"What is a unicornuate uterus?"

ZocdocAnswersWhat is a unicornuate uterus?


My wife had a severe problem with her first pregnancy several years ago due to a unicornuate uterus. We've definitely decided to have a child together, so what sort of risk does this unicornuate thing represent? Is there a type of surgery she can get to compensate for this?


A unicornuate uterus is a rare type of uterine anomaly. A unicornuate uterus is characterized by the connection of only one fallopian tube to the uterus. This is anomaly occurs very early in the female development, but is often not discovered until later in a women's life when she has some imaging of her pelvis. In terms of pregnancy, woman with a unicornate uterus may have a little more trouble getting pregnant, but the majority of able to conceive naturally. Unfortunately, there are high rates of pregnancy complications including higher rates of ectopic pregnancy, higher rates of spontaneous abortion (miscarriage), preterm delivery, and fetal death within the uterus. This is not to say that you and your wife will not be able to have a healthy pregnancy, you just will have to be looked after more closely for complications. There are some procedures that may be able to reduce these risks depending your wife's particular anatomy. I suggest that you have your wife schedule an appointment with her OBGYN that she wants to use for her pregnancy. You may consider consulting with a maternal fetal specialist, an OBGYN that has done extra years of training in high risk pregnancies. He or she can discuss your absolute risks throughout a pregnancy with respect to preterm birth, miscarriage, intrauterine death, and other complications.
