Where do we go from here?

My husband and I have been TTC for about 2 years now. We decided last summer that we needed to start seeing a fertility specialist. I have been able to knock out all of my testing (blood work, ultrasound and HSG.. all normal). My husband had his second SA today and the results came back low again (first SA was 12 million and second SA was 9 million). He’s crushed and now he just wants to give up with any doctor help. I don’t even know where to go from here. Any suggestions?
