Two main causes of ectopic pregnancy

The harm caused by ectopic pregnancy to female friends is no less than other gynecological diseases, and understanding the causes of ectopic pregnancy is helpful in preventing it. So, what are the causes of ectopic pregnancy ? Next, let the experts introduce to you the causes of ectopic pregnancy.

1. Functional factors that lead to ectopic pregnancy: mainly refers to the delay in the time for the fertilized egg to enter 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 developed 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 concavities are formed. In this case, the fertilized egg is blocked on the way and implants and develops in the location where it is. According to foreign statistics, 82.4% of patients with ectopic pregnancy also suffer from fallopian tube inflammation, which is caused by the obstruction of the fallopian tube. (2) Perisalpingitis: Infection after miscarriage or full-term delivery, pelvic peritonitis caused by 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 is elongated and the lumen is narrowed. This is one of the causes of ectopic pregnancy.
