A new study finds long-acting reversible contraception is superior to the pill, patch, or ring, when it comes to eliminating unintended pregnancies.
Researchers at Washington University School of Medicine analyzed the birth control practices of nearly 7500 women. They found the contraceptive failure rate among those using pills, a transdermal patch, or a vaginal ring was about 20 times higher than those using long-acting reversible contraception, like an intrauterine device or an implant.
Researchers say long-acting reversible contraception may help decrease the more than 3 million unintended pregnancies every year in the United States.
IUDs can last five to ten years. Hormonal implants in the upper arm can last for three years.
These methods may have the lowest failure rate, but they're not very popular.
Many women can't afford the up front costs, which can be more than $500.
