semen analysis

Madi
Can a semen analysis provide any insight/reason behind multiple miscarriages? My doc did all the testing possible on me but everything came back normal so she recommended hubby see a urologist but when he went the urologist said if he had defected or low sperm we wouldn't have been able to get pregnant at all without assistance. Does that seem right or should I push for it anyways? I have two kids from a previous relationship but he doesn't, we have had three miscarriages in the last three years.
