The boredom and restlessness of the 2ww have begun. The solution: IFROCGD (Infertility Related Obsessive Compulsive Googling Disorder). Today's search: E2 levels as they relate to follicle size.

(Yes, I'm still obsessed with the size of my follicles.)

I triggered 36 hours after my follicles were at the following sizes (this is CD9) (does not include follicles under 10mm):
  1. 10.83
  2. 11.35
  3. 11.67
  4. 12.53
  5. 14.01
  6. 14.14
  7. 14.48
  8. 14.66
  9. 15.16
  10. 15.29
  11. 15.58
  12. 15.78
  13. 15.93
(Phew, that's a lot!)

My E2 level on that day (CD9) was 599 pg/ml.

What I wanted to know: Is that E2 level too low? Because it seems kind of low, for that many follicles.

What I learned: Apparently each mature follicle should contribute 150-200 pg/ml towards the overall level, but all follicles contribute, not just the mature ones, so you can't just divide your total by 150 or 200 to know how many mature follicles you have. So, I'm not sure if it was low or not. But I did read that E2 levels over 1000 are related to a higher incidence of HOM ("High Order Multiples": learned that today, too).

I also learned that follicles grow from 1 to 2mm per 24 hours, and that follicles are considered mature at varying sizes, but 18mm-20mm seems to be about standard. My two largest follicles (15.78 and 15.93) might have just made 18 by the time I triggered 36 hours later. Of course I injected two more shots of gonal-f during that 36 hours, so hopefully they were on the high side of the estimate.

I've also been thinking a lot about IUI/IVF success statistics and what they really mean (to me). Haven't googled it yet. But then, I have 11 more days of the 2ww to go, so I've got plenty of time!

(Somebody stop me.)

  1. I didn't get my E2 checked right before I triggered, but my RE won't tell me to give the trigger until the follies are around 18mm. That being said, he also doesn't have me continue follistim with/after the trigger, so you are probably fine!! I've been trying so hard to stay away from google this time ;-)
