Semen analysis

Brittney • Graphic designer turned CNA trying for baby #1.

My sister suggest that my boyfriend take a semen analysis, since we're having trouble getting pregnant.

I've always thought the problem was me, not him. I don't know though, my period is regular 99% of the time and ovulation tests show high fertility...

What do you guys think? And what can we do if there is a problem with his sperm?
