Most uterine ruptures during pregnancy occur within a scarred uterus, rarely occurring in an unscarred uterus. Here, we report a very rare case of spontaneous rupture in an unscarred uterus at 11\u2009weeks of gestation of a twin pregnancy and its surgical repair. A 37\u2010year\u2010old nulliparous infertile woman became pregnant with twins after artificial insemination and gonadotropin therapy. She underwent emergency surgery at 11\u2009weeks of gestation due to an acute abdomen caused by massive hemoperitoneum. Upon laparotomy, one fetus with placenta was extruded into the abdominal cavity through a 3\u2010cm myometrium rupture on the left posterior wall of the uterus. After surgical repair of the rupture site, the remaining fetus was alive and was successfully delivered by cesarean section at 34\u2009weeks of gestation.<\/jats:p>","DOI":"10.1111\/jog.14396","type":"journal-article","created":{"date-parts":[[2020,7,9]],"date-time":"2020-07-09T02:44:35Z","timestamp":1594262675000},"page":"1911-1915","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Spontaneous
