Low Sperm Count>> Advice appreciated

We just found out that my husband has low sperm count. He has been tested twice and our Doctor wants to send us to a fertility clinic in another town where they can help him. Is anyone familiar with this certain procedure>>  "Intrauterine insemination" (<a href="https://glowing.com/glow-fertility-program">IUI</a>) where the sperm is taken from a man and ‘washed’ to separate the healthy sperm from the unhealthy sperm. This is then inserted straight into the womb of the woman. This practice is commonly known as artificial insemination. 
⭐️I believe this is the route they will make us chose because the other>> "<a href="https://glowing.com/glow-fertility-program">In vitro fertilization</a>" (<a href="https://glowing.com/glow-fertility-program">IVF</a>) ⭐️ doesn't sound like it pertains to me since I don't have problems ovulating and I get my period every month regularly. But I could be wrong. So if you have information about these treatments I would like to hear about them so I can at least have an idea on what's about to happen next. Thank you!
