Lab values

Does anyone have a reference they use for "normal" or ideal lab levels? I had a ton of blood work on CD3 and now have all of my results. In the past, we've had male infertility, hubs is on clomid and his sample came back pretty good! He used clomid to have our first and we were able to conceive #2 (live birth) and #3 (MC) on our own. It looks like maybe my labs are on the lower side (I'm almost 37YO). I was waiting to do the procedure where they look at the tubes and such because I thought I really didn't need to do it. I also didn't want to start BC to do the test since we are still TTC... but I'm wondering if mh labs are low enough to really move to the next step.
