Follicle size-too big?

blsav23 · January 2015

I had IUI #4 yesterday & of course, I'm already beginning the torture of the TWW. I got to thinking about my follicle size. I had 3 at the time of IUI. When I went in for a scan the day before IUI they were 27, 21, & 17mm. I have read some articles saying the 27 may be "too ripe".
Have any of you heard this before? But I'd still have two goods ones, the 21 & 17, right?

Yes-I triggered immediately following my scan; so about 18 hours before IUI

Hmm, the 27mm might have been "too ripe," as you said but the other 2 were in a good range! Good luck!

I was super excited about the 27 but then I started thinking it seems pretty large. Here's hoping those other two weren't old & crusty also

Thanks!!

For Clomid, I believe it's typical to trigger after 20mm. So your smaller two should be in the perfect range.

Thanks so much! I stress myself to death & need to chill

I was on femara this round but am assuming they want the same size as clomid?

@blsav23 Yes, they count "mature" at the same gauge (18-20, usually) for all oral meds cycles. (The "mature" gauge is different for natural cycles and injects cycles, I learned.)

Interesting. Do you know what they consider mature for natural & inject cycles? I've also read that they like to see them grow more slowly rather than super huge, super fast.

@BlueFairy5 thanks for the clairification! I had my first inject cycle and am currently in the two week window. We had two 16.9 follicles at my last ultrasound, and they had me trigger the following evening, and I was worried they were too small!!! No one ever explained to me that peak size is different for different meds! I've found that if I don't ask questions, my RE office just doesn't explain ANYTHING!

Different REs have different opinions (I seem to remember @rainbowbridge14's RE considers them mature on a medicated cycle at 16? Unless my brain made that up?) but standard seems to be:

unmedicated 20-24mm
oral meds: 18-24mm
FSH (Follistim, Gonal-F) only: 17mm minimum (not sure if they set a cap around 24?)
FSH + LH (Menopur? I think? I should know this since I'll be on it): 16mm minimum

And keep in mind that after you trigger, they've still got about 36 hours to grow before they release.

Thanks!! What great info, which has proved to be beneficial to many!
