First RE appointment

My husband and I are getting ready to have are first RE appointment next month. It's been 3 years ttc and 2 miscarriages, I am desperately hoping for answers when we go 🙏🏻 our doctor seems to think iui will work for us only thing they have been able to determine is my husband has low count and low motility but everything normal with me... I guess I'm looking for any advice on what to expect with iui an the RE apt! Any advice is welcome!
