The Center for Disease Control and Prevention has announced that the risk of pregnancy for women who have been sterilized is greater than previously thought. The CDC has discovered that women who were sterilized before the age of 28 are more likely to become pregnant than women who had the operation at later age. The CDC also found that the bipolar coagulation, a procedure chosen by women because it is less invasive, where a doctor makes a tiny incision in the woman’s abdomen and plugs her fallopian tubes by either burning them with an electric current or applying a silicon rubber band to the tips, has a higher percentage of unexpected pregnancies. The conventional procedure, performed right after a woman gives birth commonly known as “having your tubes tied,” is the procedure with the lowest rate of fertilization. Female Sterilization is the most common form of birth control for women in the U.S. Women who have been sterilized or plan to, should speak to their doctors about their individual cases what factors may increase their risk of unexpected pregnancy.
