We report a case of ovarian pregnancy that supports a blastocyst migration mechanism. An infertile woman became pregnant after a single blastocyst transfer following <jats:italic>in vitro<\/jats:italic> fertilization during a fresh non\u2010donor cycle. Transvaginal ultrasound revealed a gestational sac\u2010like 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.<\/jats:p>","DOI":"10.1111\/jog.12790","type":"journal-article","created":{"date-parts":[[2015,7,30]],"date-time":"2015-07-30T07:37:27Z","timestamp":1438241847000},"page":"1823-1825","source":"Crossref","is-referenced-by-count":6,"title":["Ovarian pregnancy associated with a fresh blastocyst transfer following <i>in vitro<\/i> fertilization"],"prefix":"10.1111","volume":"41","author":[{"given":"Hiroshi","family":"Ishikawa","sequence":"first","affiliation":[{"name":"Department of Reproductive Medicine, Graduate School of Medicine Chiba University  Chiba Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michio","family":"Sanada","sequence":"additional","affiliation":[{"name":"Department of Reproductive Medicine, Graduate School of Medicine Chiba University  Chiba Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Makio","family":"Shozu","sequence":"additional","affiliation":[{"name":"Department of Reproductive Medicine, Graduate School of Medicine Chiba University  Chiba Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,7,30]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmig.2009.01.002"},{"key":"e_1_2_5_3_1","first-page":"OD06","article-title":"Ovarian pregnancy: Uncommon mode of presentation","volume":"8","author":"Jena SK","year":"2014","journal-title":"J Clin Diagn Res"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1447-0756.2012.01963.x"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejogrb.2014.07.049"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2014-006447"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1093\/humrep\/13.12.3285"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fertnstert.2011.02.015"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fertnstert.2013.10.002"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fertnstert.2014.11.023"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.4293\/108680812X13462882736385"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijgo.2011.02.013"}],"container-title":["Journal of Obstetrics and Gynaecology Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fjog.12790","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fjog.12790","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jog.12790","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,2]],"date-time":"2023-10-02T05:32:28Z","timestamp":1696224748000},"score":1,"resource":{"primary":{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/10.1111\/jog.12790"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,7,30]]},"references-count":11,"journal-issue":{"issue":"11","published-print":{"date-parts":[[2015,11]]}},"alternative-id":["10.1111\/jog.12790"],"URL":"https:\/\/doi.org\/10.1111\/jog.12790","archive":["Portico"],"relation":{},"ISSN":["1341-8076","1447-0756"],"issn-type":[{"value":"1341-8076","type":"print"},{"value":"1447-0756","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,7,30]]}}}
