Thyroid levels for fertility

justju profile image

Hi all

I have had 3+ years of fertility problems, with tests showing it as "unidentified". I have had a miscarriage.

I'm now trying to do as much research into the causes myself - does anyone know the recommended Thyroid levels for conception - the case study below seems to suggest a TSH of 2.

The resources under the Guideline section appear to be for early pregnancy/post-partum and not the optimum levels for getting pregnant. Here they suggest under 2.5.

I would appreciate any advice - I am visiting my GP Wednesday to get my Thyroid test results, but my results from early 2017 (several months re-miscarriage) was at 2.5. I'm at a bit of a loss really!

For full Thyroid evaluation you need TSH, FT4, FT3 plus TPO and TG thyroid antibodies and also very important to test vitamin D, folate, ferritin and B12

You are unlikely to get all these from GP, but suggest you ask

You can have high antibodies and/or low vitamins and "normal" TSH and FT4.

Private tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies or vitamins

Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw. Both companies often have money off offers.

All thyroid tests should ideally be done as early as possible in morning and fasting. This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, GP will be unaware)
