A bicornuate uterus results from abnormal development of the paramesonephric ducts. There is a partial failure of fusion of the ducts, resulting in a uterus divided into two horns. A bicornuate uterus means your uterus is shaped like a heart. A typical uterus is shaped like an upside-down pear. The wide, round part of the pear resembles the top portion of the uterus. If your uterus is bicornuate , the top of your uterus dips down at the middle, making it look like a heart. The bicornuate uterus, commonly referred to as "uterus bicornis," is a congenital uterine anomaly characterized by a heart-shaped uterus with two conjoined cavities instead of a single, unified cavity. A bicornuate uterus is a congenital uterine anomaly characterized by a uterus that has two distinct horns instead of a single, pear-shaped cavity. This condition arises during fetal development when the Müllerian ducts, which form the female reproductive tract, fail to fuse completely.
