Causes of pregnancy disorders in the uterine horns

The occurrence of uterine horn pregnancy is relatively dangerous and can also cause harm to the body. Therefore, for women who experience this condition, when they experience uterine horn pregnancy, they want to fully understand the causes of the disease. In order for you to have a comprehensive understanding, the following is a detailed introduction for many women so that you can have a comprehensive understanding.

Cornual pregnancy refers to the implantation and growth of a fertilized egg in the residual horn of the uterus, which often occurs in primiparas. In addition to the normal uterus, a smaller uterus can be seen, and endometrial lines can sometimes be seen in the uterine cavity. The main causes of cervical pregnancy are as follows. The rudimentary horn of the uterus is a congenital developmental malformation, which is the result of an abnormality in the fusion of the Müllerian ducts during the embryonic period, resulting in incomplete development of one Müllerian duct.

Inflammation

Cervicitis causes the cilia on the surface of cervical endometrial cells to lose their motility and leads to pathological changes such as local stenosis of the cervix, which blocks the fertilized egg in the narrow area and causes cornual pregnancy.

Intrauterine device

It is not easy to conclude whether intrauterine contraceptive devices increase the incidence of cornual pregnancy. It may be related to the different types of intrauterine contraceptive devices, populations and observation methods. However, clinical studies have shown that intrauterine devices can indeed cause cornual pregnancy.

Sex hormone effects

Under normal circumstances, the ratio of estrogen and progesterone is appropriate, which can work synergistically to allow the fertilized egg to be delivered into the uterine cavity through normal ciliary movement and muscle peristalsis of the fallopian tube endometrium. If the balance of estrogen and progesterone is disrupted, cornual pregnancy can occur.

In vitro fertilization and embryo transfer

It may be that the embryo is accidentally injected into the cervix or the embryo migrates from the uterine cavity to the cervix, and certain lesions already exist in the cervix that prevent the embryo from returning to the uterine cavity. In addition, cervical gamete delivery can easily lead to cornual pregnancy. Therefore, the incidence of cornual pregnancy is higher than that of natural pregnancy.

other

Cervical lesions (such as cervical erosion, etc.) or congenital cervical malformations (excessive length, diverticulum, etc.), premature or delayed ovulation can all cause cornual pregnancy. If miscarriage does not occur in the early pregnancy, these symptoms will disappear in the second trimester. In fact, there is no absolute anatomical boundary between cornual pregnancy and normal pregnancy. Therefore, the incidence of cornual pregnancy will be based on the patient's very mild symptoms during early pregnancy, which can only be discovered through further examination. Patients with cornual pregnancy (ectopic pregnancy) often complain of severe abdominal pain around 12 weeks of pregnancy, which may or may not be accompanied by vaginal bleeding, and asymmetric enlargement of the uterus.

As for the cause of uterine horn pregnancy disease, after fully understanding its cause, for the sake of their own health, many women who encounter this situation must go to a large hospital as soon as possible and receive correct treatment to improve their uterine horn pregnancy disease as soon as possible after treatment, so as to ensure their own health.
