Low sperm count! Help us find a cheap fix!

Do anyone have a SO with a low sperm count? I know I can get pregnant because I have terminated a pregnancy before due to many reasons, and now that my husband has been trying, im worried that he may have a low sperm count. We talked about going to a fertility clinic, but as some research mentioned, it can be very expensive. Anyways, I just want to know what (if the problem of your SO sperm count increased and pregnancy resulted) what were the steps and/or pills used to boost up the sperm count? Ovulation is coming soon, and I want to explore our options before having to spend a lot of money.
