Up until now, I thought follicles were eggs... So now, I'm a little disheartened. Now that I know they're not, does anyone know the minimum size a follicle must be for an egg to rupture? I've been reading a bit and it seems that a follicle has to be at least 18 mm to release. My doctor updated the info on our patient portal, and the measurements for my follicles were as follows: 23,124, 21,353, 14.194, 80.416 and 48. (Yes, the last two are correct... No typos. Hahaha!) So maybe if my research holds true, we'll have at least one good egg with 4 out of 5 follicles meeting the 18 mm minimum mark. Opinions?
