Hi Jen and welcome to BB.

It doesn't sound like your specialist was very hopeful but they did suggest it so maybe it is worth a try.

I know that you say that you aren't sure how your DH would cope with the disappointment if they can't find anything but maybe it would be the little push that he needs to think about other options and if they find something woo hoo! There is a possibility that there are some there but for whatever reason they aren't making it our (lack of strength etc).

I'm not in any way trying to push you towards having the biopsy if your DH doesn't want it but I am a no stone unturned kind of person and it would do my head in knowing that I hadn't explored every option.

I'm sorry that I can't tell you about the costs - but your specialist's receptionist would be able to tell you.

All the best - and don't be a stranger - we are always here to have a chat - the disappointments associated with long term TTC are well known to many people here on BB.
