Some functional factors may cause ectopic pregnancy

Some functional factors may cause ectopic pregnancy, but many people do not know what functional factors are. In fact, this mainly refers to the delay in the time for the fertilized egg to enter the uterine cavity. So what are the other causes of ectopic pregnancy ? The specific contents are as follows.

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 plasma estrogen and progesterone levels lead to changes in uterine and fallopian tube motility, which in turn causes changes in fallopian tube motility. Clinically, some women have developed ectopic pregnancies after taking pure progesterone contraceptives.

(2) The fertilized egg wanders outside the fallopian tube: 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 wanders outside 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 wanders outside the fallopian tube when the ovum is pregnant on one side, but the corpus luteum of pregnancy can be found on the opposite side. As for why the fertilized egg wanders outside, this is still a question that has not been explained, and it is also the cause of ectopic pregnancy.

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

(1) Fallopian tube endometritis: In mild fallopian tube endometritis, the lumen of the fallopian tube is not completely blocked, but the lumen is slightly adhered, causing the endometrium to be wrinkled and narrowed, and even forming endometrial concavities. In this case, the fertilized egg is blocked on the way and implants and develops in the location where it is located. 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, which is also the cause of ectopic pregnancy.

(2) Perisalpingitis: infection after miscarriage or full-term delivery, pelvic peritonitis caused by appendicitis. In this case, the lesion occurs in the serosa or seromuscular layer of the fallopian tube, causing adhesions around the fallopian tube and twisting and narrowing of the lumen.

(3) Others: Tumors that develop in the fallopian tube or around the fallopian tube compress the fallopian tube tissue, causing the fallopian tube to lengthen and the lumen to narrow. 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.
