Double Uterus Or Uterus Didelphys

Description

Uterus didelphys appears as paired uterine bodies positioned side by side within the pelvis, separated by a deep midline cleft that reflects complete nonfusion of the paramesonephric (Müllerian) ducts. Each hemiuterus contains its own endometrial cavity, with separate myometrial walls and a distinct fundus oriented superiorly. Inferiorly, two cervices descend toward the upper vagina, typically lying parallel with a narrow band of intervening tissue, while the adnexal regions (uterine tubes and ovaries) would be expected laterally if included in frame. Two cervices are present. This configuration matters because it reframes “uterine anomaly” from a single distorted cavity to two independent reproductive tracts, which directly affects obstetric counseling and procedural planning. Uterus didelphys is associated with malpresentation, preterm birth, and recurrent pregnancy loss, and it can complicate cervical assessment because each cervix may dilate or efface differently; the fixed view that keeps both uterine cavities and cervices in the same plane helps clarify why imaging reports must specify laterality and which cavity contains a gestation. In practice, you also look beyond the pelvis: Müllerian malformations correlate with ipsilateral renal anomalies (including unilateral renal agenesis), so a pelvic finding often triggers urinary tract evaluation. Use this illustration in embryology and reproductive anatomy teaching to contrast Müllerian fusion defects (didelphys vs bicornuate vs septate uterus), and in obstetrics and gynecology materials discussing infertility workup, pregnancy risk stratification, and preoperative counseling before hysteroscopy, laparoscopy, or cesarean delivery in anomalous uteri. It also supports radiology lectures on correlating pelvic ultrasound and MRI descriptions with real spatial anatomy. Anatomical accuracy verified by SciePro's Medical Advisory Board.
