If you were my patient, I might try intrauterine insemination first. Clomid can be used to raise the sperm count in men too. IF IUI didn't work--if after the sperm wash, the counts were not much better. I would recommend continuing on to IVF. With IVF, the doctors can take a single sperm and inject it into the egg, so low sperm counts and immotility can be overcome in that way.
Hope this helps!
