We present a case of twin pregnancy in a uterus didelphys and objectively analyze the synchrony of bilateral uterine contractions. A 32\u2010year\u2010old woman, with a history of vaginal septal resection during her previous vaginal delivery, became pregnant with twins in a uterus didelphys in which each uterine horn had one fetus. At 37 weeks and 6 days, the first baby was delivered vaginally. The second baby was delivered by cesarean section due to recurrent late decelerations. Operative findings confirmed the didelphys uterus. We retrospectively reviewed the timing of contractions of both uteruses. The timing was determined by visual analysis as synchronous if both uteruses contracted within 5\u2009s. Otherwise, contractions were considered solitary. Both uterine horns contracted independently in 90% of the incidence throughout labor and delivery. From this rare case of an \u2018experiment by nature\u2019, we speculated that the myometrium must be histologically connected in order to synchronize uterine contractions.<\/jats:p>","DOI":"10.1111\/jog.12219","type":"journal-article","created":{"date-parts":[[2013,11,19]],"date-time":"2013-11-19T04:56:54Z","timestamp":1384837014000},"page":"836-839","source":"Crossref","is-referenced-by-count":18,"title":["Independent uterine contractions in simultaneous twin pregnancy in each horn of the uterus didelphys"],"prefix":"10.1111","volume":"40","author":[{"given":"Yohei","family":"Maki","sequence":"first","affiliation":[{"name":"Obstetrics and Gynecology University of Miyazaki  Miyazaki Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seishi","family":"Furukawa","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynecology University of Miyazaki  Miyazaki Japan"},{"name":"Obstetrics and Gynecology Miyazaki Medical College  Miyazaki Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshi","family":"Sameshima","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynecology University of Miyazaki  Miyazaki Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tsuyomu","family":"Ikenoue","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynecology University of Miyazaki  Miyazaki Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,11,18]]},"reference":[{"key":"e_1_2_4_2_1","first-page":"115","article-title":"Double uterus with a pregnancy in each half","volume":"61","author":"Nhan VQ","year":"1983","journal-title":"Obstet Gynecol"},{"key":"e_1_2_4_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.1953.tb14065.x"},{"key":"e_1_2_4_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(54)90209-4"},{"key":"e_1_2_4_5_1","doi-asserted-by":"crossref","first-page":"663","DOI":"10.1016\/0002-9378(56)90394-5","article-title":"Uterus didelphys with double pregnancy","volume":"72","author":"Clarke PE","year":"1956","journal-title":"Am J Obstet Gynecol"},{"key":"e_1_2_4_6_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.1.5120.486-a"},{"key":"e_1_2_4_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(73)90907-1"},{"key":"e_1_2_4_8_1","first-page":"427","article-title":"Uterine anomalies.
