The Anatomical Structure Of A Double Uterus Or Uterus Didelphys

Description

Paired uterine horns occupy the midline pelvis, separated by a deep fundal cleft and continuing inferiorly as two discrete endometrial cavities. Each hemiuterus narrows into its own cervix, positioned side by side at the superior vagina, with the bladder lying anterior and the rectum posterior in standard anatomical position. The animation sequentially isolates the two myometrial bodies, then traces each cervical canal toward the vaginal apex to clarify the duplicated outflow tracts. Spatial symmetry is the point. Uterus didelphys results from complete failure of Müllerian duct fusion, and it matters because the external contour can look deceptively normal on limited imaging while the internal duplication drives clinical decisions. Recurrent pregnancy loss, malpresentation, preterm birth, and obstructed hemivagina in the related OHVIRA spectrum are common reasons these patients present, and management differs from a septate uterus where hysteroscopic septum resection may be appropriate. By moving through the cavities and cervices in sequence, the animation makes the distinction between two separate uteri and a single uterus with an internal septum hard to miss, which is exactly what you need when teaching classification (ASRM, ESHRE-ESGE) or counseling around obstetric risk. Use this animation in reproductive anatomy blocks, embryology lectures on paramesonephric duct development, and radiology teaching files paired with pelvic MRI (T2 sagittal and axial oblique) or 3D ultrasound correlates. It also fits OB-GYN clinic education, preoperative planning discussions, and publisher figures on congenital uterine anomalies and infertility workups.
