Uterine Didelphys

Definition - What does Uterine Didelphys mean?

Uterine didelphys is a condition that occurs when a woman is born with two separate uteri (plural for uterus). Each uterus functions independently from the other, however, the dual presence may complicate each organ's abilities. While uterine didelphys is a rare condition, affected women may struggle with reproductive issues including the increased chance of miscarriage or preterm delivery.

Uterine didelphys is also known as a double uterus.

FertilitySmarts explains Uterine Didelphys

A baby’s reproductive organs develop during the second trimester of his or her mother’s pregnancy. The uterus is formed from two tubes that join together to shape one hollow uterus. In cases of uterine didelphys, each of the tubes develops independently. As a result, two uteri form. Each uterus may have its own uterine horn and cervix. In some cases the vagina may also be divided in half by the presence of a thin wall of tissue. This is called a double vagina.

Cases of uterine didelphys are often unnoticed as the condition is typically symptom-free. The presence of a double vagina may result in pain during intercourse, as penetration may compress the abnormal vaginal walls. Additionally, women unaware of a double vagina may find tampons ineffective, as the flow from the second vagina would not be blocked. Most cases of uterine didelphys are diagnosed as a result of infertility testing. Pelvic exams and imaging scans can be used to diagnose the condition.

Uterine didelphys increases the risk of recurrent miscarriages or the inability to carry a pregnancy to term, as the decreased size of the uterus limits the space available for a fetal development. However, many successful pregnancies are facilitated through careful physician monitoring and lifestyle adjustments. While most cases of uterine didelphys do not require any treatment, a double vagina may be removed if it causes pain, discomfort, or psychological distress. A double uterus is rarely surgically adjusted.
