Missy - I have had 5 IUI's - For the 1st one I was on 100mg of Clomid and had 2 follicles - got pg but had m/c at 5wks. Round 2 - also 100mg with 2 follicles, Rounds 3 & 4 - 150mg - with 2 mature follicles and 2-3 smaller ones. Round 4 I also had daily Follistim injections. Round 5 - no Clomid at all.

I think the # of follicles depends on the dosage and your own body's reaction to the med. If Clomid alone doesn't produce enough mature follicles for an IUI they may up your dose or also include the use of injectibiles.
