Just for the record to those doing jabs and gg to do ivf, I didnt know what E2 is good but i thought the higher the better, like over 10k and I think I am right.. Anyway, my E2 was abt 7800, retrieved 9 and 4 matured. Hope this is helpful. Also I thought I could have more to mature as it seems the follicles met the criteria before hcg but I think best to have 18mm and above. Sharing this as I just went through this.
