IUI w/o assisted meds?

My husband and I have been trying to conceive for over a year now. He has testosterone issues and we were recommended to a RE. She recommended that I go for a HSG (this Tuesday) and will do an <a href="https://glowing.com/glow-fertility-program">IUI</a> this month after I ovulate. I see many people whom have done IUIs on here but it seems like everyone is taking meds/injections. Has anyone had any experience with an <a href="https://glowing.com/glow-fertility-program">IUI</a> w/out taking meds? Any success stories? :-)
