So, DH has just come home tonight and told me something that's been playing on his mind for a while...

He found it very hard to articulate, but ended up being able to tell me that he's concerned about his fertility... He's felt for a while now that when we DTD he does climax, but nothing "comes out".
He's done his own...'investigating' and can confirm that nothing actually comes out.

I've asked Dr Google and a quick read looks like it could be either Anejaculation or Retrograde Ejaculation...DH is a type 1 diabetic, and both conditions can be related to diabetes. Neither looks to be a serious health issue, except where fertility is concerned

DH is feeling very down and blaming himself for being a failure. I've been trying to reassure him that it will all be ok... He wants to see his doctor though, so that's good... I don't know what to feel...

i don't really know what I'm asking here, just maybe need some practical advice, a point in the right direction. Some hope?

We had no problems conceiving DS, why is this happening now?
