title: Tubal ectopic pregnancy with contralateral corpus luteum: a report of five cases.
abstract: In a series of 92 ectopic tubal pregnancies studied pathologically, 5 cases were associated with contralateral corpus luteum. Berlind's theory of ovum transmigration in the etiology of tubal pregnancy is revived and brought into line with Iffy's delayed ovulation-reflux hypothesis. The need for further delineation of etiologic factors is stressed, especially with a view to prevention.
