Hey man, I'm not a healthcare professional, but those numbers actually seem mostly within the normal ranges based on what you've posted. Your sperm count and motility look pretty solid. The 30% sperm abnormality is actually better than the reference range of 40%. However, the morphology—variation in size of heads and/or tails—could potentially be a concern.
Given that you've been trying for a while with no success, it's definitely worth having a sit-down with a fertility specialist to go through these results in detail and discuss next steps. They might recommend some lifestyle changes, medications, or further tests. Best of luck to you and your wife on this journey.
