They are coils that are put in your tubes to block them. I called to ask my doctor about getting my tubes tied & she mentioned Essure & IUD as well. I really don't think an IUD sounds like something I want & I want something more permanent then a pill or patch. Just wondered if anyone has tried the Essure method & if there was pain or it has worked. I do have an appointment to discuss the options in more detail with my doctor but wanted the opinion of someone who may have tried it.
