Expert Q & A Answers About sperm quality

Is there a test to find out if my paraplegic fiance is still fertile?

My fiancéis a quadriplegic. He has a C7 spinal cord injury. We both want children, but we aren't sure if he can have children. I wanted to know if there is any way to find out if he can impregnate me?

How do I know if I have a low sperm count?

I’m an 18-year-old male virgin. I don’t ejaculate much...I read somewhere that it should be a teaspoon full...but I’m not making that much. Do I have a low sperm count? Should I be concerned?
