I had my TSH result back yesterday and it was 4.05, which my doctors feel is in the normal range.
I have been told by a private IVF clinic that they would like my TSH to be 2.5 before commencing treatment. I have previously had 3 miscarriages and feel that my thyroid function could be a contributing factor to this.
Am I eligible to start any treatment and how would I approach this with my GP?
My mum and both grandparents have thyroid problems too.
Thank you In advance

Of cours a TSH of 4.05 is in the so-called 'normal' range. You don't have to be a doctor to see that. But it's far from 'normal'. A 'normal' (euthyroid) TSH would be around 1, never over 2 and you're hypo when it gets to 3. So, it's more than likely that your thyroid function - or lack of it - is what is contributing to your fertility problems. Your GP should know that.
I really don't know how to talk to doctors, they're a funny breed. You can never tell how they're going to react. But, try telling him that you want to conceive and your clinic wants your TSH down to below 2.5 before starting treatment - which is a perfectly normal request. Or, better still, get the clinic to write to him.
It says TSH should be below 2.5 pre conception…..but it’s not clear if that’s ONLY for patients already on levothyroxine. Frequently that’s how GP’s interpret it
TSH over 3 is indicative of thyroid struggling
