It is so nice to meet you Diana. I am also new in this forum but I think I can offer some solutions. First of all, I am sorry for what you have been going through. Having your thyroid glands removed. Also for the cyst. I think the cyst did lead to the fallopian tube blockage. I am not a professional in this but I once had a fallopian tube blockage. For me, I had a surgery. But I think ways to solve these are different. Now that you are on pills instead. It is my gesture that your will take kind of long to be solved. Anyway, as far as at the end of the day you get a solution. About the thyroid, sure, it does affect fertility. But since yours was removed, I don’t think if it posses the same threat. Mostly infertility will be caused by malfunctioning of the thyroid. But currently you don’t have one. This means that you are safe. However, we cannot conclude for it may also cause some different kind of problems too. However, I am wishing you the best in your search for a baby.
