Does your RE have some kind of rule against doing an IUI when there are too many follies due to risk of multiples?
I'm not sure I understand the reasoning why your RE would cancel if you have more than 4 follies... I just completed my first cycle of Gonal-F, and my follies changed sizes so much, it wasn't until yesterday (cd11) that we figured out how many "good" ones I have that will rupture - which by the way is 5. I had my iui done today and another one set for tomorrow at noon. There is a possibility that some of your follies won't make it to the size needed for it to rupture. In fact, my dose on Gonal F was low at 300iu for 2 days, 150 for the next couple of days, then 225iu for two nights in a row. I have a bunch of follies, but like I said, only 5 are ready enough to rupture... I hope this helps a little :-) Good luck to you!
Before I started injectibles, my RE told me that he would not do an IUI if there were too many follies - I thought he meant 7+. Today when I went in, he said that he would cancel the IUI if there were more than 4 and 4 is borderline. I was surprised - I was hoping for 5-6 good follies. I haven't gotten pg at all, so I wanted lots of good targets. I have 6 follies 9-11 mm. He lowered my dosage to see if some would grow more than others. I was also surprised by how quickly they grew - I'm only on CD7. How big were your follies when you triggered? Did some follies grow "big" in the beginning but then not mature?
I hope only four of them continue to grow at a higher rate so you only have four mature ones by the time you're ready for trigger. My RE is the same way...he prefers 3-4 follicles for an injectable/IUI cycle, but no more due to the risk of high-order multiples. Best of luck!
docsaf: On CD7 I had a bunch of follies in the 9-11 range (I'm talking like 10!!), but 5 of them made it to trigger. Yesterday they were ranging from 18-23, and they grow more since I had my trigger and also O time... I hope this helps a little :-) Good Luck!!! If you have any questions, feel free to ask!!
