Ectopic pregnancy may be caused by some mechanical factors

Ectopic pregnancy may be caused by some mechanical factors, but some people may have it caused by functional factors. Do you know what the common causes of ectopic pregnancy are? Let the authoritative experts explain it to us. I hope that reading this article will be helpful to you.

The main causes of ectopic pregnancy include the following:

1. Functional factors: mainly refers to the time it takes for the fertilized egg to delay entering the uterine cavity.

(1) Changes in fallopian tube activity: Changes in the levels of estrogen and progesterone in plasma lead to changes in the motility of the uterus and fallopian tubes, which in turn lead to changes in the motility of the fallopian tubes. Clinically, some women have ectopic pregnancies after taking pure progesterone contraceptives. (2) Causes of ectopic pregnancy: After the sperm and egg are fertilized in one fallopian tube, due to some factors, the fertilized egg does not move toward the uterine cavity. It swims out of the fallopian tube on the fertilized side and enters the fallopian tube on the opposite side through the abdominal cavity. Due to the long-distance travel, before it reaches the uterine cavity, the fertilized egg has developed to the stage of implantation, so it grows in the fallopian tube on the opposite side. This clinical symptom can explain the saying that the fertilized egg can be found on the opposite side when the corpus luteum of pregnancy is found on one side. As for why the fertilized egg swims outside? This is still a question that has not been explained.

2. Mechanical factors: It is due to mechanical reasons that the fertilized egg is prevented from moving.

(1) Endosalpingitis: Mild endosalpingitis. The lumen of the fallopian tube is not completely blocked, but the lumen is wrinkled and uneven due to mild adhesions, the lumen becomes narrow, and even endometrial depressions are formed. In this case, the fertilized egg is blocked on the way and implants and develops in the original position. According to foreign statistics, 82.4% of patients with ectopic pregnancy also suffer from fallopian tube inflammation, which is caused by obstruction of the fallopian tube. (2) Perisalpingitis: Pelvic peritonitis caused by infection after miscarriage or full-term delivery, and appendicitis. At this time, the lesion occurs in the serosal layer or seromuscular layer of the fallopian tube, causing adhesions around the fallopian tube, and the lumen is twisted and narrowed. (3) Others: If the fallopian tube develops or tumors around the fallopian tube compress the fallopian tube tissue, the fallopian tube will be elongated and the lumen will be narrowed. This is the cause of ectopic pregnancy.

The above is the explanation given by experts on the causes of ectopic pregnancy. I hope it can help you answer your questions. Experts remind everyone that if you suffer from any disease in your daily life, you must not delay treatment. This is very dangerous. Some diseases will worsen or cause other diseases.
