Anatomic gynecologic anomalies occur when there is failure of normal embryonic ductal development. These include conditions such as congenital absence of vagina, lateral fusion defect and vertical fusion defect of the Mullerian duct. The treatment of Mullerian anomalies should be based on accurate diagnosis and comprehension of the developmental process. Congenital uterine anomalies occur in approximately 1 in 2000 newborn female infants. It is also important to provide adequate consultation and explanation to all family members with regard to the aim of treatment, possible complications that may ensue, and changes in future fertility potential.
