Unicornuate Uterus

Definition - What does Unicornuate Uterus mean?

Unicornate uterus is a condition where the uterus may be misshaped and smaller then normal with only one functioning fallopian tube. A unicornate uterus may impact a woman’s ability to become pregnant. If pregnant, a unicornate uterus may lead to complications including heightened risk of preterm labor, miscarriage, recurrent pregnancy loss, ectopic pregnancy, or cesarean section.

FertilitySmarts explains Unicornuate Uterus

Unicornate uterus is a congenital disorder, meaning a woman is born with the abnormality. During development as a fetus, the two tubes that fuse together to create the uterus fail to form correctly, leaving the woman with what is essentially half of a uterus. The remaining half, along with one fallopian tube, may be nonexistent, or may be small and detached, called a hemi-uterus.

Unicornate uterus is typically undetected until fertility issues arise. However, if a hemi-uterus is present it may cause pain earlier in life, leading to possible early detection. Due to the constriction of space and the limited function of a unicornate uterus, successful conception, pregnancy, and full term deliveries are complicated by the condition.

While there is no cure for unicornate uterus, conception and successful pregnancies may be possible. However, consistent monitoring of the pregnancy may be necessary.
