Will Removing Blocked Fallopian Tube Help This Patient Conceive?

Question:

Hi again Dr Ramirez, it's K. in NY.

I have written in the past about my multiple miscarriages/chemical pregnancies. I tested positive for the MTHFR mutation this past fall. I had a miscarriage at 9 weeks in August, which you believed was most likely due to a virus I contracted. I have followed up with a new specialist recently, and received some new information today.

First of all, my right tube is definitely blocked (although most of my miscarriages/chemical pregnancies resulted from ovulating on the right) We are led to believe that I most likely had a few early ectopic pregnancies. The specialist today suggested that I undergo surgery to remove the right tube completely. I am not sure how I feel about this, as surgery for any procedure is risky. Do you feel that having the tube removed would increase my odds of becoming pregnant? I am willing to do it if it makes sense, but hate to do it "just because". I am not sure if research supports this practice or if it doesn't really make a difference in the long run.

The second piece to this scenario is that my husband was diagnosed with a translocation between chromosomes 11 and 13 (46xy,t(11;13)(q21;14)). IVF (in vitro fertilization) was suggested to us, but we do not have the money for this and it is not an option unfortunately. Our Dr prefers to remove the tube and discuss fertility meds and other options after that point. While it explains many of our losses, I am curious if you have any other treatment suggestions. We have two healthy children that we had no difficulty conceiving. I have taken femara multiple times (pregnancy x1) and progesterone. We have not tried IUI, but were wondering if it would be of any benefit. I am just confused with all of this new information as to how to proceed conservatively. I am willing to take meds and try IUI, but I would rather not have surgery at this time unless there is a strong link between increased fertility and tube removal. Also, if we continue with meds and u/s, is there a point in being aggressive on months where I ovulate on the right?

We are just looking for the best path to take and I am hoping that you have some input to help us make an informed decision. Obviously this journey gets more difficult with every diagnosis. Thank you for your time.

Answer:
Hello K. from the U.S.(New York),

So sorry about your secondary infetility problems. To begin, there are no studies to either validate or invalidate the recommendation to remove a nonfunctioning tube unless it is blocked at the fimbriated end (called a hydrosalpinx). In that case, it has been shown to decrease pregnancies via IVF and is thought to impair implantation. It is recomnended to remove or separate the tube from the uterus. However, your doctor's recommendation is not unreasonable. Considering that it is not predictable as to which tube the egg will go into, each month you have a 50/50 chance that the egg will get picked up by the wrong/damage tube, and therefore will not get pregnant. In addition, you are risking ectopic pregnancy should the sperm get through on that side. I think that removing the tube might give you a better chance at getting pregnant because that only leaves one tube where the egg can go, and it does not matter which side the egg is ovulated from. They all go into the culdesac where the tubes lie.

In terms of your husband's translocation, that certainly can be a cause for miscarriages, just as your postive MTHFR can be a cause. There are no real good solutions for his problem other than doing PGS (preimplatation genetic screening) in conjuction with IVF. You'll just have to take your chances. I am not sure that IUI will offer you any more than trying as you have been, but statistically it does give a slightly increased chance of pregnancy if 2-3 eggs are ovulated at a time. That's the only advantage.

Good Luck,

29 Yr. Old IVF Patient Told She Has "Bad Eggs", Husband Has Balanced Translocation


Question:

A bit of history...2 miscarriages in the last 2 years. We were referred to an RE who did testing and found that my husband has a balanced translocation. We were advised to do IVF with PGD - I had no apparent problems. Our IVF cycle resulted in 10 eggs, 7 fertilized, 3 made it to day 3 for pgd and stopped dividing later that day. The PGD revealed very abnormal embryos with multiple trisomies and some chromosomes with only 1 copy.

The dr said I must have bad eggs - he indicated he was very surprised because all my levels were normal and I'm only 29. he has suggested donor eggs. I'm wondering if I should try another protocol or just go along with the donor eggs. I feel like I'm too young to have bad eggs but since no embryos lived there must be something wrong right?

Any advice would be greatly appreciated!

Answer:

Your history is a little odd, because for someone your age, I would have expected a better outcome in terms of the number of embryos to test. It is most likely that the abnormal embryos are coming from your husband. Not you. I think, unless finances is a problem, I would continue trying. You will eventually have a good embryo, and hopefully, a subsequent cycle will give you more embryos to test. You were not stimulated very strongly and could be. Because of the poor embryo development, I would try to get you to produce 15-20 eggs. That will probably require more medications. PGD can be done to check the embryos with subsequent cycles to see if they are chromosomally normal or not. Keep in mind though, that recent studies have shown decreased pregnancy rates with PGD, probably due to embryo injury or affects from removing one of the blastomeres. In other words, you may harm a potentially "good egg".

If you go another 2-3 tries and still no normal embryos, then I would suggest you consider donor sperm with IUI. You could do IVF but that would be much more expensive. I would think that if you persist in having abnormal embryos it is because of the abnormal sperm. That is why I suggest donor sperm. If you are dead set on having a genetic child from your husband, then you will just have to keep trying using IVF.

I don't agree that your outcome in the first cycle is a sign of bad "eggs", especially at your age.

Good luck and try to keep in mind that you do have options.
