Ovarian ectopic pregnancy in association with a copper-7 intrauterine device in situ.

A case is reported of a primary ovarian pregnancy in a patient with a Cu-7 intrauterine device. A brief review of the literature on this subject is exposed. As the action of intrauterine devices on the ovulatory mechanism and tubal transport of the ovum is still unknown, further studies should be carried out to explain this association.
