My husband is sterile.......

I have no idea what to think. I was diagnosed with pcos last year. I'm not ovulating. So my ob sent us to a specialist. he confirmed everything we try a few rounds of trigger shots. fast forward to this past week. Nothing has worked to help get pregnant so they do an analysis on him. he is sterile. I'm so lost. We are lost... he goes for further testing to figure out why and if there is something we can do. has any one else went through this??
