop producing estradiol. That is okay and the cycle should be continued (this is contradictory to current thought, where if the estradiol drops the cycle is usually cancelled).

The trigger should NOT be HCG or Ovidrel. Instead, Lupron 0.5mg (50 mcg) should be used subcutaneously as the trigger. This has been shown, in European studies, to be just as effective as HCG but because of a shorter 1/2 life (the amount of time the drug is in your system), there is a decreased incidence of hyperstimulation.

In addition, to the above, I will also sometimes use "drifting/coasting" if it looks like the estradiol level will go above 4000 before the lead follicles are at a mature size. This requires that the doctor predict the levels on a daily basis and the drift/coast is not started until the lead follicles are at least 16 mms. You doctor should understand what this technique is. But, just in case he is not familiar with it, it is where the stimulationn with Gonal-f and/or FSH/LH is stopped but the ultrasound surveillance continues until the lead follicles reach 18-24 mms, then the trigger is given.

Finally, your doctor is correct that the TSH (thyroid hormone) levels have to be in the normal range, otherwise this can have an adverse effect on your pregnancy chances. As I said previously, PGD is the only way to rule out your husband's CF gene from the embryo, as egg polar body biopsy only evaluates the egg (your genes), and frozen sperm is just as good as fresh sperm. I am flattered that you would consider us for a second opinion, thank you. If you do decide to come to the U.S. I would certainly enjoy meeting you and your husband and be assured that our center would do anything that it can to accommodate you and help you succeed.

In closing, tell you doctor that I have had patients where I even start the Gonal-f/Follistim at 37.5IU and step up to 75 or 150IU, so he might want to consider that in you since you are so sensitive.

The very best of luck,

30 Yr Old Has Failed Three IUI's With Donor Sperm: What's Wrong?

Question:

Hello Dr. Ramirez,

I am a 30 y.o who is TTC with donor sperm. I have not been diagnosed with any infertility issues at this time. My HSG test was normal. I did the first IUI with clomid, the second and third IUIs with 150 units Gonal and 5 units Lupron for 12 days each producing 6 follicles. Each follicle was greater than 15mm. I triggered with ovidel the night before insemination. My estradiol two days prior to the IUI were 2500 and 1500 respectively.

I am curious if there is something medically that could be done differently to increase the odds of conceiving. Also is it possible that I am not genetically compatible with the donor sperm? I am frustrated with not having any answers.

Please help. K. from Upstate NY

Answer:

Hello K. from New York,

I don't think that "genetic incompatibility" is an issue. It does not exist. I am very, very worried about your gonal-f stimulation cycles, however. The estradiol levels of 2500 and 1500 are IVF levels, and that is where we are stimulating very strongly to get a maximum number of eggs. For an IUI cycle that is way too much stimulation. The goal with IUI is to have 3 ovulatory sized follicles (>16 mms) at the time of trigger and the minimum size needs to be 18 mms for ovulation to occur. Also, if you are only having one IUI done, it should be timed to be 33-36 hours from trigger. I prefer the two IUI technique at 24 and 48 hrs, which gets the fresh sperm into the tubes closer to ovulation.

Keep in mind that IUI is a natural process and just replacing trying with intercourse. Because of this, it has a maximum pregnancy rate of 24% per cycle, and can take up to 4 cycles to achieve pregnancy. In this case, you just need to keep trying. However, I am a little worried about the protocol that you are using. Are you seeing a fertility specialist for this? With IUI, we generally do not use Lupron suppression, but that is okay to use. It's just an extra drug and shot that you don't generally need.

I would not have given up on Clomid so quickly. It works well and is much, much less expensive than Gonal-f. The only reason I would go to Gonal or Follistim is if you did not respond to max dose Clomid (250 mg).

I hope this answers your questions. Good Luck,

Lupron trigger instead of HCG

Question:
My RE gave me a lupron trigger instead of my usual HCG or ovidrel trigger. It concerns me because when I read about lupron it is a ovulation suppressor. Did I ovulate? I took two lupron shots 12 hrs a part. I am now on progesterone supp. and patch along with a estrogen pill 3 x daily.
　
I was on 150 gonal-f for 9 days and then 75 for day 10. I also used ganarelix starting day 5 of stim. My E2 was higher than my RE liked and he wsa worried about OHSS. It was an IUI cycle. I OHSS in 2004 when I got preg. with my twins.
　　
I love my RE, but I just can not find much info on lupron trigger so I am a little concerned.

Answer:
Hello Michelle from the U.S.,
　　
The Lupron trigger has been used extensively and written about extensively in Europe. It is better than HCG with hyperstimulation because it has a shorter duration, reducing the chances of developing OHSS. I use it with my PCO patients who have a tendency to hyperstimulate and are at higher risk of OHSS. As a result, I have not had a patient with OHSS in years. I only given one injection, not two. Lupron used daily or in the higher doses can certainly suppress the ovary. It works indirectly but has the same effect as the Ganerelix. In low doses, it mimics HCG and triggers ovulation. I love the Ganerelix-Lupron protocol.
　
My biggest concern with your story is why you are following an IVF protocol for an IUI cycle? You are getting stimulated way too much. With IUI, we only want up to 3 ovulatory sized follicles. If you ovulate more than that, you will be at high risk of a super-multiple pregnancy (not good). Also, if you stimulated so much that your RE would be worried about hyperstimulation then you should not be completing the cycle. It should be cancelled, again because of the high risk of a super-multiple. OHSS occurs when the Estradiol level is greater than 4000 and you have more than 20 follicles. that's way too much for an IUI cycle!!!　
　
I think you have good reason to be concerned.
　　
Sincerely,
