Analysis of four common causes of ectopic pregnancy

In clinical practice, many patients with ectopic pregnancy are not clear about the causes of ectopic pregnancy and are confused about why they suffer from ectopic pregnancy. So what are the causes of ectopic pregnancy ? Here are some common causes of ectopic pregnancy.

Common causes of ectopic pregnancy include:

1. Chronic salpingitis

Chronic salpingitis can cause adhesion of the fallopian tube mucosal folds, leading to stenosis of the lumen, mucosal destruction, loss of epithelial cilia, adhesion around the fallopian tube, and distortion of the tube shape. The above conditions affect the normal movement and passage of the fertilized egg in the fallopian tube and are the cause of ectopic pregnancy.

2. Fallopian tube surgery

Regardless of whether tubal sterilization is performed by ligation, electrocoagulation or cuffing, if a fallopian tube fistula or recanalization is formed, it may be the cause of ectopic pregnancy. Recanalization or tuboplasty after tubal sterilization may also cause ectopic pregnancy due to scarring that narrows the lumen and poor patency.

3. Abnormal fallopian tube development or function

Abnormal development of the fallopian tube, such as excessively long fallopian tubes, poor development of the muscularis, absence of mucociliary cells, double fallopian tubes, and extra fimbria, can all be causes of ectopic pregnancy. The physiological functions of the fallopian tubes are complex, and the peristalsis of the fallopian tube wall, ciliary activity, and secretion of epithelial cells are all regulated by estrogen and progesterone. If the balance between the two hormones is disturbed, it will affect the transport of the fertilized egg and become the cause of ectopic pregnancy.

4. Pelvic endometriosis

The main cause of ectopic pregnancy caused by endometriosis is mechanical factors. In addition, the ectopic endometrium in the pelvic cavity may have a chemotactic effect on the fertilized egg, prompting it to implant outside the uterine cavity.

The above is an introduction to the common causes of ectopic pregnancy. I hope it will be helpful to everyone. Knowing the causes of ectopic pregnancy can help patients better treat the symptoms and reduce harm.
