I am not sure what type of thyroid condition you have, as I don't know enough about it. But I have Hashimoto's Hypothyroidism, my count was 6.98 and it is supposed to be under 2. My GP sent me to a specialist, who was great, and I've been on thyroxine for almost 2 years and my last blood tests showed 1.77. So, if an underactive thyroid can make someone 'infertile' then an over active one probably can too.
I'd ask your GP. Mine is excellent and really tells it how it is.
