How Does Abnormal Uterine Development Occur and the Three Major Hazards of Abnormal Uterine Development

Uterine dysplasia, also known as uterine dysplasia in daily life, is a serious gynecological disease that not only leads to abnormal physical conditions in women, but also affects normal pregnancy. We should pay enough attention to such diseases, and let's take a look together.

What is abnormal uterine development

Abnormal uterine development is the most common type of reproductive organ malformation, and its clinical significance is also significant. During the evolution process, the bilateral accessory mesonephric ducts are influenced and interfered by certain factors, which can stop development at different stages of evolution and form various abnormal uterus. Some patients with uterine malformations may not have any conscious symptoms, and there are no abnormal symptoms in menstruation, sexual activity, pregnancy, delivery, etc., which may be undetected for life or occasionally detected during physical examinations. However, there are also some patients whose reproductive system function is affected to varying degrees until symptoms appear during sexual maturity, marriage, pregnancy, and childbirth.

Types of uterine developmental abnormalities

1. Congenital absence of uterus: The middle segment of the accessory renal ducts on both sides is not developed and cannot synthesize a uterus. Patients often do not have a vagina, but their ovaries develop normally and their secondary sexual characteristics are not affected.

2. Primordial uterus: also known as trace uterus. This is because the development of the accessory renal ducts on both sides stops shortly after merging. This uterus is small, only 1-3 centimeters long, without endometrium, without menstruation, and often without a vagina.

3. Mediastinal uterus: The accessory renal ducts on both sides are closed, but the mediastinum is not degraded. The appearance of the uterus is normal, with two parts of the uterine septum. Incomplete degeneration of the mediastinum leads to the formation of an incomplete mediastinal uterus. When the mediastinum extends to the vagina, it can also form a vaginal mediastinum.

4. Uterine dysplasia: also known as immature uterus. After the merger of the accessory mesonephric ducts on both sides, the development stops for a short period of time. The cervix is relatively long, with a smaller outer opening, and the uterus is normally smaller. There are often infertility, oligomenorrhea, or irregular menstruation.

5. Double angled uterus: Most of the ends of the accessory renal tubules fuse, the mediastinum degenerates, forming a single cervix or vagina, the bottom of the uterus is incomplete, and the outside of the uterus forms a double angled uterus, hence it is called a double angled uterus or saddle shaped uterus.

6. Uniangular uterus: One side of the accessory renal ducts on both sides is fully developed, while the other side is underdeveloped or not fully developed. It can be a residual horn uterus, which means only the uterine cavity has no uterine opening.
