Sperm grade 2

After 5 failed IUIs my husband and I have decided to take a break. Our issues are with male infertility. His analysis have been decent. He ranges from 53-20million pre wash. We are now trying back on our own for awhile before considering IVF (which I really don’t want to do). I was always told it was his sperm count. Looking into his paper work he is at grade 2 for his motility. More or less they are swimming around each other and not fwd. Just wondering if anyone has had luck doing this on there own with the sperm motility being at a 2. Thanks
