Thank you all for your suggestions.

My DH's infertility is apparently genetically caused and FS says there's nothing that could really help. That's why she said she personally would go straight to ICSI. See my DH is majorly below average in most areas tested regarding his sperm.

But i have researched supplements and vitamins that are supposed to help and have my DH taking them.

I think i might just give it a couple of months - and then give it a try...
