Where did you get your IUI?

So long story short, I am currently on round 4 of Clomid, round 10 of TTC. My doctor put me on Clomid because they thought I *might* not be ovulating a mature egg each month, so if that was an issue, Clomid would likely fix it. An ultrasound showed I had two very tiny cysts on my right ovary, which I was told are common and not a reason for concern. I also have a retroverted uterus, which I was also told isnt an issue. I was getting positive ovulation tests before I ever started Clomid, and continued to each round, but haven’t ended up pregnant, so we decided to go ahead and get my husbands sperm tested. Turns out, his sperm is just poor overall. (Low count, mobility, etc). We have talked about it and we are going to of course try to get his sperm improved in whatever way the doctor recommends, but we would like to go ahead and proceed with an IUI, most likely with a sperm donor (because we assume my husbands sperm is not high quality enough).

My question is, where did you get your IUI? Did your Ob/GYN do it? Or did they refer you somewhere? Any info is appreciated!
