Understand the causes of ectopic pregnancy

Understand the causes of ectopic pregnancy . The onset of ectopic pregnancy is related to many factors, such as endometriosis in women, tubal ligation and recanalization, etc. Understanding these causes of ectopic pregnancy can help women better prevent ectopic pregnancy. So what are the causes of ectopic pregnancy? Let me introduce this issue to you.

The following are the causes of ectopic pregnancy:

1. Chronic salpingitis is the cause of ectopic pregnancy: Under normal circumstances, the fallopian tube can transport the fertilized egg to the uterine cavity through the swaying of cilia and the peristalsis of the fallopian tube smooth muscle. Women with chronic salpingitis have difficulty in getting the fertilized egg to the uterine cavity due to inflammation and pathological changes.

2. Endometriosis is also the cause of ectopic pregnancy: this is because the endometrium in the interstitial part of the fallopian tube is ectopic, causing the lumen to be narrowed or blocked, making it difficult for the fertilized egg to pass through. On the other hand, when the fertilized egg comes into contact with the ectopic endometrium, the syncytial cells differentiate from the cytotrophoblast cells and secrete a mucosal dissolving protease to erode the ectopic membrane, forming a gap for the fertilized egg to implant and develop, thus leading to an ectopic pregnancy in the interstitial part of the fallopian tube.

3. A history of ectopic pregnancy is also a cause of ectopic pregnancy: If you are preparing to get pregnant again, but have not found and eliminated the cause of the previous ectopic pregnancy, the risk of ectopic pregnancy after this pregnancy is higher than that of ordinary women.

4. Hypoplasia or malformation of the fallopian tube is also a cause of ectopic pregnancy: malformation of the fallopian tube muscle layer, lack of cilia in the endometrium and other lesions reduce the function of the fallopian tube in transporting the fertilized egg. Malformation of the fallopian tube also makes it difficult for the fertilized egg to reach the uterine cavity smoothly.

5. The presence of a tumor in the pelvic cavity is an important cause of ectopic pregnancy: due to the squeezing and traction of the tumor, the position of the uterus or fallopian tube is moved, and the structure is abnormal, which will hinder the fertilized egg from reaching the uterine cavity.

6. Another cause of ectopic pregnancy is recanalization after fallopian tube ligation: no matter it is natural recanalization or surgical recanalization, the fallopian tube is not as smooth as before, the recanalization site is relatively narrow, and the fertilized egg is easily blocked and settled in the narrow site.
