Congenital uterine anomalies are malformations of the uterus that develop during embryonic life. They occur in a small percentage of women and can affect reproductive health. Understanding these anomalies is crucial for diagnosis and appropriate management.
Types of Congenital Uterine Anomalies
· Septate uterus: Normal external appearance but with a division inside creating two cavities.
· Bicornuate uterus: External indentation with two separate cavities.
· Arcuate uterus: Slight indention of the uterine cavity without affecting external appearance.
· Unicornuate uterus: Development of only one half of the uterus.
· Didelphys uterus: Complete separation into two distinct halves.
Causes
In most cases, the exact cause is unknown. Genetic factors play a role, and exposure to diethylstilbestrol (DES) during fetal development increases the risk. However, for the majority, no specific risk factors are identified.
Symptoms
These anomalies are typically asymptomatic but can sometimes cause menstrual pain. They are often discovered during evaluations for infertility or recurrent pregnancy loss.
Diagnosis
A medical history and physical examination may suggest an anomaly, but imaging techniques like ultrasound, hysterosalpingogram, or MRI (magnetic resonance imaging) are necessary for accurate diagnosis.
Treatment
Treatment depends on the type of anomaly and the woman’s reproductive history. Surgical correction may be recommended for septate uteri to improve pregnancy outcomes, while other types often do not require surgical intervention unless specific complications arise.
While congenital uterine anomalies are typically asymptomatic, they can significantly impact reproductive health, increasing the risk of miscarriage or premature delivery. Timely diagnosis through imaging studies and appropriate management, including surgical correction when indicated — can improve outcomes for affected women seeking to conceive.
For those facing challenges due to severe uterine anomalies, such as unicornuate or didelphys uterus, where pregnancy is particularly difficult or risky, surrogacy may be a viable alternative. This option provides hope and an opportunity for parenthood despite reproductive challenges posed by congenital uterine anomalies.
