Low motility - next steps

My husband got his SA and he has plenty of sperm but their motility is low. The doctor says we can still get pregnant on our own, but we also have other options such as <a href="https://glowing.com/glow-fertility-program">IUI</a>. He also suggested my husband going to a urologist. I basically just want to know if anyone else was in this situation and what route you decided to take first and if there was anything you wish you did differently. I am waiting to have an ultrasound next month to make sure everything is good on my end, my blood work with my hormones all came back normal.
