Breast/Nipple Exposure to Sunlight

[kierkegaardian]

So there's those studies showing that sunning the male genitalia increase testosterone.

What's the data, or theory/hypothesis, about breasts and sun exposure?

Higher vitamin D in milk? More of a particular sex hormone (women, so progesterone?)?

My wife heard in a breast feeding group that sun exposure helped toughen the nipples for breast feeding, but I've never seen that in any research lit.

Anyway, benefits to breasts in the sun, know any?

Other than the same general-esque benefits there'd be for males (along with sunning the vulva and/or actual vagina inside) I'd imagine boobs out in the sun (at least) can't be a bad thing regardless. I mean if you're going to maximize the benefits of sun I'd imagine this couldn't be too bad a time to capitalize on the Vitamin D, A, the C, etc.
