Go with what your RE says. Typically, IUI is called for, as it is inserted further up into the reproductive stuff into the uterus vs. the ICI is into the cervix only and requires the sperm to travel further.
We've done both. ICI is amazing if you want to do it at home (get the 1 cc syringes from somewhere... Amazon has them or if you also happen to be a scientist steal them from your lab!). We've also used a midwife to do the IUI after our donor ran out of ICI. From talking to people and seeing our friends in similar situations, both can work. Good luck!!!
