Müllerian anomaly

A congenital difference in the shape of the uterus.

Conditions

Müllerian anomalies arise from how the uterus formed before birth, and include septate, bicornuate, unicornuate and didelphys uteruses. Many cause no problems; some increase the risk of miscarriage or preterm birth. They are identified on 3D ultrasound or MRI and are managed by a specialist with experience in reproductive surgery.

Also known as: uterine anomaly, bicornuate uterus, unicornuate uterus, uterus didelphys
