A new study from England found that women using the shot did have a higher risk of broken bones compared to women using other types of birth control—but that was the case before they ever used the shot.
Women who eventually used the shot were 30% more likely to have a broken bone before starting the method compared to women who went on to use a different birth control method. After starting the shot, women were no more likely to have a broken bone than before.
