Husband's high white blood cell count + Crohn's disease....

He had bloodwork done for something unrelated to TTC but they called and wanted to retest cause he had a high white blood cell count. They think it was just because he was having a Crohn's disease flare up (now it is better) but they're checking to make sure it is okay and not something worse. Anyone ever had something like this & have issues conceiving? I worry that his crohns will affect it but then read about the high white blood cell being an issue when it's in the sperm. I'm guessing if it's in his blood it would be in his sperm right?
  I wish he would get everything checked out but he says it's embarrassing and unnecessary (this will be my 4th month). Hopefully I'll be able to convince him to go 😔
