I was recently diagnosed with Stage 4 endometriosis and have been taking thyroid replacements at 175 mcg/day. I had heard that having low thyroid levels or being hyperthoid causes infertility. If this is the case could I be a prime target for infertility. as I am currently seekin an infertility dr. to discuss IVF treatment to try and concieve. I can get you my levels, as I don't have them right now, but I do know they are low. ________________________________________________________________ Thyroid messages contain only the opinions of their authors.
