Worth it to get a sperm analysis?

My doctor has ordered me to do blood work and for my partner to get a sperm analysis. I went for my blood work on cd3 and cd21 but we’ve had 2 chemical pregnancies in the last 2 months. So I figured his sperm is obviously doing what it should and told him not to worry about bringing a sperm sample to the hospital (the chemicals happened after my doctor ordered all these tests). Well now I’m second guessing myself and wondering if he still should? What are your thoughts ladies? Could there be abnormalities in his sperm and that’s what’s causing the chemicals? Or is it likely not a male factor? I think I’ll have him do it just incase but wanted to hear your opinions!
