The womb (uterus) may form abnormally in about 3-4% of cases. There are many different classification systems used to describe the numerous different types of congenital uterine abnormalities that exist. The American Society of Reproductive Medicine (ASRM) classification is commonly referenced by clinicians. The picture above shows a few examples of how the uterus can develop abnormally.
It is a very challenging area of fertility that has been researched and debated extensively. If you have fertility problems then you are more likely to have a uterine anomaly. A fertility specialist will always assess whether the female reproductive organs (cervix, womb and ovaries) appear structurally normal with an internal vaginal ultrasound scan. Whilst it is uncommon for uterine anomalies to affect women, they are more common in the infertile population.
Treatment options are few and the requirement for surgical correction is also hotly debated and remains inconclusive. Many people with uterine anomalies can conceive naturally and have success in IVF cycles. It is important to discuss your specific circumstances with a fertility specialist if you are diagnosed with a uterine anomaly.
