Introduction

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.

Generally, an irregular uterine shape refers to abnormal structural changes observed during ultrasound or other imaging examinations, differing from the normal uterine形态. Detailed analysis is as follows:

If caused by congenital factors, it is usually due to abnormal uterine development during embryogenesis. This is commonly seen in uterine malformations such as bicornuate uterus, septate uterus, and rudimentary horn uterus. These morphological changes are typically present from birth, and some women may experience no obvious symptoms, with normal menstruation and sexual activity. However, such conditions may affect fertility and increase the risk of miscarriage and preterm birth. Enhanced prenatal monitoring is necessary during pregnancy.

Irregular uterine shape caused by acquired factors is often associated with diseases. For example, uterine fibroids can cause localized protrusion and deformation of the uterus, while adenomyosis leads to uniform enlargement and irregular contours. Uterine trauma or post-surgical scarring can also alter uterine morphology. These conditions are often accompanied by symptoms such as heavy menstrual bleeding, abdominal pain, and infertility. Treatment options, including medication or surgery, should be selected based on the specific condition.

There is no need to panic upon discovering an irregular uterine shape. It is important to seek timely medical evaluation at a hospital to determine the underlying cause. A suitable management plan should be developed based on individual symptoms, fertility needs, and medical advice, with regular follow-up examinations. Maintaining healthy lifestyle habits and avoiding excessive fatigue and adverse stimuli are also recommended in daily life.

What should be done if the gestational sac is 5 mm away from the scar?

Under normal circumstances, scars refer to uterine scars. A gestational sac located 5 mm away from the scar may be caused by random implantation of the fertilized egg, abnormal uterine morphology, uterine scar diverticulum, adenomyosis, intrauterine adhesion syndrome, or other similar reasons. Treatment options include general management, medication, and surgical treatment, which should be conducted under a doctor's guidance.

Can I get pregnant and have a baby if I have adenomyosis?

Whether patients with adenomyosis can conceive and deliver depends on the severity of the condition and the patient's overall health status. In cases of mild disease where the shape and environment of the uterus are not significantly affected and the woman's ovarian function is normal, pregnancy may be attempted, although regular follow-up is required. However, in severe cases with abnormal uterine morphology, impaired ovarian function, and inability to ovulate normally, normal conception and delivery may not be possible.

Can a childlike uterus become pregnant?

Whether a rudimentary uterus can achieve pregnancy depends on the severity of the condition. In mild cases, where there is minimal alteration in uterine morphology, no significant impact on the uterine environment, and normal ovarian function, timely treatment may allow for the possibility of pregnancy. In severe cases, where uterine shape and environment are significantly affected and ovarian function is abnormal, pregnancy is considerably more difficult, and surgical intervention may not be able to rectify the situation.
