Ask him what he wants to do about it, because if you start pushing him to get answers, it'll probably only end in an argument - because I know with my DH if I push him to go to the Dr for anything, he gets cranky at me!!

The best thing you can do Ree, is to just be there for him and listen to him. You will get through it together.
i agree totally.

you can't NOT bring it up at this point - it will become the elephant in the room and the longer you don't talk about it because you're scared to upset him, the harder it will become to bring it up kwim? tell him you've been thinking about it, and what does he want to do? what does he need from you? does he need to talk about it or would he rather just not talk for now? speaking to you is going to be very different to talking to the GP. keep your approach respectful and gentle - don't give him empty platitudes though cos it doesn't help! nothing worse than "we'll be right" (the bug bear comment from DH lol)

you may want to talk about the fact that you're ttc. that is going to put a huge amount of "weight" on him when he is feeling like he is. can you perhaps agree to put TTC on hold for a while to give him a chance to talk to the GP (and potentially the urologist) - take "sperm" out of the equation for the time being. allow any physical intimacy be purely about the two of you, and not the deposit at the end, to take the pressure off him. the last thing you want or need at this point is for him to think he's told you what is going on, you only want the sperm, and to lose the physical intimacy in your relationship, making it worse for him. as well as the feelings he is having at the moment in regard to worrying about the physical, there is a very real chance he is feeling guilty about the ttc thing as well. i know when we got confirmation that it was me that was the cause of all our issues and DH was fine, the weight of that was HUGE. just something to keep in mind
