What are the main causes of ectopic pregnancy?

The occurrence of ectopic pregnancy is a problem for female friends, and the harm caused by ectopic pregnancy to patients is also very great. In order to reduce the occurrence of ectopic pregnancy, we should understand the causes of ectopic pregnancy. So what are the main causes of ectopic pregnancy? Let's learn about the causes of ectopic pregnancy.

The main causes of ectopic pregnancy are as follows:

First: The relationship between the placement of intrauterine contraceptive devices and ectopic pregnancy. The increased incidence of ectopic pregnancy may be due to salpingitis after using IUD. However, it has been recently shown that IUD itself does not increase the incidence of ectopic pregnancy, but if contraception fails and conception occurs, the chance of ectopic pregnancy is greater.

Second: Women who have had tubal pregnancy after tubal surgery are more likely to have tubal pregnancy again. Due to the influence of the original tubal lesions or surgical operations, the incidence of tubal pregnancy again after any surgery is about 10%-20%. For infertile patients who have undergone tubal separation and adhesion surgery, tuboplasty surgery gives them the opportunity to get pregnant, but also the possibility of tubal pregnancy.

Third: Tubal inflammation can be divided into tubal mucositis and perisalpingitis, both of which are common causes of tubal pregnancy. Severe tubal mucositis can cause complete blockage of the lumen and lead to infertility. In mild cases, although the lumen is not completely blocked, adhesions of mucosal folds occur, narrowing the lumen, or cilia defects affect the normal movement of the fertilized egg in the fallopian tube, causing it to be blocked midway and implanted there.

Fourth: Fallopian tube dysplasia or abnormal function Fallopian tube dysplasia is often manifested by excessively long fallopian tubes, poor myometrial development, and lack of mucociliary cells. Other causes include double fallopian tubes, diverticula, or parafimbria, which can all be causes of tubal pregnancy. The function of the fallopian tube is regulated by estrogen and progesterone. If the regulation fails, the normal operation of the fertilized egg will be affected. In addition, mental factors can cause spasm and abnormal peristalsis of the fallopian tube, interfering with the transportation of the fertilized egg.

Other fallopian tubes are compressed by surrounding tumors such as uterine fibroids or ovarian tumors, which sometimes affect the patency of the fallopian tube lumen and hinder the movement of the fertilized egg. Endometriosis can increase the possibility of the fertilized egg implanting in the fallopian tube.

The above is the cause of ectopic pregnancy introduced by experts. Do you understand it? If you find ectopic pregnancy, go to the hospital for examination and treatment as soon as possible.
