ABSTRACT Congenital uterine malformations are known to have a higher incidence of infertility, repeated first trimester spontaneous miscarriages, fetal intrauterine growth restriction, fetal malposition, preterm labor, retained placenta and increased cesarean section rate. The actual incidence of uterine malformation is unknown, since many women do not have any symptoms. They are estimated to occur in 0.4% (0.1-3%) of the general population and in 4% of infertile women, and in patients with repeated spontaneous miscarriages the figures fluctuate between 3 and 38%. The discrepancy among different publications stems from their use of different diagnostic techniques, heterogenous population samples and clinical diversity of Mullerian anomalies.
