Hi! I have low AMH, which is part of the low ovarian reserve diagnosis. I've also had multiple losses (all while TTC #2). We've seen two RE's who both recommend IVF. I felt pretty discouraged when we got the news too and it's hard to believe we're moving on to IVF. My RE seems pretty optimistic though, so I'm just going to hope he's right.
My first RE didn't think DH needed to have an SA done since we were clearly getting pregnant. The 2nd RE did run the SA on him, and it did come back perfectly fine, but it was good for our peace of mind to have it done.
There's also a DOR check-in on the Infertility board for ladies with dominished ovarian reserve. I've lurked there a few times and gotten some good information.
