Hi, I am an egg freezer. I have 4 follicles being tracked (26, 22, 19.5 and 18...... there are also some smaller ones). Triggering tonight. My question is: do follicles become over mature? Meaning...is the follicle at size 26 likely to be fertilizable, or is it too big/over the hill? I m on antagonist protocol (femara, menopur, ganirelix).
