I have my first iui on Thursday. I have 5 mature follicles and my lining is 11.6, so everything looks good. We have slight morph issues so Im happy to have lots of follicles. But oh my, is that too many? I think my RE is a tad concerned, but she said we will move forward.
Our Journey from two to three!
3 IUI's, 2 IVF's, decided to move to foster/adopt.
12/24/2009 Baby C born, 2/1/2010 placed with us,
5/17/2011 Adoption final- we are finally a forever family!

Re: IUI success stories!
My second IUI was successful with only one follie, but we didn't have any male fertility problems, it was all unexplained. I wouldn't be worried about have 5, I think it just gives you more of a chance of success.
