Abstract

A series of 20 cases of primary ovarian pregnancy that were diagnosed and treated in one institution is reported. The prevalence rate of 1:3600 deliveries seems to be increasing in past years and comprises 3.3% of all extrauterine pregnancies. Clinical presentation, possible pathogenesis, diagnostic steps, preferred management, and future fertility are detailed. Inasmuch as all our 18 fertile patients used an intrauterine contraceptive device before the operation, special emphasis is made on the controversial relationship between use of intrauterine contraceptive devices and ovarian pregnancy.

A series of 20 cases of primary ovarian pregnancy that were diagnosed and treated in one institution is reported. The prevalence rate of 1:3600 deliveries seems to be increasing in past years and comprises 3.3% of all extrauterine pregnancies. Clinical presentation, possible pathogenesis, diagnostic steps, preferred management, and future fertility are detailed. Inasmuch as all our 18 fertile patients used an intrauterine contraceptive device before the operation, special emphasis is made on the controversial relationship between use of intrauterine contraceptive devices and ovarian pregnancy. A previous study indicated that IUDs had no effect on ovarian pregnancies; however, 2 studies demonstrated a or= 25% and 68% concurrent use of an IUD and ovarian pregnancy. In this series, 90% of the women had an IUD in situ when ovarian pregnancy was diagnosed; the average duration of use was 2 years with a range of 6-54 months. The remaining 2 women were infertile before and remained so after surgery. This demonstrates that all of the fertile women employed an IUD at the occurrence of ovarian pregnancy. Therefore, this observation strongly indicates that the IUD is involved in the pathophysiology of ovarian pregnancy. Ovarian endometriosis does not seem to be an important causative factor, inasmuch as we found no evidence of the disease in any of our cases. (author's modified).
