Case Discussion

Uterine malformations are found in 0.5-5 % of the general population, in 0.1-3 % of fertile women, in 3% of infertile women and in 5-10% of women who have recurrent miscarriages.

These uterine anomalies are the result of a defective fusion of the Müllerian duct in the midline or a missed or incomplete resorption of the septum that results from their merger. According to the American Fertility Society, there are seven classes of uterine malformations:

  1. bilateral Mullerian agenesis or hypoplasia
  2. uterus unicornis
  3. didelfo uterus, with two horns and two necks
  4. bicornuate uterus unicolle
  5. uterine septum
  6. arcuate uterus
  7. anomalies associated with exposure to diethylstilbestrol
