Morphology and TTC

My husband had an SA back in April and had 3% morph. His count was over 285 mil and his motility is always in the 75-85% range. We put him on a ton of supplements and he got up to a 6% in July. Just had him retested this month and he’s back to a 3% again. My RE is now sending us to a urologist. Not sure what to think anymore. Anyone had up and down results like this and still conceive?
