BAD MORPHOLOGY - TO DO IVF OR NO?

Hi, this is my first signing to any forum ever but I've got tired or hiding. My short story is: I'm 40, dh - 35 and after 4 IVF (only 2nd got to 12 weeks in 2005) and 5 years of ttc we are at the beginning. Last April I had laparoscopy for severe endo after we've tried our 4th IVF last august - no success. Now, we've been told my husband has bad morphology.
Motility - 10   suppose to be >50% (but processed 2 hours after collection)
Count -    2                         > 20
Morphology - 80% abnormal <40% (I guess this means still 20% normal, right?)
I think my tubes are opened and our doctor wants us to try another IVF cycle. We are both this month on antibiotics to clean mycoplasmic bacteria and been told not to even try to concieve (conceive) naturally. Does anybody know why? Dr put me for months on DHEA since I was slow and low responder. I've read that if you have open tubes IVF is not that successful. This time I'm thinking to do IUI. However, I've got lost, almost lost hope, not sure what to do anymore specially with my husbands recent result.
Do we actually have any chances naturally or for better chance go for either IUI or IVF? Any help deeply appriciated.

Dear cudo,

I really don't know what to say except to talk with your Dr & ask him everything that concern you & your DH. Your DH can do another semen analyze after few months, ask your Dr. are there any other tests about it. The bad semen morphology can became better using same medicals, vitamins (for ex.: vitamin C) & food (spinach is very good also), ask your Dr about it. I know this since my DH have low sperm motility. IUI can also be successful as IVF. So ask about it also.

I wish you all the luck & success on your way. God will bless U with the baby angel!!:)

Take care, believe in God & pray.
Hugs,
