I stopped consuming soy (other than occasionally shoyu, or lecithin in a prepared food) after trying unsuccessfully to conceive for almost two years. By this time, I was also taking Clomid, so it's probably the drug that worked, but I have to say, I was pregnant after my sixth try with Clomid, just a couple of months after I stopped the soy.
I can't be sure that soy was the problem at all. My reason for quitting was that I had read that genistein, found in all soy products and especially available in tempeh (which I had spent so long thinking was more healthful than tofu), can stop the egg from accepting the sperm. Since we knew we had eggs and sperm, and didn't know why they weren't getting together, this seemed like a possible cause. Now, I am still not eating soy, even though I am already pregnant, because I figure that anything that might have prevented me from conceiving can't be healthful for me or the baby.
What do you think? Did you eat much soy before you became pregnant, either right before or for years before? Did you have any trouble conceiving? Do you eat soy now, and are you concerned about the hormonal effects?
