Hi,
After a total thyroidectomy due to papillary cancer five years ago, my TSH remains very suppressed at <0.02 with Free T4 at 1.2 (range being .7 - 1.9) and Free T3 at 4.5 (range being 2.8 - 5.3). Since my Frees are within the normal range, I could be considered as being subclinical hyperthyroid. I have no hyper symptoms at all. My current dosage of meds is 100mcg Levothyroxine with 1 1/2 grains Armour. I feel best on this combination.
We have been trying to get pregnant for three years. I have been pregnant twice, but miscarried both. I've also had three biochemical pregnancies. The general consensus among my ob/gyn and endo is that the difficulty with fertility is due to my age (age 41) not any thyroid issue. I am very active with charting, BBT, etc. I have had every blood panel, miscarriage panel, fertility test/procedure possible and all come back fine. My husband's tests are fine too.
My question to you: Could subclinical hypERthyroidism cause fertility issues? Could this be the difficulty with conception/maintaining pregnancies? Or, do you suspect it is my age, not the thyroid issue at play here? What are your overall thoughts?
Thanks so much for your help!
