title: The intrauterine device and ovarian pregnancy.
abstract: Within a 1-year period, three patients presenting to the University of Chicago, Chicago Lying-In Hospital with a complaint of lower abdominal pain were diagnosed at laparotomy to have ovarian pregnancies according to the criteria of Spiegelberg. All of the patients were at the time using the Copper-7 intrauterine device for contraception. There are now 50 known cases of ovarian pregnancies in patients using the intrauterine device (IUD). The characteristics of these patients do not differ markedly from those previously reported in studies on tubal pregnancies, with and without the IUD, but the presentation of patients tends to be more variable than in tubal pregnancies. The increasing incidence noted here, in a population already known to be particularly prone to pelvic inflammatory disease and therefore ectopic pregnancies in general, lends further credence to a questioning of the desirability of the IUD in such a population.
