No normal sperm

Katie
My husband and I just found out that he has 0% morphology or no normal sperm. He has good motility and a good number though. He has another appointment to test again, but I'm not feeling very confident ( thanks dr google!) 
We have a 4 year old son already and conceived him in 4 months. Not sure if we had the same issue and our son is a miracle or something has happened since then to cause the abnormal morphology. We are currently on cycle 7 for #2. 😞
Has anyone had success conceiving with 0% morphology? Within a "normal" time frame (not years and years) and without fertility treatments like IUIs or IVF?
Any info would be greatly appreciated!!
