Several developmental abnormalities of the uterus can be discovered during an infertility evaluation. A unicornuate uterus, septum or septate uterus, and a bicornuate uterus are among the numerous structural anomalies. These problems arise when the uterus is being formed. A unicornuate uterus is when only one side of the uterus is formed normally. A bicornuate uterus is a uterus that has two sides of the uterus that are attached at the cervix but not at the top of the uterus. A septum is a normal shaped uterus that has a dividing membrane on the inside of the uterus. Hysteroscopy is useful in evaluating and treating these abnormalities. Other effective means of evaluating the uterus include saline contrast ultrasound and hysterosalpingogram (HSG). IHR has extensive experience treating for structural abnormalities of the uterus.
