Side effects can include changes to the menstrual cycle, unwanted pregnancies, chronic pain, perforations of the uterus and , migration of the device to the abdominal or pelvic cavity and suspected allergic or .

A collective lawsuit against Bayer is set to be filed in France in September by a group of 400 women, a lawyer representing them told AFP, while a Facebook group called "Essure Problems" currently counts more than 33,000 members.
