Müllerian duct anomaly classification

The Müllerian duct anomaly classification is a seven-class system that can be used to describe a number of embryonic Müllerian duct anomalies:

• class I: uterine agenesis/uterine hypoplasia
  • a: vaginal (uterus: normal/variety of abnormal forms)
  • b: cervical
  • c: fundal
  • d: tubal
  • e: combined
• class II: unicornuate uterus/unicornis unicollis, ~15% (range 6-25%)
  • a: communicating contralateral rudimentary horn contains endometrium
  • b: non-communicating contralateral rudimentary horn contains endometrium
  • c: contralateral horn has no endometrial cavity
  • d: no horn
• class III: uterus didelphys, ~7.5% (range 5-11%)
• class IV: bicornuate uterus: 2nd most common type ~25% (range 10-39%)
  • a: complete division, all the way down to the external os (bicornuate bicollis)
  • b: partial division, not extending to the internal os (bicornuate unicollis)
• class V: septate uterus: commonest anomaly, ~45% (range 34-55%)
  • a: complete division, all the way down to the internal or external os
  • b: incomplete division, involving the endometrial cavity but not the cervix
• class VI: arcuate uterus, ~7%
• class VII: in utero diethylstilbestrol (DES) exposure (T-shaped uterus)
