Introduction

In general, congenital double uterus, typically refers to a rare developmental abnormality of the female reproductive system. This condition means that during embryonic development, the two uterine structures that should have fused into a single uterus fail to completely merge, resulting in the formation of two separate uteri. To avoid potential health risks, it is recommended to undergo regular examinations and evaluations under the guidance of a qualified physician.

Generally, congenital double uterus refers to a rare developmental anomaly of the female reproductive system. In this condition, the uterus, which should have fused into a single organ during embryonic development, fails to fully merge and instead forms two separate uteri. A detailed explanation is as follows:

Congenital double uterus is a congenital malformation characterized by abnormal uterine development. It arises from the failure of the two Müllerian ducts to fully fuse during embryonic development, resulting in the formation of two separate uterine bodies, cervixes, and vaginas, often accompanied by either a double cervix or a single cervix. Imaging studies reveal two distinct uteri within the pelvic cavity, each with its own uterine cavity and endometrium. Some patients may also have a vaginal septum or oblique vaginal septum. Most individuals with a double uterus experience no significant symptoms, and menstrual cycle and flow can remain normal. However, some may encounter fertility-related issues due to abnormal uterine morphology, such as infertility, miscarriage, preterm birth, or fetal malposition. In certain cases, delayed pregnancy diagnosis may occur due to the possibility of alternating pregnancies between the two uteri.

To avoid health risks, it is recommended to undergo regular examinations and evaluations under the guidance of a specialist. Monitoring menstrual status in daily life and avoiding strenuous physical activity or improper sexual behavior can help reduce the risk of complications.

What is a bicornuate uterus?

In general, a double uterus may be caused by abnormal development of the Müllerian ducts, genetic mutations, maternal exposure to teratogens during pregnancy, congenital rubella syndrome, Turner syndrome, or other factors. Patients should seek timely medical attention at a reputable hospital to identify the underlying cause and receive appropriate treatment. If necessary, treatment may involve undergoing a uterine reconstructive surgery at a正规 hospital. In daily life,

Can a bicornuate uterus allow for normal childbirth?

In general, whether a woman with a T-shaped uterus can have a normal pregnancy depends on the severity of the uterine malformation. It is recommended to seek timely medical attention, identify the underlying cause, and undergo symptomatic treatment under a doctor's guidance. To avoid reproductive risks, it is advised to undergo detailed examinations under the guidance of a specialist in obstetrics and gynecology and develop a treatment plan based on individual circumstances.

What does it mean if the shape of the uterus is irregular?

If caused by congenital factors, it is often due to abnormal uterine development during the embryonic stage, commonly seen in uterine malformations such as bicornuate uterus, septate uterus, and rudimentary horn uterus. These structural changes in the uterus are usually present from birth. Some women may have no obvious symptoms, with normal menstruation and sexual activity, but these abnormalities may affect fertility and increase the risk of miscarriage and preterm birth. Prenatal care monitoring should be enhanced during pregnancy.

What does a bicornuate uterus mean?

In general, a bicornuate uterus is a congenital uterine malformation and is considered a type of uterine developmental abnormality. Diagnosis and treatment of a bicornuate uterus should be conducted under the guidance of a qualified physician; patients should avoid self-diagnosis or blind treatment. Women who plan to become pregnant are advised to undergo comprehensive reproductive system examinations before conception to assess uterine morphology and function, and to develop an individualized fertility plan.
