Is it possible that a successful pregnancy could ‘teach’ a body / hormone system how to have relatively normal cycles? After years of non-ovulatory cycles due to PCOS, and 10 IVFS, I have now conceived naturally three times since then. I don’t believe it is because I am ‘just relaxing’. It feels to me as if my body has finally figured out what it is supposed to do. Is there a medical explanation for this?

This is a known phenomenon and is wonderful. We however do not have a good scientific explanation for this.

What is the 3 day vs 5 day transfer dependant on? When and why do you decide to do one over the other?

Sunday, November 9th, 2008

It depends again on where you are doing your ART. Some clinics, especially in Germany, only do day 2 ET’s for example. Some only do day 3 and others day 5 and somewhere in between all of the above, some do day 3 and day 5 transfers depending on the embryology.

I did a long protocol IVF with lucrin and 12 out of 13 retrieved eggs were immature (matured in lab). I felt awful while taking the lucrin, blood pressure was high, dizzy and swollen ankles. 2 blasocysts (one hatching) were transferred, but resulted in negative. My FS has recommended the Cetrotide protocol for my next IVF. If this is a new protocol, why is long protocol and lucrin still the preference for one’s first IVF? What are the chances of mature eggs from cetrotide protocol if long protocol resulted in mostly immature eggs? Could the reason for so many immature eggs have been because lucrin had a negative effect on my body?

Cetrotide protocols are not new. It has been around for quite a few years now. About 65% of all cycles worldwide however, are still Lucrin cycles. This is probably due to the fact that Lucrin has been tried and tested for many years , having given good results for many years. The availability of Cetrotide has given us more options and the ability to change protocols where required.

There is no guarantee that the cetrotide will lead to a different outcome, but is worthwhile doing if indicated. It is unlikely that the reason for the immature eggs was the Lucrin – it could be that it was just a particular bad cohort of eggs or ovarian dysfunction

Due to severe endometriosis my ovaries have been damaged and I do not produce many eggs (4-5) when stimulated. However, fertilasation has occurred in both of our failed ivf’s, first time there was only one embryo to transfer, the second time there were two. Both were day 3 transfers and good quality embryos but both resulted in bfn. If there are no immunological issues at play, would it be advisable to let the embryos grow until day 5 to see if there is a quality issue or should we transfer them again on day three so that they get quicker to their natural environment? I.e, is it possible that if a day 5 embryo degenerates in vitro, it would have possibly survived in vivo?

ART is unfortunately not an exact science, and it is therefore difficult to predict whether the embryos will do better being back in the uterus on day 3 or stay in the dish ‘till day 5. Generally, if one has 3 or more good 8 cell embryos on day 3 , one can safely grow them to day 5 without the risk of not having nothing to transfer on day 5. If there are less than 3 good embryos on day 3, it does not really make a difference as to whether you transfer on day 3 .

What exactly does a very high AMH mean? What causes low AMH and can it be prevented?

Sunday, November 9th, 2008

AMH is an indicator of egg quantity and indirectly, possible egg quality. A very high AMH is more likely than not an indication of underlying PCOS. A low AMH is an indicator of diminished ovarian reserve volume and can not be prevented as one can not stop one’s biological clock. It is important to remember that AMH is just one of a few tools in order to establish ovarian reserve volume and should be interpreted in conjunction with all the other tools available.

How safe is glucophage in pregnancy? Can it be used the whole way through pregnancy? Could you please ask Dr V to elaborate on the Glucophage Question especially what dosages are safe? Or should you be taking the same dosage as while TTC?

Sunday, November 9th, 2008

There was a time when it was thought that metformin was not safe during pregnancy. However, subsequent studies have shown that it does not seem to pose any problem and is therefore used more and more in PCOS patients. Research have also shown that while on metformin during pregnancy, the incidence of developing glucose intolerance and abnormally large babies is significantly less. The dosage is the same as during that of TTC and is generally 1500mg per day in two to three divided dosages .

“I’d like to ask the good doctor about (elective) single embryo transfers. Is it only recommended/worthwhile if there is a “perfect” day 5 blastocyst available for transfer? What “grade” should the “perfect” blast be? How much is the success rate affected if the embryo selected for transfer is an “early blastocyst” by day 5 (i.e. not quite a blast but on it’s way to becoming one)? How significant is it if the patient has no “perfect” blastocysts for transfer? Is it unlikely that the embryo selected for transfer will continue to develop and implant? If a patient had 2 “early” blastocysts on day 5 , would you recommend that they rather transfer the 2 knowing that it is unlikely that both will take? As background, the patient would want to avoid the possibility of twins almost completely, while still ensuring a high degree of success for the IVF cycle. The patient has had a normal fullterm pregnancy (resulting in a live baby) before and the only fertility problem is damaged/blocked fallopian tubes.

The world is at present ,divided with regards to single or double embryo transfers and is much dependent on where you happen to find yourself in the world when doing ART. The only way however to try and ensure a singleton pregnancy is doing an elective SET.(There is a possibility of 0.8% of a single embryo leading to an identical twin pregnancy)A few factors have to be taken into consideration though, before embarking on an elective SET namely:
1)    Age
2)    Number previous attempts
3)    Reproductive history
4)    Embryo quality on the day of transfer
5)    Successful freezing program of the clinic

It is therefore clear from the above that the decision as to whether or not to do an elective SET is not an easy one as one would aim for the best outcome of being pregnant when presented with all the facts.

I would like to know, when do Drs start testing infetile couples for autoimmune disorders. Do they test for them before a couple undergoes IVF or only after a couple of miscariages? Lastly what indicators could possibly signal autoimmune issues.

Sunday, November 9th, 2008

Testing for autoimmune disorders in infertile couples will depend on whether there is an indication to test for it and will not be done on a routine basis. The main indications will be:
1)    Recurrent miscarriages
2)    Repeated failure to implantation following IVF/ICSI
3)    A history of autoimmune diseases such as rheumatoid arthritis, autoimmune thyroiditis, etc.
