Sperm count

So on the day of my <a href="https://glowing.com/glow-fertility-program">iui</a>, the nurse briefly went over my husband’s sperm count with me and she advised that it was 5.99 million after the washing of the sperm was complete. She said that’s good, because anything above 5 million is what they are looking for. Anyone else have any input on this?? Thanks!
