Semen Analysis

Hi Dr.
My husband just received his semen analysis results. His count is 331 million with 82% motility. Which is still very good, leaving us in the mid 200 million range.

I am confused and very concerned about his morphology and am looking for some clarification. The report said 4% morphology. Which from what I read is still within normal range according to their WHO guidelines. However, it said the head abnormality is 80%, tail is 10% and neck is 5%.

Are these numbers reflected in that 4% morphology calculation? Or is it 4% morphology PLUS these numbers above which makes the total number of normal sperm lower?

What are you thoughts on his fertility potential?
