Increasing incidence of ovarian pregnancy.

This paper presents the results of a review of seven ovarian pregnancies occurring during an 11 year period (1976-1986). The prevalence of the disease is higher than that expected either for the number of deliveries or for all ectopic pregnancies. The presence of etiological factors such as pelvic inflammatory disease, previous abdominal surgery, endometriosis or use of IUD, is considered. Four of these cases presented in actual users of IUD and one in an infertile woman previously diagnosed of endometriosis. The clinical pattern was similar to that recorded for tubal ectopic pregnancies. The role of IUDs and other risk factors in the apparent increase in the number of ectopic pregnancies detected is discussed. Measures to increase accuracy in the detection of early ovarian pregnancies are proposed.
