Want to reduce your chances of getting knocked up before your ready for a baby? According to a new study in the New England Journal of Medicine, the intrauterine device (IUD) is now considered "superior" to other forms of birth control due to its higher success rate at preventing unwanted pregnancies.

The results were striking: women using pills, patches, or rings "had a risk of contraceptive failure that was 20 times as high as the risk" among those using IUDs." And, much as the authors had hypothesized, women younger than 21 who chose to use a pill, patch, or ring—rather than an IUD—were twice as likely to become accidentally pregnant than older women. ... The study’s conclusion runs a single, unequivocal sentence: the effectiveness of IUDs is simply superior to other contraceptives. "If there were a drug for cancer, heart disease, or diabetes that was 20 times more effective," said [senior author Jeffrey Peipert], "we would recommend it first.
And more women around the world seem to be hopping on board the IUD trend. According to this 2011 study, one third of Chinese women, 20% of Scandanavian women and Vietnamese and Egyptian women (both 35%) have chosen to use this "long acting" contraceptive device.
