Four cases of ovarian pregnancy, occurring over a two-year period in the same hospital, are presented. Each case fulfills Spiegelberg's criteria. Each patient conceived with Cu-7 intrauterine contraceptive device (IUD) in situ. Review of the literature reveals an apparent increase in the frequency of ovarian pregnancy associated with IUD's. This aspect of the problem, as well as the management of this unusual type of ectopic pregnancy, is discussed. The data available do not justify a conclusion that ovarian pregnancies are caused by IUD's. Unless future studies demonstrate a cause-and-effect relationship, this may be merely an interesting coincidence. However, it seems that more than just coincidence is involved, even though the mechanism is unclear.
本文报告了在同一家医院两年内发生的4例卵巢妊娠病例。每例均符合斯皮格尔伯格标准。每位患者在宫内放置铜-7宫内节育器（IUD）的情况下受孕。文献回顾显示，与IUD相关的卵巢妊娠发生率明显增加。本文讨论了这一问题的这一方面以及这种不寻常类型的异位妊娠的处理。现有数据不足以得出卵巢妊娠是由IUD引起的结论。除非未来的研究证明存在因果关系，否则这可能仅仅是一个有趣的巧合。然而，即使机制尚不清楚，似乎不仅仅是巧合。
