Thick semen

My husband got his results back today and they said everything looks fine except his semen is a little thick.
​The nurse practitioner said she would refer us to a fertility specialist when we moved (in the process of doing so).
​My husband asked if he was better hydrated would that help and she said it might. 
​He's active and healthy aside from drinking, occasionally. He is going to be 28 this year.
​Has anyone else been faced with this?
​Also I never make ewcm, I only get to watery... And I have an 11 day LP but my cycles are returning to normal after the depo needle.
​I'm worried that his thick semen and me lacking here and there will be a problem. We already use pressed with no success yet.
