“…Adnexectomies instead of conservative surgery were performed in 30%, 6%, 41% and 78% respectively. Not surprisingly women in shock had more adnexectomies (P<0.0001) In 2 women a hysterectomy was performed (1.8%), one with a gestation of 44 weeks with the placenta involving the uterus (37), and one in a 45 years old lady (38). Follow-up after surgery was uneventful in all except in 1 woman in whom medical treatment was given because an HCG of 2134 IU/ml suggested residual trophoblastic tissue (39).…”

Objective Ovarian pregnancy is a rare but well-known pathology. However, pathophysiology, diagnosis and treatment are not clearly established. Data sources. All case reports published in Pubmed from Nov 2011 till Nov 2022. Study eligibility criteria. A systematic review and 2 case reports of ovarian pregnancy Study appraisal and synthesis methods. Not applicable Results Ovarian pregnancies occur in 8% of women without or blocked oviducts and in 23% on the other side than the corpus luteum and the symptoms of ovarian pregnancies are not specific. Therefore ovarian pregnancy has to be suspected in all women with abdominal bleeding. As for extrauterine pregnancies, the presence of an intrauterine pregnancy does not rule out an ovarian pregnancy. Surgical excision is the preferred treatment. Important is that in women with both an intra-uterine and an ovarian pregnancy, care should be taken not to damage the corpus luteum. Conclusions Ovarian pregnancies can occur in women with blocked tubes, on the other side of the corpus luteum, in the presence of an intrauterine pregnancy, and even when pregnancy tests or tranvaginal ultrasonography are negative. The diagnosis being difficult to exclude, a laparoscopy is indicated in all women with intra-abdominal bleeding, keeping in mind that an intra-uterine pregnancy cannot be exluded and that a corpus luteum need to be respected.

“…Ovarian pregnancy is a rare form of ectopic pregnancy, accounting for 0.5–3% of all ectopic pregnancies . Although the exact cause of ovarian pregnancy is unknown, two distinct mechanisms for establishing ectopic implantation in the ovary are possible: direct fertilization inside the ovary and ectopic implantation of a fertilized embryo floating out from the fimbria . The latter is associated with the retrograde migration of a transferred embryo from the endometrial cavity to the ovarian surface.…”

“…1 Although the exact cause of ovarian pregnancy is unknown, two distinct mechanisms for establishing ectopic implantation in the ovary are possible: direct fertilization inside the ovary and ectopic implantation of a fertilized embryo floating out from the fimbria. 2 The latter is associated with the retrograde migration of a transferred embryo from the endometrial cavity to the ovarian surface. The migration seems to occur during embryo cleavage, but not after the blastocyst is fully matured, because a blastocyst can quickly implant once it reaches the endometrial cavity.…”

Ovarian pregnancy associated with a fresh blastocyst transfer following in vitro fertilization

Ovarian pregnancy is a rare subtype of ectopic pregnancy, and its mechanisms have not been clarified. We report a case of ovarian pregnancy that supports a blastocyst migration mechanism. An infertile woman became pregnant after a single blastocyst transfer following in vitro fertilization during a fresh non-donor cycle. Transvaginal ultrasound revealed a gestational sac-like structure containing an active fetus that was located adjacent to the corpus luteum of the right ovary. Laparoscopy identified a red, swollen implantation site in the ovary, which was completely removed by wedge resection without damaging the remaining parenchyma. This case demonstrated that a fresh blastocyst transferred into the endometrial cavity migrated through the fallopian tube, implanted on an ovarian surface, and formed an ovarian pregnancy.

Ovarian pregnancy is a rare but well-known pathology. However, pathophysiology, diagnosis and treatment are not established. Therefore, all case reports on ovarian pregnancy published in PubMed from November 2011 till November 2022 were reviewed and two case reports were added. In these 84 case reports, 8% of ovarian pregnancies occurred in women without or with blocked oviducts and 23% were localised on the other side than the corpus luteum. Since symptoms are not specific, ovarian pregnancy has to be suspected in all women with abdominal bleeding. Surgical excision is the preferred treatment. However, since an associated intra-uterine pregnancy cannot be excluded, care should be taken not to interrupt this intra-uterine pregnancy with the uterine cannula or by damaging the corpus luteum. In conclusion, in women with abdominal bleeding, an ovarian pregnancy cannot be excluded, even in women with a negative pregnancy test or an empty uterus on transvaginal ultrasonography. Therefore, a laparoscopy is indicated but the surgeon should realise that an associated intra-uterine pregnancy also cannot be excluded and that therefore care should be taken not to interrupt this intra-uterine pregnancy by the uterine cannula or by damaging the corpus luteum.
