Sperm Count needed. So confused- HELP

Hi Everyone,

I need some desperate help! How do they measure the amount of sperm required as a minimum for <a href="https://glowing.com/glow-fertility-program">IUI</a>? Is it measured by the ml or total motile sperm count per ejeculate?

Example: if 10 million per ml present and 3 ml produced = 30 million x by 65% motility = 19,500000. Would 19.5million be the post wash sperm count considered???

So confused!!! Any help would be great!!!
