NEJM study: IUDs, implants prevent more unwanted pregnancies

A massive new study has determined that contraceptive implants and intrauterine devices (IUDs) help prevent unwanted pregnancies a lot more than the pill, patch or other ring-type birth control products, MedPage Today reports. Researchers at the Washington University in St. Louis conducted a trial involving almost 7,500 women for three years. They found that unwanted pregnancies hit an average 4.55 per 100 person-years in patients that used pills, patches or vaginal rings. But patients who used IUDs or implants faced unwanted pregnancy rates of .27 per 100 person-years, according to the New England Journal of Medicine study. Story
