Ok so who can tell me about the thyroid? What does it do?

My mum has found out hers is totally non functioning as well as some other issues which lead to me having some tests done last week. I got the results back today saying that my thyroid results were low, so my GP wants to put me on meds for it.

My issue is that I'm on IVF meds already & I think that might have made a difference to the results. Christy mentioned in my journal that the thyroid is responsible for FSH production so the IVF meds would definitely have affected it because at the time I was on the ones that supress FSH production.

I have to call my GP in the morning to see what's going on, but in the meantime if anyone can help that would be great
