Abstract: The incidence of the uterine malformations is estimated to be 3-5% in the general population. Abnormal fusion of the mesonephric duct (mullarian duct) during embryonic life results in a variety of congenital uterine malformations like septate uterus, unicornuate uterus and bicornuate uterus. In the present case, the patient had a history of 3 miscarriages. She was 27 years old, married for 4 years. Due to bad obstetric history after thorough investigations, the cause for it is diagnosed as having unicornate uterus.
