My Sister Has Ovarian Cancer: I Want To Be Her Surrogate, What Is The First Step?


Question:

Hello. My sister has been diagnosed with Ovarian Cancer and is going to have a hysterectomy. We have discussed it, and I would like to carry a baby for her using her eggs and her husbands sperm. I live near Ottawa Ontario and she lives in Calgary AB. I was wondering what the first step would be, and who we should call to get this process started before it is too late.

Answer:

Hello C. from Canada,

I am sorry to hear about your sister, but the good news is that we do have the technology to help her have a child in exactly the way you mention. It is called IVF (in vitro fertilization) with surrogate. Your sister needs to contact an IVF center immediately. They will then have several options: the eggs can be removed to be fertilized and used later, or she could go through the IVF cycle completely and the fresh embryos placed directly into your uterus. In either case, you would be the surrogate. An IVF cycle will take two weeks minimum, so she will need to do this quickly, before her surgery. With ovarian cancer, you don't want to delay much.

The infertility specialist should coordinate things with her Gyn oncologist so that everybody is on the same page. Once the eggs are removed (egg retrieval), she can then undergo her surgery. Stimulation should be strong to try to retrieve as many eggs as possible so that any residual eggs/embryos can be frozen for later use if the first cycle fails or for another sibling. The IVF center will advise you on your role as a surrogate, do all the planning necessary and prepare your uterus to accept the embryos.

For more information, there is a very good non-profit here in the U.S. called "Fertile Hope", (which has recently been acquired by Lance Armstrong's Live Strong organization). This organization has a lot of information regarding cancer patients and their reproductive options. There is a section on the website for healthcare professionals that I have used called "Options At A Glance", which gives you a good idea of all the methods available for fertility preservation. See this link: http://www.fertilehope.org/ .

This is a wonderful thing that you are trying to coordinate and the best of luck to all of you!

Secondary Infertility, High Responder PCO Patient: Why Did I Fail Two IVF Cycles?


Question:

Hi, I am 28 years old and my husband and I have a naturally conceived 3 year old son. We are dealing with secondary infertility. We have gone through 2 IVF cycles.

1st IVF/ICSI cycle-21 eggs--11 fertilized (70% fert. rate)--transferred 2 great 8 cell embryos. None to freeze. Negative result

2nd IVF/ICSI cycle
19 eggs--(85% fert. rate)--8 embryos on day 3
1-8 cell grade 1 (best)
2-8 cell grade
21-8 cell grade
32-7 cell grade
22-5 cell grade 2

No transfer because of lining issues. Did one FET--ended in a chemical pregnancy.

My question--do I have poor egg quality? Lab results said some eggs were abnormal, with thicker zona. Any hope to go through IVF again?

I'm from Fargo, ND. Thanks in advance!

Answer:

Hello M. from North Dakota,

From the number of eggs retrieved, I presume you also had a high number of follicles (>20). That indicates that you are responding like a PCO patient, or have PCOD. Studies have shown that there is a decrease in pregnancy rates with PCO patients, probably due to a high number of immature eggs retrieved. It also seems to affect egg quality. That is not because you have abnormal eggs, it is probably because the PCO causes an inefficiency in egg maturation.I would not give up hope. In fact, I would encourage you to continue trying because you will be successful. It may take some more tries, and hopefully, your doctor will adjust your protocol to try to reduce your stimulation. It would be better to have fewer follicles with good eggs than lots of follicles with poor eggs.

By the way, I just had a patient from your end of the country, Montana, that previously went to a clinic in Washington state and had two failed IVF cycles. She was a secondary infertility patient as well. Well, the change in weather or location or clinic did the trick because she became pregnant with one attempt, and with twins. Infertility Physicians and clinics are not all equal. That may have a bearing on your success as well. I am worried about the fact that despite all the eggs, your embryo quality rate and number to freeze were so low. That might also indicate a laboratory issue.

In any case, don't give up hope. You will eventually be successful.

Good Luck,

More Questions Regarding IVF and ICSI: Can I Have Twins, SET, And Other Post Retrieval And Transfer Questions



Question:

Hello again, this is S. with some follow-up questions from my earlier email.
Thanks for answering my questions. I have a few more. I know that obviously it depends upon the number of viable eggs removed during egg retrieval for IVF with ICSI but how many of the eggs would they try to fertilize and use at a time? How does it work with the frozen embryos? What are the chances of twins or triplets with this type of procedure? Can I decide if I want twins if I have more than 1 egg that is ready? After the egg is fertilized and put back do I have to be off of my feet for a time? How long does it take for the process to take place?

Sorry I'm just really unclear about all of this. Do I have to go back for ultrasounds afterwards and if so how often do I have follow up appts? Thanks again!

Answer:

Hello S.,

You're welcome to follow up with additional questions any time. I probably did not address the ICSI (intracytoplasmic sperm injection) question you had in your first email. With ICSI, all mature eggs are injected since not all with fertilize. If they only took a few and did ICSI, which I understand some clinics will do, that could impair the number of embryos you have to work with if they don't fertilize.

These are then allowed to divide over a 3-5 day period. An appropriate number is then chosen to transfer. That number is decided between you and your doctor. With frozen embryo transfers, the embryos are thawed, allowed to expand, and if they survive, are transferred. Usually the number thawed are the number transferred because re-freezing is not necessarily a good thing.

If three embryos are transferred, the risk of twins is about 35% and triplets less than 10%. This risk declines as the number of embryos transferred decreases. Because of the high pregnancy rates these days, many clinics have moved to doing a single embryo transfer, or SET, in order to minimize the risk of twins or more. This is based on new recommendations that have come out from the American Society for Reproductive Medicine and the Society for Advanced Reproductive Technology. There has been strong political pressure for IVF centers to reduce the incidence of a multiple gestation (twins or more). If you want twins, then you have to discuss this with your doctor and see if that is something the doctor feels comfortable with. Depending on your age, either two or three embryos would be transferred to try to achieve twins.

Once the embryos are transferred, you do not have to "rest" for any period of time. I have my patients do light activity for three days after the transfer to allow for implantation to take place, but I do not want them to be at bedrest. From that point it is a natural process and is the same that your body would go through if you were trying on your own.

In terms of your last two questions, these are answers that you should be getting directly from your IVF center. You pay them a lot of money for this procedure and they should be giving you almost royal treatment. If they are not, then you should demand it. The IVF process is a three week process, basically mimicking your natural process. The ovaries are stimulated, which takes 10-12 days, the eggs are retrieved at the mid-cycle and allowed to fertilized, then they are allowed to grow in culture for 3-5 days, then they are transferred back into the uterus. 8-10 days later a pregnancy test is done, which usually coincides with the end of the month if you started at the beginning of the month. (You should check out my website and I have an outline of the IVF process.) In the first 10-12 days, ultrasound and blood tests are done periodically to evaluate how you are responding, how many follicles you have, how big the follicles are and when to trigger for the retrieval. These ultrasounds can be done daily, every other day or farther apart depending on how big the follicles are and how close you are to the trigger day (generally as you get closer, the appointments get closer). The egg retrieval is usually done two days after the trigger (35-36 hours from the trigger injection) then the transfer is done 3-5 days after that.
