You may not think about it much, but the science behind breasts is actually pretty interesting. Breasts are among the few organs that aren’t fully developed at birth, and we’re the only species on the planet whose breasts are permanently enlarged. Other mammals only have swollen mammary glands when they’re lactating. So, our boobs are pretty special.
AsapSCIENCE released a new video exploring some super interesting facts about boobs.
Here are some things it taught us:
About 50 percent of women have one breast that’s smaller than the other. More often than not, it’s the right one.
Your breast size can actually vary from week to week because of your hormone levels.
Take one guess what the most prevalent form of plastic surgery is.
Yep, breast augmentation.
82 percent of women and 53 percent of men report the stimulation of nipples enhances sexual arousal.
