I have had 3 failed IVF cycles. Thyroid levels (TSH) have all been normal. TSH of 0.59, free t3 2.79 and free t4 1.04 (all normal) Thyroglobulin antibody was elevated at a titer of 1:10. Thyroid miscrosomal antibody was elevated at a titer of 1:6,400. (nl <1:100). What is normal range for the later 2 test? Could this be the reason for my failed cycles? What should be the next course of trwatment?
