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.

Good Luck,

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,
