Sperm analysis results

Sk

My husband called to check on his lab results from semien analysis and all they said over the phone is that his sperm mobility is at 35.. normal is 40. So what EXACTLY does it mean? We have been trying over 8 yrs. Please someone explain it better to me. Does this mean we can still have kids... or not. He is 34 yrs old btw we both have no kids yet
