If you had no male factor would you opt for IUI or TI?

Background: We have completed 2 medicated cycles with TI. I am the one with issues (DOR, low AMH) DH's SA was fine. I am responding to the meds (clomid/gonal f) as expected and they have suggested we do the same protocol for another cycle.

I inquired about IUI and they said it was up to us if we wanted to do that instead.

So I was wondering if anyone has done TI and switched to IUI and if so for what reason?

Did the IUI prove to be successful? Or did you stick with TI and have success?

My RE said it's hard to tell if IUI would be more successful or not....
