We have had many challenges and tests. Tests are a pain but mostly easy for the guy and cheaper. We've been officially trying for 5 years. Adoption and more costly measures are up for discussion now since I am stating a new job.

You can go into the doc with a list if you do not want to bring it up. It is easier to talk about than you think. They are professionals and you are paying them to listen and help.
Good luck with all.
