Nikki, my FS never suggested IUI, maybe because my DF's sperm count is almost non existant and he needed to pluck them out with a needle after a versectomy reversal didn't work ie the sperm weren't coming out like they should be (I ovulate on day 14 of every cycle).
We did one round of IVF in My last year and fell pg straight away. I only lost my little boy because I had a pretty big fibroid that went ferral with the IVF drugs and the pg hormones.
Good luck hun, if you're not too sure of what to do, please get a second opinion.
