How do I help my hubby?

First time poster here.

We have been trying for 9 years with no luck. I've gotten blood work, ultrasound, and x-rays and every test came back perfect. My hubby is getting tested on the 19th and I can tell he is super nervous and unsure of himself. We have talked in depth about it and our options no matter what the test results are but he still seems really worried. I would love any advice on how to help him! I don't want him to feel guilty if there is something wrong with him or its his fault.
