Risks associated with the Essure system include:

  • Tubal blockage occurring on only one side
  • Perforation of the uterus or fallopian tubes
  • Pelvic pain
  • Infection

You may not be able to have further pelvic electrosurgical procedures, such as some types of endometrial ablation, after having the Essure system implanted.

The Essure system doesn't offer protection from sexually transmitted infections (STIs).

In the first year after implantation of the Essure system, fewer than 1 out of 100 women will get pregnant. The risk of unintended pregnancy is likely highest during the first three months after the placement of the Essure system.

If you do conceive after having the Essure system inserted, there's a higher chance that the pregnancy will be ectopic — when fertilization happens outside the uterus, usually in a fallopian tube.
