Primary ovarian pregnancy. Report of fifteen cases.

From June 1973 through November 1988, fifteen cases of ovarian pregnancy were admitted to the Shanghai First People's Hospital. All these cases met the four criteria for the diagnosis as listed by Spiegelberg. The incidence of ovarian pregnancy as compared to those of normal and ectopic pregnancy are 1:3 179 and 1:28.1, respectively, which are higher than foreign data reported. Ovarian pregnancy is quite similar to tubal pregnancy in clinical manifestations. Etiological analysis does not reveal any close relationship with inflammation of the female genital tract. However, application of IUD increases the risk of ovarian pregnancy. The principle of management is wedge resection of the diseased ovary.
