What test should we request to help us conceive?

First you and your partner should really talk about this because some of the test or procedure can be a bit uncomfortable especially with guys...ego....if both of you are open to this idea then I suggest you both do a fertility test, for guys:sperm analysis...then for girls:should consult ob-gyne to help her with not only the test but with counseling on what you should and shouldn't do....but what's important is its not how much you really like to conceive but no matter what the result might be you should still value each other, respect each other more and love each other more...

How I met wih you

I would go to a fertility doctor. Check both the man and women.
