I've read on a few threads about how thyroid levels can affect fertility and given that we're clutching at straws having suffered with unexplained infertility for 5 years I thought I'd have my thyroid level checked. Well it's come back as 2.5 which is in the normal range but I believe for TTC it ideally needs to be below this. So my next question is does anyone know of ways to lower it without medication is it something that could be weight related?
