Male infertility?

My husband and I have been TTC for over 2 years. We recently started our infertility appointments a few months ago. I've done blood work and ultrasounds of my ovaries. I've came back good and okay. My husband has done a sample and his motility is...low. We will be seeing a urologist the next hitch he is home. My question is...has any couple experienced male infertility and have had success conceiving?
