Too mature to fertilize?

JMay

If I understand correctly, an 18mm follie is considered "mature" enough to fertilize.  But how mature (big) is "too mature"?  If I don't O until Thursday, my big follie will be 29-32mms, which seems gigantic.  At that point, my only hope would be that the 14mm got to 18mms, right?

In most cases, the eggs release from the follies before they are too mature.  Hang in there sweetie....I know this is pure torture.

Honesly, according to my RE, that 26 one is probably too big for someone taking femara.  They triggered a 26 for me, and told me later that it was already likely too big.  The next time (last month's IUI), they triggered me with a 24 and thought that was good but borderline. Now, if it's too big to fertilize or if it's just less likely, I don't know. And I'm certainly no MD, just relaying what they told me, for me, and if you aren't triggering, I'm not sure how that changes things.

You still have time for your 14s to get bigger, though. I think they said 18 is mature for femara, so in 2 days you'd likely be there with 2 nice follies.

Again, I don't know, I'm not a doc, but the 26 does sound big, for femara, for my personal circumstances according to my RE, but it could totally be different for you.

Hang in there!

My 2 big follicles for the IVF cycle were between 22-23mm and the rest were all around 15ish.  My doc said anything over 15mm is mature enough to fertilize.  Not sure about super big ones but I wanted to give you confidence that your smaller ones will be in perfect shape.  Thinking of you!

Thank you ladies!  Your comments give me peace of mind.  I'm actually kind of pulling for the smaller ones.  RE asked me to do OPKs just for curiosity, to see when I get a + since this is my first cycle with him.  Yesterday and today are both negative, so by tomorrow the 14 should be ok... I think... fingers crossed!
