Thick viscosity?

Hey ladies, my DH & I had a post coital this am after being on 2 rounds of femara & it not working. I took femara again this month but looks like we're not able to get pregnant because DH's swimmers aren't getting where they need to go. Anyone else ever had this problem?! IUI is definitely the next option & we have discussed it but after today DH is frustrated & upset. I think he's just feeling guilty because it's an issue with him. Idk what to say or do to make him feel better! I've tried everything...I think he just needs time to process the news. I don't want him to feel like I don't love him bc of this, I could've just as easily been the one with the problems. :(  I feel bad for him! Help please!
