Hi Doctor,

I am trying to conceive for the last 10 months or so. My TSH level was 7.5 in September, 2015. My gynaecologist prescribed me "Thyronorm 25mg" & it brought down my thyroid level to 3.63, tested in November, 2015. But still I am unable to conceive, despite normal menstrual cycles & normal USG report (done in September, 2015).

Please tell me whether my high TSH-level history is a constraint for fertilization. Is it possible that since I had a high TSH level (7.5) earlier & a normal one now (3.63), I cam unable to conceive?
Also please tell me how many months I should wait or any other tests you suggest.
