Laparoscopic picture of a bicornuate uterus
A bicornuate uterus is one of several congenital uterine anomalies. It is a defect caused during early development that occurs prior to birth. It would not be discovered until sometime in adult life - or may never be discovered at all if there are no reproductive problems.

A bicornuate uterus should not cause infertility, but is associated with increased risks for miscarriage and preterm birth. It can be diagnosed using high quality 3D ultrasound and can be suspected from the results of a hysterosalpingogram, HSG (dye test).
