Iui with male infertility

Has anyone had successful iui with male infertility? My S/O was put on clomid last month to boost his levels as his semen analysis was not the greatest. His levels have improvedand the doctor wants to try iui (I will post below his most recent semen analysis) I start letrozole tonight for the next five days and go in Tuesday for a mid cycle ultrasound and will have our first iui sometime shortly after. I’m also doing a trigger shot. I just am curious if anyone has had success with iui or if we even have a good chance of iui working with S/O levels
