Ovarian pregnancy.

Ovarian ectopic pregnancy occurs very rarely; the reported incidence is only 1:7000-40,000 deliveries, despite various reports in recent years. We present four cases of primary ovarian pregnancy which were managed in the King Khalid University Hospital (KKUH) over a 5-year period representing a prevalence rate of 19.9 per 100,000 deliveries. All four cases complied with the four criteria of Spiegelberg. None of the patients were known to have used an intrauterine contraceptive device which had been suggested as the cause of ovarian pregnancies in several studies. Fertility after surgery in these cases was unaffected.
