Jennie Rothenberg-Gritz: Here's something strange I've noticed in both my pregnancies: At a certain point in the second trimester, I stop having to shave my legs.

James Hamblin: This could sound like pandering, but shaving legs is just the American feminine ideal driven by razor companies and a few early twentieth-century ad campaigns in Harper's and Ladies' Home Journal. No one has to do it, especially not pregnant women, who should be able to do whatever they please -- not just have priority parking spots, but actually go around with hairy legs and otherwise disregard cultural norms. Showing up late, yelling, spitting, all of that.

Well, maybe so, but what I mean is that my leg hair stopped growing.

Oh, that's interesting. That would be because of hormones. Your blood is carrying more estrogen, progesterone, and more testosterone right now than it usually does. Since you're in your third trimester, you probably have, for one, about twice the amount of free testosterone in your blood as you normally do.

Wouldn't testosterone make a woman more hairy, not less?
