I really drove the agenda with CFA. I did three rounds of clomid, then asked for injectibles (granted), then did three rounds of that and asked for IVF. The Dr. said insurance would never approve it, but I said that I didn't care and asked him to submit the request anyways. It was approved. I think if you speak from a place of strength, you usually can get what you want. The CFA lab location is def more convenient than Rockville (and I do think they are a bit cheaper than SGF). Although, if they don't need to do a sperm wash, you may be able to do IUI at the K St. office. It also depends on if it's important to have a long term relationship with the same RE. Good luck OP!
