my husband had low motility also. We did a few IUI's with no success. I had the HCG (dye) test done to check for any blockages. Finally, we focused on good health habits, diet and exercise and just got our minds off of trying to conceive. After about 9-10 months of trying, we got pregnant with my son in April of 2007. When he was 6 months old we started trying for #2 and this time I used a fertlity monitor and was pregnant two months later with our baby girl born April 2009!
Just keep trying, for us I don't think we really ever had a fertility issue, it was just pinpointing that tiny window of opportunity each month. Good luck!
