So we already knew IUDs were stealthily awesome and may protect us against cervical cancer, but a new study in the New England Journal of Medicine claims that the risk of accidental pregnancy in women who use pills, patches or rings are actually a whopping 20% greater than women who use IUDs, which is kind of a crazy statistic considering only 1 out of 20 women stateside use them.


However, they're catching on internationally; as of 2011, one third of Chinese women, 20% of Scandanavian women and Vietnamese and Egyptian women (both 35%) use "long acting" contraceptive device. The only areas in which IUDs are less popular than the Americas is sub-Saharan Africa.
