Generalized questions to figure out a baseline for your hormones and body composition. My guess is they then match that up to some sort of corresponding chart for female hormones and body composition and try to find a match.
What information? Your height, weight, body hair status? As for the corn thing…I mean, I’m not even sure what bearing it has on the results. But thinking back to being a kid, we had corn a few times a month, maybe.
I mean.... Did you not do laundry growing up? I've washed my mother's bras doing chores, so while I don't have the size exact or committed to memory, I can at least say "C or above" like the question asks. Lol.
