Why does a FSH level of 8.0 mean IUI is not the best form of treatment?

My wife has just undergone an IUI process through the NHS despite having a 2nd day FSH level of 8.0. I use the term despite due to the fact we have been told that we will be removed from the IUI process due to this FSH level and will have to undergo IVF. Why is this the case, and if the FSH level is such that IUI is not successful why did we have to go through the IUI if they knew it wouldn't be successful?

It is difficult for me to comment on your situation as I don’t know any of your medical history and whether IUI is the most appropriate treatment.  Your wife’s FSH is near the top end of the normal range and the appropriate treatment would depend on other factor such as her age and previous history.  Each Centre has its own treatment policy and I would suggest you go back to see your specialist and ask for an explanation as to why they are advising you to proceed to IVF as it may be other factors than just the FSH level.
