Low sperm count

I have been ttc #2 for almost 2 years and have had all the tests done and all is fine with me.  I was even doing clomid for 3 cycles and this week just found out that my husband has significantly low sperm count.  They said they usually want 6-7 million and he has 800,000.  They basically told us our option was <a href="https://glowing.com/glow-fertility-program">iui</a>.  I am in shock bc it took us 8 months with our son who is 4, no tests no issues.  I feel like I have no control considering <a href="https://glowing.com/glow-fertility-program">iui</a> is usually very expensive.  Has anyone tried fertilaid for men and had success?  I looked at foods and he eats a lot of the foods that boost sperm counts.  He doesn't smoke anything and is in shape.  Just confused and feel like my chances are pretty much slim to none.
