What is the bicornuate uterus?

A bicornuate uterus is a uterine malformation characterized by the presence of two symmetrical uterine cavities, although the horns are not fully developed.

The cause of this type of uterus is an alteration in the fusion of the Müllerian ducts and a heart-shaped cleft is formed in the upper uterine area. Depending on whether the cleft reaches the internal and external cervical os, or only extends inside the uterus, there are two types: the complete bicornuate uterus and partial bicornuate uterus respectively.

Depending on the severity of this uterine anomaly, the risk of miscarriage and premature delivery may be increased.
